m i 1-1 l I l 1.0 Introduction 1.1 Rationale and 1.cgal Requirements In order to satisfy the requirements of the Federal Clean Water Act (PL 922500) and the Missouri Clean Water 1,aw (Chapter 204 RSMo (Supp. 1973)), Union Electric must assess the potential impacts of its callaway Plant intake facility on the Missouri River fish popu la t ion. This assessmert is required as part of the National Pollutant Discharge Elimination System (NPDES) permit issued by the Missouri Department of Natural Resources (DNR) on August 8, 1980 and reissued on November 22, 1965. This NPDES permit (MO-0098001) required Union Electric to submit a study program to monitor the effects of operation of the plant intake st ructure on the fish of the Hissouri River. This study was designed to insure utilization of best available intako technology (BAT) to achieve minimum adverse environmental impact on the aquatic ecosystem, as specified in Section 316(b) of the Clean Water Act. A Scope of Work for this study was submitted to the DSR on November 24, 1980 and was approved on December 10, 1980. The Scope of Work was modified in January, 1984, to take into considcration the results of two years of comprehensive aquatic study perf ormed in the vicinity of the Callaway intake (Camp, Dresser & McKee 1981, 1982). The two year aquatic monitoring ef fort was carried out to satisfy the requirements of the U. S. Nuclea r Regula tory Commission. 1 1
. l 1-2 l The Callaway 316(b) study was f ormulated based on inputs from the following sources:
o The requirements of Section C of the Callaway NPDES g pemit as issued by the Missouri DNR g o The Scope of Operational Fish Impingement and Entrainment Studies, Missouri River, Callaway Power Plant, which was reviewed and approved by the DNR o A field audit of the Scope of Work conducted by the DNR E in October,1980, at the Callaway Plant 5 o The 1977 316(b) " Guidance Document" (U.S. EPA 1977) o The 316(b) demonstration f or Union Electric Cottpany's Rush Island Power Plant (UE 1979b) 1.2 Previous Studien The Missouri River in the vicinity of the Callaway intake has I been extensively studied. These studies were done to assess the health of the aquatic environment prior to plant construction and to identify any impacts of construction. The baseline studies were perf ormed by Dames and Moore, Inc. from 1973-1975. These studies were a comprehensive analysis of the terrestrial and aquatic environment near the Callaway Plant (Union Electric Co. 1974, 1975, 1976). A construction period water quality monitoring program was carried out by Ryckman, Edgerley, Tomlinson and Assoc. (RETA: now Envirodyne Engineers) f rom June 1976 through November 1979 (Union Electric Co. , unpublished) .

Preoperational studies were performed on the aquatic ecosystem near Callaway by Camp, Dresser and McKee, Inc. (CDM) from June 1980 through !by 1982 (CDM 1981,1982). Union Electric Company's I I

I 1.3 Study Element s I The Callaway 316(b) field studies conducted during 1984-1996 g consisted of three rajor component s: entrainment, impingement and l3 field fisheries. The entrainment study estimated density, composition, and spatial and temporal distribution of fish larvae and eggs in the Missouri River adjacent to the Callaway Plant intake. These estimates were then combined along with hydrological data to estimate numbers and percen age of icthyoplankton entrained by the intake, both with ac tual flows and with record low flows during the I I
1-4 I period of *prval fish occurrence. The impingement study involved counts and measurements of finpinged fish. These counts were combined with intake operating data to estimate total numbers of fish impinged and identify any compositionc1 or seasorial trends. The field fisheries survey involved sampling of adult fish populations adjacent to the intake to gain insight into the dynamics of these communities. I These data were used to compliment and augment the entrainment and impingement studies and thus help demonstrate best available technology and minimal adverse environmental impact relative to intake design and operation. 1.3.1 Entrainment I The entrainment study included weekly samples f or 26 I consecutive weeks f rom April through September 1984 Three paired subsurface hauls were made in each of three sones in the Missouri River between mile !!$.4 and 116. Intake withdrawal rates along with river discharge estimates were combined with icthyoplankton data to compute entrainment as a percentage of total river icthyoplankton transport. 1.3.2 Imp in g ea .i n t The implagement study consisted of weekly random-day collections of screen backwash water for an entire year (February 1985 through January 1986) . Each collection was approximately 24 hours in length. Intake screens were operated in their normal manner during the collection period. Each collection yielded numbers and weight by species of fish impinged. The impingement counts were then combined I
I 1-5 I with plant operating records to estimate total monthly and annual impingement rates. 1.3.3 I rield Fisheries The field fisheries study was designed to provide inf ormation on the composition and population dynamics of the fish population in the vicinity of the Callaway Plant f or assessing the significance of potential entrainrtent and impingement tropa c t s. The field fisheries study was conducted monthly for one year concurrent with impingement sampling. 1.4 Sutwary of Conclusionn I The Draft Section 316(b) Guidance Kinual defines low potential impact intakes as "those located in biologically unproductive areas having low flow or having historical data showing no effect or for which other considerations indicate low (adversa environmental) impact." The Callaway Plant intake structure is Jocated in a biologically unproductive area and is a low flow intake since the plant withdraws only nake-up water for a natural draf t coo 11ag tower system. The entrainment and impingement studies of the Callaway intake confirmed that it is located in biological umproductive area and has low adverse environmental impact. This I conclusion is based on the following considerations. The entrainment study sarnpled a total of 43,314 m8 of river water during the study. The larval entrainment study indicated that endangered, threatened, and rare fish species are not being entrained
i 1-6 by the Callaway intake. Those species of larvae collected during the I en t rait. *tudy are common to the Missouri River which was confirmed by the field fisheries study. Mean percentage entrainment estimates peaked at less than 0.15% of larval transport using actual discharge estimates on sampling days. Worst case entrainment estimates using historical record low f1ws for April through September f rom 1929 through 1980 did not exceed 0.75% of the larvae being transported in the Missouri River. The entrainment of icthyoplankton by the Cellaway intake structure should have minimal ef fects on the fish populations of the Missouri River. Impingement sampling at the Callaway intake collected a total of 13 species of fish and sampled 1,933,932,000 gallons of river water. The projected total annual impingement was estimated at 2410 fish weighing $9.5 kilograms (131.2 pounds) . Gizzard shad (92.7%) and freshwater drum (3.4%) accounted for 96.1% of individuals projected to be impinged annually. No other fish species were projected to be impinged in numbers greater than 18. Endangered, threatened, or rare fish species were not collected during the impingement study. The extremely low projected impingement rates can be attributed to the design, construction, capacity, and location of the Callaway intake structure. These low projected impingement rates for the Callaway intake structure reflect the use of the best technology available for minimizing impingement by a cooling water intake structure. The impingement study has shown that the impingement impact is not significant enough to adversely af fect the fish populations of the Missouri River. I I
m 1-7 L 1he field fisheries study f ound that the two daninant species in the electrofishing collections were gizzard shad and f reshwater drum. These two species accounted f or 46.1% of the total speciment- - projected to be impinged annually. The other species in impingement sampics were less dctninant in abundance which was consistent with their lower atundance f ound in the field fisheries study. Feeding, spawning, and nursery areas f or fish are limited in the area of the intake structu re. The lov impingement rates indicate that the intake structure wa s located and designed to minimize impingettent since the field fisheries study has shwn that fish do reside in the area. I The low projected impingement rates and the small percentage of larvae being entrained can be attriluted to the design, construction, capacity, and location of the callaway intake structure. l.osses are not of a suf ficient magnitude to significantly af f ect the fish populations of the Missouri River. The Callaway intake structure reflects a "best technology available f or minimizing adverse environmental impact" in cutpliance with Section 316(b) of the Federal Clean Water Act and the Missouri Clean Water Law. 1.5 P.eport St ruc ture This report deals first with the intake structure's location and operation specifica.

I 2-3 l 2.3 Intake Structure Description and Operat ton 2.3.1 Intake St ruc tu re De sc ript ion The Callaway plant water intake structure is located on the north bank of the Missouri River at river alle (RM) 115.4 (Figure 2.2), about 3500 f eet upstream of the confluence of Lot;an Creek with the Missouri River. The intake structure is located within an opening of the Corps of Engineers' rock revetn.ent and breakwater between RM 115.34 and 115.45. The upstream river bank is set back slightly f rom the riverside face of the intake structure and the rock revetment. The dwnstream river bank is set back f rom the r oc k revetments, which allows placement of a low velocity fish escape opening on the d wnstream side of the intake. To protect the intake structure f rom barges, pipe pile clusters are installed on the upstream side. The main channel of the Missouri River flows directly in front of the intake structure as the channel follows the north shore of the river at this point. I The intake structure is r.nde of reinf orced concrete and is composed of a pump room section and an electrical equipment room section (see Appendix A). Plan and section views of the intake are shown in Figures 2.3 and 2.4, respectively. The floor of the intake structure is at elevation 486 feet above mean sea level (MSL). The operating level of the intake is at elevation 541.5 feet MSL, 2.5 feet above the 200 year flood elevation. I I I

~ ~ 2-7 - Features of the three-bay, three pump intake st ructure are shown in Figures 2.3 and 2.4. Incoming water initially passes through a set of vertical trach racks designed to stop large objects and debris from entering the intake structure. The trash racks are constructed cf 0.5 inch bara placed 3 inches on center. Sand gates can be inserted s between the trash racks and stop gates. The sand gates minimir.e intake bay silt deposition. Intake stop gates are located between the nand gates and traveling screens. The stop gates provide intake bay isolation for mintenance pu rposes, k'ith a stop gate closed, an intake bay can be dewatered by portable dewatering purnps. These gates include a Limitorque operator equipped with a mnual handwheel. A fish escape stop is also used for dewatering. These ga tes operat e identically to the intake stop gates. A vertical traveling screen is located in each of the three pump bays. The traveling screens are a loop of screen panele that are driven over a pair of head sprockets and down through a boot. The screen pancis are constructed of 0.5 inch square mesh screen wire. The intake structure is constructed with fish escape openings in the side walle of the pump hays. These openings are directly in front of the traveling screens. The fish escape openings are 3 ft. vide and 10 ft. high, topping at 496 feet MSL (see Figure 2.4). The intake structure houses three Ingersoll-Kand pumps that provide raw Missouri River water to the Callaway water treatment plant. Figure 2.5 shows a typical pump and motor on the min floor

2-9 level. The comn2on discharge nanif old is one level down from the noin fl oor . These pumps are vertical three-stage centrifugal pumps. The [ impellers are enclosed; the firt.t stage inpeller has double suction L for thrust balance. Pump suction pressure is n'.5 poi and discharge pressure is 195 psi. The pump delivers about 14,000 gpm. The pump motor is 3-phase, 4160V and 60Hr. It develops LOSO lip and operates at 1185 rpm. The suction head bearings and all other bearings are water lubricated. A mounting flange (part of support head) suppor t s the { pump vertically. The pump driver is mounted on the support head. The driver is coupled to the upper shaf t by a rigid adjustable coupling. Stage casings contain the casing bearings which prevent unwanted radial puep shaf t motion. Lach casing encloses dif fusor passages. These passages convert fluid velocity to pressure. Two ten-inch f ree discharge valves control transient surge pressures of water being puc: ped from the Missouri River to the water treatment plant. Each valve is of the fixed-cone, discharge regulating type. The valves act as a continuously modulating by-pass ( to control the variables of system flow. Lach valve can handle 10 0 *.' of system regulation. Thus, the other valve remains on standby. The l valves are designed to dissipate fluid energy rapidly. Each discharge valve consists of a 45 degree cone attached to the unin body cylinder by four independent ribs. Flow through the valve is regulated by cleans of a moveable sleeve mounted on the valve body. Sleeve movement varies the size of the annular port. Thus, flow through the valve is directly proportional to the stroke of the sleeve. tovement of the sleeve is controlled ~oy two hydraulic oil
2 - 10 cylinders. 1he cylinders are attached to the downstream end of the upper weldment. The weldment functions as a transition piece between the 14" header pipe and the 10" valve. The kinetic energy of the water through the valve in rapidly dissipated by a drop pipe. Dissipation occut s due to friction and turbulence incurred by the drop pipe. I An electro-hydraulic control system maintains valve positions without drif t and closes the valves on an all-pump trip signal or loss of power to the servo-controller. The excess water frts the f ree discherge valves is diverted to the free discharge box on ti e dovntream side of intake structure. The excess water is discharged ths 3 ugh a pipe in the bottom of the free discharge box back into the river. The amount of water disch rged from the free discharge box is the amount of water which is not necessa.y to maintain system prassure. The intake structure has two types of systems to provide f reeze protection f or the intake. Electric boilers warm stilling basi , water and spray wash heaters warm screen wash water. Two Coates electric boilers provide shell ride boiler heat exchanger water. The shell side water vams incoming stilling basin water, which flows to the intake pump bays for f reeze protection. These boilers are designed for heatinj to 5000 KV. using a 3-phase, 60 Hz power system at 4160 volts. l I
2 - 11 2 Two horizontal shell, tube-type heat exchangers provide a heat ' i transf er interface between boiler and " stilling basin to pump" bay water. I Three in-line electric heaters warm screen wash water for f reeze protection. One heater is provided for each traveling screen. These heatet s are used when temperature requirements dictate. The heaters are 120V, single phase, 60 Itz and generate 200 MW of power. 2.3.2. Intake Operation i Two intake pumps will normally satisfy plant load requirement s. , i During periods of outages only one puu.p will be operated to provide
- water for essential plant services.
The f ollowing equipment is operated automatically to allow sequencing circuits to place the equipment in the proper configuration , upon intake pump starting and stopping: Stop gates and fish gates Intake pumps and respective hydraulii. discharge valves Desilting valves l Traveling screen wash valves Traveling screens operated in forward mode l Lube water pumps l Trash handling procedures involve both river currents and I mechanical systems. The larger trash or debris carried by the river. l which accumulates on the coarse trash rack, is carried away by the river currents and changes in river elevation. l
2 - 12 Traveling screens block debris and trash small enough to pass through the coarse trash rack and prevent it from entering the pump wells and consequently the pumps. Any debris larger than 1/2 inch square is collected on the trave' ling screens. Whenever accumulated debris on the screens produces a predetermined head differential across the screens, the screen wash systems operate automatically. The screen waeh systems also are operated via an automatic periodic timer on an eight-hour cycle to prevent the boot shaft at the lover end of the screens from " mucking in". The screen systems shut off automatically after a preset minimum period of ti a The heaviest periods of operation for the traveling screen I systems are in the fall and spring seasons. At these times debris in the river is at a maximum due to either shedding of leaves or rain and high water which wash out the backwater areas and streams along the 141ssouri River. During these periods the acreens may operate continuously to prevent trash buildup. A pump bay warming system and inline heating system provide traveling screen freeze protection and deicing of screen components. The warming system actually minimizes ice formation, while the in-line heaters loosen and knock ice already formed from the screens. Operator judgment is required to determine whether one or two 4 boilers should be placed in operation. However, formal system , alignment is for two trains of water warming, each train consisting of one boiler, one heat exchanger, and one recirculation pump. l 1 I
2 - 13 s Heavy ice buildup on the traveling screens may result in considerable damage to screens and baskcts. The in-line heaters are run automatically when f reezing or subf reezing temperatures are predicted. The heaters energize when intake bay water temperature is F 33*F. Normal system alignment is each in-line heater serving each respective screen. However, by proper valving, any heater can supply any or all screens. The Callaway intake structure has been designed f or low intake velocities. The maximum intake-water velocity at the screens is estimated to be 0.6 f t/s at the 1-day 30-year low Missouri River fic'w of 5500 cfs (at 495 f t. MSL). Maximum velocity at the screens during the minimum river navi Eation flow of 35,000 cf s (at 501 f t. MSL) will be about 0.3 ft/s. Each intake pump's stop and fish gates are normally open when the intake pump is operating. The gate positions are reversed when an intake pump is stopped. Intake pumps A and B include similar l circuits. However, to open the B fish gate, stop gates B and C must be open; to open the A fish gate, stop gates A and B must be open. These configurations prevent fish from being trapped in the bays, i The purpose of the f ree discharge valves is to maintain system pressure at 195 psig. Each valve is capable of 100% system regula tion; therefore, one valve is operated in automatic while the second valve remains on standby. The 195 psig setpoint is established with an instrument located near the annunciator panel. Tne valve
2 - 14 i control circuit compares setpoint with intake pump discharge header pressure and positions the free discharge valve as required to maintain this setpoint. 2.3.3 Intake Hydraulics and River Hydrology I The main channel of the Missouri River is adjacent to the north shoreline in the area of the Callaway intake. The intake structure is located along the river bank so that make-up water is drawn from the main channel perpendicular to the dominant flow field of the river. Flow fields in the main channel of tre river are turbulent due to the volume of water flowing, the velocity of the current, and changes in the river bottom contours. The area in the river from which the make-up water is drawn may be defined as the
" zone of influence" of the intake structure.
The physical presence of the intake structure, in addition to its water withdrawal, af fects the natural flow field of the river. The area behind the intake structure has been built up, forcing the river to flow around the front of the intake structure. This slight narrowing of the river forces the water along the north shore to pass in front of the intake and has increased the river current velocity there. A slow eddy current is caused by the downstream corner of the intake. Aside from this small zone of influence, there are no changes W in flow field resulting f rom intake structure configuration. At any given time the zone of influence is determined by the quantity of water withdrawn and the river flow. It can also be affected by the :ombination of intake water pumps which are operating. I
2 - 15 Due to these variables, the zone is not constant at all times and under all operating conditions. Since the intake withdrawal rate is [ small even during periods of low flow, the zone of influence is a
'small area near the bottom of the main channel of the river.
2,3.4 Entrainment and Impingement Consideratiens The design and construction of the intake structure includes several features designed to minimize or reduce impingement and _ entrainment. To minimize impingement, the size of the intake portion of the structure has been increased beyond the required design in order to reduce the velocities of intake water through the screens. Also, to minimize entrainment and impingement, the intake has been located so it protrudes into in the main river channel, and water is withdrawn f rom areas located away from shallow and slower moving water where the largest populations of aquatic organisms would be expected to occur. Water withdrawal by the intake occurs from the depths of g the main channel where few organisms inhabit. This gives buoyant or g _ semibu oyan t orgamisms a lesser chance of entrainment. In addition, the face of the intake has been aligned parallel to the river flow so , that the water is withdrawn perpendicular to the river flow. Thus, river currents tend to sweep river organisms past the intake structure. Finally , the deicing system at the intake structure and its spray nozzles have been located so that icing can be controlled at the-structure and any thermal attraction will be negligible. Thus, any heat dissipated at the intake structure will be mixed rapidly and reduced within the area of the intake s t ru c tu re . Also, a portion of the water pumped will be discharged immediately back to the river from
2 - 16 I the free discharge valves. This will immediately return some of the entrained organisms back into the river. The portion of river flow withdrawn by the intake st ructure is an important consideration for both impingement and entrainment. The percent of river flow withdrawn by the plant is minimal, as shown by Table 2.1. This low volume withdrawal helps minimize the number organisms exposed to any adverse ef fects caused by the operatica of the intake structure. I I I I I I I I I I I I

3-1 I 3.0 River and Site Characteristics 3.1 Physical and Hydrological 3.1.1 IntroJuction The Missouri River in the vicinity of the Callaway intake is typical of the lower Missouri. High turbidities of up to 6980 Jackson Turbidity Units (JTU) have led to this river being referred to as the
" Big Muddy". Strong currents, fluctuating water 1cvels, and shif ting, unstable substrates result in a low diversity of habitat types f or aquatic organisms. Few permanent islands, backwaters and side channels remain in the area due to man's activities of the la s t 150 years. Quiet water areas are restricted to areas behind dikes at normal river flows.
The lower Missouri River has been radically altered over the la st century and a half. Construction and maintenance of a 9 foot deep, 300 f oot wide navigation channel has resulted in drastic reductions in water surface area and island, chute and backwater habitats. Snag removal, dredging, installation of revetment, pile dikes, and rock dikes, and flow regulation froc main ctream reservoirs i have all contributed to these reductions. Since 1879, *.he 31 mile stretch between Hermann, Missouri and the Osage River has had a 41% reduction in water surface area and a 99% reduction in unconnected island surface area (Funk & Robinson 1974) . Reduction of islands, sandbars and chutes is most notable in areas like the area across f rom Portland, Missouri (Funk & Robinson 1974) . I I
3-2 Almost 1500 reservoirs occur in the Missouri River drainage above Sioux City. Iowa and they provide over 111 million acre feet of storage capacity. Flows are regulated from these dams to provide between 31,000 cubic feet per second (cfs) and 41,000 cf s at Kansas City, Missouri during the navigation season (Slizeski _e_t, t al.1982) . 3.1.2 Hydrology I The Missouri River flows southeasterly f rom Three Forks, Montana f or 2315 miles, draining about 529,000 square miles before joining the Mississippi River near St. Louis, Missouri. The nearest gauging stations to the Callaway intake are the U.S. Geological Survey stations at Hermann and Booneville, Missouri. At the Hermann station, 17 miles downstream of the intake, stream flow records have been kept since 1897. The average flow over an 86 year period (1897-1983) was 80,050 cfs. However, because of the channel alterations and flow regulation since 1952, flow records prior to 1952 may not be representative. Daily discharge means and ranges by month are presented in Figure 3.1. At Booneville, 82 miles upstream from the intake, stream flow records have been kept since 1925. Average flow f or a 58 year period (1925-1983) was 59,260 cf s. The Hermann gauge is closest to the Callaway intake.

3-5 Temperatures in the vicinity of the Callaway intake on days when icthyoplankton samples were collected are presented in 6 Section 4.4.1, 3.1.3 Logan Creek Logan Creek is a small tributary to the Missouri River which enters just downstream of the Callaway intake at river mile 114.9. It is intermittent during droughts and is essentially a backwater at high Missouri River elevations. 3.1.4 Other Fujor Tributaries L Upstream of the intake, the closest major tributary is the Osage River at river mila 130. Osage River flow is largely dependent on discharges from Bagnell Dac at Lake of the Ozarks. Osage River i discharge ranges f rom 373 cf s to 216,000 cfs with an average of 9937 cfs for the period 1937-1983 measured at St. Th oma s , Mi s s ou ri . - Downstream of the intake, the closest major tributary is the Gasconade River. Flows at Jerome, Missouri range from 254 cf s to 136,000 cfs, with an average of 2485 cfs for the periods 1903-1905 and 1922-1983. 3.2 Water Quality The Missouri River in the vicinity of the Callaway intake structure is a swif tly flowing, turbulent river with a high level of suspended sedimerc. The river experiences heavy silt loading from erosion and ruFof f during storms. The Missouri River has become less
l 3-6 w l turbid since 1945, when the Rivers and Harbors Act authorized major navigation, bank stabilization and reservoir construction projects. However, the Missouri is still a highly turbid river characterized by 1 l periodic heavy silt loading, swif t currents, shif ting and unstable substrates, and greatly fluctuating water levels. The water quality of the Missouri River near the Callaway intake is influenced by agricultural runof f, industrial and municipal discharges (CDM 1981, 1982). Fluctuations in the river's flow have been shown to influence the chemical constituents of the river. Increased river ficvs (volume) cause lower levels of dissolved solids, chloride, BOD and sulf ate due to dilution (CDM 1981). High flows were found to be associated with higher levels of total suspended solids, turbidity, total metals, nitrate, ammonia nitrogen, COD, and coliform bacteria (CDM 1981). Cold vinter water temperatures were found to be associated with decreased levels of sulf ate, phosphorus, nitrogen, su spended solids, and coliform bacteria (CDM 1981). A summary of water quality monitoring data f rom the Missouri River near the Callaway Plant is given in Table 3.1. E All of the water quality parameters analyzed by CDM at the Callawny Plant were similar to the data reported for the Cooper Nuclear Plant (Missouri RM 532.5); most parameters were within the ranges reported for the Cooper Plant (Todd 1980, pp.36-40).

I 3-8 3.3 River Ecology This section discusses the historical data concerning primary productivity, zooplankton, habitat formers, macroinvertebrates, fish and other wildlife. 3.3.1 Prima ry Productivity Phytoplankton are microscopic, photosynthetic algae that are capable of rapid reproduction. It is their ability to t rasf orm radiant solar energy into protoplasm that places the phytoplankton and periphyton (the attached algal form) at the bottom of the food chain. Phytoplankton of the lower Missouri River characteristically occur in low densities and are dominated numerically by diatoms (Berner 1951; Damann 1951; Williams 1966; Stern and Stern 1972; Union Electric Company 1974; University of Missouri-Rolla 1974). The paucity of phytoplankton in the Missouri River is caused by excessive turbidity, high current velocity, and the lack of adjoining lentic (lake-like) waters (Berner 1951) . The harsh conditions of the Missouri River are illustrated by their ef fects on plankton populations entering f rom tributary rivers. Damann (1951) reports that plankters entering the Missouri River f rom tributaries did not multiply. A reduction in tributary phytoplankton populations after entering the Missouri River was also noted by Ballentine, et al. (1970). Berner (1951) had earlier suggested that, in the absence of backwater areas, plankton production was autogenic, with little contribu tion f rom tribu taries. Ballentine, et al. (1970) su pported 1 I'
3-9 the suggestions of others that the tussouri River phytoplankton community originates in lentic waters. , Crowth of rooted aquatic macrophytes and periphycon is limited in the Missouri River because of high turbidity, shif ting substrates, and water level fluctuations. For this reason, phytoplankton populations contribute most of the primary production in the lower Missouri River. Algae are generally considered to be the base (primary producers) of aquatic food web, although in many rivers (such as the Missouri), allochthonous organic natter may be the main energy s ou rc e , i Centric diatoms were the most abundant phytoplankters in the bussouri River near the Callaway Plant (Camp Dresser and McKee, Inc. (CDM) 1981, pp. 2-9) . Stephanodiscus astrea, Microsphina potamos and Cyclotella atomus were the three most abundant and persistent centric species collected f rom the Missouri River (CDM 1981, pp. 2-9) . All three are eutrophic species commonly found in turbid, lotic systems (Lowe 1974, pp. 86, 188 and 296; Taylor, et al. 19 80, p. 2 7) . Two pennate diatoms, Frag 11 aria capucina and F crotonensis, were the dominant species in May 1981 when river flow and turbidity were at maximum observed levels (CDM 1981, pp. 2-9). Both of these species are associated with eutrophic water and F. capucina, the most abundant species, is a tychoplanktonic diatom that was probably flushed out of tributaries by the increased volume of flow (Lowe 1974, pp. 135 and 139).
l 3 - 10 l l The colonial green algae, Dictyosophaerium pulchellum, was prevalent during the late summer and early fall (CDM 1981, pp. 2-9) in ' the Missouri River near the Callaway Plant. Species of the flagella ted chrysophyte, Ochromonas, were most abundant during January and February (CDM 1981, pp. 2-9) . The phytoplankton community of the Missouri River is generally tolerant of cutrophic conditions and heavy organic loading with occasional exceptions derived from relatively unpolluted tribu tary sources (CDM 1981, pp. 2-9) . E The phytoplankton species collected during the Camp, Dresser & McKee study in the Missouri River near the Callaway Plant (CDM 1981, pp. 2-9) were similar to those reported in previous studies (Union Electric Company 1974, Table 2.3.2-1; Table 2-1). Analysis of variance and Student-Neuman-Keuls multiple range tests were run on density, evenness and total phytoplankton abundance as well as the densities of selected major algae groups and taxa (CDM 1981, pp. 2-11). The results of these statistical comparisons support the hypothesis that the phytoplankton of the Missouri River near the Callaway Plant were not spatially patchy, but rather were reasonably homogeneous (CDM 1981, pp. 2-11) . 3.3.2 Zooplankton Zooplankton are microscopic animals that obtain their nutrition by consuming other zooplankton, primary producers (phytoplankton and bacteria) and detritus. Like phytoplankton, zooplankton are important food items for larger aquatic organisms such as larval fish. Because of the flowing water environment, many I I
3 - 11 zooplankton found in rivers are primarily littoral or epibenthic rather than truly planktonic. Typical riverine zooplankton organisms l include protozoans, rotifiers, cladocerans and copepods (Hynes 1970,
- p. 99).
l The zooplankton community of the Missouri River near the Callaway Plant was comprised of 68 taxa, which included 38 Rotifera, 18 Cladocera, 16 Copepoda and one Tardigrada (CDM 1981, pp. 3-6). R airers constitued 84.5 percent of the total zooplankton density while cladocerans, copepods, and tardigrads represented 2.4, 13.1 and less than 0.1 percent, respectively. The only zooplanktera which represented 5 percent or more of the annual mean total zooplankton density were the rotifers Brachionus angularis, B. calyciflorus, B. quadridentatus, and Keratella sp. Copepod nauplii also comprised 7.7 percent of the total composite. This type of zooplankton community was to be expected since rotifers commonly dominate in large rivers (Berner 1951, p. 6; Hynes 1970, p. 99; and University of Missouri-Rolla 1974, p. 463) and Brachionus and Keratella are among the t ru ly planktonic rotifer taxa which nearly always dominate large river zooplankton (Williams 1966, p. 88; Hynes 1970, p. 99). Mean total zooplankton density for all locations for all sampling dates was 14 organisms / liter, which is low for a large midwestern river. This was not unusual since the paucity of zooplankton in the Misscari River has been well documented (Berner 1951, p. 4; Hynes 1970, p. 98; University of Missouri-Rolla 1974, p. 560; and Repsys 1979, p. 58) . Monthly mean zooplankton density was variable but was generally highest from late spring through summer and
3 - 12 i lowest in winter. The seasonal distribution of the five dominant taxa I followed a similar pattern, which indicated that most pulses in total zooplankton densities were related to a pulse in one or more of the dominant taxa. This seasonal distribution of zooplankton in the hiissouri River was typical for large midwestern rivers. Zooplankton populations in the Fitssissippi, Ohio and Illinois Rivers were fnund to be minimal in vinter and increased in abundance f rom spring through summer (University of Missouri-Rolla 1974, p. 467 and pp. 504-508). The results of the Camp, Dresser McKee study (CDM 1981) were very similar to previous zooplankton studies conducted on the Fiissouri River near the Callaway Plant (Union Electric Company 1974, pp. 21-23; 1975, pp. 16 and 19; and 1976, pp. 33-36). In each of the previous studies rotif ers dominated the zooplankton community, and maximum densities (50-70 organisms / liter) usually occurred in late summer when flow and turbidity were low and diatom abundance was high. tiinimum densities occurred in winter months and were usually less than 10 organisms / liter. 3.3.3 Habitat Formers Habitat formers are plants or animals characterized by a relatively sessile life sts' which function as 1) a living or formerly living substrate for the attachment of epibiota; 2) a food source for shellfish, invertebrates and fish; and 3) sites for spawning, nursery, and cover for shellfish, invertebrates and fish. Organisms that may qualify as habitat formers are attached algae, f reshwater sponges, freshwater hydra, bryozoans and rooted i I
3 - 13 " vegetation, in the opinion of the University of Missouri-Rolla (University of Missouri-Rolla 1974, p. 553), there is no true periphyton in the lower Missouri River during flood years. They f ound that structure rocks and pilings showed no growth, because of frequent I abrupt vater level fluctuations, scouring, covering of structure I surf aces by transported sediments, and low levels of light l penetration. They surmised that their periphyton measurements were 1 for potential periphyton growth under optimum conditions which occur rarely, if at all, in the lower Missouri River (University of Mi ssou ri-Rolla 19 74, pp. 553-554) . Rooted aquatic vegetation is usually f our.d in slow moving or standing wa ters. Pa st studies (Union Electric Company 19 74, p. 24, CDM 1981, p. 7-7) stated that no vascular hydrophytes were observed in the Missouri River near the Callaway site. Berner (1947) also reported a complete absence of rooted aquatic plants in the channels, chutes, and backwaters of the Missouri River. He attributed their absence to turbidity, water level fluctuations, and the instability of the fine river substrates. 3.3.4 Ma c roinve r t ebra te s Macroinvertebrates (benthos) are the group of aquatic organisms that inhabit bottom sediments and consist of the la rval stages of many types of aquatic insects, worms (oligocha e t e s) , clams (pelecypods), snails (gastropods) and a variety of other invertebrate animals. Many benthic organisms are predators on other aquatic b macroinvertebrates as well as fish larvae, while others utilize I
3 - 14 detritus, algae or other material. They serve as an important sou rce of food for many types of fish. One hundred benthic macroinvertebrate taxa distributed among 72 genera and 32 families were identified from 144 Ponar grab samples collected at four locations in the Missouri River near the Callaway Plant (CDM 1981, pp. 4-7) . Oligochaeta and Chironomidae comprised the majority of the benthos and were represented by 20 and 33 taxa, respectively. 011gochaeta was composed of 9 species of Naididae and 11 species of Tubificidae. Other aquatie insects comprised 23 genera I within 21 families. Turbellaria represented a significant portion of the benthos at two locations. Other miscellaneous taxa collected were isopods, amphipods, sphaerid clams, and the asiatic clam (Corbicula manilensis). I There are few published accounts of the Missouri River benthos in the immediate vicinity of the Callaway Plant and, until the study by Berner (1951), there had been no published or unpublished data concerning the benthic organisms of the Missouri River (University of Kissouri-Rolla 1974, p. 477) . Berner collected Petersen dredge samples f rom the lower Missouri River at 11 sites from the river mouth to the Iowa state line between April and November 1945. Only 750 benthic organisms were f ound in a total of 130 samples for an estimated density of approximately 29 organisms /m2 . In decreasing order of abundance, chironomids represented 35%, oligochaetes 20%, and Trichoptera 16%. The extremely low productivity (estimated as 0.4 pounds of benthos per acre) of the sampled habitats were attributed to high turbidity caused by high current velocity, shif ting substrates, I
3 - 15 ~ siltation, fluctuating water levels, and the absence of aquatic vegetation (Berner 1951, p. 10). The University of Missouri-Rolla conducted a baseline study of l the Missouri River in 1973 (University of Missouri-Rolla, 1974). Five locations (from RM 132.5 near Bonnot's Mill to RM 101.4 near Gasconade) were established near the preser.t site of the Callaway Plant. The mean number of benthic organisms reported f rom these locations was 173 individuals /m2 . These samples were composed of 011gochaeta (87%), Ephemeroptera (6%), Chironomidae (4%) and Trichoptera (1%). The study ascribed the paucity of benthos to channelization, high turbidity, swif t currents and shif ting substrates (University of Missouri-kolla, 1974, pp 554, 560). Recent studies of the Missouri River adjacent to the Callaway Plant have reached similar conclusions regarding the benthos of the Missouri River, exclusive of dike and revetment habicats (Union Electric Company 1974, 1975, 1976). Mean densities ranged from 486 to 2 1,320 organisms /m and mean biomass values ranged from 827 to 2,483 mg/m2 . In each_ investigation, Oligochaeta (mostly Tubificidae) represented more than 75 percent of the total ~oenthos. Chironomidae were the second most abundant taxa, followed by Ephemeroptera and Trichoptera. Channeliza tion, floods, swift currents, high turbidity F and shif ting substrates were found to be the major factors contributing to low species diversities, abundance, and bioma ss (Union Electric Company 1974, p. 28; 1975 p 34; and 1976, p 88).
3 - 16 I ! A total of 127 taxa were identified in the drifting I I macroinvertebrate samples collected from June 1980 through May 1981 from the Missouri near the Callaway Plant (CD!! 1981, p. 423) . The number of taxa per location ranged from a low of 85 to a high of 103. Mean spatial densities ranged f rom 97 organisms /100m3 to 156 8 organisms /100m . llydropsyche orris was the most abundant species collected at each location. Mean annual densities of this organism ranged from 18 to 38 individuals /100m8 . Of the 127 drif ting macroinvertebrate taxa collected, 88 were aquatic insects. Chironomidae was the most diverse family of aquatic insects present, comprising 35 taxa. Mayflies wera the second most diverse group of insects, representing 14 taxa distributed among 7 families. A third diverse group of organisms were the Polycheeta. Thirteen species of naiad worms, 7 species of tubtficid worms, and I unidentified species of enchaetraeid worm were collected. The highest number of taxa (57) was collected in March, and the lowest number of taxa (26)- was f ound in July. There is very little data available concerning the macroinvertebrate drif t assemblage of the lower Missouri River (CDM 1981, pp. 4-39). Berner (1951) calculated that about 64 million drifting organisms, weighing abr 200 kilograms, passed under the Boonville, Missouri River bridge in a 24 hour period in 1946 (Berner 19 51, p. 8) . Of 381 drifting organisms collected in the lower Missouri River between May and November 1945, Chironomidae comprised 48%, Plecoptera 9%, Ephemeroptera 12% and Trichoptera 12% (Berner 1951, p. 8). An intensive drift survey conducted near Fort Calhoun I
l 3 - 17 i Station (RM 646) from 1973 through 1977 f ound Hydropsychidae (37%) Chironomidae (24%) and Ephemeroptera (14%) the most abundant groups ) I (Carter 1977, p.158) . Union Electric Company (1975) collected drift samples near the Callaway Plant in June and September 1974. Species composition in drift samples varied greatly from that observed in grab sampics collected during the same investigation. The most abundant organisms collected were stenonema sp., Hexagenia sp. , Chaoborus sp. and Polypedilum sp. All of these organisms, except Hexagenia sp., were common or abundant in similar seasonal samples, llowever, drift densities (about 5 organisms /100m8 ) were one-tenth of the ainimum drif t density of 50 organisms /100m 3f ound in the CDM (1981) investigation. 3.3.5 Fi sh The abundance and diversity of fish in the Callaway Plant area of the Hissouri River are determined by the physical habitats present, water quality, and the populations of organisms in other portions of the food web. Many larval fish species feed on plankton as f ry, but feed on aquatic insects or other fish as adults. Adult fish may act as primary consumers by feeding on phytoplankton; secondary consumers by feeding on zooplankton or benthic organisms; or tertiary consumers by feeding strictly on other species of fish. Funk and Robinson (1974) did an extensive literature review and found that 63 species of fish have becn collected from the Missouri River. They did not include species that were collected only
3 - 18 in the mouth of tributary streams and were believed to be more characteristic of the tributary than the main river. They summarized their literature study by stating that the fish populatten of the river has become dominated by a few species adapted to survival in the swift, turbid stream and that diversity of the population has declined as habitat has become less varied and diverse. Spectacularly large specimens of lake sturgeon and paddlefish have not been taken for many years. The lake sturgeon has virtually disappeared, the paddlefish has declined drastically and the blue catfish now makes up only a small part of the total population. Crapp ., sunfish, black bass and saugers, which once made up a considerable portion of the population, now are seldom taken. The exotic carp increased dramatically soon after introduction, apparently at the expense of the native buf faloes and carpsuckers, and has remained dominant, The flathead catfish may be declining in the river at present; the channel catfish is the only major species besides the carp which seems to be increasing in I abundance. These changes have paralleled the physical changes in the river and, while proof of a cause and ef fect relationship is lacking, the circumstantial evidence of a direct relationship between decreased diversity in the habitat and decreased diversity in the fish population is very strong. A study of the fish populations in the Missouri River near the Callaway Plant was conducted from June 1980 through May 1981 by Camp, ( Dresser 6 McKee (1981). A total of 2950 fish comprising 43 taxa was collected in the Missouri River by all sampling methods during this study. Electroshocking in the Missouri River was by far the most i I
3 - 19 ef f ective sampling method for both total numbers and diversity. Fifty seven percent of the total catch (1670 fish) and 32 species were collected by this method. Ca tch-per-ef f ort ranged f rom a low of 0.09 fish /minu te in August to a high of 3.39 fish / minute during Fuy, e . rage catch-per-ef f ort for the year was 0.95 fish / minute. Although catch-per-ef f ort wa s generally low, the rates are typical of tne lower Missouri River. In 1979, catch-per-ef f ort at Cooper Nuclear Station (RM 532.5) averaged approximately 0.6 fish / minute (King 1980, p. 110). During previous studies for the Callaway Plant, high water greatly hampered electroshocking effectiveness and the method was discontinued (Union Electric Company 1975, p. 24). Seining accounted for a total of 603 fish comprising 15 taxa, many of which were not readily collected by other sampling methods (CDM 1981, pp. 5-9). Two species, the emerald shiner (Notropis atherinoides) and the red shiner (Ji, lutrensis), comprised 72 percent of the specimens from seine collections. Gill netting accounted for 13 percent of the total catch (387 fish), comprising 18 species'. This gear type was almost singly selective for one species, the shovelnose sturgeon (Scaphithynchus platorynchus) . Trap netting was the Icast effective technique employed during the Camp, Dresser & McKee study (1981).' Less than 10 percent of the total catch (290 fish) was taken by this method. Trap nets captured 23 species but appeared to be most selective for catfish species and freshwater drum (Aplodinotus g ru nnien s) . Ten fish species were collected during the Camp. Dresser 6 McKee study (1981) which were not reported f rom previous river
3 - 20 I collections near the Callaway Plant (Union Electric Company 1976, pp. I
'3-76). The most notable of these were the rainbow smelt (Osmerus
/
mordax), an exotic species, and the sicklefin chub (Hybopsis meeki), presently listed as rare in Missouri (Nordstrom, g al.1977; p. 28) . Other uncommon species collected were blue sucker (Cveleptus elongatus), stonecat (Noturus flavus) and walleye (gizostedion vitreum). Although species composition has differed from previous studies near the Callaway Plant, major components of the river's fi a community have remained similar (CDM 1981, pp. 5-21). Differences in species composition generally did not include species associated with big river systems but were primarily limited to species in other faunal classifications. Despite rigorous sampling eff orts in the Missouri River near Callaway, fish population densities were very low, primarily due to the harsh environment of the lower river caused by high turbidity, strong currents and the pat. city of spawning and/or preferred backwater areas (CDM 1981, pp. 5-41). 5 3.3.6 Wildlife Resident vertebrate wildlife populations in the vicinity of the Callaway intake area are limited since much of the adjacent lands are used for agricultural row crops and the river is channelized. The forest margins along the river banks, backwaters behind dikes, sandbars, forested islands and pastures are the major areas for resident vertebrate wildlife. Beaver, turkey , raccoon, rabbit and small duck populations (mallards, wood ducks, etc.) have been observed near the Callaway intake. During low river elevations Canada geese have used the large sandbar downstream of the intake on the south s'.de I
3 - 21 s of the river. Fall and spring bird utigrants have been observed in the vicinity of the intake. Resting areas for these migrating birds l- include dike fields during normal or low water elevations, bac kwa t e r areas formed in fields and lowlands during and af ter flooding, or old side channels of the river. The immediate vicinity of intake and discharge does not contain vegetation or habitat which would attract or hold large numbers of migratory waterfowl or resident vertebrate vildlife. B I E B I
4-1 4.0 Entrainment Study 4.1 Objectives I L Objectives of the entrainment study were to document the density, composition and spatial and temporal distribution of icthyoplankton in the Missouri River in the vicinity of the Callaway Plant. These data were used to calculate estimates of actual- and worst-case entrair. ment by the plant, i Entrainment estimates are expressed as percent entrainment relative to icthyoplankton transport. Percent entrainment estimates help demoastrate that best available technology (BAT) was used to design the intake to minimize adverse enviroumental impact to the i aquatic ecosystem. 4.2 Materials and Methode 1 4.2.1 Collection Site Locations and Descriptions Three parallel zones which encompassed the entire width of the river between RM 116 and the '.ntake (RM 115.4) (Figure 4.1) were sampled weekly f rom April 1, 1984 through September 23, 1984. All three zones shavn in Figure 4.1 were bounded on the upstream (west) end by an imagtnary line perpendicular to the shore at the 116 mile marker and on the downstream end by an in.aginary line perpendicular to the shore at the downstream edge of the intake (RM 115.4). Zones were designated as B2, B1 and B3 because these were the designations used in preoperational studies (CDM 1981, 1982). Throughout the remainder i

4-3 g_ of the document these same zones will be referred to as north (B2), middle (BI) and south (B3) zones. l The north zone (B2 in Figure 4.1) is the zone closent to the j j intake and will be considered representative of the " zone of influence". Samples were collected along a path parallel to the bank
- i and the face of the intake. The downstream portion of each haul put the boat as close to the face of the intake as possible without
- colliding (2-3 meters).
4 The middle zone (B1 in Figure 4.1) was the geometric center of the river on the sample day. The path for this haul was parallel and equidistant between the paths for the other two zones. The south zone (B3 in Figure 4.1) was parallel to the south shore and just off the ends of the wing dikes under normal flows. During high flow conditions, such as those experienced of ten in 1984, this zone shif ted south so that hauls were taken over the tops of the dikes. The three zones were situated to divide the eurface of the ) river into thirds on a sampling day and the south and middle zones i shif ted somewhat because of this. The north zone was consistently the same relative to the intake and north shore regardless of stage. i I 4.2.2 Sampling Methods f Paired 0.5 meter diameter conical nets with No. 0 "Nitex" mesh (0.570 micron openings) were mounted on f rames to simultaneously L sample on each side of a 18 foot boat. Each net was fitted inside 4 t e, ., . ,-m ..

4-4 I vith a calibrated model 2030 General Oceanics flown.ater. The starboard net had an identical flowmeter on the outside. Inside meters were used to calculate the volume of water sampled and readings were compared with the outside meter to check f or net clogging or back-flushing. Nets had a 27 in, deep cylindrical section of Nitex sewn in at I the mouth to reduce back-flow. Nets were made by Ernest Case Company and cod end collection buckets were WILDC0 47-F64 1-liter plastic with 583 micron steel mesh screen. Each of the two net hoops were velded to 10 f oot long box steel arms with holes for pivot pins spaced at 6" intervals. Pivot pins held each net on the end of a midship box steel cross bar so that each net could be pivoted in and out of the water at the beginning and end of a collection (haul). Nets were deployed and retrieved simultaneously on both sides of the boat and all meters were read between hauls. Hauls were made with the boat moving downstream, with the engine at about 1100 rpm, between the 116 mile marker and the downstream corner of the intake at E river mile 115.4. Three consecutive hauls were made in each of the 3 cones on each sample day for a total of 18 discrete samples per day and 4o8 total samples during the 26 week sample period. Af ter each haul, nets were carefully rinsed f rom the outside of the net by swishing in the river and use of a pump with hose attached before being brought aboard. Net contents were rinsed with squirt bottles into a flat pan and then placed in a discretely labeled I
j 4-5 16 oz, polethylene sample jar. Each jar was turked with a discrete sample (ID) number and a label was placed inside the jar. This label included ID number, plant, date, zone, side of boat (L or R), replicate number (in that zone for that day, 1-3), number of jars used for that sample, and the collector's name. Samples were preserved in I the field with 10% formaldehyde. I Field data was recorded on data sheets which included the I following information for each sample collected: 1D, date, plant, zone, net number, side / replicate, flow meter ID numbe.r, start and finish flowmeter readings, number of jars used for the sample, start time, stop time, river stage, water temperature, outside flowmeter ID numbers and start and finish readings, and any remarks. Samples were stataed, rinsed and all visible icthyoplankton were separated from detritus at the laboratory in St., Louis. Rose Bengal was used to stain eb;;* and larvae and an illuminated magnifier was used to make them more easilf visible. Processing sheets were filled out in the lab f or each sample and included the following: sample ID, number of jars, start date, completion date, initials of sorter, different taxon sorted and number of each, number of eggs, and general comments. Taxa that were distinctly different from a sample were sorted into separate petri dishes or jars, marked with the sample ID and designation (name or number) and preserved for further identification and measurement in a 75% alcohol, 20% water and 5% glycerine solution.
4-6 I All larvae and eggs were identified to the lowest possible taxon and measured to the nearest 0.1 mm using a dissecting microscope fitted with an ocular micrometer and polarizing filters. Specimens were placed into the following life stages: egg, prolarva (yolk sac), larva (yolk absorbed but fin compliments incomplete), and juvenile (full compliment of fin arrays). All specimens were kept for future reference. Specimens were identified with the aid of keys by May ar.d Gasaway 1967; Taber 1969; Hogue, g al.1976; and Auer 1982. Bench processing eheets were filled out with the following information ID, jar number, species code, lif e stage, size, sorter, identifier, confirmer, disposition of specimen, completion date, and remarks. 4.2.3 Entrainment Rate C+;eulations
'ntraitunent rates were calculated by the following method.
The volume of water sampled on each haul in each net was calculated by converting flow meter counts to distance traveled and multiplying by the area of the net mouth opening. Percent entrainment was calculated using a slight modification I of the methods in Mathematical Methods to Evaluate Entrainment of Aquatic Organisms by Power Plants (U.S. Fish and Wildlife Service 1977) where: E I I

To calculate entrainment estimates. Gasconade River discharges I at Jerome, Missouri were subtracted f rom liermann discharges for that day. The stage discharge rating curve for Callaway based on these adjusted discharges and actual stage measurements at the intake are presented in Figure 4.2. The discharge estimates for liermann and Callaway for the entrainment sampling period of 1984 are compared in Figure 4. 3. 4.3 Re su lt s The Callaway icthyoplankton sampling program was conducted weekly from April 2, 1984 through September 24, 1984. The sampling period included the entire period in which fish eggs and larvae were likely to exist. Eggs and larvae were first collected on May 1 and none were collected a!ter September 10. Density values are expressed as number per 100 m3 . The mean quantity of water filtered on a given day was 1666 m3 (range 1028 m3 to 2155 m 3
) with a total of 43314 m3 I sampled during the entire 26 vecks. Each of the 468 individual sampSs filtered a mean quantity of 92.6 m3 with a range of 33 m to 161 m3 .

i 4 - 11 i 4.3.1 Species Composition Abundance and Densities A total of 3541 fish and 195 eggs were sampled representing at , least 26 taxa (Table 4.1) . Four taxa comprised over 85% of the total taxa sampled. These predominant taxa were: f reshwater drum (54.12%), gizzard shad (15.44%), carp (8.78%), and other minnows (6.69%). No specimens of rare, threatened, or endangered species listed for l Missouri Waters (Missouri Department of Conservation 1977), or included on the U.S. Fish and Wildlife Service List of Endangered or e Threatened Wildlife (U.S. Dept. of the Interior 1975) were found at the callaway Plant. Because some specimens were identified only to the genus or family level or were unidentified, the possibility does ' exist that sane rare species were included in the collection. The lack of rare fish (with the exception of the sicklefin chub) in adult , fish samples in this-study and previous studies in the same area makes the presence of rare eggs or larvae unlikely. Number collected, mean--density per 100 m and percent frequency- - of' occurrence in the 244 samples that contained icthyoplankton are I shown in Table 4.2. ' I . l Total specimen frequencies for all taxon combined by date with l zones compared are shown in Figure 4.4. L .

4 - 15 I The entire raw data base for the study is presented in Appendi,4 B. Specimen f requencien by date with life stages indicated are presented in Figure 4.5. A total of 2022 f reshwater drum were co'lected with a mean density of 22.7/100 m3 (Table 4.2) and a range of 0.6 to 157 per 100 3
- m. Most of the drum sampled were juveniles (Figure 4.15) which would probably not be as susceptibic to ent rainment as larvac. For the purposes of estimates, all drum sampled were considered as "entrainable".
Drum first appeared in the samples on June 4 and were not sampled af ter August 27. Drum densitico peaked in mid-July at an average density of 128/100 m . Drum appeared in 90 of the 244 samples that contained icthyoplankton for a percent occurrence of 37%. Drum densities compared between zones show the south zone and north zone (zone of influence) both having the highest mean densities on a date. Middle zone densities peaked at almost half of the other zone densities (Figure 4.6). A total of 577 (Table 4.1) gizzard shad were collected with a mean density of 5.43/100 m3 (Table 4.2) and a range of 0.6 to 24 per 3 100 m . Shad were collected in 113 of the 244 samples that contained icthyoplanktoi, for a 45 percent occurrence. Gizzard shad were collected f rom May 14 through August 6 (Figu re 4. 7) . Mean zone densities peaked at 14/100 m3 in the south I zone during late June. There were lesser peaks in the north zone (zone of influence) during mid-June and late June as well as early

4 - 22 I July. liiddle zone 'snuities were consistently lower with the only I peak in mid-July (ligure 4.7). Carp were the third most abundant taxon with a total of 328 and 3 a mean density of 4.6/100 m with a range of 0.7 to 25.7 per 100 m . Most of the fish identified as carp were juveniles since the minnow family is difficult to identify to species when the specimens are la rvae . These juvenile carp were also considered "entrainable" even though some were probably capable of avoiding the intake. Carp were collected in 79 of the 244 sampics when larvae or eggs were present f or a 32% occurrence. Carp were sampled from thy 22 throut,h August 6 and peaked during July (Figure 4.8). Mean zone densities were highest during mid-July in the middle I zone. An earlier but lower peak was seen in the first part of July in the north zone and a smaller peak in the south rone simultaneously with the middle zone peak (Figure 4.8). Minnoi species that were identified only to f amily made up 6.7 percent of the total taxon with a total of 250 specimens (Table 4.1). The mean density of minnow species (other than those identified as carp) was 1.9/100 m with a sample range of 0.6 to 21 per 100 m . l Unidentified minnow species were collected in 83 of the 244 sampics that contained icthyoplankton for a 34% occurrence. Unidentified minnows were collected from thy 22 through September 10 with peaks during late to mid-June (Figure 4.9). I I
J _ 4- 23 inclusion of more than one species makes these peaks difficult to interpret. ~ Zone mean densities by date peaked in the north zone on June 8
~
at almout 14/100 m3 with a lesser peak in the south zone at the same time of 6.4/100 m . 'the peak in the middle zone was later in early July and slightly higher than the south zone peak (Figure 4.9). 1 The fifth most abundant taxon was freshwater drum eggs with a total of 140 specimenu (Table 4.1) and a mean density of 1.9/100 m (Table 4.2) with a sample range of 0.6 to 6 per 100 m .3Drum eggs were collected in 74 of the 244 sampics that contained icthyoplankton for a 30% occurrence. Drum eggs were collected from K1y 14 through Sept ember 10 and peaked in density'during mid-June and again in mid-August (Figure 4.10). Zone densities were highest in the north zone during mid-June and peaked again at a much Icser density in mid-August (Figu re 4.10) . Unidentified sucker species ranked sixth in abundance with a total of 118 specimens at a mean density of 1.9/100 m and a sample range of 0.7 t o 8 per 100 m .3 Catastomids are dif ficult to identify as adults due to errors in fact interpretation and omiasion in classification (11ubbs, 1930) and lack of interspecific dif ferences in meristic features such as scale and fin ray counts (Robins and Raincy. 1956). Because larval fish identification relies on meristic differences, suckers were identified only to family in this study.
4 - 24 I 1.iterature exists to discern buffaloes from redhorses but there are I contradictions. Unidentified suckers were collected May 7 through September 4 and occurred in 72 of 244 samples for a 29% occurrence. Zone mean densitics peaked in the south zone during mid-July in I the north zone in early July and in the middle zone in mid-August (Figure 4.11). Again, as with unidentified minnows, the probable combination of several species complicates and lengthens the density and occurrence plots. Goldeye were the seventh most abundent taxon with a total of 105 (Table 4.1) specimens and a mean density of 5.3/100 m3 (Table 4.2) with a sample range of 0.8 to 19 per 100 m3 . Goldeye were collected in only 22 of 244 ichtyoplankton containing samples for a 9% occurrence. Goldeye were collected from May 22 through June 4 or for only 3 weeks which accounts for the relatively high density '. Figure 4.12). Goldeye mean density peaked in the north tone on thy 22 at over 14/100 m 3 and were below 2/100 3m in the other two zones for the entire period of occurrence (Figure 4.12). Unidentified eggs made up the eighth most abundant taxon with 3 55 specimens and a mean density of 1.7/100 m with a sample range of
- 0. 7 t o 6 per 100 m . Unidentified eggs were collected in 41 samples that contained icthyoplankton for a 17% occurrence.

Mean zone dennities were highest in the middle zone during late hay but were collected more i often and at greater densities in the other two zones. The bouth rone had the greatest average density over the entire sample period followed by the north zone (Figure 4.14)
- The remaining 18 taxa mde up the other 5% of t'

- Thene include unidentified prolarvac (23), larvae (4), atid juveniles (1) (Table 4.1).
Mean zone densitiss of all taxa combined are presented in Figure 4.14 'Ihe peak of densities in mid-July is largely due to the mny juvenile f reshwater drum that were sampled. 4.3.2 Larva Length Dist ribu t ion Analysis of length distribution of major taxa provide an , indication of spawning period and/or locality (Fig. 4.15-4.20). Length data f or all taxon are presented in Appendix B.2. Mean lengths and ranges of all taxa are presented in Table 4.3. 4.3.3 Entrainment Re su lt s Estima ted tocan entrainn.ent rates are presented in several ways. The mean of rates calculated from each sample that contained icthyoplankton is presented by taxon and totaled in Table 4.4 This table also includes the means for density, entrainment, and percent entrainment of a transport rate.

Mean entrainment rates for each taxon did not exceed 0.65 fish /second (Table 4.4) . The range of species entrainment rates calculated f rom individual samples ranged from 0.021 to 4.03 fish /second (freshwater drum). I Mean transport rates for each taxon ranged from 34 fish /second to 786 fish /second. Individual sample ranges were f rom 13.5 fish /second to 5366 fish /second (f reshwater drum) . I Mean percent entrainment tates for each taxon ranged from a low of 0.04 percent to a high of 0.14 percent. The individual taxon plots show the same pattern of low early summer percent entrainment with highest levels in late summer. I Mean percent entrainment for each of the 8 most abundant taxon by date are presented in Figure 4.21 through 4.28. Mean percent _ entrainment for each date with all taxon combined are presented in Figure 4.29. Froshwater drum and etinnow species show the greatest range of percent entrainment values with means by date (Figure 4.21 and 4.24) just as with the means of all samples (Table 4.4) . Gizzard shad and carp show virtually identical patterns and ranges ,(Figure 4.22 and 4.23).

4 - 48 l Goldeye showed the most limited range of percent entrainment I rates of any of the top 8 taxon (Figure 4.27) while unidentified eggs showed a similar pattern to freshwater drum eggs (Figure 4.28). I When all taxon are combined to plot mean percent entrainment, the same increase through the season is shown with the greatest change during aid to late July (Figure 4.29). 4.4 Discu s sion The Callaway intake shows best available technology to minimize adverse environmental impact in both design and operation. The entrainment estimates made in this study are, if anything, overstated because of the assumption that all icthyoplankton sampled in the north zone an entrained. Estimates made are probably higher then they would actually be I for the following reasons:
- 1. Estimates are based on three pumps operating. With the cancellation of Unit 2, all three pumps have not been used nor will they be used in the future. Actual entrainment would probably be two-thirds of the estimates.
I
- 2. The intake face is parallel to a consistently strong current with bar racks that work as louvres perpendicular to the current. This design serves to deflect passive larvae drif ting into the screens just as it does to deflect debris.
I I I
'I 4 - 49
- 3. The deep opening of the intake withdrawal reduces entrainment of buoyant larvae and eggs.
- 4. A large majority of the icthyoplankton sampled were juveniles (Figure. 4.5) . Juveniles have a full fin compliment and are thus capable of deliberate swimming and avoiding the intake.
- 5. Some of the eggs and larvae that pass through the screens are probably returned to the river alive through the f ree discharge valve (see operational description, p. 2-10).
The icthyoplankton sampling program appears to have encompassed the entire period of icthyoplankton occurrence throughout the year since samples collected in April and late September contained no eggs or larvae. 5 Samples collected were representative of what was entrained. The average volume sampled on a day was over 23% of the total intake withdrawal rate during the 45 minutes of total sample time. With all three pumps running the intake would withdraw 7156 m8 of water during a 45 minute period. The 18 samples collected on a date took approximately 45 minutes total with an average total volume of 1666 m' or 23% of the plant withdrawal. 4.4.1 Taxon Abundance and Densities The relative abundance of principal taxa at Callaway agrees with previous studies done by CDM (1982) in the same area. GLzza rd shad and f reshwa ter drum dominated the 1981 samples collected by CDM I I
4 - 50 I (Table 4.5) just as with this study. Other studies done on the middle Missourt by King (1977,1980) and Harrow and Schlesinger (1981) found drum most abundant followed by catostomids and carp (King 1977, p. 47, and 1980, p. 121; Harrow and Schlesinger 1981, p. 298) . Peak densities of all larvae occurred during June and J* '.y in this study and in othera on the Missouri (King 1977, p. 47. Harrow and Schlesinger 1981, p. 294, and CDM 1982, p. 102). There is some disagreement between the present study and that done by CDM during 1980-81 but the mandated monthly sampling program required by the Nuclear Regulatory Commission was probably inadequate to detect peaks of abundance. The dominant taxa collected in this study are typical of the I lower Missouri River (King 1980, p. 121; Harrow and Schlesinger 1981,
- p. 298) and generally paralleled adult fish populations in the i
immediate vicinity (See Section 6, this report). Low densities of taxon such as Morone sp. , sunfish, crappie, sauger, paddlefish, etc. are attributed to these species neither being common in the Missouri River nor having larvae that are generally subject to drift. Game species did not contribute appreciably to the assemblage even though some, such as juvenile and adult catfish were relatively common in the vicinity. The clumped schooling behavior of larval catfishes in backwater areas may have kept them from being part of the larval drif t. Extremely low densities of catfish were collected by CDM (1982) at Callaway (0.1% of total) and also by Union Electric at Rush Island on the Mississippi River (1 fisn, 0.1% of total) (Union I I

I, 4 - 52 ) Electric 1979b , p. 4-10) . Freshwater drum peak densities peaked with I!! carp densities as in the King, and Harrow and Schlesinger studies but the 1981 CDM study showed a peak that was largely gizzard shad. When density of larvae were compared with water temperature I (Figure 4.30) and discharge (Figure 4.3) no correlation (least squares) was found f or either. The July peak in abundance of all/ taxa, particularly juvenile drum and carp, can probably be attributed to the rapid fall in discharge from a stage where the river was out of its banks. It is probable that these juveniles were occupying flooded habitat such as riparian vegetation and the sudden fall in river stage flushed them out into the river. It is likely that this was a behavioral response of juvenile fish that are capable of deliberate swimming as much as a physical displacement of them. Previous falls in discharge seen in Figure 4.3 did not re st.lt in the flush of fish probably because these juveniles were not present c1(se enough upstream at that time to show up in samples. E If juveniles are excluded, larvae peaked in mid to late June just as in the CDM study (1982, p. 101), the King study (1977, p. 47) and the study done by Harrow and Schlesinger (1981, p. 257). A June peak density was also seen in the Mississippi River in the vicinity of the Rush Island Plant. Temporal distribution of larvae and eggs agrees fairly well with other studies with larvae appearing in May and peaking in June and July (King, 1977, CDM 1981, p. 47; Harrow and Schlesinger 1981, p. 257). Peaks in this study were related to freshwater drum just as I I

4 - 54 during the 1978 Union Electric study on the Mississippi River (1979b,
- p. 4-98) . Spatial ccraparisons made in this study show, with the exception of carp (Figure 4.8) and unidentified eggs (Figure 4.13),
the middle zone with the lowest overall densities (Figure 4.14). The north and south zones were generally equivalent in densities with the north zone being lighter on same dates during mid-May and mid-June (Figure 4.14) . The north zone includes the channel where the swif test and deepest water is found. Higher densities in this zone agree with the previous studies at Callaway (CDM 1982, p. 103). Harrow and Schlesinger (1981 p. 294) reported highest densities at maximum river depth. King f ound, however, that highest densities were along the filling bank in high flow years and along the cutting bank in low flow years (1980, p.123) . The north zone at Callaway is along the cutting I bank , bu t 1984 would be considered a high flow year so there is disagrement between these two studies. The occasions when there were significant dif ferences between mean zone densities in the north and south zones were only 4 of the 26 dates (Figure 4.14) . These dates were May 22, June 11 and 16, and July 9,1984 (Figure 4.14) . The paired sample emparisons for the north zone show the close correlation in icthyoplankton densities (Figure 4.31-4.33) from one side of the boat to the other. In spite of slight differences in volumes sampled f rcm one side to the other (4.34-4.36) the densities per 100 m8 are very close for organisms that display a random patchy distribution like larval fish.

4 - 61 4.4.2 1,engt h Dist ribu tion The dearth of prolarvae that were sampled (Figure 4.5) inlicate that no tajor spawning or nursery areas are immediately upstream of the intake. The average hatching size of f reshwater drum is 3.2mm (Swedberg and Walberg, 1970). This size was collected during the study, but not in very grea t numbers (Fig. 4.15) . This indicates either that newly hatched drum nre not susceptibic to drift or that the drum larvae caught were hatched at some distance upstream. The latter is more likely due to the pelagic spawning habits of drum. Gizzard shad hatching sizes range f rom 3.3 to 3.5eun (Auer 1982,
- p. 70), and some of these sizes were collected (Fig. 4.16). Just as with drum, the majority of the shad sampled vere juveniles which indicates hatching upstream.
Carp hatching sizes range from 3.0 to 3.5mm (Auer 1982, p. 194), and none this small were sampled. Unidentified minnows were sampled as small as 4.lmm (Table 4.3), some of which may have been carp. The demersal adhesive eggs of carp are less likely to drif t than are f reshwater drum eggs. Unidentified minnow species sampled were mostly larvae and prolarvae (Fig. 4.16) . This is largely due to the fact that prolarvae and larvae are more dif ficult to identify than are juveniles, so unidentifiable specittens tended to be small.
4 - 62 Unidentified suckers collected ranged f rom 2.5 to 31.0mm in length. 11atching sizes f or suckers range f rom 5 to 10mm (Auer 1982, gl E '
- p. 345). tbny of the suckers collected were prolarvac (Fig. 4.19),
which indicates spawning ocr.urred closer upstream than for the previously discussed taxon. tbny of these were probably river carpsuckers which are the most common catostomid adjacent to the plant. Goldeye hatch at f rom 7.3 to 7.6mm (Battle and Sprules 1960) which includes sizes captured at Callaway. Most of those sampled were prolarv o (Fig. 4.20) . The goldeye size and duration of occurrence in the sampics indicated those that were sampled hatched nearby and then ) were either not present in larger sizes or not vulnerable to the sampling methods used. . All remaining taxon lengths are presented in Appendix B.2. 1 Overall, the dearth of prolarvae indicates that there are no major 1 spawning or nursery areas immediately upstream of the Callaway intake 4 f or the taxon collected. 4.4.3 Entrainment The entrainment of icthyoplankton through the Callaway Plant will have minimal ef fects on the fish populations of the Missouri River. This conclusion is based on the low estimated percentage of larvae entrained of less than 0.2% of those being transported (Ff.g. 4.29). Worst case percent entrainment did not exceed 0.75% (Fig. 4.29). I I
4 - 63 Table 4.4 shws that those taxon sampled in the gtcatest L numbers did not necessarily show the highest percent entrainment estimates. 1his can be attributed to several f actors including a higher density for that taxon in the north zone on a sampling day than in the other two zones. Those species that have missing values for entrainment estimates in Table 4.4 are those that were not sampled in the north j zone (zone of influence) and were thus not included in calculation of l the density that was entrained f rom that zone. These taxon were sampled in extremely low numbers in any of the zones (a maximum of 4), but would not be considered less entrainable than similar sizes of species that were sampled in the north zone. The trend of increasing entrainment percentages f rom July through August is exaggerated on the expanded scales of the individual 1 taxon figures (Fig. 4.21-4.28). The trend, however, is still present in the less sensitive scale of all the taxon combined percent entrainment figure (Fig. 4.29). This is due to increasing densities of specimens (particularly juvenilea) late in the season and decreasing discharges. These two factors resulted in an increase in percentage entrainment estimates even though many of the fish sampled were juveniles (Fig. 4.4) and probably less susceptible to entraincient i than eggs or larvae. The worst case percentage entrainment estin.ates show a
- decreasing trend through the season (Fig. 4.29) probably because of l i decreasing densities and using a constant discharge for this l l
t
4 - 64 I c alcula t ion. The worst case discharge used in the calculations probably is indeed a worst case discharge as it is the record low flow f or the months when fish eggs and larvae are present from 1929 through 1980. 4.4.4 Summa ry and Conclusions The Callaway entrainment study sampling period encompassed the entire season of larvae and egg presence in the Missouri River during 1984. The most abundant taxon sampled were freshwater drum, gizzard shad, carp, minnow species, freshwater drum eggs, cuckers, goldeye and unidentified eggs. No rare, threatened, or endangered species were I identified. Icthroplankton were first collected on May 1,1984, and were not collected after September 10, 1984. The north zone, the zone of influence, generally had the highest egg and larvae densities.. The middle zone generally had the lowest densities, while the south zone was intermediate. Mean percent entrainment rates for dominant taxon show the saae increasing trend throughout the season due to the same factors previously mentioned (Fig. 4.21-4.28). Freshwater drum and freshwater drum eggs shcued the widest rangen (Fig. 4.21 and 4.25) due to wide ranging densities. Gizzard shad and carp showed almost identical patterns due to being sampled in almost identical densities simultaneously even though gizzard shad adults are more abundant near the intake (see Field I I
4 - 65
- Tisheries section of this report) and they have a higher reproductive s
potential. The goldeye percentage entrainment pattern (Fig. 4.27) is very limited because goldeye were only collected on three occasions. Mean percentage entrainment estimates peaked at less than 0.151 ~ using actual discharge estimates on sampling days and did not exceed 0.75% using record low flows for April-September 1929-1980. The low percent entrainment estimates are tne result of low percentage of water withdrawal by the plant and relatively low densities of icthyoplankton. I These low entrainment percentages indeed reflect that best available technology was used in intake design and operation. This best available technology results in minimum adverse impacts to the aquatic environment due to entrainment. I I I I I I I k I
5-1 5.0 Impincement study i 5.1 Introduction Impingement is the physical blocking of large organisms by a barrier, generally some type of screen system in a cooling water intake and involves the collision of an organism with a portion of the structure (U.S. EPA 1977, p. 18). I Fish are the primary organisms subject to impingement in the Missouri River. Gizzard shsd (Dorosoma cepedianum) and freshwater drum (Aplodinotus grunniens) are the principal species of fish typically impinged at water intake structures on the Missouri River. This predominance in impingement collecticns may reflect these species' physiological condition, their overall abundance or, for shad, their susceptibility to impingement. Other species of fish usually take up a small percentage of the total number of fish impinged in the Missouri luver (Equitable Environmental Health 1976). Life stages of fish most susceptible to impingement are young-of-the-year fish and one year old fish. Adult fish are sometimes susceptible during spwning or migration runs, periods of weakened condition (poet spawning periods, parasitic or bacterial infections) Or perieda of cold water temperatures. I susceptibility of juvenile and adult fish depends on a number of factors including fish swimming ability; attraction or avoidance behavior; river currents, velocities and direction of flow relative to the intake structure; intake velocities, volume and alignment relative I l I
5-2 to the tiver; nearby habitats; and presence of various intake devices to reduce impingement. The impacts are highly site-specific. Therefore, adequate physical and biological data are needed to determine impingement effects. This section examines potential effects on adult fish in the I vicinity of the Qillaway Plant caused by impingement by the intake structure. 5.2 Objectives An impingement study was initiated to quantify the effects of I the Callaway intake structure on the various species and life stages of fish during commercial operation of the Callaway plant. The study I, involved inonitoring of fish impingement on the intake screens and recording of pump flow rates to ascertain the impingement rate. This progra.n extended frcnn February 1785 through January 1986. It provided inf ormation on species composition, impingement rates, numbers and weights per species, and length-f requency distributions of impinged fish. 5.3 Ma terials and Methods The 1985-86 impingement study employed methods and procedures recommended by U.S. EPA, Region VII. TM Callaway impingement study plan was approved by the Missouri Department of Natural Resources. I I I I.
5-3 5.3,1 Sample Collection _ impingement samples were collected f rom the screen wash by means of a collection basket system which was located on the downstream sic'c of the intake structure. During sampling periods, manually operated gates in the screen wash troughs diverted the screen backwash flow into a pipe which emptied directly into a collection basket. The collection basket was constructed of 1/2" square screen mesh identical to that used on the plant's traveling screens. The basket theref ore retained all caterial st rained and washed f rom the screens. Impingement samples were taken by diverting the screen wash flow to the collection basket f or a twenty-f our hour period. Sample collection was usually conducted from 8:00 a.m. to 8:00 a.m. During this period the screens were operated in their normal modes. The screens were washed before the 24-hour sampling period began and immediately bef ore the sampling period ended. This assured that only fish impinged during the 24-hour tests were collected, plant personnel maintained operating logs that recorded the number of intake water pumps in operation during each sampling period. Total plant withdrawal f or each sampling period was developed f rom this operating data. At the end of the 24-hour collection period, diversion of the screen wash flow was stopped and the collection was processed. This procedure was repeated once each week on a random-day basis during the one year testing period. I
5-4 5.3.2 Sample Processing and Analysis Fish were separated from any trash or debris which collected in the impingement basket during sampling. The samples were processed in the field except during the winter season, when frozen samples were returned to the St. Louis laboratory for analysis. Fish were sorted and identified to species. Those species I occurring in large numbers were sorted into length ranges of 0-100 mm, t 101-150 mm, and then in 50 mm increments thereafter. Fish were weighed and measured to the nearest gram and millimeter, respectively. When five or more fish of the same species were in the same length range, five were weighed and measured while the remainder were included only in the total count for the length range. Identifications were made with taxonomic keys published by Pflieger (1975) and Clay (1975). Identifications were made in the field except difficult to identify specimens, which were returned to the St. Louis laboratory for identification. The scales used for weighing were Accuweigh, Universal Dial Scales, model M-800, 800 grams x 1 gram, and model M-1250, 12 kilograms x 50 grams. Fish were measured for total length on a 100 centimeter measuring board divided into millimeter increments. Scales and measuring boards were calibrated and calibration records were filed for quality assurance. I I I
5-5 l 5.3.3 sample Docceentation
!engths, weights, numberr, and species of fish collected were recorded on field work sheets. Other data recorded on the work sheet were the date, the plant code, the code for each specico, and any remarks concerning the condition of the fish (e.g. alive, scale loss, disea sed) .
Data recorded by plant personnel included the date, the times the collection period began and ended, river temperature at the intake, mode of screen operation, number of Antake pumps operating, river elevation, distharge temperature, duration of operation of electric boilers for deicing, and water temperature rise caused by the electric deicing boilers. 5.3.4 Data compilation and computations Automatic data processing was used to compile the sample data and to perform computations. The field work sheets were designed to facilitete direct computer coding of data. The coded data was verified for accuracy after coding. The verified data from each sample collection was then combined to form a complete impinge:nent data set. Computerized data compilations were prepared in various forms. For each impingement sample , the compilations included: the fish's common and scientific names, the total of each species collected and totals per 10 million gallons (MC) of intake water sampled, the total weight of each species and the total weights per 10 MG of intake water
$-6 sc.mpl e d . Compilations were also prepared for all species combined f or each impingement sample . Theoc included: the total number of fish collected and total per 10 MG of intake water sampled, the total weight of fish collected and the total weight per 10 MC of intake water sampled. I Compilations for all impingement collections combined were prepared detailing each species collected by common r. ate, scientific name, total numbers, relative abundance, total weight, and relative weight. Also determined were the total number and weight of all species sampled during the study period.
The monthly average numbet 2nd monthly average weight per 10 I million gallons of intake water pumped were calculated for euch species comprising at least 4% of the total collected, and also for all less dominant species combined. A monthly total number and a monthly to,41 weight per 10 million gallons of intake pump water f or all species combined were also calculated. Monthly length-frequency distributions were calculated f or each species collected in total numbers of ten or more. Monthly and annual estimates of the number, weight, relative I abundance and the relative weight of impinged fish were calculated. These estimates were made two different ways. One set of estimates was based on total intake pump water flow and impingement totals for the month. This method estimated the annual impingement rate based on average monthly impingement rates. The second set was estimated based on daily impingement ra t e s. I I o
i 1 5-7 i l j Data analysis required computations of various impingement f rates and weights per unit flow. Impingement sample number s and 1I
- weights were grouped first by species and then by total numbers of l fish collected. Each of these values were then divided by the intake t
l pump water flow (in units of 10 million gallons) during the collection 1 period. This yicided impingement rates (number /10 million gallons) and weights (g/10 million gallons) for individual sampics both by
- ha species and for all species combined.
i A similar procedure was followed to develop estimates of i monthly and annual impingement rates and weights. In these
- computations the first step was to sum the numbero and weights of impinged fish sampled during a month. The monthly sums were then divided by the volume of intake pump water flow sampled during the month to yield a monthly average impingement rate (number /10 million 1
gallons) and weight (g/10 million gallons). These monthly averages were then multiplied by the total monthly circulating water flow to l i 1 ig derive the estimated monthly impingement rate and weight. These l 4 3 I q computations were done f or each individual species and the total j numbe.r of all fish impinged. j f This process was repeated using the number of days sampled and the number of days in a month rather than the amount of intake pump flow sampled and total monthly intake pump water flow. Total estimated annual impingement rates and weights were obtained by summing monthly rates and weights in both cases. I I I
5-8 5.4 Results This section presents the impingement sample collection data and the estimates of toonthly annual impingement rates and weights. 5.4.1 Satopling Result s Impingement sampling results are presented for each sampling period and on a monthly basis. Results are presented for water flow satapled, species composition,19,1 ingement rates, impingement weights, and length ranges of impinged fish. 5.4.1.1 Water Withdrawal The amount and percentage of the water withdrawal flow sampled during the iropingement collections is tabulated in Table 5.1 on a monthly and annual basis. The amount of water withdrawal sampled represents 14.13% of the total water withdrawn by the callaway plant during the study period. 5.4.1.2 species composition l Thirteen species of fish representing nine families and only 301 specimens were collected during the 51 sample collections, Table 5.2. Gizzard shad (275. 91.4%) and f reshwater drum (12, 4.0%) l l accounted for 95.4% of the total specimens. Other species that were collected in numbers of greater than one were channel catfish (Ictalurus punctatus) (3,1.0%) and blue catfish (Ictalurus furcatus) (2, 0.7%). I I

Shortnose gar (Lepisosteus pla t os t omu s) (2.7%) and blue catfish (3.4%) made up 6.1% of the total weight. The other seven species accounted for 1.5% of the total weight collected. Threatened, endangered, or rare fish species were not collected during impingeraent sampling (U.S. Dept. of Interior 1975, Missouri Department of Conservation 1977). The results of the individual sample collections are presented in Appendix C.l. 5.4.1.3 Impingement Rates Impingement rates f or individual samples are presented in Appendix C.I. Impingement rates during the study ranged from 0 fish per 10 million gallons (31 impingement tests) to 39.7 fish per 10 million gallons on Tebruary 15, 1985. Monthly rates varied from 0.0 fish per 10 million gallons during four months to 15.6 fish per 10 million gallons in February 1985, as summarized in Table 5.3. During the taximum impingement month, gizzatd shad accounted f or 15.5 of 15.6 fish per 10 million gallons. Gizzard shad was the dominant species impinged except during Pay and August when other species were impinged at the rate of 0.1 fish per 10 million gallons. I I l _ _ mm

5 - 13 Frcan the middle of tiny through the middle of November 1985 (28 impingetrent tests), there were no fish collected during the impingement tests except on August 30 when one flathead catfish was e collected. Thus, the majority of impingement occurred from late fail througl. .he spring. 5.4.1.4 Impingement Weights Impingement weights f or individ'Ja1 collections are presented in Appendix C.1. Impingement weights for individual collections ranged from 0 grams per 10 million gallons for 31 of the impingement tests to 882.4 grams per 10 million gallons on ^pril 13, 1985. Monthly average impingement weights ranged f rom 0 grams per 10 million gallons during four tuonths to 303.0 grams per 10 million gallons in April 1985 as sutamarized in Table 5.3. April 1985 was the month of highest impingement by weight. This was caused by the collection of a smallmouth buffalo that weighed 3550 grams. This specimen appeared to have been dead greater than 24 hours, and therefore may have been dead prior to impingement. I Gir:ard shad's highest impingement by weight was in February 1985 when 115.9 grams per 10 million gallons were impinged. 5.4.1.5 Length Ranges of Impinged Fish Monthly length-frequency distributions were compiled for those fish specit-s contributing more than 10 specimens to the impingement collectivns during the study. The percentage of fish in each length
$ - 14 range was computed for each month. 1,ength ranges were compiled for girzard shad and freshwater drum and are presented in Appendix C.2.
The length-f requency distributions for gizzard shad indicated I. that 98% of the 275 specimens collected were less than 150 can in length. This length corresponds approximately to age class one. 1 Seven of the twelve freshwater drum were 150 nrn or less which also corresponds approximately to age class one. All of the freshwater drum collected were less than 300 cru so they were approximately age four or less. 5.4.2 Projected Result s Monthly and annual projected impingement results are presented for total numbers of all species and for individual species. The projections based on the number of fish impinged per 10 million gall-ans resulted in higher impingement rates than the rates per day and are presented in Table 5.4 Estimates based on rates per day are included in Appendix C.3. 5.4.2.1 Projected Total Annual Impingement The total annual impingemect for all species of fish was projected to be 2410 fish per year with a total weight of 59,525 grams. This projection of total annual impingement is viewed as a conservative estimate of the annual impingement that would be expected during the life of the Callaway plant. This is because the plant operated at a higher than expected capacity factor and normal river conditions occurred during the impingement study. The total annual I I

5 - 16 impingerven t projections are presented in Table 5.4 and the projected monthly totals are presented in Appendix C.4 5.4.2.2 Projected Species composition E The two species of fish that were predominant in the actual impingement data remained predominant in the impingement projections. Gizzard shad (2235, 92.7%) and freshwater drum (83, 3.4%) accounted for 96.1% of the individuals projected to be impinged annually. Only three other fish species were projected to be impinged in numbers of 10 or more. They were channel catfish (18, 0.7%), blue catfish (12, 0.5%), and walleye (10, 0.4%). 5.4.2.3 projected Impingement Weights Gizzard shad (17,994 g, 30.2%), smallmouth buf f alo (26.545 g, 44.6%), and f reshwater drum (6303 g, 10.6%) accounted for 85.4% of the projected total annual impingement weight of 59,525 grams. Shortnose gar (1326 g, 2.2%), river carpsucker (4827 g, 8.1%), and blue catfish (1653 g, 2.8%) accounted for 13.1% of the projected total annual weight of impinged fish. The seven other fish species accounted for only 1.5% or approximately 887 g of the projected total annual weight of impinged fish. 5.5 Discussion This section will examine the significance of the Callaway intake impingement and the factors which influence impingement. The intake vill impinge fish whenever there is water withdrawal. Whether this impingement causes adverse environmental impact must be evaluated I
5 - 17 5 in respect to the results of the impingement study conducted for the Callaway intake structure, and with those results compared to the fish populations of the Missouri River. 5.5.1 significance of Ittpingemeni The significance of the plant's impingement will be addressed through discussion of threatened and/or endangered species, preeminant species, other species, size class of fish impinged and the field fisheries data. The magnitude of any adverse environmental impact f rom impingement by the Callaway plant intake is difficult to quantitatively determine f rom the data. However, the significance of the impingement losses and thr3 adverse environmental impact, if any, can be assessed from the relative magnitude. 5.5.1.1 Threatened or Endangered Fish No fish of threatened or endangered status listed for Plssouri waters (Mo. Dept. of Con. 1977) or included on the U.S. Fish and Wildlif e Service List of Endangered or Threatened Wildlife (U.S. Dept. of Interior 1975) were collected during the impingement study at the Callaway Plant. 5.5.1.2 Predominant species The impingement samples and the projected estimates indLe ated the predominance of two fish species, gizzard shad and freshwater d rum. Projected results showed that 2235 gizzard shad and 83 f reshwater drum could be expected to be impinged aanually by the Callaway Plant's intake structure. These species are numerically
abundant in the Missouri River. Shad are an important forage species l and their populatione have demonstrated resiliency and impressive compensatory potential. Of the gizzard shad impinged, 98% were age class one or less. Young gizzard shad naturally suf fer a high mortality rate according to Bodola (1966) who estimated that of 100.000 age I fishe6, only 5,534 age II fishes and 435 age III su rvive . The annual impinget ent of freshwater drum was 83 specimens weighing 6,303 grams (13.9 pounds) . All the freshwater drum impinged wore less than 300 nun in length and 58% were age class one or less. These impingement rates of gizzard shad and freshwater drum by the Callaway intake are considered an insignificant adverse impact when taking into account the abundance of these species in the Missouri River, the age class of impinged fish, natural mortality and compensatory potential . Thus, there is no impact of consequence to the fish populations in the vicinity of the Callaway intake structure. 5.5.1.3 other Species Eleven other species of fish were impinged during the impingement tests. Table 5.2. None of these species are considered unique and all are common components of fish collections made from the Missouri River. The projected results showed that each of these species are estimated to be impinged at eighteen specimens or less per year. These eleveu other fish species are not unique to the Missouri River, and therefore, hold ne special significance by their presence at Callaway. It is thus unlikely that the annual impingement of 18 specimens or less of any species of fish that is not threatened or endangered would have a significant adverse environmental impact. I I'
5 - 19 \ 5.5.1.4 Age Cla ss of,_ Fish Impinged The fish which were impinged showed in almost all cases that the majority of specimens were immature or age class one. Table 5.2, Appendix C.1, Appendix C.2. Tnis fact la important in several respects. First, natural mortality and natural compensatory potential make these losses less significant. The second is that the older and more mature age classes are not being impinged. The field fisheries data have shown older age classes of fish to be present; therefore, same other mechanism such as intake design, location, capacity or construction must be the reason for their absence in impingement sample s. 5.5.1.5 Field Fisheries Data The field fisheries data f rom electrofishing illustrate the abundance of gizzard shad and f reshwater drum in the vicinity of the Callaway Plant intake structure. Gizzard shad was the most abundant fish collected by electrofishing, making up 26.9% of the fish collected by this method. Freshwater drum ranked second in relative abundance making up 24.4% of the fish collected by electrofishing. Freshwater drum's relative abundance of 18.1% was the second highest abundance of the various species collected by seining. The setning and electrofishing data exemplify the predominance of the freshwater drum population, and the electrofishing data exemplify the predominance of the gizzard shad population in the Kissouri River. Feeding, spawning, and nursery areas for fish are limited in the area of the intake structure. Fish involvement with the intake
E 5 - 20 basically entails fish migrating around the structure. The low I' impingement rates indicate that the intake structure was located and ' designed to minimize impingement since the field fisheries study has shown that fish do reside in the area. 5.5.2 Intake Design, Constru,etion capacity and Location The extremely low projected annual impingement rates of 2,410 fish with a total veight of 59,525 grams (131.2 pounds) can be attributed to the design, construction, capacity and location of the Callaway Plant intake structure. The Callaway Plant was designed with a natural draf t cooling tower system rather than with a once through cooling system. This minimizes water usage to make-up water to replenish the cooling system and thus has reduced water usage more than 90% as compared to a once through cooling system. This water usage reduction minimizes water withdrawal and consequently impingement. To further minimize impingement the intake was located so it protrudes into the river's main channel and withdrews water from the bottom of the swif t main channel of the Missouri River where few fish can inhabit. The size of the intake portion of the structure was increased beyond the required design in order to reduce the velocities of intake water through the screens which also minimizes impingement. The maximum velocity at the screens during the minimum navigational flow of 35,000 cf a vill be about 0.3 f t/s. This velocity will allow the majority of fish from becoming impinged unless they are lethargic, diseased, or in a stressed condition. Also, to lessen entrapment and minimize impingement, fish gates are located between the screenwells. This allows a fish that has entered the intake through the bar racks I

- 5.5.3 Summary and Conclusions A total of 1,933,932,000 gallons or 14.13% of the total flow '
withdrawn by the Callaway intake f rom February 1985 through January 1986 was sampled for impinget.ent impact. The sampling indicated a predatainance of two species, gizzard shad (91.4%) and freshwater drum (4. 0":) . Thirteen species of fish representing nine families sud 301 apecimens welghing 8.4 kilograms were collected during the 51 -
.ngement sample collections.
The sampling data and water withdrawal d. .s ira combined to project the total annual 1mpingement rates (nute - 10 million gallons of water withdrawn) and weights (grams per 10 million gallons of water withdrawn). The total annual impingement was estimated at 2410 fish weighing 59.5 kilograms (131.2 pounds) . Gizzard shad (2235, 92.7%) and freshwater drum (83, 3.4%) accounted for 96.1% of the individuals projected to be impinged annually. No other species were projected to be impinged in numbers greater than 18. l
E 5 - 22 The length ranges of the fish collected during the impingement sampling indicated a strong predominance of immature fish. The intake is not impinging mature adults in quantities large enough to produce a sigrificant adverse impact. This is especially true for gizzard shad, where more than 98% of those individuals impinged were in age class one or below. The impingement of immature fish in relatively low numbers as predicted at Callaway may be of f set by natural compensatory potential since immature fish are subject to large natural losses bef ore reaching maturity. Threatened, endangered, or rare fish species were not collected during the impingement study. Impingement of gizzard shad and f reshwater drum by the Callaway I intake are considered an insignificant adverse impact when considering the abundance of these species in the Missouri River, the age class of impinged fish, natural mortality and compensatory potential. The other eleven smcies of fish were each impinged in very low numbers (18 specimens or less) and are species common +o the Missouri River. It is thus highly unlikely that impingement ot these fish would have a significant adverse environmental impact. The fielo fisheries data shows the abundance of gizzard shad and f reshwater drum in the vicinity of the Callaway Plant intake s t ru c tu re . Feeding, spawning, and nursery areas for fish are limited in the area of the intake structure. The low impingement rates indicate that the intake structure was located and designed to I I
7 .. 5 - 23 minimize impingement since the field fisheries study has shown that fish do reside in the area. 3
- The extremely low projected annual impingement rates of 2410 fish with a total weight of 59.5 kilograms (131.2 pounds) can be attributed to the design, construction, capacity, and location of the Callaway intake structure. These low projected impingement rates for the Callaway intake structure reflect the use of the bect technology available for minimizing impingement by a cooling water intake struc tu re. The magnitude of the . impact by the Callawaj intake is difficult to accurately determine. However, the relative significance of the intake's impingement can be shown. The impingement study has
-shown that-the impingement impact is not significant enough to adversely affect the fish populations of the Missourt River.

6-1 6.0 Field Fisheries Study 6.1 Objectives The objectives of the field fisheries study were to provide inf ormation on the aquatic ecosystem of the Missouri River in the vicinity of the Callaway Plant intake. These data were used to help intet pret data and support conclusions of the entrainment and impingement studies. Population dynamics (such as species composition and relative, spatial and temporal abundance) of adult and juvenile fish were compared with thoce same parameters for the larval, adult, and juvenile fish collected during entrainment and impingement studies. 6.2 Ma terials and Methods I Adult and juvenile fish were sampled monthly by electrcfishing at five shoreline sites upstreas, at, downstream, and across the river f rom the Callaway intake (Figure 6.1). Shoreline seining was conducted when and where possible within these sites to sample small adults and juveniles that are not as effectively collected by electrofishing. I 6.2.1 Electrofishing Methods Electrofishing was done with a 20 f oot aluminum boat equipped with a gasoline powered 5000 watt generator. A Cor f elt WP-15 control box was used 40 rectify and control outpu ts. Alternating currents of 220 volts were adjusted for maximum amperage of up to 14 amps, depending on existing water conditions.

6-3 All fish sampled were identified to species, veighed to the nearest gram and measured for total length to the nearert millimeter. Abundant species such as gizzard shad and freshwater drum were subsampled by grouping them into 50mm length groups and recording lengths and weights for 5 individuals within a group while the rest were counted. Identifications were made with the help of taxonomic keys by Clay (1975), Pflieger (1975), Smith (1979), and Trautman i (1981). All fish collected on the south shore (sites 4 and 5) were released immediately af ter being weighed and measured. Those fish that were large enough were tagged with a Floy FD-68-BC anchor tag. Some fish collected on the north shore (sites 1, 2 and 3) were kept for radiological analysis as part of the Callaway radiological monitoring program mandated by the Nuclear Regulatory Commission. This program was often conducted concurrectly with adu'.t fish sampling carried out for this study. Specifications require collection of these samples from the north shore. Any fish from sites 1, 2 or 3 that were not needed for radiological analysis were released. Fish that were large enough were tagged with the same type of Floy tags as those on the south shore. The fish tags are labeled with discrete numbers and inf ormation on where to return the tag when a tagged fish is caught by a commercial or sport fisherman. Information from tag returns and fish recaptured by UE personnel provides valuable information on growth, condition and movements of fish in big rivers. Union Electric has tagging programs instituted near several other power plants on the Osage, Mississippi and Missouri Rivers. Results and discussion of the I
6-4 Callaway tagging program will not be included in this report. Data from tag returns and recaptures from all plants are still being analyzed. All data were kept discrete as to collection, date and gear type. Water temperature and Missouri Rivei discharge at Hermann were recorded for each collection day. A zone was considered to be sampled , when one complate pass had been made down the shoreline and around any discernable off shore structure or habitat that could be effectively shocked (generally less than six feet deep). This offshore structure might include the tip of a ving dike, a notch in a dike, a sand bar or a ledge. Habitat shocked r.pht icelude pilings, snags, drif t niles, l or submerged trees. Total snocking time within a zone was recorded so l that catch-per-unit-effort (CPUE) calculations could be made. Il l 1 6.2.2 Seining l Monthly shoreline seining was conducted in areas with suitable l depths and firm substrates. A 30 foot by 6 foot, 1/4" mesh bag seine was used. Hauls were made downstream, keeping the net perpendicular I: to the bank. Distance moved down the bank was recorded. All fish collected during a seine haul were preserved with formalin and labeled for processing back at the lab. Distance seined, site location, depths, substrates and other pertinent p rameters were recorded. 6.2.3 Col]- 'on Sity Locations and Descriptions I Five co!1 action sites were sampled during the field fisheries study. Figure 6.1 illustrates the collecting site locations. The ; l l I I
6-5 collection sites' locations corresponded to some of the collection sites sampled during the Callaway preoperational studies (Camp, Dresser & McKee 1981, 1982). Collection sites 1, 2, and 3 were near shore sites located on the north shore of the Missouri River. Site 1 is located from dike 122.2 (River mile 116.2) downstream to the upstream side of the Callaway intake. The shcreline of site 1 is riprapped with a narrow band of mature trees (cottonwood, willow, silver maple) lining the bank area. Substrates at this site were usually riprap. The main channel of the river is located just off-shore from site 1. The water depth of site 1 dror ' sharply from the narrow band of shallow water along the straight riprapped shoreline, i Site 2 is located from the downstream side of intake downstream to dike I?!.58 and encompasses the immediate discharge area. A retaining wall for a barge unloading area and eddy currents are characteristic of this site which Fas a mud and fine sand substrate. The shoreline is steep and water depths of 15 feet or greater exist just off-shore. I Site 3 extends from the downstream side of dike 121.58 to dike 121.0. This site has dike fields whic'.i provide quiet water areas during low flows. When river elevations breach the dikes, flows become turbulent and swif t. The bank area is lined with mature trees of willow and silver maple. Subst.ates are varied and include fine sand, silt, and mud. The collecting area for this site depends on river elevation. During low flows the riprapped portions of the dike fields must be sampled because access to inside the dike fields is I.

6-6 limited by low water levels. Median flows allow access to the dike fields and' large areas for collection. During above median flows only the shoreline is capable of being sampled. I Sites 4 and 5 were near shore sites located on the south shore of the Missouri River. Site 4 encompasses the area of three L-head dikes from dike 122.1 downstream to approximately river mile 115.4. The substrates at this site were sand, silt and mud. When river elevations are low, large areas of quiescent water is present. But when the dikes are breached, turbulent and swif t flows exist. Water depths are variable within the dike fields. Deep water is present within the eddy portions of the dike fields, and shallow water exists along the banks and upstream side of the dikes. The banks are lined with trees with mature specimens on the high banks and new growth on the low banks. Site 5 begins directly across tt.e river from the intake structure at the start of a tree line anc ends at the upstream side of dike 121.2. Water depths are shallow because this site is a sand flat and extends into a chute behind an island. A small short dike is present just upstream of the chute. Vegetation on the banks is similar to what exists at site 4. Snags and stranded drift characterize the habitat of the chute. Water flow is swif t and the substrates are sand, silt and mud. 6.3 Re sult s - 6.3.1 Species Composition The collection by all fish sampling methodologies represented 2805 specimens comprising 14 families and 41 species.

6 - 20 carp were dominant species during the spring and suramer seasons. Longnose gar was a dominant species in the summer and shorthead redhorse in the winter. In the summer and fall seasons, river carpsucker was a dominant species in the electrofishing collections. Seasonal species composition for each electrofishing collection site are presented in Appendix D.3. Appendix D.4 provides data concerning each species collected in electrofishing collections for each site and all sites by showing the total number collected, mean total length, length range, mean weight, weight range, percent total biomass collected, and percent occurrence in the collections. Seining collection data showing numbers and relative abundance for each species during the study are presented in Table 6.lL Seining produced chub, shiner and minnow species that were not present in the electrofishinr, collections, thus providing further documentation of the fish populations in the vicinity of the Callaway intake structure. Sampling by seining collected a total of 881 specimens representing 8 families and 17 species. The dominant species f rom the seining collections were channel catfish (63.5% relative abundance), f reshwater drum (18.1%) and river carpsucker (9.1%) . The specimens of these species were all young of the year and this shows the high fecundity and compensatory potential of these species. Seining was scheduled to be conducted monthly but because of I inclement weather and high river elevations, sampling was only accomplished on July 24, 1985. Electrofishing was not conducted in December 1985 because of adverse river conditions. I I

Dept. of Con. 1977), or included on the U.S. Fish and Wildlife Service List of Endangered and Threatened Wildlife (U.S. Dept. of Interior 1975) were collected during the study. Two sicklefin chubs (11ybopsis meeki) were collected by seining on the south shore during the study. The sicklefin chub is considered rare by the state of Missouri. 6.3.2 Pflieger Faunal Composition Analyets I Pflieger faunal composition analysis is a method of characterizing and analyzing the fish populations according to the habitat requirements of the various species. Faunal composition may be based on the number of species or the number of specimens within each faunal grou p. The Pflieger faunal composition percentages for all electrofishing collections monthly, seasonally and for the year by number of species and by number of specimens are presented in Tables 6.13 and 6.14, respectively. For all sites 50.0% of the species were wide ranging, 29.4% Big River, 5.9% Ozark and Prairie, and 2.9% each fell into Lowland, Ozark-Lowland and Ozark-Prairic faunal groups. The faunal composition percentage by number of specimens at all sites for I the year were 52.7% Big River, 41.8% Wide Ranging, and 4.5% Prairie. All other faunal groups combined made up 1.1% of the specimens. Appendix D.5 contains the Pflieger faunal composition percentages by the number of species and by the number of specimens tor each electrofishing collection site by the month, season, and year.

The length-f requency distributions are in 50 millimeter (mm) increments f or f reshwater drum and gizzard shad, but are in 20 mm increments for other species. These length-f requency distributions provide inf ormation on the size distributions of fish occurring at the collection sites in the vicinity of the Callaway intake structure during the study. 6.3.4 Catch-Per-Unit-Effort Table 6.15 presents catch-per-unit-effort (CPUE) figures for the electrofishing collections. CPUE was calculated as a number of fish per standardized effort (fish per minute sampled) for each collection site and for all sites by month, season and the year. The CPUE ranged from 0.0 CPUE at site 1 and 2 in January 1986 to 6.0 CPUE at site 1 in April 1985. Site 4 CPUE of 0.96 was the lowest catch rate of the five sites during the study. Site 2 had the highest cpl!E (2.41) during the study. The spring season CPUE of 2.27 was the highest seasonal average and the winter season CPUE of 0.51 was the lowest. The CPUE at all sites for the year was 1.36 fish per minute. I

Seasonality may also be examined by consideration of the percentage of total catch for a species that occurred during each season. Table 6.16 presents this information for all species that were collected in numbers of five or more in cicetrofishing sampling. This table shows that seven of the eighteen species were present in all seasons. Seven other species were present during all seasons except the winter. Smallmouth buf f alo and sauger were collected only in the spring and fall. Shorthead redhorse were not collected in the summer and 54.5% of the specimens were sampled in the vinter. The majority of gtzzard shad were collected in the spring (37.57) and fall (46.7%). Goldeye and f reshwater drum were collected in the ;Aghest numbers in the spring, when 62.7% and 60.3% of the specimens were collected, respectively. ::eventy percent of the flathead catfish were collected in the summer. Spring (34.4%) and summe r (54.6%) was when the majority of shortnose bar were collected. whereas longnose gar was collected in the highest numbers in the I summer and fall.

E 6 - 31 I 6.4 Di scussion I 6.4.1 Species Cottposition and Abundance I Threatened or endangered fish species (U.S. Dept. of Interior 1975; Missouri Dept. of Conservation 1977) were not collected during the field fisheries study or previous studies near the Callaway Plant (Union Electric Co. 1974, 1975, 1976; Camp, Dresser & McKee 1981, 1982). Sicklefin chub, a species considered rare by the state of Missouri (Missouri Dept. of Conservation 1977), were e allected during the 1985-86 study and previous studies (Camp, Dresser & JcKee 1981, 1982). The occurrence of the sicklefin chub within the study area was not unexpected relative to the habitat present within the study area. Pflieger (1971, p. 338) reported that the sicklefin chub occurs only in the Missouri River and lower Mississippi River in Missouri, preferring the main channel with substrates of sand and fine gravel. Its abundance increases toward the mouth of the Missouri River. The only fish species collected during the 1985-86 study which had not been sampled during previous studies uns the grass carp (Ctenopharyngodon idella) . Pflieger (1975) states the grass carp is a native of eastern Asia that was brought into this country as ear as 1963 and was introduced into open waters of Arkansas shortly thereafter. The grass carp is reported to be an inhabitant of large riv er s. The larger streams of Missouri, particularly the Mississippi and Missouri, appear to provide suitable habitat (Pflieger 1975). Relative abundance and species composition has varied during the Missouri River field fisheries investigations conducted f or one I
6 - 32 I Callaway Plant. Species composition stayed relatively constant for I the river as a whole, but has fluctuated eccording to sampling methodologies and collection sites. Relative abundance has varied among studies but not beyond what would be expected of fish populations in a dynamic riverine environment. Camp, Dresser 6 McKee (1981) in electrofishing coller . ions f ound gizzard shad (69.8%), f reshwater drum (5.2%), shortnose gar (5.0%), aad ri T carpsucker (4.9%) to be the most abundant species in the river near the Callaway Plant. The following year Camp. Dresser & McKee (1982) in electrofishing collections found freshwater drum (36.5%), gizzard shad (35.5%), river carpsucker (6.6%), and goldeye (6.1%) to be the abundant species. The 1985-86 study found gizzard shad (26.9%), f reshwater drum (24.4%), goldeye (16.7%), shortnose gar (8.5%), and carp (5.9%) to- be the most abundant species. Cizzard shad and f reshwater drum have remained the two predominant species collected during the last three field fisheries studies at Callaway. The dif ferences in relative abundance between studios can be attributable to naturally fluctuating biotic and abiotic conditions. There were 34 species collected by electrofishing during the 1985-86 study and in past studies 28 species (Camp, Dresser & McKee, 1982) I and 31 species (Camp, Dresser & McKee 1981) were collected by this methodology. The species composition has remained stable in the Missouri River near the Callaway Plant. Differences in species numbers between studies is accountable by the occurrence of a few
- minor species being collected during certain studies.
I
B 6 - 33 I Seining ss.mples showed high fecundity and compensatory potential of certain species since 559 channel catfish, 159 f reshwater drum, and 80 river carpsucker were collected on July 24, 1985. Seining samples provided information on the presence of minnow, shiner, and chub species, just as past studies have done (Camp, Dresser 6 McKee 1981, 1982). I 6.4.2 Cotrparison by Pflieger Faunal Conposition Faunal cm. positions of the collections from fisheries studies conducted at the Callaway Plant were compared using Pflieger's classification system. The analysis was based on the number of species since analysis by number of specimens would skew the composition toverd certain f aunal groups because of the dif f erences between studies. Table 6.18 presents the Pflieger faunal composition by the number of species collected during the various studies. The earlier electrofishing studies to the present study conducted in the Missouri River near the Callaway Plant shows that faunal composition has been shif ting from the big river raunal group to the wide ranging faunal group. One reason why this phenomenon may be happening is because of the Army Corps of Engineers dike notching program. Just recently the Corps implemented dike notching to create more diverse fish habitat by eliminating sediment build-up behind certain dike fields. Dike notching has created scour holes, flow behind dike fields during low to medium flows, and habitat diversity. This diversity has created niches where faunal groups other than the big river faunal group can I I

6 - 35 inhabitat within the emin portion of the Missouri River. This shift is beneficial since the big river f aunal group is as abundant but has helped to restore diversity within a river system which has been greatly altered by past channelization and stabilization practices. 6.4.3 Impingment Composition and Abundance 1mpingement samples included utne families and thirteen species, as shown in Table 5.2. Walleye (Stizostedian vitreum) was collected in the impingement studies but was not collected in the 1985-86 field fisheries study. This species has been collected in other studien conducted in the Missouri River near the Callaway Plant (Camp, Dreser
& McKee 1981. 1982). Gizzard shad (91.4%) and f reshwa ter drum (4.0%)
together comprised 95.4% of the relative abundance from the impingement collections. Gizzard shad was the most abundant species in the electrofishing sampling, and f reshwater drum was the second most abundant species. Also, f reshwater drum was the second most abu ndant species in the seining collections. Impingement sampling results indicated that 98% of impinged gizzard shad are one year old or less. The compensatory potential and
~
natural mortality rates (Bodola 1966) of this species suggest that any effect on their populations from impingement would be insignificant. Impingement primarily af fects gizzard shad and freshwater drum, the two dominant species in the electrofishing collections. The field fisheries and impingement studies both confirm the predominance of gizzard shad and freshwater drum in the Missouri River. The other species in impingement samples were less dominant in abundance which
6 - 36 I was consistent with their lower abundance in the field fisheries I study. 6.4.4 Intake Structure Location-Fish Involvemenj - The intake structure's location was selected so its ef fects on the fish populations would be minimal. The intake was located on a I straight rip-rap bank that has the main river channel immediately of f-shore. Water withdrawal eccurs from the depths of the main channel where fish inhabitation is minimal. The intake structure is located where spanning areas are limited and nursery areas are almost non-existent. Fish involvement with the intake basically entails fish migrating around the structure. Major feeding areas do not exist in the area of the intake structure. The impingement study, which was conducted concurrently with the field fisherica study, projected that 2410 fish weighing 59.5 kilograms (131.2 pounds) would be impinged annually. H is extremely low impingement rate lends further credence that the intake structure does not exist in major spawning, nursery, or feeding areas for fish (see sections 4.4.2 and 6.2.3). From the middle of May through the middle of November 1985 (28 impingement tests), there were no fish collectea during the impingement tests except on August 30 when one flathead catfish was collected, he majority of impingement by the intake structure occurred from late fall through the spring. The field fisheries data show that the highest concentration of fish (CPUE) occurs in the spricg and fall around the area of the intake structure. This sculd account for the impingement that occurs in the fall and spring. The I l 3
6 - 37 impingement of fish in the winter by the Callaway intake occurs primarily because of the stressed and lethargic condition of fish during periods of cold water temperature. The construction of the intake structure created a small area downstream of the structure which is more conducive to fish inhabitation than the straight rip-rapped bank which existed before construction. This area is small and limited by the swift and deep main channel which is innediately off-shore. 6.5 Summary and conclusiona The 1985-86 field fisheries study collected a total of 2805 specimens representing 14 f amilies and 46 species by electrofishing and seining. The electrofishing portion of the study surveyed 34 fish species which is comparable to the 31 and 28 species surveyed in previous studies. In electrofishing collections gizzard shad (26.9%), freshwater drum (24.4%), goldeye (16.7%), shc rtnose gar (8.5%) , and carp (5.9%) were the dominant species. Camp Dresser 6 McKee (1981, 1982) also found gizzard shad and freshwater drum to be the two most dominant species in electrofishing collections. Seining sampling collected 881 specimens representing 8 families and 17 species which documented the presence of many species not readily collected by other sampling methodologies. Threatened or endangered fish epecies were not collected during the 1985-86 field fisheries study. The sicklefin chub which is considered rare by the State of Missouri was collected by seining. I
6 - 38 The grass carp was the only species collected which had not been collected during previous studies in the vicinity of the Callaway Plant. Analysis of species composition by Pflieger faunal composition shows that the percentage of vide-ranging species is increasing and the percentage of big river species is decreasing from analysis of past and present studies conducted at Ca llaway . This phenomenon may be occurring because of dike notching by the Army Corps of Engineers. This has increased habitat diversity and possibly has increased fish diversity within the channelized Missouri River. Impingement primarily af fects gizzard shad and f reshwater drum, the two dominant species in the electrofishing collections. The field fisheries and impingement both confirm the predominance of gizzard shad and freshwater drum in the Missouri River. The other species in impingement samples were less dominant in abundance which was consistent with their lower abundance in the field fisheries study. Feeding, spawning, and nursery areas for fish are limited in the area of the intake structure. Fish involvement with the intake E basically entails fish m.igrating around the structure. The low impingement rates indicate that the intake structure was located and designed to minimize impingement since the field fisheries study has shown that fish do reside in the area of intake.
