1.0 INTRODUCTION

TVA is required by its National. Pollutant Discharge Elimination System (NPDES) Permit for Sequeyah Nuclear Plant (SON) to conduct and report annually on operational nonradiological monitoring to evaluate potential effe. cts of SQN on Chickamauga Reservoir. The monitoring program was initially designed to identify major changes in water quality and biological communities of Chickamauga Reservoir resulting from opera-tion of SQN. Results of monitoring conducted in 1980-1984 (reported.in j

TVA, 1982; 1983; 1984; and 1985) identified few significant changes in Chickamauga Reservoir considered to be related to operation of SQN.

Based on absence of plant-induced effects and fulfillment of the minimum period required by the NPDES permit, some components of the program were recommended to be terminated and others recommended to be continued (some with specific alterations). Table 1-1 summarizes those recommendations,-

which were contained in the monitoring report for.1984 (TVA. 1985) and approved by EPA on July 15, 1985. TVA implemented the recommendations immediately upon approval.

On August 29, 1986, TVA submitted a report (TVA, 1986)'to EPA on results of studies conducted in 1985. That report included results of components.which had been recommended for termination (data collected in 1985' prior to EPA's approval) and results of continued / altered components of the program conducted in 1985. Results of components terminated after

. July 1985 were similar to those of previous years. Findings of continued /.

altered components and subsequent recommendations are described below:

(i) SQN altered distribution of DO in the water column at and downstream

~

of the diffusers during periods of low river flows. Studies to define the extent and duration of the DO alterations were recommended to allow evaluation of potential for effect on aquatic life.

(2) Observed decreases in plankton densities from upstream to downstream of SQN during low-flow periods in July 1985 were largely due to SQN..These results also allowed further refinement of recommendations whereby sampling would

- be conducted during selected conditions of river flow and plant operation necessary to complete evaluation of SQN effecte on plankton. TVA recommended that a technical report on plankton studies not be submitted until sufficient information had been gathered under the selected conditions to complete this evaluation, although a status report on plankton evaluation would be submitted in January of each year starting in 1988. (3) The 1985 larval fish studies provided basically the same results as previous years--low entrainment rates for all species except freshwater drum. 1herefore, sampling for fish larvae was. discontinued in spring 1986 and that effort was redirected to evaluate effects of the high entrainment rates on the freshwater drum population in Chickamauga Reservoir. (4) Cove rotenone sampling in 1985 indicated operation of SQN has not significantly impacted fish standing stocks in Chickamauga Reservoir, with the possible exception of freshwater drum. Cove rotenone studies were recommended to be continued because they remain the best overall method for determining reservoir-wide quantitative and qualitative changes in fish populations.

The purpose of this report is to present results of studies conducted in 1986. SQN WHN shut-down in August 1985 and did not resume _-

e operation in 1986. Therefore, recomunended studies which required plant operation were not conducted. Studies which were conducted in 1986 and reported here include the freshwater drum population evaluation and cove rotenone studies.

2.0 SPECIAL STUDY TO EVALUATE FRESHVATER DRUM POPELATION_NEAL SE_QUOLA_H NUCLEAR P W T P

2.1 Materials and Methods Adult freshwater drum were collected with experimental gill nets from TRM 482.7 downstream, to TRM 487.6 upstream of the SQN plant site (TRM 484.5).

Each net was 68.6 m long and 2.4 m deep, with 7.6 m panels ranging in mesh size from 2.5 to 12.7 centimeters (cm) in 1.27 cm increments. Areas sampled near SQN included:

(1) upstream of the plant intake, (2) downstream of the diffusers, and (3) in the immediate vicinity of the underwater dam. Nets were tended daily and mesh size succession reversed for those nets reset in the same general location on.

successive days. A descriptior. of each net site was recorded daily.-

Nets were fished from May 12'through June 25, 1986. This time-frame was chosen to correspond with the approximate peak spawning period of freshwater drum. All fish collected in the nets were identified to species, counted and recorded. Total length, weight and maturity stage (table 2-1) were recorded for each freshwater drum and a scale sample.

taken for age an.1 growth analysis.

Scales were pressed onto cellulose acetate slides and. read utilizing a binocular microscope. A drawing attachment on the microscope superimposed the magnified scale image onto a digitizing pad. attached to an IBM personal computer. As each annulus was electronically marked on the pad, data were entered into the computer and analyzed using software developed by Frie (1982) and modified for IBM use.

Program output included calculation of the linear relationship between total length and !

scale radius utilizing Duncan's_(1980) algebraic estimate of the body-scale constant, and calculation of total lengths at each age _ class prior to' capture. Characteristics described by Swedberg (1965) were used to separate the true and false annuli.

2.2 Results and Discussion Sixty-eight gill net'-nights of effort resulted in a total catch i

of 2,015 fish (table 2-2)' representing 29 species and one hybrid (white x striped bass). Catch was dominated by. gizzard shad (43.5 percent),

freshwater drum (16.9 percent) and blue catfish (10.8 percent). Catch per unit effort of freshwater drum (5.0, number = 341) was second only to that of gizzard shad (12.9) and both species occurred in 93 percent (63) of the net-nights fished.

Total length for 341 freshwater drum ranged from 113 to 765 mm.

Results of body-scale analysis for 328 (13 fish could not be aged) fresh-I water drum revealed 14 year classes (age 1-14) dominated by fish three, four, and five years old (figure 2-1).

Estimated total lengths (mm) at each annulus appear in table 2-3.

Average annual growth increment for freshwater drum from Chickamauga Reservoir (table 2-4) was 42.7 mm (ages 1-14) compared to 58.2 mm (ages 1-6) for 228 drum collected during i

preoperational monitoring (TVA, 1978) and 23.9 mm (ages 1-10) for nearly 5,000 freshwater drum analyzed from combined mainstream Tennessee River reservoirs (analyzed from historical data). Mean estimated total length at each annulus, however, shows that all age classes of f reshwater drum in this study were larger than those collected during preoperational _

e monitoring (except-for those in age class six). Mean total lengths for mainstream Tennessee River reservoir data also were less than those for the present study with the exception of age classes 2 and 3 which were-equal or very similar (table 2-4).

Sex and maturity stage were determined at time of collection for 178 males and 150 females (table 2-5). During the first week of sampling (May 12 through 17), maturity stage data indicated three freshwater drum (2 females,1 male) were in spawning condition. Number of females observed in spawning condition was highest (21) during the 2

first week of June, while more males in spawning condition were collected i

during mid to late June. Previous estimates of' freshwater drum egg densities have consistently shown higher numbers of eggs below the SQN I

diffuser structure than were collected upstream at the plant transect.

In an attempt to support the hypothesis that more intensified spawning by freshwater drum occurs downstream of SQN than upstream, numbers of adul~t j

freshwater drum collected during this study in maturity-stage VI i

(spawning, table 2-1) were compared from nets set upstream and downstream of the dif fuser.- Ratios of upstream: downstream distribution were approximately 1:1 for males and 1:2 for females. These data tend to l

support the premise that greater magnitude of freshwater drum spawning i

occurs below SQN than above.

Numbers of freshwater drum captured in each year class (figure 2-1) were compared to annual estimated entra'innent (percentage) -

i of freshwater drum eggs and larvae at SQN during 1981 through 1985.

If, during the years of highest entrainment, losses of eggs and larvae significantly impacted survival of the year class (es), subsequent age i j

l 7

analysis of the population should indicate relatively weak or missing year classes. Estimated entrainment of freshwater drum eggs was highest (28.5 percent) in 1982, and second highest (21.8 percent) in 1983. The year classes produced during these two years coincide with the two mor,t abundant (figure 2-1) age classee (four and three years old, respectively) collected during experimental gill-net sampling in 1986.

Entrainment of freshwater drum larvae at SQN was highest (58.2 percent) in 1983, followed by 1982 (46.8 percent). As observed with freshwater drum eggs, the year classes produced during the tiro years of highest estimated larval entrainment proved to be the most abundant (in reverse i

order) collected with experimental gill nets during this study. These data also lend credence to the hypothesis presented in the most recent SQN operational monitoring report (TVA, 1985) that large numbers of freshwater drum are spawned below SQN where they are not subject to entrainment. Therefore, it appears that even when large percentages of eggs and larvae passing the plant are entrained, recruitment to the adult population is not significantly affected.

2.3 Summary and Conclusions Analysis of age structure and year-class composition for freshwater drum in Chickamauga Reservoir reveals that strongest year classes were recruited to the population during the first three years in which SQN was operational (1981-1983). The 1982 and 1983 year classes were the strongest of fourteen collected with experimental gill nets in this study. Estimated entrainment rates of freshwater drum eggs and _ _ _ _ _

J larvae were also highest during th'ese same two years, thus contradicting the idea that the freshwater drum population might have been signifi-cantly affected by entrainment losses during this period.. Consistently higher numbers of freshwater drum eggs spawned below the SQN diffuser.

(and thus not s'sceptible to entrainment) further support the conclusion u

of no entrainment-associated impact upon the freshwater drum population i

in Chickamauga Reservoir.

Mean total lengths at each year class of freshwater' drum in

. Chickamauga Reservoir collected during 1986 were higher (with the exception of one year class) than those for freshwater drum collected

)

during preoperational monitoring as well as higher than (or equal to) j those of nearly 5,000 freshwater drum previously analyzed from other mainstream Tennessee River reservoirs. In spite of decreasing trends of j

young and intermediate stocks of freshwater drum indicated from cove rotenone surveys, the population of adult freshwater drum in Chickamauga-Reservoir appears to be above normal in terms of age' class composition and rate of growth. The overall conclusion combined with.results of preoperational and operational monitoring is that the freshwater drum population of Chickamauga Reservoir has not been adversely impacted by j

the operation of SQN.

i 3.0 COVE ROTENONE Cove rotenone sampling is a quantitative, active sampling method.

Fish in a cove are isolated from the res't of the reservoir by a block net.

Toxicant (rotenone) is then applied and all fish are collected, yielding quantitative estimates of fish populations in coves. These estimates are not necessarily equivalent to standing stocks in the entire reservoir, nor are they true population estimates because fish species are not distributed evenly throughout the reservoir. More effective estimates are possible for species and certain age / size groups of selected species, which orient more toward shoreline or structure than open water habitat. However, cove rotenone sampling represents the best 4

overall quantitative method for estimates of relative abundance in south-

. eastern reservoirs. As such, these data provide estimates of reproduc-tive success, year-class strengths, and fish stock sizes. Cove rotenone data are useful in determining long-term trends of these parameters for various species in a reservoir.

3.1 Materials and Methods Fish sampling with rotenone was initiated in Chickamauga Reser-voir in 1947 to determine standing stock (v:Imbers/ha and kg/ha) of game, prey, and commercial fish species. Samples were taken at various loca-

[

tions, primarily in coves, annually through 1959, except for 1948 and 1

1953. In addition to standing stock information, these data provided

~

species occurrence and composition information and characterized the fish l t l

community of the reservoir. Sampling was discontinued after 1959 but was resumed in 1970 to collect preoperational data for monitoring possible impacts from the operation of Sequoyah Nuclear Plant (SQN).

Rotenone sampling procedures in TVA were standardized after 1960 to include use of block nets and standard survey techniques. Prior to this, techniques varied from year to year and from one reservoir to another. Sampling in Chickamauga Reservoir from 1947 through 1959 was characterized by the use of varying techniques for determining arec and volume of the sample site and varying or undescribed sampling and sub-sampling techniques.

Field Cove rotenone sampling since 1970 was designed to eliminate certain biases through establishment of criteria for sample sites and standardization of field techniques. Criteria for an acceptable rotenone site are: (1) surface area at least 0.4 ha; (2) depth not more than 7.5 m where block net is set; (3) location not adjacent to or within the same cove as housing developments, boat docks, or other recreation areas; (4) absence of sensitive habitats; and (5) easy access by boat. During operational monitoring, five coves were-sampled each year in Chickamauga Reservoir. These coves were located at TRM 476.2, 478.0, 495.0, 508.0, and 524.6 (figure 3-1).

Descriptions of sample sites (1947-1986) are in table 3-19.

Standardized fleid techniques for rotenone sampling include:

(1) sampling when water temperature is > 20' C; (2) accurate surveying of surface area one day prior to conducting sample; (3) block net set on the _ _ _ _ _ _ _ _

afternoon prior to sampling; (4) scuba-diver check of block net to ensure isolation of sample area; (5) determination of physical and chemical properties of the sample area; (6) application of rotenone to attain a 1.0 mg/L concentration of toxicant; (7) pickup of all visible fish on two consecutive days; and (8) specified sorting, counting, weighing, sub-sampling, and data recording procedures.

Physical properties measured were surface area, maximum depth, and mean depth (obtained through a systematic series of depth soundings). Mean depth and surface area were used to determine the volume of the cove and thereby, the amount of toxicant necessary to achieve a concentration of 1.0 mg/L.

Rotenone was applied with a pump using a weighted, perforated hose to distribute the toxicant evenly at all depths.

Initially, a curtain of rotenone was applied adjacent to the block net to prevent small fish from escaping. Following this, rotenone was distributed by cperating the boat in a zigzag pattern throughout the cove. Finally, shallow shoreline areas were surface-sprayed with rotenone to ensure complete coverage of the area. Visible fish were picked up the day of application and sorted by species. Each species was then sorted into groups by 25 mm length increments. Small fish (e.g., Notropis sp.) that were not readily identifiable in the field were preserved in 10 percent formalin and returned to the laboratory for identification. Each size group was counted and the aggregate weight recorded. Occasionally, some length groups were so numerous that it was not practical to count each fish.

In these cases, a subsample of that length group was counted and.

weighed. The remainder of the size cla:.s was then weighed collectively and numbets estimated by the relationship:

Numbers in. Weight of. Numbers in. Weight of subsample subsample remainder remainder Since 1982, a modified subsampling procedure has been used te process large n tmbers of young certrarchids (Lepomis sp.).

Small centrarchids (< 76 mm total length) were separated from the remaining cove sample, and a 1 kg subsample was processed. Fish in the subsample were sorted to species, separated into 25 mm length groups, then counted and weighed. The remainder of the sample was weighed collectively.

Numbers of each species and size group were then determined by using a relationship similar to that described above. Fish collected the second day were processed in the same way, except that numbuts only were recorded for each size class of each species. Weights of second-day fish-were calculated from length-weight relationships derived from first-day fish.

Data Analyses Standing stocks of each species were calculated by size class.

Fish were grouped into game, commercial, and prey species and classified as young, intermediate and adults, based on total length (table 3-20).

Standing stocks of young, intermediate, and adult size classes of impor-tant species were analyzed using a linear regression model to determine statistically signit Icant trenda over the period 1970 through L986.

Important species were determined by the'following criteria:

-1.

Must occur in at least 50 percent of samples since 1970, and' 2.

Must comprise one percent of either the total number or total biomass collected.

In addition to species meeting the above criteria, certain species of special interest were included' for analysis because of their-importance as' sport or commercial species. For each important species, or species of special interest, Kruskal-Wallis rank sums analyses as rouified by Dunn (Hollander and Wolfe, 1973) were used to determine et rgificant standing stock differences among three areas of Chickamauga 4

Reservoir for the preoperational period (1970-1979) and operational period (1980-1986). Areas of the reservoir were defined as: (1) down-stream area (TRM 471.0 to TRM 484.5), two coves; (2) middle area (TRM 484.5 to TRM 500.0), one cove; and (3) upstream area (TRM 500.0 to 529.9), two coves.

3.2 Results and Discussion In 1986, 42 species representing 12 families were e,ollected in cove rotenone samples in Chickamauga Reservoir (table 3-3).

All species collected in 1986 previously had occurred in cove rotenone samples for preoperational and operational monitoring in this reservoir (table 3-4).

Numerically, bluegill was the most abundant species (36 percent),

followed by gizzard shad (19 percent), redear sunfish (17. percent), and __

threadfin shad (14 percent). Gizzard shad comprised 63 percent of the total biomass sampled, whereas biomass of bluegill, redear sunfish, and threadfin shad were 8 percent, 4 percent, and 2 percent, respectively.

Freshwater drum made up about 4 percent of the biomass, but comprised only 0.3 percent of the total number.

Total standing stock of young, intermediate, and harvestable size classes of fish in Chickamauga Reservoir in 1986 was 36,188 fish /ha, with a biomass of 345.7 kg/ha (table 3-5).

Young-of-year fish repre-sented 92 percent of the standing stock by number and 18 percent of the biomass. Harvestable and intermediate size fish comprised 73 percent and 9 percent of the biomass, and 5 percent and 3 percent of the number, i

respectively.

Forage species dominated biomass again in 1986 (232 kg/ha, 67 percent, table 3-6).

Game and commercial fish comprised about 21 percent (72 kg/ha) and 12 percent (42 kg/ha) of the biomass, respec-tively. Fifty seven percent of the fish population by number were young-of-year game fish, primarily bluegill, redear sunfish, warmouth, and redbreast sunfish. Young-of-year fish comprised eight percent of the total biomass.

Cove rotenone samples in Chickamauga Reservoir from 1970 through 1986 yielded 71 species belonging to 15 families (table 3-4).

Bluegill vas the predominant species comprising 41 percent of the total number of fish collected (table 3-7).

Only three species (gizzard shad, bluegill and f reshwater drum) were present in all cove samples f rom 1970 through 1986 (table 3-7).

Numbers of young fish were highest in 1981, and biomass of har-vestable fish was highest in 1983, 1984, and 1985 (table 3-5).

Table 3-6 shows a general increase in numbers and biomass of game fish from 1970 through 1983 with no distinct trend for either commercial or prey fish groups. Forage fish biomass, while increasing substantially from 1983 through 1985, decreased dramatically in 1986. Game fish biomass remained relatively stable from 1977 through 1986 and peaked in 1981.

Detailed presentation of spatial and temporal data from Chickamauga Reservoir cove rotenone samples during 1970 through 1986 are in appendices A through F.

These include mean numbers (A) and biomass (B) per hectare by species for each cove sampled; percentage composition (no./ha) by species and cove (C); percentage occurrence by species and cove (D); mean annual number (E) and biomass (F) per hectare for all coves combined.

Important Species Nineteen species were cla: 41fied as important or of special interest in cove rotenone samples (table 3-7).

Results of linear regression analyses (table 3-8) and numerical abundance and biomass of young, intermediate and adult size classes of each species through time are discussed below. Spatial differences among the three areas of the reservoir (tables 3-9 through 3-12) also are discussed.

Gizzard Shad--Adult gizzard shad biomass has increased since 1983 (table 3-13).

Ifowever, from 1970 through 1986 no statistically significant trends were found for either numbers or biomass of adult gizzard shad in Chickamauga Reservoir. Number and biomass of young-of-year gizzard shad continued to show a significant increasing trend, approaching 6700/ha and 22 kg/ha respectively, in 1986.,

I Spatial distribution analyses during preoperational monitoring

~l (1970-1979) indicated greater numerical abundance' in the upstream area of Chickamauga Reservoir than in either middle or downstream areas.

i Statistically significant differences in biomass were found between the upstream and middle areas during preoperational monitoring (greater biomass upstream). Operational monitoring analyses (1980-1986) indicate l

that'a significantly larger biomass of gizzard shad was found in the downstream area than in the upstrase areas.

Threadfin Shad--Over 6he period 1970 through 1984, numbers and biomass of young-of-year threadfin shad showed a significant decline.

Extremely cold winters in 197 7-1978,1,978-1979, and 1983-1984 apparently cot.cributed to this decline. Following an abrupt increase in biomass-in 1985 (92 kg/ha), standing stocks returned to near normal levels (9 kg/ha) in 1986. No significant differences in numbers or biomass were found among the three areas of Chickamauga Reservoir during either preopera-tional or operational monitoring. Estimated numbers of threadfin shad in 1985 were about 23,000/ha compared to about 5,000/ha in 1986 (table 3-14).

Although other environmental / compensatory mechanisms may have influenced the dramatic increase in threadfin shad in 1985, more open water along shorelines and coves in 1985 than in other recent years.

Likely contributed to the record high stock estimate of this species.

Increased open water habitat was the direct result of an experimental summer drawdown of Chickamauga approximately one month before cove areas were sampled. Houser and Bryant (1968) indicated that in the absence of aquatic weeds, cove standing stocks of threadfin shad were equal to open water stocks in two Arkansas reservoirs. The strong recurgence of.

aquatic weeds in 1986 apparently restricted threadfin shad from reservoir cove areas.

Carp--Young-of-year carp increased significantly (both numbers l

l and biomass) in Chickamauga Reservoir over the period of study (1970 through 1986), but no atatistically significant trend was observed for numbers or biomass of intermediate or adult carp.

In previous analyses (TVA, 1978b; 1980), no significant trends were observed. However, in these reports it was noted that cove rotenone probably does not provide a representative sample of smaller size classes of this species (cable 3-15), and statistically significant increasing or decreasing trends should be qualified.

Biomass and numbers of carp were significantly higher in the upstream portion of Chickamauga Reservoir (TRM 500 to TRM 529.9) than in other areas during preoperational monitoring (tables 3-9 and 3-10).

Results of cove rotenone samples during operational monitoring indicate a significantly higher carp biomass in the upstream area of the reservoir than in the downstream area.

Bullhead Minnow--Bullhead minnow occurrence prior to 1971 was sporadic, but this observation may have been due to misidentification of this species. Since 1971, stocks have been relatively high (table 3-16) and have shown an increasing trend through time. No significant differ-ences in standing stocks were found among the three areas of the reser-voir during preoperation. Following operation, numbers were signifi-cantly higher upstream than in the middle area until 1985, but this is no longer the case. r a

Smallmouth Buffalo--Over the period 1970 through 1986, both numbers and biomass of intermediate and adult size classes of this species have declined significantly. However, total numbers (40/ha) of smallmouth buffalo increased in 1983 and were similar to levels observed in 1971 and 1972 (table 3-17). No significant differences in standing stocks (numbers or biomass) of this species among the three areas of Chickamauga Reservoir have occurred under preoperational (1970-1979) or operational conditions (1980-1986).

Spotted Sucker--Biomass and numbers of young-of-year spotted sucker show a significant decreasing trend. Spotted sucker was not identified in rotenoue samples in Chickamauga Reservoir prior to 1959.

As noted in a previous report (TVA, 1982), this species may have ended an expansion phase in Chickamauga about 1979. However, af ter total biomass creased slightly in 1985, it decreased in 1986 to the lowest level 8

since SQN operational monitoring began (table 3-18).

Significant differ-ences in standing stocks of spotted sucker among the three areas of the reservoir have not been noted during operational monitoring, whereas in preoperational analyses, biomass of this specias was significantly greater in the upper area than in the middle area.

Channel Catfish--In 1986, total number and biomass of this species was found to be at its lowest levels since starting the SQN moni-i toring program. A declining trend (both numbers and biomass) was also noted for intermediate size channel catfish in previous reports (TVA, l

l 1978b; 1980; and 1983). Except for 1981, estimated total biomass of channel catfish has been less than 15 kg/ha tabie 3-19).

No significant differences were noted among the three reservoir areas during either preoperational or operational monitoring for SQN. _

Flathead Catfish-Total biomass estimates for flathead catfish since 1970 have seldom exceeded 1.0 kg/ha (table 3-20). Through 1983 no significant trend for biomass or numbers of any size class of this species was determined, but in 1984 numbers and biomass of adults showed a significant decline. Since 1983, no intermediate flathead catfish have been collected. Although few were collected, numbers of this species were highest in the reservoir mid-section during preoperational moni-toring. During operational monitoring, numbers and biomass in the middle area were also significantly greater than in the upper and downstream areas.

White Bass-Numbers of adult white bass in 1986 were equal to, and biomass nearly as high as the highest levels recorded (1984) since monitoring began (table 3-21).

Young white bass, absent in 1983 and 1984 samples, recovered strongly in 1985 and 1986 when biomass was highest observed since monitoring began.

Intermediate size white bass numbers and biomass also increased dramatically in 1986 (1/2/ha and 12 kg/ha, respectively) over all previous years. No significant stock differences were fot.nd among the three reservoir areas since SQN operation began.

However, during preoperational monitoring, both numbers and biomass of white bass were significantly higher upstream than downstream.

l Yellow Bass-All size classes of this species have increased significantly (both numbers and biomass) since 1971. Because yellow bass did not meet criteria for important species in preoperational analyses for SQN, this trend was first documented in the WBN preoperational moni-I toring report (TVA, 1980). During 1,reoperational monitoring and since operation began, no significant differences in the standing stock among 1 _ _ _ _ _......

t the three reservoir areas were detected. Total biomass for -this species was highest (10 kg/ha) in 1981, and total numbers were highest in 1982 (table 3-22).

Warmouth--All three size classes of-this species have increased

-v significantly (both numbers and biomass) through time. Number and biomass, down in 1985, returned to normal levels in 1986. Warmouth did not meet criteria for "important species" status when SQN preoperational studies were analyzed (TVA, 1978b). When data were analyzed for the WBN preoperational report (1970-1979), warmouth abundance had increased to meet these criteria. Linear regression analyses for WBN preoperational monitoring revealed that, except for numbers of young warmouth, all size groups were increasing significantly. Numbers per hectare of young warrauth had increased, but the trend was not statistically significant.

No significant dif ferences in numbers or biomass were found among the three areas of the reservoir during preoperation. Since operation, numbers have been highest in the middle area. For six of the past seven years, total numbers have exceeded 1,000/ha (table 3-23).

Bluegill--Numbers and biomass of young-of-year of this species have increased significantly through time. A significant increasing or f

decreasing trend for other size groups was not determined. Estimated total biomass for this species f requently has been above 30 kg/ha (table 3-24).

During preoperational monitoring (TVA, 1978b),'only numbers of young bluegill exhibited a significant increasing trend.

Preoperational data analyses for WBN (TVA, 1980) indicated numbers of all three size classes increased, while biomass of only the young size class showed a similar trend. As indicated in previous analyses (TVA, 1983),,- -

i t

an increase in aquatic-vegetation in Chickamauga Reservoir has contri-buted to higher standing stocks of centrarchids, particularly young-of-2

- year. In contrast to the preoperational period, significant differences were,found among-the three areas of the. reservoir since operation began.

Numbers were significantly less in the upper area relative to the down-stream and middle area. -Biomass was significantly less in the upper area

.than.in the downstream area.

Lonaear Sunfish--No significant trends have been observed for 4

this species. Previous analyses (TVA,1978b; 1980) showed increases for young and intermediate sizes, although adults exhibited no trend. Both i

j numbers and biomass of this species were significantly lower upsttsam than in either of the other two reservoir areas in both the operational l

and preoperational periods. Total biomass was less than 5 kg/ha'for the 1970-1986 pericJ (table 3-25).

Redear Sunfish--Total biomass for this species in 1986 was f12 i

kg/ha (table 3-26).

As in previous analyses, biomass and numbers of young redear sunfish showed a significant increasing trend (table 3-8).'

Biomass and numbers of the interme?". ate size class also showed a signifi-l cant increasing trend. This general increasing trend is probably related to increased aquatic macrophytes in Chickamauga Reservoir. Operational monitoring numbers were significantly lower in the upper reservoir area relative to the downstream area.

Largemouth Bass--Through 1983, numbers of all three size classes I

of largemouth bass showed an increasing trend (TVA, 1984). From 1984 to 1986, biomass of young-of-year and numbers of intermediates continued to

)

show a signiticant increase. A significantly increasing trend for:

numbers and biomass of adults was documented through 1985. Total biomass was 5 kg/ha in 1986, the lowest biomass found during operational moni-toring (table 3-27).

No significant difference-in abundance among the three areas of the reservoir was determined during preoperational monitoring, but during operational monitoring (1980-1985), biomass and numbers in the middle and downstream areas were significantly higher than the upstream area.

Abundance of all size classes of largemouth bass may be directly related to increases in young bluegill and other centrarchids. However, deteriorating water quality in backwater cove areas due to drought condi-tions in 1986 may have reduced largemouth bass stocks in coves.

White Crappie--Numbers and biomass of adult white crappie decreased to record low stocks in 1986 (table 3-28).

Previous data analyses for the SQN preoperational report also revealed declining numbers and biomass of adults (TVA, 1978b). Biomass of the intermediate size class continued to show a decreasing trend. Neither increasing nor decreasing trends were found for numbers or biomass of young white crappie. White crappie were significantly more abundant (both numbers and biomass) in the upstream area of Chickamauga Reservoir than in the middle and downstream areas during preoperation. Since operational monitoring began, numbers in the middle and upstream areas were significantly greater than the downstream area (table 3-11).

Since 1970, total biomass of white crappie estimated by cove rotenone samples, has not exceeded 5 kg/ha.

Sauner--No sauger were collected in Chickamauga cove rotenone I

samples from 1980 through 1984. Adults only were collected in 1985 and i -

1986 (table 3-29).

No significant differcnces were found among the three areas of the reservoir during preoperational or operational monitoring.

Yellow Perch--Both numbers and biomass of adults had a signifi-cant increasing trend. This species apparently became established in Chickamauga Reservoir sometime af ter 1959 and young perch first appeared in cove rotenone samples in 1970. Adults were first collected in cove rotenone samples in 1978. At the time data analyses were performed for the SQN preoperational report (TVA,1978b), only young had been collected, and no trend could be determined. At the time data analyses were performed for WBN preoperational report (TVA, 1980), intermediate and adult size classes had only been collected for two years, but linear regression analyses showed increasing trends. Most recent results confirm that this. species has become established in Chickamauga Reservoir and the population is expanding, although total biomass has not exceeded i

5 kg/ha (table 3-30). During the operational and preoperational periods, significant spatial differences in abundance of this species were determined. During preoperational monitoring, biomass and num'bers were higher in both the middle and downstream areas than in the upstream I

Currently, numbers and biomass in the middle area are signifi-area.

cantly higher than those upstream and downstream.

Freshwater Drum--Linear regression analyses (1970 through 1986) revealed no significant increasing or decreasing trends in adult stocks.

Similar analyses, however, revealed that both numbers and biomass of young and intermediate size freshwater drum hav-declined in Chickamauga

(

Reservoir. These apparent trends were first documented prior to Unit i fuel load at SQN (TVA, 1980). Mean annual numbers and biomass (table i

i,

\\

3-31) show a possible cyclic pattern for these two size groups; stocks were high in_the~early-to mid-1970s, decreased through the late 1970s and early 1980s and subsequently increased through 1985J Young-of-year

~ numbers -in 1985 were the highest since -1973, while intermediate numbers

~

in 1985 were the highest since 1977. Total numbers (all sizes combined) of freshwater drum in 1986 were the lowest observed since 1970 and biomass was second lowest.

The apparent. reductions or cycling in young and intermediate stocks are not considered ecologically significant unless they are ulti-mately reflected in reduced stocks of adults. However, because high entrainment rates of freshwater drum were noted at SQN (TVA, 1985), TVA conducted investigations in 1986 to determine if entrainment losses were affecting the freshwater drum population in Chickamauga Reservoir.

Results of those investigations are presented in chapter 2.

Other than entrainment effects, reduced stock estimates of young and intermediate sizes of freshwater drum may be related to the signifi-cant increases of aquatic macrophytes in the reservoir since the mid-1970s. From 1976 through 1983, there was a 7-fold increase in the acreage affected by rooted aquatic vegetation in Chickamauga Reservoir (TVA, 1986). Unlike many of the centrarchids, young and intermediate sizes of freshwater drum seem to prefer open-water areas and to avoid coves with dense aquatic vegetation. Young and intermediate freshwater-drum have been more abundant in the uppermost sample cove in Sewee -Creek (TRM 524.6) where aquatic macrophytes have always been absent.

In the preoperational period for SQN (1970-1979) and most of the operational period (1980-1984), numbers and biomass of f reshwater drum I

1 i

.. -.. -.. ~. -

were found to be most abundant in the upstream portion of Chickamauga Reservoir..In late July and early August 1985, approximately one month before cove rotenone sampling was performed. TVA conducted an experi-mental drawdown of Chickamauga Reservoir for aquatic plant control. The drawdown was effective in reducing aquatic macrophytes in shoreline areas throughout the reservoir, including the coves sampled with rotenone.

When the reservoir was refilled following the drawdown, additional open water habitat was available. This change, favorable to those species preferring open water and/or " edge" habitats, appears to have been at least partially responsible for higher stock estimates of young and intermediate freshwater drum in 1985 and the more even distribution of numbers and biomass of this species among the coves sampled. The dramatic increase in aquatic macrophytes in and surrounding the down-stream, middle, and TRM 508.0 (upstream area) coves apparently limited freshwater drum stocks in these areas in 1986.

3.3 Summary and Conclusions Cove retenone sampling does not provide representative stock estimates of all species; however, it remains the best overall fish sampling method for determining quantitative and qualitative changes in i

species composition the reservoir fish population. Based on cove rotenene sampling since 1970, which included 10-year preoperational and 6-year operational periods, operation of SQN has not had a significant adverse impact on fish standing stocks in Chickamauga Reservoir.

Both increasing and decreasing trends have been noted among species ranked dominant and/or important, but-total fish biomass has remained relatively stable. Some species'(e.g., flathead' catfish, sauger and wh'ite crappie) that showed decreases in biomass for one or more size classes were those for which cove rotenone generally does not provide a representative sample. On the other hand, species that showed signifi-cantly increasing trends (e.g., bluegill, gizzard shad and largemouth bass) were those for which cove rotenone usually provides better esti-n.ates of relative abundance.

The overriding influence on standing stock estimates for many of j

the important fish species appears to be associated with habitat altera-

tion, i.e., the seven-fold increase in aquatic vegetation in shallow overbank and cove areas of Chickamauga Reservoir which occurred from 1976 through 1983. Thin has resulted in higher standing stock estimates for various centrarchids, particularly warmouth, redear sunfish, bluegill, and largemouth bass. Although numbers and biomass of largemouth bass showed a decline in 1986, drought-induced deteriorating water quality conditions may have resulted in fish avoiding shallow coves. Whether 1

aquatic vegetation has resulted in a decrease in biomass-or numbers of i

some fish species (e.g., threadfin shad, smallmouth buffalo, white 2

l crappie, white bass, and freshwater drum) is not clear. However, the experimental summer drawdown of Chickamauga Reservoir in 1985 produced i

conditions that support previous assumptions regarding the avoidance by I

freshwater drum and threadfin shad of densely vegetated coves. This pre-l mise was further supported in 1986 with the dramatic return of aquatic :

i

m i

macrophytes in cove areas and the corresponding decrease of freshwater drum and threadfin shad standing stocks in coveirotenone' surveys.

Cove rotenone samples have indicated a decline'in numbers and

' biomass of young and intermediate size freshwater drum..The declining trends of young and intermediate size freshwater drum, however, were-first documented prior to SQN Unit i fuel load. Reductions in young and intermediate stocks are not considered ecologically significant unless they are ultime*.ely reflected'in reduced stocks of adults. Neither significant increasing nor ' decreasing trends in adult freshwater drum stocks have been identified from rotenone samples.

Although fluctuations in total fish-standing stocks have been 1

l observed in cove rotenone studies, they do not appear to have been i

related to SQN operation. Analysis of data from cove rotenone sampling since 1970, indicates no significant adverse impact on fish standing stocks in Chickamauga Reservoir from operation of SQN.

4.0 CONCLUSION

S AND RECOP9tENDATIONS Freshwater Drum Evaluation--The intensive investigations conducted in 1986 provided information showing that entrainment of relatively large numbers of freshwater drum eggs and larvae through SQN had not adversely affected the population in Chickamauga Reservoir.

Therefore, it is recommended that no further freshwater drum investiga-tions, evaluations, including those pertaining to eggs and larvae, be conducted.

Cove Rotenone Surveys--Based on cove rotenone sampling since 1970, total fish biomass in Chickamauga Reservoir has remained relatively stable.

It is concluded from sixteen years of preoperational (10) and operational (6) monitoring that operation of SQN has not had a significant adverse impact on fish standing stocks in Chickamauga Reservoir.

Annual fish sampling using rotenone in coves should continue as presently being conducted with one exception. The uppermost cove in Chickamauga (Sewee Creek) should be deleted since it is questionable that data from this location are representative of reservoir fish populations. With regard to data analyses on the remaining four cove samples, important species discussions should be limited'to those species meeting established criteria for important or dominant species. Also, reservoir zone comparisons should be discontinued.,
