1.1 STAT)0N COOLING WATER SYSTEMS TiiERE\L LIMITS Specification A. The cooling uater effluent temperature at the discharge shall not exceed 100 F for a time period of excess of two hours. In the event of the once-in-20 years combination of extreme natural conditions the station's generating capacity shall be limited as necessary to keep the discharge temperature from exceeding 100 F unless there is a serious uced for the lost power. A serious need for lost pcuer is defined here as a condition which would result in voltage reductions or load shedding (except contracted interruptable loads). Under these circumstances, the licensee shall notify AEC/ DOL immediately by telephone and the discharge temperature shall not be allowed to exceed 1030F.
B. Temperature rise from the condenser intake to the discharge shall not exceed 280F. Further, the temperature rise should not exceed 220F when the inlet temperature is greater than 680F.
C. Normal station operations shall be programmed so that effluent temperatures shall not decrease more than 6 F per hour during the winter and 100F per hour during the spring, summer, and fall.
I. INTRODUCTION The noted specifications were established to evaluate the effects of thermal discharges on aquatic life in the vicinity of Oconee Nuclear Station. The limits on station discharge temperature, temperature rise acros's the condensers, and rate of decrease of the discharge temperature permit sufficient operational flexibility to allow for the starting or shutdown of a circulation water pump during unit lead changes. Under nornal operation, station procedures incorporate the progranming of load changes to minimize the resulting transient thermal change.
II. RESULTS The station daily average condenser intake and discharge temperatures and flow rates for the period July 1 through December 31, 1074 are presented in Table 1.1-1 and Figure 1.1-1. The station daily average CCW flow rate was c.htained by adding the daily average f1cw rate fer each of tha three units. The average daily flow rates for the individu 1 units were derived utilicing the CCW Equipment Running Time Ecport to determine tha number of hourc the CCW pumps were in operation during each day (24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />). If the nurbar of pumps operating increased er decreaned during the day, the daily average flow rate was cbtained by 1.1-1 OSd 12/74
- ,_ __ -_ _ __- . . - ~_
ratioing hours pump (s) operated, times the flow rate of the pumping situation and summed to equal the daily average flow rate. The flow rates for the various pumping situations-for each unit (4 CCW pumps per unit) are as follows:
One (1) CCW Pump Operation = 243,000 gpm Tuo (2) CCW Pump Operation = 453,000 gpm Three (3) CCW Pump Operation = 594,000 gpm Four (4) CCW pump Operation = 678,000 gpm The station daily average intake and discharge temperatures and AT were derived as follows:
- 1. The daily average intake temperature for each unit was 4 obtained by averaging the hourly average intake temperatures il from the Environmental Monitoring Report (EMR). The daily average intake temperature for each of the (3) units was then averaged to obtain the daily average intake temperature for the station.
- 2. The daily average discharge temperature was obtained by adding the daily average AT to the daily average intake temperature.
- 3. The daily average AT was derived by multiplying the three (3) individual unit AT's (daily average unit intake temp-erature minus daily average unit discharge temperature) times the average daily unit flows. The product from each unit was added and the sum was divided by the total station daily average flow rate.
The Environmental Monitoring Report Computer program failed to operate properly and neither station nor unit data were typed out as required for the following times during this reporting period:
1600 September 13, 1974 to 1100 September 14, 1974 1000 September 15, 1974 to 1600 September 15, 1974 1100 September 20, 1974 to 1000 September 21, 1974 The monitoring requirements of Technical Specification 1.1, Appendix B requires representative data be manually logged hourly when the EMR Coeputer Prograu fails. Data was not logged as required except for the period 1100 to 1600, September 15, 1974. During the time the comput.:
was out the station was operated at 43 to 68 percent of full power. The reason for the computer failure has been attributed to programming errors during the incorporation of L' nit 3 startup data. Corrective action was implemented and the system is now operating correctly.

III. CONCLUSIONS With respect to Specification A, Table 1.1-1 and Figure 1.1-1 shows .
that the maximum CCJ discharge temperature of 100 F was not exceeded at any time during this reporting period. The maximum daily average temperature of 83.3 F occurred on November 8 and a maximum hourly average of 88.80F occurred on September 17 at 1500. The CCW intake temperature ranged from a low of 52.00F (daily average) on December 31 1 to a high of 73.30F (daily average) on September 26.
With respect to Specification B,, Table 1.1-1 and Figure 1.1-1 shows that the maximum daily average temperature rise (AT) of 16.1 F occurred on November 17. The maximum hourly temperature rise when the intake temperature was Icss than 68 F was 18.8 F which also occurred on 3 November 17 at 0700. The maximum hourly temperature rise when the 3
intake temperature was greater than 680F was 16.60F which occurred on September 14 at 1400. The temperature rise for both situations was well within the limits established by Specification B.
With respect to Specification C, the maximum effluent temperature decrease (6 F - winter and 10 F - spring, summer and fall) was within specifications during normal station operations for this reporting period.
The maximum hourly effluent temperature decrease during the winter period was 4.0 F which occurred on December 25 at 2000. The maximum hourly effluent temperature decrease during the summer and fall period I was 8.9 F which occurred at 1200 on July 5, when Unit #1 tripped off. )

1.2 CHEMICAL DISCHARGE LIMITS Specification:
A. Chemical wastes and the resulting chemical concentrations in the Keowee River shall not exceed the maximum concentrations given in Table 1.2-1,
" Chemical Wastes from Oconee Station".
B. All wate'r discharged from the plant site shall have a pH between 6.0 and 8.5. l l C. Chlorine or other chemical hiocides will not be used for condenser c1 caning.
I. INTRODUCTION . .
The noted specifications were established to insure that chemical concen-trations in the river resulting from station discharges are not toxic to aquatic organisms. A chemical inventory is maintained to determine whct quantities of environmentally significant. chemicals are used and thus to estimate the quantities which are discharged over the period of interest.
In addition, the pH and specific conductance of the waste water collection basin iad effluent from the plant site are determined and recorded daily, and corrective measures are initiated as necessary.

1.3 GENERAL AQUATIC SURVEILLANCE Specification: Surveillance programs shall be conducted to detect and quantify Oconee's effects on water quality, fish, periphyton, plankton, and benthos.
I. INTRODUCTION The objective of the aquatic surveillance program is to determine the effects of Oconee Nuclear Station's (ONS) operation on the aquatic ecosystem of Lake Keowee and the area of Lake Hartwell influenced by ONS thermal and chemical discharges. The current environmental monitoring programs on Lake Keowee and Lake Hartwell are summarized in Table 1.3-1. Sampling station locations are shown in Figures 1.3-1 and 1.3-2.
This report is the third to cover a full six-month period of ONS operation, July 1 to December 31, 1974. Unit Three went into commercial operation on December 16, 1974, thus completing the full generating capacity planned for Oconee. Unit One was shut down for refueling in October, however, so that there was no time during this reporting period that the three units were simultaneously generating at maximum capacity. Unalterable conclusions regarding the long term effects of ONS operation upon the aquatic en-vironment are not yet possible. Some of the conclusions presented in Sections 1.3 through 1.7 of this report are as follows:
- 1. Oconee Nuclear Station's use of hypolimnetic water for condenser cooling has no major detrimental effect on water quality in either Lake Keowee or Lake Hartwell. The volume of the hypolimnion in the Little River arm of Lake Keowee was noticeably smaller than that of the Keowee River arm during July through October, probably caused by withdrawal of hypo-limnetic waters for ONS condenser cooling. Consistent with data presented in the three previous semi-annual reports, higher pH values and oxygen saturation were observed at Stations 500.0 and 501.0 during July and August; this is apparently due to higher nutrient concentrations at these stations and is unrelated to CNS operation. Tempereture and dissolved oxygen profiles for Lake Hartwell in 1974 were sory similar to the average conditions observed for the period 1965 to 1972.
- 2. The weekly dissolved oxygen monitoring program showed the lowest DO concentrations at both intake and discharge of ONS to be 3.4 mg/1, which occurred on September 19, 1974. The lowest values observed for tne Keowee Hydro Intake, Keowee Hydro tailrace, and Station 605 were 4.4 mg/1, 5.4 mg/l and 5.6 mg/1, respectively. The duration of DO conditions less than 5 mg/l for the ONS intake and discharge extended from July 25 to September 19, while this condition was recorded for only one date, September 19, at the Keowee Hydro intake.
Water discharged from ONS with low dissolved oxygen concentrations )
apparently becomes oxygene.ted within relatively small areas and time spans, and should not, therefore, appreciably affect the aquatic biota of Lake Keowee.
1.3-1 ONS 12/74
- 5. Fish population dynamics and reproduction studies are continuing to be carried out by the Southeast Reservoirs Investigations group, Fish and Wildlife Service, Department of the Interior. Progress reports of their studies are appended.
- 4. Periphyton production data indicate an increased rate of production in Lake Keowee as a whole this reporting period as compared to the same period in 1973.
- 5. The average number of phytoplankton taxa per sample increased this reporting period compared ta the period ending June 30, 1974. Green algae and diatoms wer e numerically the most abundant types throughout the sampling period. All measures of phytoplankton abundance indicated larger communities in the euphotic zone (upper waters) of the lake.
Thus, hypolimnetic intake at ONS resulted in lower concentrations of phytoplankton at the condenser cooling water intake and discharge.
This was particularly noticeable from July through August, when the lake was thermally stratified.
- 6. Zooplankton sampling showed highest standing crops in July and lowest in December. As with phytoplankton, the skimmer wall acts as a partial barrier to zooplankters entering ONS, particularly from July through September, resulting in lower standing crop densities at the ONS intake, discharge and Stations 508.5 and 504.
- 7. Benthos sampling revealed a pattern of decreasing diversity from the shallow waters (littoral zone) to deeper waters (profundal zone) in both Lake Keowee and Lake Hartwell. Mean biomass was highest in the Fall on Lake Keowee and Winter on Lake Hartwell during 1974. No detrimental thermal effects of the ONS discharge were ascertaincele during this reporting period.
- 8. Monitoring of fish impingement on the intake screens has shown that the numbers of fish impinged per inspection period varied considerably, but that an increase in the number of fish impinged can generally be attributed to an increase in the percent operating time for the associated CCW pump. Threadfin shad, which comprised about two-thirds of the identifiatic fish impinged, became increasingly prevalent in November and December as the water temperature in the intake canal decreased toward the shad's lower lethal temperature. Impingement of other specie i of fish, primarily bluegill and yellow perch, reached its maximum in July. The average weight of all fish impinged during the sampling period was 2.1 grams per fish. For this reporting period, the numbers, kinds, and sizes of fish impinged on the intake screens at ONS is not considered to have been detrimental to the fishery re-sources of Lake Keowee.
No fish eggs or larvae were collected in samples taken to monitor entrainment of same.
1.3-2 ONS 12/74
- 9. Phytoplankton entrainment studies revealed that species _omposition, densities, algal biovolumes and chlorophyll a concentrations remained constant through the cooling water system of ONS in the presence of AT's of 10 C, 8.9 C and 0 C. Carbon assimilation rates of entrained phytoplankton in intake water followed no general pattern when exposed to thermal elevations in incubation chambers of 10 C, 5.1 C, and 6.7 C.
Intoke carbon assimilation rates are the primary influence on the rates observed in water from other points 1.n the cooling water system.
- 10. Zooplankton entrainment studies revealed that the number of zooplankton species found in the intake compared to the discharge of ONS was similar for each sample period. In July, when the lake was strongly s; ratified, the skimmer wall of ONS acted as a partial barrier to large numbers of zooplankton, excluding them from the intake canal and reducing the number of organisms subjected to entrainment through the ONS cooling water system. For the reporting period, corrected percent motilities were calculated which ranged from 64% to greater than 100%. The data indicate that zooplankton mortalities were primari1; due to mechanical rather than thermal effects of condenser passage.
- 11. Two successful plume mapping surveys were conducted; one in September and one in November. In September, thermal effects were discernable at depths up to 8 m and at distances up to 1,200 m from the ONS dis-charge structure. In November, thermal plume effects were discernable at depths up to 16 m and at distances up to 915 m from the ONS discharge structure.
Dissolved oxygen (DO) variability due to the ONS discharge was evident at depths up to 9 m and distances up to 1,200 m from the discharge structure in September. Variability of DO in November was so slight that the discharge plume could not be mapped using this parameter alone. For both dates and both parameters there was evidence of considerable mixing and dilution of discharge water by lake water in the immediate vicinity of the discharge structure.
- 12. Monitoring by SERI fisheries biologists detected no gas bubble disease in any Lake Keowee fishes this reporting period. Supersaturation of nitrogen, attributable to ONS operation, was found near the ONS dis-charge in November and December, 1974. The highest _value reported was 117% at Station 504 in December.
More detailed descriptions of the programs, their methods and materials, results and discussions, and summaries and conclusions are presented in the pertinent sections.

1.3.1 WATER QUALITY Specification: A. Synoptic water quality surveys at nine (9) sampling sta-tions on Lake Keowee, four (4) stations on Lake Hartwell, and a station on the Keovee River between the lakes shall be conducted. Sampling locations are shown on Fig. 1.3-1 and Fig. 1.3-2, and required sampling parameters are listed in Table 1.3-1.
Temperature and dissolved oxygen measurements shall be made at ten (10) foot intervals from a one (1) foot depth to the bottom for all lake samples. BOD measurements on Lake Keowee shall be taken at one (1) foot, ten (10) feet, and bottom depths. BOD measurements on Lake Hartwell shall be made on samples which are a composite of water from one (1) foot depth, mid-depth, and bottom depths. All other specified parameters shall be measured at a minimum of 4 three (3) depths for each lake sampling station. At sam-pling Station 605 (Fig.1.3-2), the Keowee River shall be sampled from mid-depth.
I. INTRODUCTION A discussion of the importance of a synoptic water quality program has been presented (Duke Power Company,1973).
II. METHODS AND MATERIALS Current analytical methodologies, references, preservation techniques, detection limits, and reporting units used in obtaining data for Lakes Keowee and Hartwell are presented in Tables 1.3.1-1 and 1.3.1-2.
III. RESULTS AND DISCUSSION Tabulated water chemistry data are presented in Appendix A. Composite codes used in depth columns have been given (Duke Power Company,1974).
A computer contouring program was used to generate Figures 1.3.1-1 i through 1.3.1-54. The minimum, average, and maximum was calculated for each parameter at each station during the year 1974 by combining tiie values obta'ined for all depths and all sampling periods. This dctt is presented in Table 1.3.1-3.
Lake Keowee l Temperature isopleths for July through December 1974, are shown in Tigures 1.3.1-1 through 1.3.1-6. Monthly average air temperatures for the Green-ville-Spartanburg area for 1972, 1973, and 1974 are shown in Table 1.3.1-4.
The 1973-74 winter was mild and consequently hypolimnetic water tempera-tures did not reach normal lows. However, the lake was strongly stratified by July. During July through September a surface to bottom differential of 12 C existed. Stratification continued through November. Most of Lake Keowee was destratified by mid-December. Temperatures above ambient were not observed around Station 508.0 (discharge cove) during the months of 1.3.1-1 ONS 12/74
July through October. Discharge water temperatures were often lower than ambient surface water temperatures during this period. Decreased volumes of hypolimnetic waters were noticed in the Little River Arm of Lake Keowee during July through October compared to the Keowee River Arm, probably caused by the use of hypolimnetic water for condenser cooling.
Dissolved oxygen isopleths for July through December 1974, are presented in Figures 1.3.1-7 through 1.3.1-12. Postulated effecta of discharging heated hypolimnetic water on dissolved oxygen concentration are: lowering solubility, diluting epilimnetic water with water of lower dissolved oxygen concentration, diluting epilimnetic water with water of a higher oxygen demand, and changing the reaeration coefficient (Parket and Krenkel, 1969).
These effects are usually greater during the summer because of increased surface temperatures and summer stratification. Lower than ambient dis-
~
solved oxygen concentrationa in the vicinity of the discharge cove were only observed in August and September. Dissolved oxygen concentration remained isochemical at Station 508.0, 3.6 mg/l was the lowest concentra-tion observed during the synoptic survey.
Isopleths of pH (Figures 1.3.1-13 through 1.3.1-18) ranging from 5.6 to 7.5, indicate Lake Keowee is slightly acidic. The pH was generally lower in the Keowee River Arm of the lake as noticed by the vertical stratifi-cation in the isopleths. Higher values, 7.0 to 7.5, occurred at Stations 500.0 and 501.0 during July and August. These higher values were probably due to photosynthetic assimilation. This conclusion is supported by the supersaturation of dissolved oxygen occurring at the same place and time (Appendix A). The reason for the increased photosynthetic activity is probably increased nutrient concentrations associated with organic waste of sanitary origin (Duke Power Company,1973, Appendix B). Higher phyto-plankton standing. crops were also noticed at Station 500.0 during August (Table 1.3.4-2).
Turbidity isopleths are presented in Figures 1.3.1-19 through 1.3.1-24.
Lake Keowee is a very clear lake with turbidity values usually less than 5 JTU in the epilimnion and metalimnion. Higher values were observed in the hypolimnion of the Keowee River Arm during July and August but had settled out by September. Station 508.0 generally had similar turbidity readings to the other stations.
Conductivity isopleths are presented in Figures 1.3.1-25 through 1.3.1-30.
The readings were generally less than 25 pmhos. Slightly higher concen-trations were observed in the Little River Arm than in the Keowee River Arm. Conductivity values increased with depth during the months of July through November. Little difference was observed between stations and no effect of ONS was seen on conductivity values.
Lake Keowee has a very low nutrient concentration. The concentration of ortho-phosphate was rarely detectable and had an average concentration of 0.012 mg/1-P for this six month period. The average concentrations of nitrite plus nitrate nitrogen was only 0.132 mg/1-N for 1974 in Lake Keowee. Epilimnetic ammonia concentrations were generally less than 0.10 mg/1-N. Higher ammonia concentrations (0.10 to 1.2 mg/1-N) were observed in the hypolimnion of Lake Keowee during the months of July through October. ,
1.3.1-2 ONS 12/74
l i
Ammonia nitrogen for the most part arises from the breakdown of amino acids in the water and ooze (Ruttner,1963) . Under aerobic conditions it is oxidized to nitrate and can be used as a nitrogen source for phyto-plankton (Toetz,1971) . When summer stratification occurs and dissolved oxygen is depleted, ammonia concentration increases in the hypolimnion of Lake Keowee. August samples showed higher values (between 0.13 and 1.14 mg/1) in epilimnetic waters at Stations 503.0, 504.0, 505.0, 508.0, and 508.5 (Figure 1.3.1-32), but these higher values may be attributable to contamination in the autoanalyzer systems. With the exception of the August samples, increased ammonia concentrations were not evident in the vicinity of the ONS discharge.
Lake Keowee can be classified as a sof t water lake with calculated hard-ness values generally less than 10 mg/1. Silica (orthosilicate) was the major cation present followed by sodium, calcium, potassium, and magne- '
sium, respectively. Levels of sodium, calcium, potassium, and magnesium did not show significant stratification and their mean values listed in Table 1.3.1-3 reflect the concentration present at all depths. Silica isopleths are presented in Figures 1.3.1-37 through 1.3.1-42. Silica is used by diatoms as an essential material for formation of the siliceous frustule of diatoms. Little stratification was observed in silica con-centration. Iron and manganese play a major role in determining the effects of hypolimnetic withdrawal because of their abrupt solubility change under anoxic conditions. This solubility change can clearly be seen in Figures 1.3.1-43 through 1.3.1-54. Only in July was there any noticeable increase in concentration of iron at Station 508.0 (Figure 1.3.1-43); manganese concentrations at 508.0 were never noticeably increased.
Lake Hartwell Temperature and dissolved oxygen profiles for Stations 601 through 604 are shown in Figures 1.3.1-55 through 1.3.1-59. The lake was strongly strat-ified during the months of July, August, and September. Maximum tempera-tures occurred in July at which time a 13.5 C differential existed between surface and bottom waters at Station 601. The thermal cycle observed in 1974 was very similar to the average of previous years (Figures 1.3.1-55 through 1.3.1-59). Isothermal conditions existed from October through December.
Anoxic conditions existed in the hypolimnion of Stations 601 and 602 during July and August. Dissolved oxygen gradients are caused by inade-quate mixing which allows photosynthesis or oxygen demand to exceed the equilibration rate with the atmosphere. The average concentration of dissolved oxygen in hypolimnetic waters of Stations 601 and 602 was less than 0.5 mg/l during July and August (Figure 1.3.1-59). These anoxic conditions occurred in most previous years and cannot be attributed to the operation of ONS. Supersaturation of dissolved oxygen (100-120%) occurred in the epilimnion at most stations during July. This supersaturation was probably the result of photosynthetic activity. This conclusion is sup-ported by the increased pH readings in July.
O 1.3.1-3 C M ._JL2 L U
4 Lake Hartwell can be classified as a sof t water lake, calculated hardness was generally less than 10 mg/1. It generally had low alkalinity with an average of 12.? mg/l as CACO 3 for this six month period. The average con-centratien of calcium, magnesium, iron, and manganese was 2.12, 0.85, 0.64, and 0.18 mg/1, respectively. As was seen in Lake Keowee, calcium and l
magnesium remained fairly constant, not varing temporarily or spatially.
The concentration of iron and manganese increased with depth during summer stratification due to their increased solubility in anoxic waters.
IV. SUKMARY MD CONCLUSIONS Uate themistry data from July through December 1974, are compiled in Appeur.1x A. Higher waier temperatures were observed in the discharge cove during November and December. Decreased volumes of hypolimnetic waters were noticed in the Little River Arm of Lake Keowee during July through October compared to the Keowee River Arm, probably caused by the use of hypolimnetic water for condenser cooling. Lower than ambient dissolved oxygen concentrations in the vicinity of the discharge cove were only observed in August and September. Consistent with data presented in the three previous semi-annual reports, higher pH values and oxygen saturation was observed at Stations 500.0 and 501.0 varing July and August.
Low dissolved oxygen concentration in the hypolimnion of Lake Hartwell can not be attributad to the operation of ONS.

1.3.1 WATER QUALITY Specification: A (continued)
Dissolved oxygen will also be measured weekly from May through November at three locations: (1) the Oconee discharge, (2) the lake surface (one (1} foot deep) at the Keowee intake structure, and (3) the Keowee tail-race during hydroelectric plant operation.
I. INIRODUCTION ONS utilizes a hypolimnetic withdrawal (discussed previously, Duke Power Company, 1973b) from Lake Keowee for its condenser cooling water. During periods of lake stratification (May through November) this withdrawal of cool bottom water low in dissolved oxygen (DO) 4 and its subsequent discharge to the surface of Lake Keowee is the basis for the above Specification.
II. METHODS AN11 MATERIALS Dissolved oxygen content and temperature levels were monitored weekly (duplicate samples) in Lake Keowee and the Keowee River from the following facility structures: ONS intake and discharge, Keowee Hydro Station intake and tailrace, and the S. C. Highway ,
//183 Bridge (Station 605).
The methods and materials have been described previously (Duke Power Company, 1973a) was employed for DO analysis. Station biologists performed the sampling and analyses.
III. RESULTS AND DISCUSSION -
The results of the weekly D0 monitoring program plus the associated percent saturation values and temperature measurements are presented in Table 1.3.1-5. Figure 1.3.1-60 illustrates the dissolved oxygen values for the five monitoring stations. Dissolved oxygen values for the ONS intake ranged from a low of 3.4 mg/l on September 19 to a high of 8.3 mg/l on November 28. DO values for the ONS discharge ranged from a low of 3.4 mg/l also on September 19 to a high of 8.2 mg/l on November 21. The lowest value recorded at the Keowee Hydro intake was 4.4 mg/l on September 19. The lowest value of dissolved oxygen recorded for the Keowee Hydro tailrace and Station 605 was 5.4 mg/l on September 12 and 5.6 mg/l on September 19, respectively.
The duration of DO conditions less than 5 mg/l for the ONS intake and discharge extended from July 25 to September 19. A low DO condition at the Keowee Hydro intake was recorded for only one date, September 19.

SUMMARY
AND CONCLUSIONS !
A general increase in dissolved oxygen values can be attributed to the following: (1) ONS discharge water mixing with lake water in the discharge cove; (2) aeration in the discharge cove; and (3) mixing and arcation in the Keowee Hydro tailrace during the operation of the Keowee Hydro Station.
With respect to D0, the impact of a hypolimnetic withdrawal and subsequent discharge to the surface of Lake Keowee is restricted to the immediate area of the ONS discharge cove. The short duration of DO conditions less than 5 mg/l and the relatively small area of
- the lake affected is not expected to appreciably effect the aquatic 4
biota of Lake Keowee.

1.3.2 FISH - POM L\ TION DYNAMICS AND REPRODUCTION Specification: A. Comparisons shall be made of the data obtained by sys-tematic sampling of fishes using nets, electrofishing, and rotenone at suitable locations both within and essentially out of the influence of the effluent.
A i Significant changes in the composition, a'oundance, and growth of the major fishes in various areas of Lake Keowee shall be identified and the factors which cause change defined especially those relating to the effluent from Oconee Nuclear Station.
I. INTRODUCTION A discussion of the effects of power plant operation on the population dynamics of fishes was presented in the Oconee Nuclear Station' Semi-Annual Report for the period ending June 30, 1973 (Duke Power Company, 1973). These studies are being performed by the Southeast Reservoir Investigations (SERI), Bureau of Sport Fisheries and Wildlife, located in Clemson, South Carolina, i
II. METHODS AND MATERIALS Methods and materials used for fisheries research in connection with the operation of ONS have been summarized in the previous semi-annual report for the period ending June 30, 1974 (Duke Power Company, 1974). This
- program has continued through December 31, 1974.
III. RESULTS AND DISCUSSION 1
Data necessary to characterize the dynamics of fish populations of Lake j Keowee have been collected using seines, frame trawls, gill nets and i electrofishing gear. A discussion of these data is provided in SERI Reports for the periods July 1, 1974 - September 30, 1974, and October 1, 1974 - December 31, 1974 (Appendices B and C). l l
SERI reports that during July the water temperature in the discharge cove '
was approximately 4.5 C cooler than the ambient surface reservoir temper-ature. In August the discharge cove surface temperature was approximately j 1.5 C cooler, but in September the discharge cove was about 1.5 C warmer than ambient surface reservoir temperature. These low discharge temper-atures, relative to ambient, were due to the hypolimnetic cooling water source and inconsistent plant operation. Under these conditions the effects of the affluents from ONS on the fish populations of Lake Keowee l have not been apparent.
Sample sizes of threadfin shad have increased continually since this species was stocked in February 1974. Otherwise, adult fish sampling using gill nets and electrofishing gear has not indicated overall char.ges in species
, composition from 1973 to 1974. Relative species abundances, as indicated 1
1.3.2-1 '
i ONS 12/74
_~. _ _ __ _ . -- __
t by gill net data, have varied from 1973 to 1974 in some cases; however, this was likely due to sampling error. Rotenone data for 1974 indicate j standing crops were similar to those reported for the previous two years, i
l Age and growth studies of major fish species of Lake Keowee have not been l completed. The growth characteristics of fishes depend, at least in part, on population densities and food availability. Keowee is still in early j stages of ecological development and these factors can be expected to vary considerably during the first several years after the reservoir was filled.
The recent introduction of threadfin shad is also recognized as an addi-tional variable af fecting the growth of piscivorous species.
IV.
SUMMARY
AND CONCLUSIONS ONS had not reached full generating capacity and discharge temperatures
- were low. Significant changes in composition.. abundance and growth of l major fish species has not occurred as a result of the ONS discharge.
j Abundance of threadfin shad increased since they were introduced in February 1974.

1.3.2 FISH - POPULATION DYNAMICS AND REPRODUCTION Specification: B. The reproduction of four (4) indicator species (large-mouth bass, black crappie, yellow perch, and bluegill) representative of the fish species in Lake Keowee shall be characterized by determining the environmental re-quirements for reproduction. Pertinent data collected from other studies shall be utilized and results and ob-servations obtained for Lake Keowee shall be compared to those previously published.
Spawning data for Lake Keowee shall be collected by direct observation and the use of ichthyoplankton trawls.
The sampling procedures, periods, and intensity related to Specifications A and B above will be based on those established by the Southeast Reservoir Investigations team of the Bureau of Sport Fisheries and Wildlife, Department of the Interior.
I. INTRODUCTION A discussion of the effects of power plant operation on the population dynamics of fishes was presented in the Oconee Nuclear Station Semi-Annual Report for the period ending June 30, 1973 (Duke Power Company, 1973).
II. METHODS AND MATERIALS i
1 The methods and materials used in studying the reproduction of Lake Keowee fishes have been previously described (Duke Power Company, 1974). This program has continued without change through December 31, 1974.
l' III. RESULTS AND DISCUSSION Life history studies have continued on four indicator species represent-ative of the species in Lake Keowee. These are: largemouth bass, black crappie, bluegill, and yellow perch.
Life history studies have been divided into three distinct parameters for each species. These are: (1) Age and growth, (2) Reproduction and fecun-l dity, and (3) Food habits. Three study areas on Lake Keowee have been selected as sampling locations for life history data. These areas are:
(1) Pump back, (2) ONS discharge, and (3) A control located near Watergate Marina.
Collection of data on largemouth bass, black crappie, bluegill and yellow perch, before and after heated effluent discharge into Keovee Reservoir is being continued. Gonads have been collected and preserved from speci-mens since the 1973 field season began. These will be used to determine
, fecundity of females and seasonal maturity index changes in males and females.
1.3.2-3 ONS 12/74
Identification, counting, and measuring of fishes collected with the frame trawl at five areas in Keowee Reservoir during 1974 was completed.
Catches of sunfish and yellow perch were 50% lower in 1974 than in 1973 and catches of black crappie declined 26% over the same period. Thread-fin shad were not collected in 1,73, but 3,645 shad were collected in 1974 with 80% taken from the area immediately below Jocassee Dam. Large-mouth bass larvae were not represent d in frame trawl samples.
IV. SLT!ARY AND CONCLUSIONS Complete data on the reproduction of largemouth bass, black crappie, yellow perch, and bluegill is not yet available. Larval sunfish, yellow perch, and black crappie were collected in fewer numbers in 1974 than in 1973. Larval largemouth bass have not been collected.

1.3.3 PERIPHYTON Specification: Duplicate artificial substrates (plexiglass slides) shall be held in racks and submerged at a depth of five feet at three general locations in the lake (Stations 502, 504, and a station in the discharge area) that may be influ-enced by the plant discharge, and at two control locations in the lake (Station 501 and 506) that shall be essentially out of the influence of the plant discharge. Dry and ash-free weights of each sample shall be determined so that comparisons can be made of the relative productivity values between the different stations.
I. INTRODUCTION Periphyton is presently being studied as an indicator of water quality.
Organic accumulation is being measured in this study at Stations 500, 501, 502, 508, 504, and 506. A general discussion of the concepts in-volved in this study may be found in Oconee Nuclear Station Semi-Annual Report for the period ending June 30, 1973 (Duke Power Company, 1973a).
II. METHODS AND MATERIALS A discussion of the materials and methods involved in this study may be j found in the ONS Semi-Annual Report for the period ending June 30, 1973 (Duke Power Company, 1973a).
Since August, 1974, a change in the exposure period was made from the previous approximately eight week period to a period of approximately 30 days. Chlorophyll a and pheophytin data were not recorded during this period because the nature of the analysis introduced substantial error and the results were variable.
III. RESULTS AND DISCUSSION Periphyton production data for the period ending in November 1974, are listed in Table 1.3.3-1. Due to a change in personnel and a resulting time delay, the December 1974 data are not listed in this report but will be found in the report for the six month period ending June 30, 1975.
Compared with data for the same period ending December 31, 1973 (Duke Power Company, 1973b), an increase in the productivity of periphyton has occurred.or is occurring. This trend may be observed at all stations except 508 which exhibits slight deviation from the previous year's data.
IV. SUM >!ARY AND CONCLUSIONS Lake Keowee productivity has increased over the same period for 1973 as indicated by the periphyton accumulation data. This increase has been large enough to warrant a decrease of exposure period in the sampling procedure. However, the increase in the accumulation rate was too small j to make the general conclusion that this is a long term trend. It is impossible at this time to determine the role, if any, that ONS has had in this process.

l.3.4 PHYTOPLANKTON - ZOOPLANKTON RECEIVING WATER STUDY Specification: Bimonthly sampling (6 times /yr.) shall be done at stations 500, 503, 505, 506, intake, and at two points along the centerline of the Keowee River arm of Lake Keowee. The geographical location of these latter two stations shall be determined at each sampling period and shall represent the points at which the plume surface temperature is 0.9 and 0.5 of the temperature excess of the discharge over ambient sur-face temperature. For the purpose of this study, " ambient surface temperature" shall be defined as the surface temper-ature at Station 500 as measured on the day of the plankton sampling.
Both whole water samples and samples concentrated using a plankton net will be collected. The sampling at stations affected by the discharge shall consist of samples'taken at water depths, both affected and not affected by the plume.
At the control stations, samples will also be taken at these corresponding depths.
I. INTRODUCTION A discussion of the importance of phytoplankton and zooplankton with re-spect to thermal effects has been presented (Duke Power Company, 1973a).
II. METHODS AND MATERIALS The methods and materials have been described previously (Duke Power Company, 1973a, 1973b, 1974). Changes are listed below.
Phytoplankton Standing Crops. The expression of algal standing crops has been changed from units per liter to units per milliliter. This provides consistency with population analysis trends found in other scientific lit-erat >;ce. Biovolume measurements were also revised from mm3 per liter to uc' per milliliter; biovolumes presented in previous semi-annual reports would have to be multiplied by 106 to obtain values in um3 per milliliter.
Zooplankton Standing Crops. Beginning in August 1974, zooplankton samples were collected by vertically towing a 0.5 m (net mouth diameter) #20 mesh plankton net and bucket. A General Oceanics flow meter is suspended in the mouth of the net for determining the volume of water filtered. Deter-mination of actual distance of the water column sampled is calculated by using Figure 1.3.4-1 which converts flow meter counts per second to water velocity. Water velocity through the net multiplied by seconds of net tow provides the total distance in centimeters of the water column sampled (h). l Water volume filtered is then determined by the formula for a cylinder: l V = rr 2 h where: V = volume filtered, n = 3.1416, r = radius of net mouth (25 cm),
h = actual distance of column sampled in centimeters.
The diameter of the net reduces the ef fects of horizontal zooplankton patch-iness and avoidance of the sampling device by the organisms (Donald Wade,
. personal communication).

1.3.4-1 ONS 12/74
Duplicate sampling from 10 m to surface at selected stations (500, 502, 503, 504, 505, and 508) was initiated in October 1974, to provide more statistically valid data.
Beginning in October 1974, L.-Phenyl-ephrine Hydrochloride (Neo-synephrine) was added to the samples as a relaxing agent prior to the addition of 4%
formalin preservative. This technique reduces identification problems en-countered with some of the rotifers by preserving them in a relaxed state, and may also prevent copepod egg sac loss and cladocera carapace ballooning.
Sampling Procedure As proposed in the previous semi-annual report (Duke Power Company, 1974),
monthly collections were obtained at all stations beginning.in July.
In September 1974, an additional sampling station (504) was included near the Keowee Hydro-intake. Like Station 508.5, it was established to pro-vide information on planktonic communities in the near-discharge area of ONS.
III. RESULTS AND DISCUSSION Phytoplankton: Standing Crops. Whole water samples were collected at monthly intervals from July through December.to determine phytoplankton composition, densities, and biovolume. Sampling depths are presented in Table 1.3.4-75.
One hundred forty-five new species of algae were recorded during this period.
Ten algal classes have representative species noted from Lake Keowee col-lections (Table 1.3.4-1). New species by class are as follows: 73 green i
species (Chlorophyceae); 19 blue greens (Myxophyceae); 18 yellow browns (Chrysephyceae); 15 diatoms (Bc:111ariophyceae); 10 dinofingellates (Dinophyceae); four euglenoids (Euglenophyceae); and three cryptophytes (Cryptophyceae). Haptophyceae with one species and the Chloromonadophyceae with two species were the two new classes reported from Lake Keowee. A total of 315 algal species have been tallied to date not including some taxonomic changes from prior checklists.
Phytoplankton community standing crops from the period July-Decemb'er, 1974, are summarized in Table 1.3.4-2. . Maximum mean number of species from the euphotic zone composites (EZC) occurred in September (37) while the highest mean number of species in the lower sample depth (LSD) was observed in November (30). December collections provided the fewest numer of species per sample in both EZC and LSD water with 24 and 22, respectively.
A pattern of higher couats and biovolumes occurred in EZC samples than in LSD collections (Table 1.3.4-2). Monthly mean densities reached a maximum in September (871/ml) while biovolume attained the highest mean for the period in October (46.49 x 10" um3 /ml). Definite vertical differences in cell counts and biovolumes were evident between July and October. Fall overturn in Lake Keowee apparently created a more uniform vertical distri-bution of phytoplankton after October based on taxa abundance, densities, and biovolumes.

- Comparisons were made between the open lake stations (500, 502, 503, 505,
- and 506) and stations in the area of the ONS discharge (504, 508, and 508.5) (Table-l.3.4-2). These comparisons were made on the basis of mean number of taxa, mean densities and mean biovolumes found in the EZC only.
. The same comparisons were made between the intake station (509) and those l stations in the area of the ONS discharge (Table 1.3.4-2).
The open lake stations (OLS) showed a greater mean number of taxa than the discharge area stations (DAS) in July (OLS = 33, DAS = 30), August (OLS = 37, DAS = 31), September (OLS = 39, DAS = 29) and October (OLS = 35, DAS = 30). The DAS showed a greater mean number of taxa in November (DAS =
28, OLS = 27) and December (DAS = 25, OLS = 24).
t a
Greater mean densities were noted for the OLS compared to the DAS in July (OLS = 491/ml, DAS = 294/ml), August (OLS = 547/ml, DAS = 457/ml), September
] (OLS = ll59/m1, DAS = 454/ml), October (0LS = 554/ml, DAS = 359/ml), November (OLS = 464/ml, DAS = 371/ml), and December (OLS = 210/ml, DAS = 164/ml).
Mean biovalumes (x 104 pm3 /ml) for the OLS vere higher in August (OLS = 29.55, DAS = 29.12), September (OLS = 58.58, DAS = 13.00), October (OLS = 51.48, DAS = 25.14), November (OLS = 18.54, DAS = 16.67), and December (OLS = 14.04, DAS = 7.45) than the DAS. The DAS showed a slightly greater mean biovolume in July (DAS = 14.40, OLS = 13.75).
The comparison between the intake station (IS) and the DAS showed a greater i mean number of taxa occurring at the IS in August (IS = 33, DAS = 31) ,
j October (IS = 39, DAS = 30), and November (IS = 41, DAS = 28). The DAS showed a greater mean number of taxa than the IS in July (DAS = 30, IS = 24),
, September (DAS = 29, IS = 27), and December (DAS = 25, IS = 21).
J Mean densities were greater at the IS than at the DAS in December only (IS =
213/ml, DAS = 164/ml). The DAS showed greater mean density values in July (DAS = 294/ml,.IS = 141/ml), August (DAS = 456/ml, IS = 206/ml), September (DAS = 454/ml, IS = 425/ml), October (DAS = 359/ml, IS = 347/ml) and November (DAS = 371/m1, IS = 325/ml).
Mean biovolumes (x 10 4 um3 /ml) noted at the IS exceeded those at the DAS in July (IS = 26.77, DAS = 14.40), September (IS = 16.50, DAS = 13.00) and December (IS = 13.07, DAS = 7.+5). The mean biovolume among the DAS was greater than the mean biovolume at the IS in August (DAS = 29.12, IS = 11.44),
October (DAS = 25.14, IS = 19.12), and November (DAS = 16.67, IS = 16.19) .
Comparison of Station 504 standing crops with those of Station 508.5 sug-l gests that sufficient similarity of the phytoplankton community structure
- exists between the two stations to justify discontinuing further collection at 504.
In terms of percent composition by number, the Chlorophyceae occurred most frequently at the sampling stations in Lake Keowee (Tables 1.3.4-3 through 1.3.4-66). The Dinophyceae and Bacillariophyceae consistently comprised
, the major percentage cf algal biovolume for all study dates. Phytoplankton l species which contributed the largest percentage of total biovolume on a monthly. basis were: three species of Peridinium in July; Cryptemonas ovata and Peridinium spp. in August and September; Peridinium spp. and two species -

1 of Rhizosolenia in October; and R. spp. in November and December. The Peridinium spp. and Rhizosolenia spp. groups are markedly larger in bio-volume than other algal species but contributed a low number of cells per sample except in December when R. spp. made up a major portion of the numbers.
, A yearly summary of standing crop results indicates a minimum mean number of taxa were observed in EZC samples in January and a maximum mean number of taxa occurred in September. LSD samples also showed the lowest taxa number in January but a peak in November. Mean densities in euphotic zone samples were lowest in January and highest in September while algal abundance in LSD samples was highest in May and lowest in January. Algal biovolume reached a maximum mean value in EZC samples during October and a minimum biovolume occurred in January. The lower sample depth collections produced lowest mean biovolumes during August and maximum mean biovolumes occurred in May. The additional collections at Stations 510 and 511 con-3 tributed to higher mean density and biovolume estimates.
Phytoplankton: Chlorophyll a. Concentrations of chlorophyll a at sclected points in Lake Keowee were investigated in conjunction with standing crop estimates. Mean chlorophyll concentrations in the EZC and LSD collections
! showed a gradual monthly decline from July to December (Table 1.3.4-67).
l The means ranged from 3.16 (July) to 0.59 (December) mg/m3 in the EZC sam- '
ples while LSD samples ranged from 1.13 (July) to 0.48 (December) mg/m3.
Mean concentrations of chlorophyll g( in EZC samples from discharge area stations (508, 508.5, and 504) were lower than the control station (506) concentrations from July through December. The reduced pigment concen-trations observed in discharge area EZC samples are directly related to the low intake (509) concentrations. Chlorophyll jt levels in LSD samples from Station 502 (outside the skimmer wall) were similar to levels which occurred at 509 but were lower than EZC pigment concentrations at 502.
1
, Vertical differences in chlorophyll it concentrations were usually evident
! at all open lake stations with maximum levels in the euphotic zone and minimums near bottom. Stations 510 and 511 consistently averaged more chlorophyll gt in EZC samples than other stations.
Seasonal trends in EZC and LSD chlorophyll jt concentrations from Lake Keowee indicate that maximum mena concentrations occurred in May, while the lowest pigment concentrations for the year were noted during December.
Zoopinnkton. The study period (July through December 1974) yielded 22 additional zooplankton species to the previcus species list (Table 1.3.4-68) .
These additional species probably.resulted from the new sampling method, more intensive sampling (monthly and duplicate), and improved saeple pres-ervation methods. Of the 61 zooplankton species found this reporting period, 6 were copepods, 16 were cladocerans, and 39 were rotifers.
Tables 1.3.4-69 through 1.3.4-74 list the standing crop values in number per liter (no./1) for each organism observed at each station for each sampling month.

1.3.4-4 ONS 12/74
Standing crops were highest in July for the six month sampling period (Figure 1.3.4-2). This pulse averaged approximately 53 no./l for the 10 m to surface samples collected at the following designated stations:
500 (lake control); 502, 508, 508.5, and 504 (those stations in the immediate vicinity of and potentially affected by ONS operations). The intake (Station 509) standing crop was only 4 no./l compared to the 56 no./l standing crop value for Station 502 which is located just lake-side of the skimmer wall. Therefore, the low intake standing crop value is attributable primarily to the exclusion of organisms by the skimmer wall. It should be noted that the lake was thermally stratified in July.
The mean zooplankton density at designated stations was comprised of rotifers (58%), copepods (32%), and cladocerans (10%). Dominance was shared by Keratella cochlearis, Kellicottia bostoniensis, and Ptygura libera for the rotifer community (Table 1.3.4-69). Juveniles, particularly nauplii, were the dominant copepod life stage whereas Diaptomus mississippiensis was the most abundant adult copepod. Bosmina coregoni was tre most prevalent cladoceran (Figure 1.3.4-3).
Standing crops in August averaged 20 no./l (Figure 1.3.4-3). The intake station field data were lost for August; therefore, intake standing crop data are not available. The zooplankton population at the designated stations consisted of copepods (56%), rotifers (23%), and cladocerans (21%).
Again, immatures, particularly nauplii, were the most abundant copepod life stage. Tropocyclops prasinus was the dominant adult copepod. Bosmina coregoni was the most abundant cladoceran and Keratella crassa, Kellicottia i
bostoniensis, and Conochilus unicornis were the prevalent rotifers.
September (Figure 1.4.3-4) mean standing crops for the designated stations increased to 48 no./1. As in July, standing crop values in the intake were lower (18 no./1) than standing crop values for each of the selected lake stations. The zooplankton assemblage was comprised of copepods (44%),
rotifers (33%), and cladocerans (23%) for the selected stations. Nauplii and cyclopoid copepodids were the most abundant copepod life stage.
Diaptomus mississippiensis and Tropocyclops prasinus were the prominent adult copepods. Bosmina coregoni was the primary cladoceran species and Keratella crassa, Kellicottia bostoniensis, and Trichocerca cylindrica were the most prevalent rotifers in September (Table 1.3.4-71).
October standing crops were relatively low with a mean of only 4 no./l at the designated stations (Figure 1.3.4-5). The intake standing crop values were numerically similar to the standing crop values at the designated lake stations probably due to decreased lake stratification and increased .
zooplankton vertical migration. The zooplankton community was composed of l rotifers (70%), cladocerans (20%), and copepods (10%). Keratella crassa
, and Hexarthra mira were-the prevalent rotifers while Bosmina coregoni was the dominant cladoceran in October. Nauplii were the most abundant l copepod life stage. Diaptomus mississippiensis was the prevalent adult copepod (Table 1.3.4-72).
An estimated mean density of 18 no./l at the designated lake stations was
! present in November (Figure 1.3.4-6). The intake standing crops were
- numerically comparable to those of the designated lake stations, probably due to the nearly isothermal condition of the lake-(Figure 1.3.1-5). The i
1.3.4-5 ONS 12/74
zcoplankton community was composed of rotifers (72%), cladocerans (13%),
and copepods (12%). The most abundant cladoceran was Bosmina coregoni whereas the nauplii life stage dominated the copepods. The prevalent adult copepod was Diaptomus mississippiensis. The prevalent rotifers included Kellicottia bostoni isis, Hexarthra mira, and Conochilus unicornis (Table 1.3.4-73).
In December, standing crops were substantially less than in the previous months. The average standing crop value for the designated lake stations was only 1 no./1 (Figure 1.3.4-6). Of the zooplankton enumerated, 48%
were cladocerans, 45% were rotifers, and 7% were copepods. Bosmina coregoni was the dominant cladoceran, and nauplit were the prevalent I
copepod life stage. Adult copepod numbers were too small to warrant dis-cussion concerning numerical dominance. Kellicottia bostoniensis was the dominant rotifer (Table 1.3.4-74).
During this reporting period, the estimated zooplankton standing crops in the 10 m to surface tows averaged 20.7 no./l at Stations 500, 502, 503, 505, and 506, whereas Stations 508, 508.5, and 504 averaged 7.3 no./l.
IV. SUmfARY AND CONCLUSIONS Phytoplankton 4
Standing crops of phytoplankton in Lake Keowee were examined at monthly intervals from July through December. During that period, 145 new species j of algae were added to the checklist for June 1974. Representative species from two new algal classes were reported. The average number of taxa per ,
sample increased this period compared to the period ending June 1974. J Algal densities and biovolumes were usually highest in EZC collections at Stations 500, 510, and 511. Green algae and diatoms were numerically most abundant throughout the sampling period. Dinoflagellates and diatoms com-prised a major portion of the biovolume in most samples. Vertical differ-ences in phytoplankton standing crops and chlorophyll a occurred at most stations with typically higher values in EZC samples. Intake EZC samples contained lower algal densities than open lake stations in all months during the sampling period. Discharge EZC samples contained higher algal densities than intake samples during all months er. cept December, when the difference was negligible (3 units /ml). The similarity in densities in discharge area samples and intake samples during December is related to the reduced vertical stratification of algal densities at the skimmer wall station (502) when compared to other months. Algal densities at the discharge area stations were intermediate between the lower densities at the intake and the higher
. densities at the open lake stations. Mean algal biovolume in EZC samples was greatest at open lake stations compared to discharge area stations in all months except July. Open lake chlorophyll a concentrations in EZC i
samples were lowest at stations in the area of the ONS effluent. These reduced concentrations were directly related to the low intake pigment concentrations which were similar to near-bottom chlorophyll concentrations at Station 502.
f 1.3.4-6 ONS 12/74
Zooplankton The study period yielded 22 additional zooplankton species to the previous species list, attributable primarily to more intensive sampling (monthly and duplicate), improved sampling gear, and sample preservation methods.
The mean total zooplankton standing crops for the designated stations reached a high in July and a low in December. During months of lake stratification, the intake standing crop values tended to be lower than the values for lake stations (particularly Station 502 which is just lake side of the skimmer wall). Therefore, the skimmer wall functions as a partial barrier to zooplankters during lake stratification. Rotifers were more abundant than cladocerans and copepods for the months of July, October, and November. Among the prevalent rotifers for the six-month period were: Kellicottia bostoniensis, Keratella crassa and K. cochlearis, i Hexarthra mira, Conochilus unicornis, and Trichocerca cylindrica. Copepods were the most dominant group in August and September. Juveniles, partic-ularly nauplii, were the most common copepod life stage for the sampling period. Prevalent adult copepod species for the sampling period were
- Diaptomus mississippiensis and Tropocyclops prasinus. Cladocerans were the numerically dominant group in December. Bosmina coregoni was the most abundant cladoceran for the sampling period. Total zooplankton standing crops at the discharge area were consistently lower than at the other lake stations for this reporting period.
For the year 1974, standing crops were highest during July and lowest in December. The numerically dominant adult organisms for the months sampled during the year included Bosmina coregoni for the cladocerans, Diaptomus mississippiensis for the copepods and Keratella crassa for the rotifers.
All the months sampled during the year, with the exception of May, indicate the skimmer wall functions as a partial barrier to zooplankton during months of lake stratification. The discrepancy in Mr could possibly be due to sampling error, since duplicate samples were not taken in May. Standing crop data for 1974 indicate no discernable differences in total zooplankton no./l between the stations in the vicinity of ONS discharge and the other lake stations.
