CHAPTER I INTRODUCTION LEGAL BACKGRDUND Under the provision of the Clean Water Act (the Act), operators of steam elec-tric pcwer generating units must comply with applicable technology-based ef-fluen* 'qttations promulgated by the Administrator of the Environmental Pro-tection Agency. These Ilmitations, Effluent Guidelines and Standards, are published at 40 CFR Part 423 In addition, compliance with effluent limita-tions calculated to achieve water quality standards is required under Section 301(b)(1)(c) of the Act. With respect to the discharge of heat, however, an exemption from any of these limitations is available if the operator can make a successful demonstration under Section 316(a) of the Act. In the State of North Carolina NPDES Permit No. NC0024392 Duke Power Company is required to submit the results of a 316(a) Demonstration for the twc units of McGuire Nu-clear Station.
McGuire Permit Recuirements McGuire Nuclear Station will discharge its condenser cooling water to Lake Norman. Therefore, it must operate in accordance with " Classifications and Water Quality Standards Applicable to Surface Waters of North Carolina,"
adopted by the North Carolina Environmental Management Commission under Au-thority of Article 21, Chapter 143, General Statutes of North Carolina, as amended.
Applicable sections include 15 NCAC 28.0211(c)(3)(J) which states that Class A-ll waters are "not to exceed 2.8 degrees C (5.04 degrees F) above the natur-al water temperature,and in no case to exceed .. 32 degrees C (89.6 degrees F) for lower piedmont and coastal plain waters ...."; and 15 NCAC 28.0204 which states that tests conducted to determine compliance with these standards be made "outside the limits of prescribed mixing zcnes."
On March 28, 1978, the North Carolina Department of Natural Resources and Com-munity Development Division of Environmental Management issued NPDES Permit No. NC0024392 authorizing a mixing zone shown in Figure 1-2 and described as follows:
"The facilities shall be effectively maintained and operated at all times so as to meet the temperature standards of 5'F increase above natural water temperature and a maximum of 90*F measured as 24-hour average one foot below the water surface except within a mixing zone containing an area of no more than 3,500 acres and lying upstream of the Dam and south of a line originating on the ,
west bank of N. C. Coordinates E-1,416,900, and N-633,600 and ex-tending south 70*-00' east intersecting the point of land on the eastern shore, but at no time shall the heated waste discharge increase the temperature of the waters at any point within the Lake in excess of 95*F, as of a monthly average."
The mixing zone as described above is shown in Figure 1-2.
Based on a 20 year simulation using the Ryan and Harleman cooling pond mod-el, using conservative inputs mentioned in Chapter lil, McGuire would exceed the 35*C (95*F) criterion by 0.5*C (1 F) for three-one month periods over the 20 years simulated. In no case would the 14 km2 (3500 acre) mixing :one be violated. It should be noted that the McGuire discharge temperature was com-puted at the " mouth of the pipe" and not at the confluence of the 970 m (0.6 mile) long discharge canal with Lake Norman, where the 35*C (95 F) discharge criterion will have to be met. This adds to the conservativeness of the com-putations.
The Ryan and Harleman cooling pond model is the best tool currently available for the simulation of a cooling lake such as Lake Norman. Although Duke Pow-er Company realizes there are some uncertainties associated with the mathema-tical model, II believes that limitations stipulated in NPDES Permit No.
,NC0024392 will not be violated by McGuire due to the conservative assump-tions associated with the model predictions. Nevertheless, Duke Power Com-pany is committed to operate McGuire in accordance with conditions promulgat-ed in the Permit.
I Marshall Permit Recuirements On March 3, 1976, the North Carolina Department of Natural and Economic Re-sources issued NPDES Permit No. NC0004937 for Marshall Steam Station in com-pliance with the provisions of the Federal Water Pollution Control Act. The permit limits the Marshall monthly average discharge temperature to 34.4 C (94*F) during the period July 1 to October 15 and 33.3*C (92 F) the remainder of the year. As with McGuire, the Marshall monthly average discharge tempera-ture was predicted to exceed 34.4*C (94*F) on three occasions (Table 3-4).
As stated earlier, Duke believes the Ryan and Harleman model predictions are extremely conservative and is therefore, confident the permit limitations will not be violated.
SITE LOCATION - PHYSICAL DESCRIPTION The 2360 MW electrical McGuire Nuclear Station is located approximately 27 km (17 miles) north-northwest of Charlotte, North Carolina, in Mecklenburg Coun-ty (Fig. 1-1). This site is located on the south shore of Lake Norman, which was formed in 1963 by the construction of Cowans Ford Dam. The lake was built primarily to provide a source of cooling water for steam electric facil-ities and for hydroelectric power generation. The 360 MW electrical Cowans Ford Hydroelectrical Station is approximately 900 m (1000 yd) west of the McGuire site. A submerged skimmer weir located in front of the Cowans Ford Hydroelectric Station intake allows passage of the warmer epilimnetic water from Lake Norman while retaining cooler hypolimnetic water below elevation 725 ft (204 m) msl. Lake Norman is the source of recirculated condenser cooling water for both McGuire Station and the 2025 MW electrical coal-fired, Marshall Steam Station, located on the west shore of the lake, approximately 18 km (11 miles) north of the dam (Fig. 1-2).
Lake Norman, the largest impoundment in North Carolina, has a surface area of 13,166 ha (32,510 acres) at full pond elevation 231.6 m (760 f t) ms t , a shore-line of approximately 840 km (520 miles), a mean depth of 10 3 m (33.7 ft) and a volume of 1.350 x 10' m (1.094 x 108 ac ft). A drainage area of roughly 2
4662 km (1800 sq. miles) yields a mean annual flow of 75.6 m /s (2670 cfs) 8 at the dam, resulting in an average theroretical retention time of 207 days.

The present eaximum allowable drawdown is 7.6 m (25 f t), or 224 m (735 f t) i est (Ref. 1). When McGuire becomes operational, maximum allcwable drawdown will be reduced to 4.6 m (15 ft), or 227 m (745 ft) msl. Since the comple- ,
tion of the hydroelectric station in 1964, the actual recorded' maximum draw-down has been 3.7 m (12 ft). An area-volurre curve for Lake Norman is present-ed in Figure 1-3 P

CHAPTER 11 PLANT OPERATING DATA UNIT INFORMATION McGuire Nuclear Station has two independent generating units, each rated at 1180 MW electrical and powered by a pressurized water reactor for a total net electrical capacity of 2360 MW electrical. Units I and 2 are presently sched-uled for commercial operation in 1980 and 1982, respectively.
INTAKE CONFIGURATION The condenser cooling water (CCW) system for McGuire Nuclear Station includes two intake structures (Fig. 2-1). The upper intake, which contains four CCW pumps per unit, is located in a man-made embayment approximately 732 m (800 yd) east of Cowans Ford Dam and withdraws water between 219 m (715 ft) and 227.1 m (7h5 ft) msl. The low level intake is located near the base of the dam and draws water between elevations 199.3 m (654 f t) and 204.2 m (670 f t) mst, approximately 27.4 m (90 ft) below the full pond lake surface. This low level structure was built during the construction of Cowans Ford Dam in the early 1960's to serve a future thermal power generating station. Water may be pumped at a maximum rate of 57 m'/s (2000 cfs) from the low level intake through three pumps per unit to the forebay of the upper intake where it mixes with upper intake water. The mixture is then pumped into the CCW system at flow rates up to a maximun of 128 m8 /s (6526 cfs) (Table 2-1).
The quantities and sources of cooling water used are determined by the temper-ature of the surface inlet water and the need to control the discharge temper-ature. From late fall to early spring, surface waters will supply the entire condenser cooling water demand, and only two upper intake CCW pumps will be 8_

operated per unit. As inlet temperatures increase, first three, then all feur pumps will be employed for each unit. During the warmest months, cooler hypolimnetic water will be drawn through the low level intake at a rate nec-essary to maintain the sverage monthly discharge temperature specified in the McGuire NPDES permit.
OlSCHARGE CONFIGURATION Condenser cooling water from McGuire Nuclear Station is discharged to Lake Norman through a 1 km (0.6 mile) long discharge canal (Fig. 2-1). This canal has an average depth of 12.2 m (40 ft) when Lake Norman is at full pool.
Heated effluent from the canal mixes initially with surface waters of the main lake before stabilizing vertically and spreading over the lake surface, ulti-mately dissipating its heat to the atmosphere.
Condenser cooling water temperature increase (AT) is inversely proportional to the CCW flow. During the winter when surface inlet temperatures are the coolest, CCW aT's reach their maximum of 14.2*C (25.5 F). Condenser cooling water AT's decline to 8.9 C (16.0*F) in the summer when the warmest inlet tem-peratures occur (Table 2-1) . Note that these CCW aT's reflect McGuire operat-ing at 100% load.

. CHAPTER lli PREDICTIVE MODELING HYDROTHERMAL PHYSICAL MODEL in 1971 Duke Power Company commissioned the Alden Research Laboratories to build a physical model of Lake Norman at their facilities in Holden, Massa-chusetts. The main purpose of this model was to study the hydrodynamics of Lake Norman and provide insight to the relationships between the hydraulics and heat transfer aspects of the lake.
Physical Model Description .
The Lake Norman physical model was constructed Indoors and covered an area 85 feet wide by 160 feet long. The lake area modeled extended from just below Lookout Shoals Dam to Cowans Ford Dem. Significant features of the Lake Nor-man generating complex included in the physical model were: 1) the Cowans Ford Hydroelectric Station submerged weir; 2) the low level and upper level intakes for McGuire Nuclear Station; and 3) the intake cove skimmer wall and discharge canal for Marshall Steam Station. Condenser cooling water flow rates and corresponding CCW LT's were modeled for each plant as were the Look-out Shoals and Cowans Ford Hydro flow rates. A layout of the model is shown in Figure 3-1.
Scaling ratios for the model were based on Froude number scaling, which stip-ulate that the ratio of inertia to gravity forces be identical in both the model and prototype. Effects of neglecting viscous forces were minimized by choosing a scaling factor which assured fully turbulent model flow regimes as determined by Reynolds number. These basic scaling criteria, in conjunction with model size and testing considerations, resulted in a distorted model with scaling ratios as presented in Table 3-1.

A total of 600 thermistors were used to gather water surface and profile tem-perature data throughout the model. Data were collected every 30 seconds model time, which corresponded to 38 minutes prototype time. Intake and dis-charge temperatures at Marshall and McGuire were among the points monitored.
Figure 3-2 shows the thermistor locations in the vicinity of McGuire.
A validation program was conducted with the model to assure that it accurate-ly simulated observed prototype behavior. This was accomplished by using sur-face temperature data from 20 locations throughout Lake Norman with an Inten-sive study in the vicinity of the Marshall Steam Station discharge canal.
Analysis of the model validation results indicated to Alden and Duke Power Company that the rodel was performing satisfactorily as designed, and could be used to model lake temperatures and flow patterns resulting from the opera-tion of McGuire Nuclear Station. A similar viewpoint was expressed by the U.S.
Atomic Energy Commission (now Nuclear Regulatory Commission) (Ref. 2). Details of the model and its validation program were presented by Alden Research Labo-ratories (Ref. 3).
Physical Model Results One of the main objectives of the model testing program was to determine the effectiveness of Ramsey Creek Cove (Fig. 3-1) as a heat dissipation region for the McGuire effluent. Results indicated that Ramsey Creek Cove would be effective. Modeled surface temperatures in the cove exceeded modeled back-ground temperatures in the lake indicating that McGuire's heated effluent was being transported by thermal density currents throughout Ramsey Creek Cove.
Cye tracer injected into the modeled heated discharge confirmed these findings.
The physical model was also used to evaluate the potential for recirculation between the McGuire intake and discharge locations. Based on model simula-tions of various plant operating modes and seasonal conditions, the conclu-sion was that direct recirculation would be negligible. These tests also pro-vided information concerning isotherm shape and distribution for both Marshall and McGuire. Isotherm patterns predicted by the physical model were used in i
conjunction with mathematical model predictions to obtain affected shoreline information and determine isotherm placement.

MATHEMATICAL MODEL in addition to the Alden hydrothermal physical model, Lake Norman water tem-peratures were simulated using the cooling pond mathematical model developed in 1973 at Massachusetts institute of Technology by Patrick J. Ryan and Donald R. F. Harleman (Ref. 4) . Development of this model was partially funded by Duke Power Company, and was specifically adapted to Lake Norman by Ryan and Harleman.
Mathemetical Model Descriotion The two-dimensional Ryan and Harleman cooling model is an extension of the Huber and Harleman one-dimensional, " deep reservoir" model (Ref. 5). The model allows the lake surface temperature to vary horizontally while simulat-ing stratification of a deep reservoir. Factors such as discharge canals, discharge entrance mixing, density currents, internal diking, and locations of Intake and discharge structures are incorporated in the model. In the adaptation of the model to Lake Norman, the effects of McGuire Nuclear Sta-tion, Marshall Steam Station, Cowans Ford Hydroelectric Station and inficws from Lookout Shoals were incorporated.
Duke used the model to simulate water temperatures which would have occurred in Lake Norman if Marshall and McGuire had operated during the 20 year period, 1951-1970. The major inputs for the 20 year simulation were as follows:
- 1. Daily average dry bulb and dew point temperatures, wind speed (Charlotte Airport) and solar . radiation (Greensboro-High Point Air-port).
the condenser cooling water) were varied daily based on intake tem-perature as will be done in actual operation.
3 Lake Norman surface elevations were varied monthly using a simulated worst year developed by taking the lowest monthly averaged lake level l which actually occurred, for each month, from the period 1963-1974 (the lake completed filling in April, 196h) (see Table 3-2).

Marshall and McGuire capacity factors varied monthly using a simu-lated worst case year for each plant developed by taking the high-est monthly averaged capacity factor which is predicted to occur, for each month, from the period 1980-1992 (period when both plants were to be in full operation; see Table 3-2). capacity factors are defined as energy produced relative to energy production capability at 100% load. It should be noted that capacity factors used in this computer simulation reflected the best estimate for meeting capacity requirements in the 1980's and early 1990's. These estimates were based on the optimized economical dispatch of generation capability to meet projected loads and included scheduled and unscheduled unit outaqes. By using the composite worst operating year, scheduled unit outages for McGuire are not included, which has added to the con- '
servativeness of this worst case composite capacity favor year.

Mathematical Model Results The Ryan and Harleman mathematical model 20 year simulation predicted dis-charge temperatures for both McGuire Nuclear Station and Marshall Steam Sta-tion. These monthly average discharge temperatures are presented in Tables 3-3 and 3-4. t McGuire is predicted to have a monthly average discharge temperature of 35 C (95*F) for the summer months of July and August. On three occasions during the 20 years simulated (August of 1952, 1953 and 1954) the model results in-l L - dicated that the McGuire monthly average discharge temperature would reach 35.5*c (96*F) (Table 3-3) . These model simulations assumed that McGuire judiciously utilized the cooler hypolimnetic lake water to maintain a 35*C j
(95*F) discharge temperature. During the remaining 17 years, McGuire's dis-charge temperature, as predicted by the model, could have been maintained be-low 35'C (95*F). However, during extremely warm summers, utilization of the low level intake earlier in the summer to achieve discharge- temperatures less than 35*C (95*F) would result in the late summer peak temperatures exceeding 35*C (95'F) .

"f the 20 years simulated, the period 1952-1954 resulted in the highest pre-dicted discharge temperatures for both McGuire and Marshall. From these years, an extreme winter, spring, and summer month were chosen based on predicted plume size and discharge temperatures. The operating conditions for these extreme cases with predicted monthly average intake, discharge and background temperatures for McGuire and Marshall are presented in Table 3-5 Resulting monthly average thermal plume acreages, affected shorelines and respective per-centages of the total Lake Norman surface area and shoreline for both McGuire and Marshall are also given in Table 3-5 Illustrations of the extreme winter, spring, and summer 32.2*C (90*F) and 2.8"c (5*F) above background temperature isotherms for both McGuire and Marshall are presented in Figures 3-3, 3-4, and 3-5, respectively. The largest 2.8*c (5 F) excess isotherm area for McGuire was prsuicted for the extreme winter month of December 1952, to encompass 1140 ha (2800 ac), or 11% of the Lake Norman surface area. For the extreme spring and summer months (April and August 1953), 810 ha (2000 ac) and 690 ha (1700 ac),
respectively, were predicted to exceed the 2.8"C (5 F) isotherm. This repre-sents 7% and 6%, respectively, of lake surface area. The 32.2 c (90 F) isotherm for McGuire predicted for the extreme summer month of August 1953 encompassed 530 ha (1300 ac), or L% of the lake surface area.
The percentage of shallow areas in Lake Norman affected by elevated tempera-tures resulting from McGuire and Marshall operation can be estimated by assum-ing an equivalence to the percentage of shoreline affected. Approximately 37 km (23 miles), or 4%, of the Lake Norman shoreline was predicted to be affect ed by the McGuire 2.8*C (5*F) excess isotherm for the extreme winter condition.
Extreme spring and summer 2.8*C (5*F) excess isotherms resulting from McGuire';
operation were predicted to af fect 26 km (16 miles) and 22 km (14 miles), i respectively, or approximately 3% of the shoreline. The extreme summer 32.2*C !
(90 F) isotherm is projected to encompass 18 km (11 miles), or 2% of the shore-line, t
Since Lake Norman will receive the cooling water discharge from both McGuire Nuclear Station and Marshall Steam Station, the effect of McGuire must be eval-uated in the context of Marshall's. operation. For the extreme winter, l

1500 ha (3700 ac), representing 14% of the lake surface area is predicted to exceed background by 2.8'C (5'F) as a result of the operation of both McGuire and Marshall. Approximately 53 km (33 miles), or 6%, of the lake shoreline will be affected. Pr .ted extreme summer conditions will result in 730 ha (1800 ac), or 6%, of the '-ke area being affected by surface temperatures in excess of 32.2*C (90*F),with 26 km (16 miles), or 3%, of the lake shoreline affected (See ~ 3-5 footnotes for basis of percentages).

CHAPTER IV TEMPERATURE AND WATER QUALITY TEMPERATURE DATA Temperature and water quality were monitored on Lake Normr.n at monthly inter-vals from June 1978 through May 1979 (Table 4-1 anc Figure 4-1). Sampling was conducted,in accordance with procedures indicated in Reference 6.
Warmest surface temperatures in the main channel were measuied during July (29.l*C at Location 1.0), in the Ramsey Creek arm during Augest (29.2*C at Location 6.0), and in the Davidson Creek arm during August (23.9 C at Loca-tion 9.5) (Figs. 4-2 through 7 and Appendix Table 1). Coolest surface temp-l eratures were measured during February and ranged between 4.0 and 5.0*C.
Thermal stratification began in Lake Norman in April with a thermocline form-ing at about 15 m (Fig. 4-8). The thermocline was located at a more shallow depth in May. From June through November, it was located progressively deep-er (Figs. 4-9 and 10). The largest observed vertical thermal gradient occur-red in August. Fall overturn occurred during November and Lake Norman was isothermal from December through March (Figs. 4-8 and 11).
Surface temperatures in the Marshall discharge cove between June and Septem-ber were similar to surface temperatures during the same period at other lake locations (Figs. 4-2, 5, and 7). This was probably due to the utilization of hypolimnetic condenser cooling water (CCW) at Marshall. From October through May, the CCW discharge from Marshall was warmer than surface tempera-tures recorded at other locations on the lake (Figs. 4-3 through 7). The Marshall thermal plume extended over the largest surface area of Lake Norman between November and March. Most of the surface temperature decay during this period occurred between Locations 34.0 and 15.0.

VATER QUALITY DATA Changes in dissolved oxygen (00) concentrations were generally related to changes in thermal stratification in '.ake Norman. Surface 00 was generally above 7 mg.1-1 year-round. At Locations 11.0, 34.0, 13.0, 14.0, 50.0, and 15.0, surface DO concentrations were lower than 7.0 mg.1-1 during October due to the low 00, hypolimnetic water discharged from Marshall. Anoxic to near anoxic conditions were present below the thermocline at most locations. From fall overturn to the beginning of thermal stratification, concentrations of 7 mg.1 1 or greater were recorded throughout the water column.
' Changes in concentration of some parameters were usually associated with ther-mal stratification (see Appendix Table 2). During summer stratification, sur-face nitrate + nitrite nitrogen concentrations were usually below 0.30 mg.1-2, whereas bottom waters generally were between 0.30 and 0.45 mg.1-1 Nitrate values decreased to less than 0.20 mg.1-1 during fall overturn, but were greater than 0.20 mg.1 2 throughout the water column from January through May.
Surface nitrate concentrations began decreasing noticeably in June. Concentra-tions of ammonia nitrogen were highest in the bottom waters during stratifica-tion (0.2 to 1.4 mg.1-1) and low during the remainder of the year (< 0.10 mg.
1 2). Total phosphorus and iron were also highest in the bottom water during stratification (0.015 to 0.030 mg.1-2, and 1.0 to 4.0 mg.1-2, respectively).
Surface total phosphorus concentrations were generally less than 0.015 mg.1-1-P.
Total fron concentrations in the surface waters were generally less than 1.0 mg.1-3 Turbidity was also generally higher in the bottom waters during stratification, ranging from 30 to 50 NTU. Downlake surface turbidity was usually below 20 NTU whereas uplake values were often higher, up to 80 NTU. Alkalinity usual-ly ranged from 9 to 15 mg.1-1 as CACO 3 except during the height of stratifica-tion when bottom values approached 25 mg.1-1 as CACO . The pH of the lake 3
usually ranged from 6.0 to 7.5 standard units with occasional values up to 8.3 in the surface waters during the summer.
Other variables were not as directly associated with thermal stratification.
l Specific conductance varied little throughout the year with a typical range of 38 to 40 1;mho.cm-I. Filterable silica varied from 3 0 to 4.5 mg.1 .
l
. i i
Magnesium concentrations ranged from 1.0 to 1.5 mg.1-2, and calcium from 2.0 i to 3 5 mg.1-2 Filterable orthophosphate concentrations were usually less l' than 0.005 mg.1-2 with occasional values up to 0.008 mg.1-1 i

CHAPTER V BIOLOGICAL DATA PHYTOPLANKTON-PERIPHYTON COMMUNITY The phytoplankton and periphyton community was sampled monthly from June 1978 through May 1979 (Table 4-1 and Fig. 4-1). Samples were collected in accord-ance with procedures indicated in Reference 6.
Densities of phytoplankton (Figs. 5-1 through 5 and Appendix Table 3) ranged from 139 to 4456 units.ml-1 on Lake Norman. The lowest densities were observ-ed at Locations 60.0 and 14.0 prior to fall overturn. These low densities were probably directly related to the Marshall skimmer wall. Lowest lake-wide densities occurred during December. Highest lake-wide densities were ob-served during February and March in the main channel and during May in the Ramsey Creek arm. Densities in the main channel and the Ramsey Creek arm were generally similar except during February and March, when main channel densi-ties were approximately two to three times higher. Downlake densities in the main channel tended to be higher than those uplake during September, October, and March. The reverse was true in January and February with no clear trends in the Ramsey Creek arm except for the tendency of densities at Location 3 9 and 4.0 track those at Location 1.2 during February and March. This was prob-ably due to use of the upper level intake pumps at McGuire to provide service water and for testing purposes.
Phytoplankton community composition was more associated with the seasons than with locations on Lake Norman. From July through September green algae was the dominant algal class. Anabaena, a blue green alga, was co-dominant at some uplake locations in August. Dinoflagellates were important in terms of biovolume in September and October. Diatoms were the co-dominant taxa with cryptomonads at uplake locations during October and November. Diatoms did not become co-dominant with green algae at downlak'e locations uniti November.' From December through April diatoms were the dominant class throughout the lake, l except during February and March in Ramsey Craek. Melosira italica was most often the dominant diatom taxon throughout the lake the crypotomonads gained-
[
. i
co-dominace with diatoms in Ramsey Creek in February and the crypotomonad Rhodomonas dominated in March. The lake was dominated by Rhodomonas or other flagellates in May and June.
Total densities of periphyton ranged from 2.77 X 107 to 3.85 x 1018 units.m -2 (Figs. 5-6 through 8 and Appendix Table 4). Organic accumulation rates ranged from 2.60 to 266 mg.m 2.d 1 (Figs. 5-9 through 11 and Appendix Table 4). The lowest lakewide densities and organic accumulation rates occurred during the winter months of January and February. Highest densities and accumulation rates were during the months of May and June, with a secondary peak during the fall at downlake locations. Periphyton densities were slightly lower in Ram-sey Creek than in the main channel from July through February, and slightly higher the remainder of the year. Periphyton densities were generally greater at uplake locations during the warmer months, whereas no clear trends were evi-dent during the remainder of the year. Organic accumulation rates were more variable than were densities. No definitive trends in accumulation rates were evident between locations in the Ramsey Creek arm and those of the main chan-nel. Similarly there were no clear trends between uplake and downlake loca-tions. Diatoms dominated the periphyton community composition year-round.
Green and blue green algae were second and third in abundance, respectively.
No rare or endangered species of phytoplankton were Identified from Lake Nor-man collections. The same is true of aquatic macrophytes, which constitute a very minor component of the primary producers in Lake Norman.
ZOOPLANKTON COMMUNITY The zooplankton community of Lake Norman was sampled monthly from June 1978 through May 1979 (Table 4-1 and Fig. h-1). Samples were collected in accord-ance with procedures indicated in Reference 6.
Total densities of zooplankton ranged from 2450 to 498,000 organisms.m-3 (Figs. 5-12 through 16 and Appendix Table 5). The lowest density was in the Marshall CCW intake sample in September prior to fall overturn. Lowest lake-wide densities occurred during July and December. Highest lakewide densities
occurred during March and April. Densities in the main channel and Ramsey Creek arm were generally similar. Exceptions were during March when main i channel densities were slightly higher, and during September, October, and January, when Ramsey Creek arm densities were higher. Uplake densities in the main channel were generally higher than those downlake except during Sep-tember and March, when densities downlake were two to three times higher than those uplake. Zooplankton densities tended to be higher in the upstream end of the Ramsey Creek arm than near its confluence with the main channel. Ex-ceptions to this trend were noted in June and from March through Hay.
Zooplankton community composition was more associated with seasons than with locations on Lake Norman. Rotifers numerically dominated the community, usu-ally comprising over 50% of the zooplankton. The percentage of rotifers was highest in the winter and spring months, commonly being 70% and occasionally 90% of the community. Keratella spp. and Conochilus unicornis were abundant year-round. During the warmer months Conochiloides spp. and Ploesoma truncatum were also abundant, as were Synchaeta spp, and Polyarthra vulgaris during the cooler months. Cladocera comprised a minor component of the zoo-plankton community, rarely exceeding 10% of the total density. Bosmina longirostris was present year-round and Diaohanosoma leuchtenbergianum and Daphnia spp. were present during the fall and winter months. Copepods com-prised the remainder of the zooplankton community. Immature copepods, parti-cularly nauptli and cyclopold copepodids were most abundant. Adult copedods present most often were Tropocycloos prasinus and Diaotomus mississippiensis.
No rare of endangered species of zooplankton were Identified from Lake Norman collections. ,
BENTHIC MACROINVERTEBRATE COMMUNITY The bentic macroinvertebrate community was sampled quarterly from June 1978 through May 1979 (Table 4-1 and Fig. 4-1). Samples were collected in accord-ance with procedures indicated in Reference 6.
Benthic macroinvertebrate densities in Lake Norman ranged from 195 to 16,500 organisms.m.2 and biomass ranged from 135 to 85,00 mg.m-2 (Figs. 5 17 through
20 and Appendix Table 6). The lowest lakewide density occurred during July and the highest during April. Sicmass paralleled this trend, except that slightly higher values were observed in January than in April. These lake-wide trends reflected changes at the sublittoral depths (7 to 15 m), since little change was observed in total density and biomass at the profundal depths (26 to 34 m). Little difference was evident between the Ramsey Creek arm sub-littoral-locations and those of the main channel. Uplake densities in the main channel were generally greater than those of downlake locations in July and October; however, this pattern was usually reversed in January and April. No clear trends were observed for biomass data. There was also no definitive trend among biomass and density data for locations in the Ramsey Creek arm.
Benthic macroinvertebrate community composition was more associated with sea-son and sample depth than with location on Lake Norman. Oligochaetes, chiro-nomids, and Chaoborus puncticennis larvae dominated the benthic communities numerically and together with Hexagenia nymphs and Corbicula dominated the biomass. At profundal depths, oligochaetes dominated density and biomass year-round. Only during January and April did C. puncticennis become abun-dant, achieving up to 38% of the total density and 25% of the biomass. No other taxa comprised more than 5% of density or biomass at profundal depths.
At sublittoral depths chironomids and Chaoborus comprised most of the total density year-round. Chaoborus generally canprised a greater percentage of the total density than chironomids during October and declined through April.
Corbicula and Hexagenia dominated the sublittoral biomass at many locations in July and April. Chaoborus and chironomids were usually dominant components of the biomass in October and January. No rare or endangered species were Identified f rom Lake Norman collections.
I FISH COMMUNITY The adult fish community of Lake Norman was sampled from June 1978 through May 1979 (Table 4 -1 and Fig. 4 -1) . Samples were collected in accordance with procedures indicated in Reference 6, except that a rotenone collection was made at the more suitable Location 19.0 instead of 13.0.
l l
~46- s
Gillnet catch ranged from 0 to 78 fish - (17 to 18 hr gillnet set) (Figs.
5-21 through 24 and Appendix Table 7), electrofishing catches from I to 688 fish 600 m shoreline (Figs. 5-25 through 27 and Appendix Table 8), adult fish trawling catches from 0 to 304 fish - 1000 m weighing frem 0 to 66.6 g 1000 m (Figs. 5-28 and 29 and Appendix Table 9), and rotenone catches from 4398 to 10 298 fish ha weighing from 43.7 to 196.3 kg ha (Table 5-1 and 2 and Appendix Table 10). Lowest lakewide values for gillnetting and electrofishing occurred during January, February, and March. Exceptions to this occurred at Locations 14.5 and 14.7 in the Marshall discharge cove, where catches were usually the highest recorded over the one year monitoring period.
Highest lakewide values for gillnetting and electrofishing occurred during April and May.
More fish were caught in gillnets sets at uptake locations than at downlake locations during every sample period. Location 14.7 in the Marshall discharge cove had the highest number of gillnetted fish throughout the year. Gillnet catches declined from July through January and peaked in April. Electrofish-ing catches were generally higher uplake also. Locations 14.5 and 14.7 in the Marshall discharge cove had the highest number of fish during most months of the year. Rotenone data generally indicated higher estimates of abundance and standing crop at downlake locations compared to those uplake.
The relative abundance of fish was similar at ths Ramsey Creek arm and down-lake main channel locations, as determined by gillnetting and trawling. No consistent pattern was observed in electrofishing catches at these two areas.
Within Ramsey Creek arm, Locations 5.0 and 6.0 had higher catches by gillnet-ting than Locations 3.0 and 4.0. The gillnet catches in the Ramsey Creek arm remained consistently high from June through November, dropped off to zero in February and the increased steadily to the highest observed value in May.
Electrofishing catches in this arm rose steadily from June through October, ,
declined steadily through February, then increased in May. The electroffsh-ing data exhibited a bimodal peak in relative abundances in October and May.
Trawling in Ramsey Creek arm resulted in both higher abundance and standing crop estimates at Location 4.5 than 5.0.
I
! Centrarchids dominated the electrofishing samples throughout the year. The {
most abundant species were redbreast sunfish (Leecmis gjritus), bluegill 4
l I 5t
(l.. macrochirus), largemouth bass (Microoterus salmoides), and whitefin shiner (Notropis niveus). Yellow perch (Perca flavescens) was abundant in electrofishing samples during the winter. Gillnet catches were generally dom-Inated by gizzard shad (Dorosoma ceoedianum) and quillback carpsucker 1 (Carolodes cyorinus) throughout the year. Snail bullhead (lctalurus brunneus),
flat bullhead (1. platyceohalus), and white bass (Morone chrysoas) were also abundant during the summer and fall. Trawl catches were comprised almost ex-clusively of threadfin shad (0,. petenense) and gizzard shad. The rotenone samples were dominated by bluegill and yellow perch at all locations. Thread-fin shad, however, made up 20 to 25% of the fish collected at Locations 8.5, 14.7, and 68.0; redbreast sunfish were abundant at other rotenone locations.
Gizzard shad comprised the largest portion of standing crop in rotenone col-lections at most locations; at Location 4.0, over 80% of standing crop (blo-mass) was accounted for by this species. Carp (Cyorinus carolo) were also a large part (12 to 28%) of the standing crop in rotenone collections at all locations except 4.0. No rare or endangered species of fish were identified from Lake Norman collections.
