MONTICELLO AND PARR RESERVOIRS FISHERIES SURVEYS: FINAL REPORT
1.0 INTRODUCTION
Monticello and Parr Reservoirs are located in the Piedmont region of South Carolina. Parr Shoals Dam impounds the Broad River to form Parr Reservoir (4,400 acres) while Monticello Reservoir occupies most of the Frees Creek watershed. The two impoundments are connected via a pump-storage hydroelectric project on what was formerly Frees Creek, but is now an engineered canal between the two reservoirs. Monticello Reservoir serves as a source of cooling water for the Virgil C.
Summer Nuclear Station operated by South Carolina Electric and Gas Company (SCE&G).
Normandeau Associates was retained by Tetra Tech NUS to conduct two surveys of the fisheries in Monticello and Parr Reservoirs, once during the summer (July 2008) and once during winter (February 2009). This report covers winter 2009.
2.0 METHODS Fisheries of Monticello and Parr Reservoirs were surveyed over the February 26 - 27 and the February 27 - 28, 2009 period, respectively. Sampling gear included boat electrofishing equipment and gillnets. Monticello Reservoir gillnets were set on February 26 and retrieved on February 27.
Electrofishing was also performed on February 27. Parr Reservoir gillnets were set on February 27 and retrieved on February 28. Electrofishing was also done on February 28.
Electrofishing transects and gillnet locations were selected by Tetra Tech and SCE&G in 2006 (Normandeau 2007), and based on sampling locations used in the original CWA Section 316(a) study for Summer Station. Five gillnet stations and five electrofishing transects were established in Monticello Reservoir. Three gillnet stations and three electrofishing transects were established in Parr Reservoir. Figure 1 shows sampling locations used in both the initial phase of the study (fall 2006 and spring 2007) and in the current phase of the study (summer 2008 and winter 2009). GPS coordinates for these sampling locations are provided in Table 8.
The monofilament gillnets used in the surveys measured 100 feet long by 8 feet wide, with four 25-foot panels of 1, 2, 3, and 4 inch stretch mesh. Nets were set perpendicular to shore in the afternoon
(- 1300 - 1430h) and retrieved the following morning (- 0700 - 1030). The gillnet set in the Fairfield tailrace canal (Parr station 1) was the exception. Due to strong currents associated with FPSF generation, this net was set at an angle approximately 45 degrees to the shoreline. Fishing time ranged from 16.58 to 19.78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br /> at the Parr Reservoir stations and averaged 18.23 hours2.662037e-4 days <br />0.00639 hours <br />3.80291e-5 weeks <br />8.7515e-6 months <br /> (Table 10). At Monticello Reservoir stations, fishing time ranged from 16.85 to 21.50 hours5.787037e-4 days <br />0.0139 hours <br />8.267196e-5 weeks <br />1.9025e-5 months <br /> and averaged 19.12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> (Table 10).
The electrofishing was conducted from an aluminum boat equipped with a 4500-W, 230V gasoline powered generator. A four-electrode array was mounted on a boom and suspended in the water approximately 2 m in front of the boat; the cathode array was secured to the bow of the boat. Direct current (DC) discharge was controlled by a Smith-Root Model VI electrofisher set to deliver 672V at 5-6 amps at a frequency of 60 pulses/sec. Current to the electrodes was pulsed by a foot switch operated by a netter at the bow. Electrofishing was conducted in the early morning hours along shallow shorelines. Electrofishing times ranged from 902 to 909 seconds at the Parr Reservoir stations and averaged 906 seconds (Table 9). At the Monticello Reservoir stations, electrofishing times ranged from 902 to 923 seconds and averaged 907 seconds (Table 9).

MONTICELLO AND PARR RESERVOIRS FISHERIES SURVEYS: FINAL REPORT All fish were identified to species, measured to the nearest millimeter and weighed to the nearest gram. When a species exceeded 20 individuals at a station, per sampling method, the individuals were counted, recorded and an aggregate weight was recorded. A few specimens were retained to confirm ID and as reference specimens.
3.0 SPECIAL - STATUS SPECIES None of the fish collected was state or federally listed. None has been designated a species of concern. All fish collected were typical of Piedmont lakes, rivers and streams.
4.0 RESULTS A total of 461 fish (both gear types) representing 20 species were captured on Monticello Reservoir during the winter study period (Tables 1 and 2). Bluegill (33.4%), white perch (21.5%), largemouth bass (7.6%), gizzard shad (6.7%) and channel catfish (5.6%) were the five species most commonly collected (Table 3). A total of 355 fish were collected by electrofishing (Table 2). Bluegill, whitefin shiner and white perch dominated Monticello Reservoir electrofishing collections (Table 4). Gillnets captured a total of 106 fish (Table 2). White perch were numerically dominant in Monticello Reservoir gillnet collections (Table 5). Almost 40 percent of fish collected in gill nets were white perch.
A total of 131 fish (both gear types) representing 19 species were captured on Parr Reservoir during the winter study period (Tables 1 and 2). Bluegill (33.6%), largemouth bass (9.2%), spottail shiner (9.2%), channel catfish (9.2%) and blue catfish (8.4%) were the five most common species (Table 3).
A total number of 90 fish were collected by electrofishing (Table 2). Bluegill dominated Parr Reservoir electrofishing samples (Table 4). Eastern silvery minnow and spottail shiner were also frequently collected (Table 4). Gillnets on Parr Reservoir captured a total of 41 fish (Table 2).
Channel catfish and blue catfish were the species most often collected (Table 5).
The two areas most likely to be affected by operation of proposed new units are (1) Monticello Reservoir in the area of the proposed new intake and (2) Parr Reservoir in the area of the proposed new blowdown structure. These areas are in the vicinity of Monticello Reservoir station 3 and Parr Reservoir station 3, respectively. Monticello Reservoir station 3 and Parr Reservoir station 2 showed highest measures of species richness in winter 2009 (Table 6).
Based on winter 2009 sampling results, the fish communities of Monticello Reservoir and Parr Reservoir were similar. Bluegill, largemouth bass, and channel catfish were numerically dominant in both reservoirs (Table 3). White perch were very abundant in Monticello Reservoir and very few were collected in Parr Reservoir (Table 3). In the summer 2008 sample, a few more white perch were collected on Monticello Reservoir than Parr Reservoir (Normandeau 2008, Table 3). However, the relative abundance for white perch was greater on Parr Reservoir (7.6%) than Monticello Reservoir (3.6%) (Normandeau 2008, Table 3). Comparing both seasons (summer 2008 and winter 2009) for Monticello Reservoir, bluegill was among the most abundant species (Table 3 - summer 2008 /
winter 2009). Gizzard shad and white perch were among the five most abundant species in Monticello Reservoir for both seasons (Table 3 - summer 2008 / winter 2009). Both species did a reversal in terms of relative abundance between the seasons. Gizzard shad (42.2%) were very abundant while white perch (3.6%) were not in the summer of 2008 (Normandeau 2008, Table 3). In winter of 2009, 2009 Summer Station Fisheries Report-Winter Final.doc 4/27/09 2 NormandeauAssociates, Inc.
MONTICELLO AND PARR RESERVOIRS FISHERIES SURVEYS: FINAL REPORT gizzard shad (6.7%) were significantly less abundant while white perch (21.5%) were much more abundant (Table 3). Parr Reservoir had similar results to Monticello Reservoir in terms of bluegill relative abundance between both seasons (summer 2008 and winter 2009). Bluegill was among the top two in relative abundance for both seasons (Table 3 - summer 2008 / winter 2009). Largemouth bass and blue catfish were among the top five in terms of relative abundance for both seasons and increased only a few percentage points from summer 2008 to winter 2009 (Table 3 - summer 2008 /
winter 2009).
Water quality data for Monticello Reservoir and Parr Reservoir is presented in Table 7. Monticello Reservoir temperatures ranged from 10.5 to 17.7°C at the surface and 10.5 to 11 .0°C at the bottom.
Parr Reservoir temperatures ranged from 10.6 to 11 .0°C at the surface and 10.2 to 10.90 at the bottom. Dissolved oxygen concentrations in Monticello Reservoir ranged from 11.0 to 12.5 mg/1 at the surface and 10.7 to 11.2 mg/1 at the bottom. Parr Reservoir dissolved oxygen concentrations ranged from 11.2 to 12.5 mg/l at the surface and 11.4 to 11.7 mg/I at the bottom. Both reservoirs exhibited similar water quality chemistries. The largest range in temperature occurred on Monticello Reservoir. The widest range of dissolved oxygen occurred in Monticello Reservoir.
Both reservoirs appear to be well mixed in terms of dissolved oxygen from top to bottom. Super saturation (12.0 mg/I) is approached at all depths in both reservoirs. Station 4 (near warm water discharge) had the highest surface temperature (17.7QC) and did not have a significantly lower amount of dissolved oxygen than the other four stations (Table 7). The expectation is that higher temperature water has less of a carrying capacity for dissolved oxygen that cooler water. The middle and lower depth temperatures for station 4 are very close and in some cases lower compared to the other four stations (Table 7). Dissolved oxygen concentrations at station 4 are very similar to the other stations (Table 7). It appears the warm water plume is staying near the surface at station 4.
5.0 CONCLUSION
S Both reservoirs exhibited good dissolved oxygen concentrations capable of supporting a wide range of fish species as well as numbers of fish. Monticello and Parr Reservoirs also seem to have diverse fish communities that contain predator / prey species in good numbers as well as ancillary species that are important to other activities. Bluegill and largemouth bass were very common in both reservoirs.
Bluegill were the most abundant species in both reservoirs.
