Food of Larval Yellow Perch in a South Carolina Reservoir Receiving Heated Effluent

Food of larval yellow perch (Perea flaveseens) from Keowee Reservoir, South Carolina was determined before (1973) and after (1976) power production began a 2,580-MW nuclear power plant Mean water temperatures at 1 m increased 2-3 C throughout the reservoir by 1976. The diet of larvae examined consisted exclusively of zooplankton. Cyclopoid copepods, Diapromus mississippiensis and Diaphanosoma braehyurum were the principal organisms eaten in all areas even though other organism were sometimes more abundant. The operation of the plant reduced zooplankton abundance in the discharge cove while...

Effects Of A Pumped Storage Hydroelectric Plant On Reservoir Trout Habitat

Jocassee Reservoir (3,063 ha) is the upper pool for a 61O·MW pumped storage hydroelectric plant in northwestern South Carolina. Trout (200-225 mm long) have been stocked annually since 1972. The volume of trout habitat during summer has decreased annually from 1973 to 1976, and is associated with increases in the temperature and volume of water pumped from the lower reservoir. The top of the thermocline during September was lowered from about 9 m in 1973 to nearly 19 m in 1976, and trout habitat was reduced by about 65%. On the basis of a regression presented, we predict that trout habitat...
