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...


Effects of Effluents from Trout Hatcheries on the Benthos and Fish in Receiving Streams

This study evaluated the effects of discharges from three southeastern trout hatcheries on the benthic organisms and fish in the receiving streams. The U. S. Fish and Wildlife Service hatcheries were at Suches, Georgia; Walhalla, South Carolina; and Brevard, North Carolina. Although effects differed somewhat for each hatchery, the numbers and kinds of both benthos and fish generally increased immediately downstream from the hatchery outfalls. Pollution intolerant benthic organisms were not lost from the fauna below the hatchery outfalls. No detrimental changes in the fish communities were...


Florida's State-Wide Tagging Program

The Florida Game and Fresh Water Fish Commission has conducted a state-wide fish tagging program for the years 1961 through 1964. Rewards from $25.00 to $10,000.00, offered by the Joseph Schlitz Brewing Company, insured a high return to the Commission of those fish caught by the anglers. During the four year period, 28,805 fresh-water fish were tagged and released in 120 lakes, rivers, and canals throughout the state. Ten species of fish were tagged with the largemouth bass providing the highest returns. 27.9 per cent of the 9,079 bass tagged were returned. The recaptures for six other...
