Mobile hydroacoustic surveys of 11 stations in J. Strom Thurmond (JST) Lake from February 1986 to October 1988 provided data to aid in identifying critical areas, times, and water release regimes for fish relative to proposed pumpback of water from JST Lake to Richard B. Russell (RIiIR) Lake. Mean relative biomass (volts2/m2 ) usually was significantly higher in the tailrace (0-450 m below RBR Dam) than in the tailwater (1-7 kmbelow RBR Dam), tributary, or lake areas in spring and summer; whereas in fall and winter, biomass was often lower than or did not differ from that in other areas....

Data from August samples of fish in quarter (900 arc) hauls of a 15.2- X 1.8m bag seine were analyzed to determine effectiveness of seining for detecting species presence, forecasting future relative abundance of larger length classes of the same species, and assessing the value of seining as an indicator of prey availability for piscivores in Kansas reservoirs. The data set contained 98 reservoir-years of samples from 24 impoundments with 2-7 years of data per reservoir. The median number of hauls per reservoir and year was 19; the range was 10-30. Bag seines effectively sampled only...
