Abstract

Heated water entering Boomer Lake, Payne County, Oklahoma, resulted in stream conditions being simulated in the power plant discharge riffle. Trichoptera (Cheumatopsyche and Hydropsyche) and Diptera (Simulium vittatum Zetterstedt) were abundant in the riffle and may have supplemented the food supply of fishes in the lake. Populations of Ephemeroptera (Hexagenia), Diptera (Chironomidae), Megaloptera (Sialis), and Oligochaeta (Branchiura sowerbyi Beddard) from two areas on the lake were compared. Both areas were coves, but one had heated water entering it. Since monthly mean numbers of organisms and biomass per individual Hexagenia from the two areas were similar, the heated water apparently had little, if any, effect on the benthos.
