Effects of flow fluctuation and redd dewatering on salmonid embryo development and fry quality. Research technical completion report. Contract No. DE-AC79-79BP10848 Item Info
![During the fall and winter 1979-1980 tests were conducted in a section of the Middle Snake River within Hells Canyon to determine the effects of hydroelectric power peaking on fall chinook salmon (Onchorhycus tshawytscha) embryo incubation and fry quality. Additional simulated peaking tests were conducted at Hayden Creek research station using artificial stream channels. Steelhead trout (Salmo gairdneri) and chinook salmon egg dewatering tolerance tests were conducted at the Hayden Creek Station using 16 independent flow controllable chambers. In Hells Canyon, no definitive relationship was found between embryo survival and the incidence of flow fluctuations and periodic redd exposure. However, the highest embryo survivals occurred in areas dewatered the least.
