Distribution and relative abundance of fishes in littoral areas of Chief Joseph Reservoir, Columbia River Distribution and relative abundance of fishes in littoral areas of Chief Joseph Reservoir, Columbia River
We surveyed fish assemblages in littoral areas of Chief Joseph Reservoir of the upper Columbia River to aid in understanding this ecosystem. Fish distributions and abundances were examined during April-July 1999 in relation to environmental conditions in the reservoir. We also compared the fish assemblages in Chief Joseph reservoir in 1999 to a past study conducted during 1974-1975, and...

Acute exposure to gas-supersaturated water does not affect reproductive success of female adult chinook salmon late in maturation Acute exposure to gas-supersaturated water does not affect reproductive success of female adult chinook salmon late in maturation
At times, total dissolved gas concentrations in the Columbia and Snake rivers have been elevated due to involuntary spill from high spring runoff and voluntary spill used as a method to pass juvenile salmonids over dams. The goal of this project was to determine if acute exposure to total dissolved gas supersaturation (TDGS) affects the reproductive performance of female chinook salmon...

Gas bubble disease in resident fish below Grand Coulee Dam: final report of research Gas bubble disease in resident fish below Grand Coulee Dam: final report of research
Fish kills have occurred in the reservoir below Grand Coulee Dam possibly due to total dissolved gas supersaturation (TDGS), which occurs when water cascades over a dam or waterfall. The highest TDGS below Grand Coulee Dam has occurred after spilling water via the outlet tubes, though TDGS from upstream sources has also been recorded. Exposure to TDGS can cause gas bubble disease in...
