Description

In spring 2011, high Columbia River discharge reduced the detection efficiency of the last two fish survival detection arrays downstream of Bonneville Dam by 15-18% at river km (rkm) 113 and 23-32% at rkm 86 relative to 2010 estimates and produced dam-passage-survival standard errors that exceeded a Biological Opinion requirement of SE0.93 and SE

Comments

Gene Ploskey is a senior research scientist with a long career conducting studies to evaluate effects of physicochemical factors and dam operations on reservoir fisheries, fish protection measures at dams, and route-specific dam passage and survival of fish.
