Concurrent Sessions B: Columbia River Passage - Improving Precision of Bonneville Dam Passage Survival Estimates for Juvenile Salmon

Abstract
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
