Abstract:

This study was one of many investigations of the U.S. Army Engineer District, Portland, involving monitoring and assessment of juvenile fish passage at Bonneville Dam. It was a joint study by the ERDC Environmental Laboratory and Pacific Northwest National Laboratory to evaluate the performance of a Prototype Surface Collector and the fish passage efficiency FPE of the extended length bar screen at Unit 8. The goal of this study was to report the first project-wide estimates of FPE, spill efficiency, and spill effectiveness for the Bonneville Project These data provide a valuable baseline for evaluating the performance of future management efforts to improve juvenile fish passage. Detailed statistical methods are presented.
