【 摘 要 】
This report documents the results of a steelhead kelt passage study conducted by the PNNL for the U.S. Army Corps of Engineers at Bonneville Dam in early spring 2007 and 2008. At the Second Powerhouse, a surface flow outlet called the corner collector (B2CC) may be an effective non-turbine passage route for steelhead kelt moving downstream in early spring before the main juvenile emigration season. The goal of this project was to inform management decisions regarding B2CC operations by estimating the number of kelt using the B2CC for downstream passage at Bonneville Dam prior to the juvenile spring migration season. We performed a hydroacoustic study from March 2 to April 10, 2007 and from March 13 to April 15, 2008.【 预 览 】
