Survival and migration behavior of juvenile salmonids at Lower Granite Dam, 2006 Survival and migration behavior of juvenile salmonids at Lower Granite Dam, 2006
We described behavior and estimated passage and survival parameters of juvenile salmonids during spring and summer migration periods at Lower Granite Dam in 2006. During the spring, the study was designed to examine the effects of the Behavioral Guidance Structure (BGS) by using a randomized-block BGS Stored / BGS Deployed treatment design. The summer study was designed to compare...

Survival estimates of migrant juvenile Salmonids through Bonneville Dam using radio telemetry, 2004 Survival estimates of migrant juvenile Salmonids through Bonneville Dam using radio telemetry, 2004
During 2004, the USGS evaluated the survival of radio-tagged yearling and subyearling Chinook salmon and steelhead trout through the ice and trash sluiceway and the minimum gap runner (MGR) turbine unit at Bonneville Dam’s powerhouse 1. Survival was estimated using paired release-recapture models with paired releases made directly into these passage routes and in the tailrace of...

Survival estimates of migrant juvenile salmonids through Bonneville Dam using radio telemetry, 2005 Survival estimates of migrant juvenile salmonids through Bonneville Dam using radio telemetry, 2005
During 2005, we evaluated the survival of radio-tagged yearling and subyearling Chinook salmon and steelhead trout through the Bonneville Dam spillway, powerhouses 1 and 2, the corner collector and juvenile bypass system (JBS) at powerhouse 2, and through all routes collectively using the route-specific survival model. Radio-tagged fish were released at The Dalles Dam and in the tailrace...
