Distribution and Flux of Fish in the Forebay of the Dalles Dam in 2003. Final Report
This study was conducted by the Pacific Northwest National Laboratory for the U.S. Army Corps of Engineers, Portland District and its Anadromous Fish Evaluation Program. The study was part of the Corps' efforts to improve conditions for juvenile salmonids at The Dalles Dam. The Dalles Dam does not have a juvenile bypass or collection facility to aid downstream migrants. Presently, spillway improvements are being pursued, and a proposal for a guidance structure in the forebay at The Dalles Dam has recently been suggested by the U.S. Army Corps of Engineers and regional resource managers as a potential approach to improve the passage survival of juvenile salmon at the dam. The guidance structure would be designed to alter the horizontal distribution of fish in the forebay and thereby to divert fish from the powerhouse to the spillway. This study was initiated to gather baseline data on the distribution of juvenile salmon in the forebay at The Dalles Dam, and to relate that distribution to ambient factors (flow, bathymetry, etc.) and the present structures at The Dalles Dam. This information will provide baseline data for the development of a behavioral guidance structure and surface bypass alternatives for juvenile salmon at The Dalles Dam.
