Public Utility District No. 1 of Chelan County, Washington, (Chelan) owns and operates the Rocky Reach and Rock Island hydroelectric projects located on the Columbia River. Chelan is actively seeking the best measures to protect juvenile salmon and steelhead trout as they pass these projects in their downstream migration to the Pacific Ocean. In 1994 Chelan shifted its efforts at Rocky Reach from a turbine intake diversion screen design to an alternative collection system concept. The alternative concept is expected to attract the migrating fish away from the turbine intakes using a combination of the fish`s natural behavioral tendencies and the unique Rocky Reach forebay approach flow characteristics. This paper describes the attraction system being tested during the spring and summer of 1995 at Rocky Reach Dam, the migrating salmon and steelhead trout behavioral tendencies and unique forebay hydraulic characteristics at Rocky Reach, and the tools used to develop the surface fish attraction prototype.
