Fish Screen Feasibility Study
DEA conducted a feasibility study and alternative analysis to screen approximately 1,000 cfs of combined hydroelectric power plant supply and irrigation system supply from the Santiam River. Two alternatives were ultimately evaluated: screening the entire canal with an upstream screen and downstream adult fish barrier; and limited screening and fish by-pass around the hydroelectric plant. The preferred alternative of screening the entire canal was approved by Oregon Department of Fish & Wildlife in September, 2000, and the screen and adult fish barrier are currently under design.
