Abstract:

A wide range of planning criteria was used to evaluate the hydropower and fish enhancement alternatives, design options for the alternatives, and alternative plans for Wynoochee Dam. The alternatives included hydropower at Wynoochee Dam, various fish enhancement measures in the vicinity of Wynoochee Dam, and no action. The tentatively selected plan is a 10.2-megawatt nameplate hydropower addition to Wynoochee Dam which would produce an average of 37,400 megawatthours energy per year and a 396,000-pound 190 cubic feet per second hatchery for anadromous fish 3,000 feet downstream of Wynoochee Dam which would add 129,000 adult fish annually to the anadromous fish harvest. Total fish enhancement would be 118,450 fish. Two satellite fish stations for enhancement of fish runs on other Washington coastal rivers are included in the plan. The tentatively selected plan meets the two planning objectives of this study. Author
