Abstract
A 4-year radio-telemetry study was made of steelhead in the Yakima River basin, with the objectives of determining the run timing, passage patterns at irrigation diversion dams, and morphometric characteristics of different Yakima basin steelhead substocks and determining where and when the substocks become separated; evaluating adult steelhead passage at Yakima River basin diversion dams; determining steelhead migration , temporal distribution, and habitat utilization in the Yakima River basin; identifying spawning distribution and timing of steelhead; and determining the amount and cause of pre-spawning mortality of radio-tagged steelhead. Recommendations are given.Keywords
