- Rainbow trout populations in the upper Yakima River Basin have increased due to reduced competition from declining populations of steelhead, chinook salmon, and coho salmon. Changing population abundances have increased the potential for interactions between rainbow trout and steelhead. In 1993, NMFS, in cooperation with WDW, proposed a 1-year radio-telemetry study to determine the spawning distribution, timing, and behavior of rainbow trout in the upper Yakima River Basin. Specific objectives were to: (1) Determine the spatial and temporal spawning distributions of rainbow trout in the upper Yakima River Basin. (2) Describe post-spawning behavior of rainbow trout in the upper Yakima River Basin. (3) Determine the magnitude and causes of mortalities to rainbow trout that were radio- tagged.
