Industrial and agricultural pollution and toxic contamination, dams that block fish migration and access to spawning habitat—the decline of salmon, steelhead, sturgeon, and lamprey in the Columbia River is has many causes. To restore the river and the life that depends upon it, the Yakama Nation Fisheries is employing many and varied strategies, simultaneously. In some areas, habitat recovery is the key; in others, supplementation of salmon runs may need to be the driver.
Evaluating rates of nestling provisioning by adult birds provides insight into foraging strategies and reproductive effort. In most biparental avian species, both males and females provision the young, although this task is not always shared equal

This report presents the findings of the Nason Creek Recreation Assessment. The goal of this study is to support the work of the Yakama Nation and partners as they continue to seek ways to balance the ecological benefits of habitat restoration pr
Columbia River steelhead are iteroparous (able to spawn multiple times). However, as post-spawned steelhead (kelts) attempt to migrate downstream to return to the ocean, their survival is adversely affected by major dams.
