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.
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.
This fish habitat enhancement project recreates habitat that is below historical and potential conditions.
Summer- and fall-run chinook were once abundant in the Yakima River Basin, but the runs were decimated as a result of historical land and water development and fisheries management practices.
Dramatic declines in the abundance of anadromous Pacific salmonids have occurred over the last century in the Columbia River basin. Population declines followed harvest, hydrosystem and watershed development, habitat loss and degradation, and red
Four nursery lakes in the Yakima River Basin, which historically produced an estimated annual return of at least 200,000 sockeye, were removed from production in the early 1900s when irrigation storage dams were constructed without passage. The Y
The Yakama Nation is working to restore natural production of Pacific lamprey to a level that will provide robust species abundance, significant ecological contributions and meaningful harvest within the Yakama Nations Ceded Lands and in the Usual

The Western Bluebird (Sialia mexicana) is a secondary-cavity-nesting thrush that breeds in semi-open habitats throughout much of western North America.
In Washington, the White-headed Woodpecker (Picoides albolarvatus) is listed as a species of concern because of its association with old-growth ponderosa pine (Pinus ponderosa) forests. In 2011, we began a color-marking study of
