Yakama Reservation Watersheds Project
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 Yakama Nation is working with the U.S.
By the end of the 20th century, indigenous natural coho salmon no longer occupied the mid- and upper-Columbia river basins. Columbia River coho salmon populations were decimated in the early 1900s. For several reasons, including the construction and operation of mainstem Columbia River hydropower projects, habitat degradation, release locations, harvest management, hatchery practices, and genetic guidelines, self-sustaining coho populations were not re-established in mid-Columbia basins.
The Yakama Nation Upper Columbia Habitat Restoration Project (URCHRP) is a project under the Yakama Nation Fisheries Resource Management Program. The project recieves its principal funding through the Columbia Basin Fish Accords.
The intent of the UCHRP is to implement science based habitat restoration benefiting spring Chinook and steelhead on priority streams and river reaches within the Methow, Entiat, and Wenatchee Subbasins, following recommendations contained in the Upper Columbia Spring Chinook and Steelhead Recovery Plan (UCSRB, 2007).
