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.
A major limiting factor affecting the healthy function of the watershed/habitat is the presence of an unscreened surface water diversion located on South Fork Simcoe Creek.
On August 6, 2011, Yakama Nation Fisheries, Yakama Reservation Watersheds Project (YRWP) completed the implementation of a restoration action at two road/stream interfaces on Panther Creek to improve stream function and facilitate fish movement.
The factors limiting fish passage and habitat degradation at the Durham Irrigation Dam restoration site were the result of an obsolete irrigation diversion dam.
Yakama Reservation Watersheds Project staff completed a bank stabilization and floodplain restoration project in and adjacent to Ahtanum Creek.
Enhance instream habitat and water quality to benefit Middle Columbia steelhead and spring Chinook at three priority sites totaling 0.29 cumulative river miles.
The Sunnyslope Side Channel Project is located on the Wenatchee River at RM (river mile) 1.4. This excavated side channel is approximately 1,350 feet in length.
Agency Creek enters Simcoe Creek at river mile 9.5, and drains a 23-square-mile watershed. Middle Columbia River steelhead use the creek for spawning and rearing.
The Yakama Nation is a federally recognized Tribe, pursuant to the Treaty of 1855 (12 Stat. 951), with authority to manage, protect and restore treaty resources throughout the Pacific Northwest.
The Twisp River Cattle Management Project provides riparian protection for Upper Columbia Steelhead in the Twisp River Watershed. The project was done on federal lands in partnership with the United States Forest Service (USFS).
Yakama Nation Fisheries (YNF) has been exploring sturgeon culture requirements by rearing small numbers of white sturgeon in tribal hatchery facilities since the 1990s. Fish were obtained from various sources, including the private Pelfrey sturge
