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.
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.
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.
This project entails placing large woody material (LWM) along the mainstem Upper Wenatchee River in crib-like structures. The length of the treatment will be for approximately 100 yds.
Satus Dam—also known as the Shadduck Dam—was installed in Satus Creek over a half-century ago by Wapato Irrigation Project (WIP). The dam was used to divert water to supplement the irrigation water in the Satus District of WIP.
The Chewuch River Mile 10 Fish Habitat Enhancement Project (RM10), improves stream complexity by improving available instream habitat, increasing side channel and off channel habitat, and stabalizing eroding banks.
Enhance instream habitat and water quality to benefit Middle Columbia steelhead and spring Chinook at three priority sites totaling 0.29 cumulative river miles.
Yakama Reservation Watershed Project (YRWP) proposed to remove a culvert on North Fork Simcoe Creek just above its confluence with Diamond Dick Creek within the closed area of the Yakama Nation Reservation.
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.
Branch Creek enters North Fork Toppenish Creek at river mile 3.2, and drains a 23-square-mile watershed. Mid-Columbia River steelhead use the stream for spawning and rearing.
Yakama Reservation Watersheds Project staff completed a bank stabilization and floodplain restoration project in and adjacent to Ahtanum Creek.
