Funders: Salmon Recovery Funding Board (RCO), Department of Ecology, Bonneville Power Administration, Confederated Tribes of the Colville Reservation
Completion Date: September 2025
Location: Lower Peshastin Creek, Chelan County
Cost: $3,510,000
Outcomes: Increase in 3.7 acres of aquatic habitat, over 1,000 pieces of wood added to the creek as engineered log jams and floodplain roughness features, over 2,000 lbs. of lead shot removed and recycled, installation of walking trails and interpretive signage, 2.5 acres of riparian plantings.
The project by Cascade Fisheries involved redirecting a portion of the Lower Peshastin to near its historic channel and placing wood structures strategically along the new stretch of river. In total, 1,100 ft. of new primary channel was created, and 800 ft. of existing channel was restored as a secondary channel. This work has reengaged the floodplain and created vital resting and rearing habitat for ESA-listed salmon species.
Around $300,000 was reinvested in Chelan County through this work, including ~$160,000 to local contractors, ~$60,000 to local businesses, and ~$80,000 generated in local sales tax. Improvements were made to an important public recreation site through the creation of walking trails and installation of interpretive signage.
The restored floodplain was designed to reconnect the river to its natural overflow areas, allowing high water to spread out rather than concentrate in a single channel. During the 2025 flooding, this reduced pressure on banks slowed water velocities and minimized erosion. As a result, the project area remained stable and functioned as intended, absorbing and conveying floodwaters while protecting surrounding habitats and communities.
