Nason Creek

Nason Creek was degraded into a straight, disconnected, habitat devoid stream in the 1950s due to levee, railroad, and powerline construction. Chelan county worked to restore habitat, reconnect Nason Creek to its floodplain, and relocate human constraints. This project removed a levee, rerouted a powerline corridor, and restored creek habitat.  Rerouting powerlines created a new sinuous 0.6-kilometer channel alignment. The project also removed 0.7 kilometer of levee, created two backwater alcoves, planted three hectares of floodplain, and installed large wooden structures for fish habitat. This project protects critical infrastructure, improves habitat for salmon species, and reduces flood and erosion risk.
