Puyallup River Revetment

State/Territory:

The Puyallup River in Washington state is channelized and disconnected from its floodplain due to levee construction and logging in the region. This has led to habitat degradation for important fish species and a higher risk of flooding and damage to important transportation infrastructure. This project will reconnect over 28 hectares of the floodplain and remove 800 meters of an existing levee. This project will also install engineered logjams to encourage channel braiding and form habitat, and discourage channel avulsion toward the nearby road. This project creates valuable habitat for three salmonid species that are financially and culturally important to the region.
