DESCRIPTION
This fish passage project replaced two undersized culverts on Salmon Creek, tributary to White (Stuck) River and located in Sumner, Washington. Design for this project included replacing an existing 36-inch concrete culvert (Parker Road) and a 54-inch corrugated metal pipe culvert (Sumner Watershed) with two 8 x 16- foot concrete box culverts. This project created additional access to habitat for spawning salmon, opening up approximately 0.75 miles of upstream habitat from the mouth of Salmon Creek. Work was completed during a fish window and under the ordinary high waterline. Stream bed gravel was used to create spawning habitat for Salmon.
This project was a part of the City of Sumner's effort to improve Salmon habitat, by replacing undersized culverts along Salmon Creek. In 2009, two downstream culverts were replaced. This project sequentially replaced the next two culverts upstream, improving hydraulic capacity and reducing stream bank erosion.
Salmon Creek contains spawning and rearing habitat for Chinook, Coho, Chum and Pink Salmon. The Lower White (Stuck) River is a core region in the area's Salmon Recovery Plan.
