Why is WSDOT
replacing culverts under State Route 112 at Joe Creek in Clallam County?
WSDOT is removing two culverts under State Route 112 at Joe Creek to improve fish passage. The existing culverts are a fish barrier. Replacing the culverts will make the stream more maneuverable for salmon that spawn in the creek, extending usable habitat.
WSDOT's Fish Passage Barrier Removal Program identifies and removes barriers to fish passage caused by culverts under state highways. In 2013, a federal court injunction required the state to significantly increase the state’s efforts to remove state-owned culverts that block habitat for salmon and steelhead.
WSDOT has a responsibility to be a good environmental steward. The culverts run under state highways and must be replaced to bring them up to current standards and eliminate the barrier they pose to fish.
The End Result
The wider culvert with a gravel streambed inside the structure simulates a natural streambed under the roadway. It will improve fish habitat by slowing the velocity of the stream, increasing habitat area, and create more pools and eddies for fish. The gravel channel will be conductive for fish passage to upstream habitat.
This project replaces outdated culverts that are a barrier for fish with culvert corrections that are built wider than the existing stream channel and are sloped at a similar grade as the natural stream. The wider, man-made culverts simulate what is found in a natural stream bed. Once finished, salmon will be able to migrate to and from habitat areas without having a barrier at SR 112.
What is the project timeline?
All in-stream construction for Joe Creek will take place during the approved time frame for in-water work while minimizing effects on the fish.
To replace the existing culverts, a deep open trench will be excavated across SR 112 at Joe Creek all at once. The process of excavating, installing a new structure, and backfilling takes multiple days.
