This project will eliminate five identified barriers for fish and open potential upstream habitat for improved migration. Also, the work will simulate what is found in a natural stream bed.
Why is WSDOT correcting fish passage barriers under US 12 and SR 8 between Montesano and east of McCleary?
Correcting fish passage barriers is an important part of the state's efforts to protect and restore fish runs negatively affected by outdated culverts under state highways.
In 2013, a federal court injunction required the state to significantly increase the state’s efforts in removing state-owned culverts that block habitat for salmon, bull trout and steelhead.
Replacing the outdated culverts with either bridges or fish passable structures will increase the likelihood of migration through the channels. Fish will be able to pass through creeks easier as the water will be slower, simulating a more natural creek environment.
In total, this project will replace five outdated culverts beneath US 12 and SR 8 that impede fish navigation:
US 12
SR 8
Two of these locations will be corrected with bridges, and the remaining three sites with concrete box culverts for improved fish passage.
Due to the extensive work required, this project will occur over a two-year period. All in-stream work will occur during approved Department of Fish and Wildlife's "Fish Windows" to minimize impacts to aquatic species.
The End Result
The existing stream channels will be graded to simulate natural streambeds for improved fish migration as identified in WSDOT's federal court injunction. The work in all five locations will open up several miles of potential upstream habitat for several fish species.
Total project costs will be published once a successful low-bid contractor has been selected.
