Project overview
This project removed barriers to fish migration under US 101 at six locations in Grays Harbor and Jefferson counties.
What to expect
In summer 2025, crews corrected culverts at six locations along US 101 on the Quinault Indian Nation.
This project removed barriers to fish at six locations along US 101 between Lake Quinault and just north of the Queets River.
A fish passage barrier is anything that hinders fish from moving upstream or downstream. Culverts or pipes under the roadway allow water to flow but may not allow fish to swim through. Culverts may block fish migration because the water flow is too swift, too shallow, or has a waterfall into or out of the culvert.
Since 1991, WSDOT has worked to improve fish passage and foster healthy waterways. This is done by removing barriers that keep fish and other aquatic species from moving under the state highway.
Since 2013, WSDOT has worked to follow the requirements of a U.S. District Court injunction to correct barriers to salmon and steelhead.
