US 12 - Unnamed Tributary to Wynoochee River - Remove Fish Barrier

Status

February 2018

  • Crews will replace an undersized culvert that is a barrier for fish. Workers will install a new larger culvert intended to improve fish passage and replicate a natural stream.
  • The current undersized culvert runs under both directions of US 12 just west of Montesano.
  • WSDOT will keep traffic moving as traffic will be reduced to one lane in each direction around the clock for about three months.

Why is WSDOT replacing the culvert under US 12 near Montesano
The existing culvert that sends this stream under both directions of US 12 west of Montesano is a barrier to fish passage. The small culvert will be replaced with a larger box culvert to improve stream flows for migratory fish.

This work is part of WSDOT's Fish Passage Barrier Removal Program, which 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 in removing state-owned culverts that block habitat for salmon and steelhead.

The End Result
The fish passage project will help restore the stream bed to a more natural state and improve fish passage for local migratory fish.

Project Benefits

  • This project will improve fish passage and open potential fish habitat.
  • The work will help WSDOT comply with the U.S. District Court ruling regarding fish passage.
