Tag: Navarro River

This project developed engineering plans for replacing a failing road crossing on Neefus Gulch — a tributary to the North Fork Navarro River in Mendocino County — with a stream simulation arch culvert, and for installing 14 large wood structures to arrest an active knickpoint in a severely incised 1,600-foot channel reach. The designs were part of a broader restoration effort that also removed an upstream earthen dam. Subsequent monitoring documented 10 coho salmon redds and two steelhead redds, including in reaches where salmon had not spawned for over 70 years.
