Coos Watershed Association

Challenge

Historical agricultural and timber industry land uses degraded salmon habitat beginning in the mid-1800s.

Project Overview

Reduced stream temperatures and improved fish passage for Coho Salmon.

The Coos Watershed Association began restoration and monitoring in Willanch Creek in 1995. Restoration actions included riparian plantings, road improvements, road decommissioning, fish passage projects and large woody debris placements. The creek is now 10-Fahrenheit degrees cooler. Water flowing through the creek and floodplain takes a more natural path, contributing to high quality fish habitat over time. Projects have restored critical Coho Salmon adult access to spawning grounds and juvenile access to the estuary.
