Description

This project will improve connectivity to, and enhance an existing 0.5 acre perennial on-stream pond and construct a large off-channel alcove, thereby providing approximately 40,000 sq. ft. of non-natal winter high-flow refugia and rearing habitat for coho salmon. We will also construct approximately 18 instream LWD structures along 1,600 feet of mainstem Ryan Creek within the project area.

Project Benefit

Increase connectivity to off-channel aquatic habitat that is currently mostly disconnected. Increase the area available for rearing and benefit juvenile coho salmon by reducing competition pressures and increase access to food sources and new aquatic habitat. Project may serve as rearing habitat during out-migrant periods even when flood flows are not occurring. Woody debris structures will be constructed to increase habitat complexity and cover for juvenile coho salmon.
