Project: Green Valley Wateshed Coho Migration Enhancement Project Design

Description: This project is necessary to improve the Green Valley Creek watershed which acts as habitat for the Coho Salmon as a migration corridor, as smelts leaving the rearing pools in the upper reaches can spend several months moving downstream feeding and rearing. While historically providing floodplain wetland habitat and back water alcoves needed for velocity refuge and food-rich foraging areas, lower Green Valley Creek now suffers from channel incision, homogenous bedform, and lack of floodplain connectivity. Funding for this project will be use to design improvements to the Green Valley Creek watershed that will allow for high flow refugia, reduce standing risk, improve habitat values, and restore connectivity to a 2.5 mile potential class 1 tributary. These efforts will provide an improved habitat for endangered Coho Salmon.

Reference Number: 3600BP1796004

Implemented By: North Coast Resource Conservation and Developement Council

Objective: The objective of the project is to design and plan efforts that when implemented will improve habitat conditions through key Coho Salmon migration corridors in the Green Valley Creek watershed, by facilitating access to the critical rearing habitat in its upper tributaries. The project will complete 100% designs forlarge-scale winter/spring rearing, migration, and high - flow refugia habitat for juvenile salmonids at three sites within the disconnected floodplains in the Green Valley Creek watershed.
