DESCRIPTION
This project is located on a large tributary to the Skokomish River in central Mason County named Vance Creek. Vance Creek originates in the foothills of the Olympic Mountains and historically supported abundant coho, chum, Chinook, and steelhead runs. Due to numerous anthropogenic actions including logging, road building, and removal of large woody debris (LWD) the status of Vance Creek as a salmon producer has changed as the salmon stocks have suffered substantial losses. This project is located at approximately river mile 1.9 and aims to improve the riparian function and in-stream habitat complexity in this reach of Vance Creek. We intend to reach these goals through the installation of many LWD pieces including an engineered instream logjam and planting a native riparian buffer. The LWD structures will increase habitat complexity in the channel, create pools, and temporarily arrest bank erosion to allow the riparian planting to mature in order to restore natural riparian function.
This project has been specifically identified by the Vance Creek Geomorphology and Modeling Report completed by the Bureau of Reclamation through the Army Corps of Engineers Skokomish General Investigation. The installation of LWD in mainstem Vance Creek has been identified by the Hood Canal Coordinating Council's Three-Year Watershed Implementation Priorities Plan. Additionally, this project addresses limiting factors presented by the Summer Chum Salmon Recovery Plan, Chinook Recovery Plan, and the WRIA 16 Limiting Factors Analysis.
