Description    


This project is located in the Little Washougal River approximately two miles upstream from the confluence with the mainstem Washougal River at RM 5. The primary objectives of the project are; Stabilize the stream banks by restoring the pattern, dimension, and profile of the stream channel for a distance of 7,500 LF. Remove invasive non-native plants and replace with native plants along 26 acres of riparian habitat in a buffer averaging 150 wide (total) and 7,500 LF long. Restore natural watershed functions that create and sustain good fish habitat.The focus of this proposal is to restore riparian and in-stream habitat conditions needed by salmonids in order to successfully spawn and rear in the lower Little Washougal River. The stream contains summer and winter steelhead, chinook and coho salmon, and resident and sea-run cutthroat trout.These objectives will be met by employing the use of rock J-vanes and large wood structures to stabilize the stream banks temporarily (<50 years) until the restored riparian vegetation matures. This proposal is supported by the WRIA 28 LFA and the Lead Entitys Interim Strategy For Habitat Protection and Restoration guide.After restoration, the riparian and in-stream habitat will once again provide the essential functions that will support the recovery of wild salmonids, including the maintenance of water quality, habitat diversity, connectivity, energy inputs, flood attenuation, and overall ecosystem stability. Stabilize the stream banks by restoring the pattern, dimension, and profile of the stream channel for a distance of 7,500 LF. Use of rock J-vanes and large wood structures to stabilize the stream banks temporarily (<50 years) until the restored riparian. Replaced 2 tidegates in upstream striucture with lighter gates to allow more flow into slough, one of which has a 2 x 2 fish door for continuous access. Replaced 5 tidegates in downstream structure with lighter gates to allow more flow.
