This is a design project for factors thought to most limit salmon survival in the Lower Elwha River floodplain downstream of river mile 1.5. The project is complementary to the larger effort to restore salmon populations in the Elwha Watershed under the Elwha Fisheries and Ecosystem Restoration Act and Puget Sound Chinook Recovery Plan. Fisheries activities are guided by the Elwha Fish Restoration Plan (Ward 2008). Chapter 8 of that plan recommends a number of restoration strategies including dike removal and large wood projects in the lower river floodplain. Since 2000, the Lower Elwha Klallam Tribe has led restoration efforts in the Elwha River and has focused on reach scale restoration between river mile 1.0-3.5. In this reach 4 dikes have been removed, 50 engineered logjams constructed, 4 side channels loaded with large wood, 50,000 native trees and shrubs have been planted, and noxious weeds removed. Completion of this project will result in a completed final restoration design in the lower 1.5 miles of the Elwha River floodplain.
