King County designed, permitted, and constructed a habitat restoration project on Boise Creek in a predominantly agricultural area. Historic stream and floodplain drainage activities have included extensive stream channelization, channel dredging, and placement of drain tiles to expand agricultural areas. This has resulted in channel entrenchment, gravel embedment, sidecast spoil terraces, and the removal of riparian vegetation and instream wood. King County is completing a feasibility analysis and conceptual design for future restoration projects to be implemented along Boise Creek from River Mile 1 to 3. King County completed: a) a permit-ready design; b) construction of a streambank restoration pilot project; and c) riparian restoration. Acquisition of property was paid for by King County outside of this grant. King County will monitor the project and maintain the project for at least five years following construction. The goal of this project is to restore fish habitat (in particular, slow water margin habitat) and improve water quality in a degraded reach of Boise Creek. Specific objectives are to: a) place wood in the riparian zone, including the stream; and b) revegetate the riparian zone with native trees and shrubs. This project significantly benefitted Chinook and steelhead, and in particular White River spring Chinook, which spawn and rear in Boise Creek. They are the only spring population in south Puget Sound and are genetically the most distinctive stock in south and central Puget Sound. Approximately one mile of livestock exclusion fencing was installed.
