Middle Boise CreekThe Middle Boise Creek Van Wieringen Stream Restoration Project is designed to increase the channel capacity and complexity in a reach of Boise Creek to create rearing and refuge habitat for Chinook and coho salmon and steelhead. Historically, Boise Creek was straightened and channelized through the project area, and streamside vegetation was removed. These actions limited habitat opportunities for young salmon. The proposed restoration project is consistent with the 2012 Puyallup Watershed (WRIA 10) Salmon Habitat Protection and Restoration Strategy. The project is intended to be built in the summer of 2018.

Project location

The project is located in a conservation easement on private property within the Enumclaw Agricultural Production District (APD) in unincorporated King County. The below map shows locations of several Middle Boise Creek Projects. (Click image to open as a PDF,  1.2MB).
