The Lower Boise Creek Construction project will restore channel, floodplain, and riparian conditions at the mouth of Boise Creek, a right-bank tributary to the White River near river mile 23.3. The Creek was placed into its present-day alignment during the construction of adjacent road and railroad corridors. The road and railroad have been removed, and the property within the project area is now in public ownership. The project will relocate the lowest 500 feet of channel into a newly constructed channel approximately 1200 feet in length. The new channel will have a meandering pattern with no levees or revetments anywhere along its length, and it will restore the historic channel gradient and habitat. It will be designed to contain channel forming flows, but to allow out of channel flows and floodplain inundation during flood events. The current berm configuration that confines Boise Creek will be removed to restore a floodplain connection with the White River. Boise Creek is one of the most productive tributary salmon streams in the White River Basin for Chinook, Coho, and steelhead. The project fits well with the WRIA strategy since it is identified as a near-term priority in the Salmon Habitat Protection and Restoration Strategy for WRIA 10 and 12. Since this project occurs on easily accessible public land, next to a proposed regional trail, it provides a unique opportunity to promote public education relative to watershed health and salmon recovery.
