Description    


The Nez Perce Tribe will implement a habitat restoration project on a 0.21-mile segment of Lapwai Creek located in Culdesac Canyon located north of Winchester, Idaho. Current conditions include an unstable and highly incised creek segment confined by State Highway 95 that contains no instream woody material, a disengaged floodplain as a result of headcutting and stream incision, and very little riparian vegetation.

Project actions prescribed to increase habitat capacity for juvenile steelhead include: 1) construct new alignment for Lapwai Creek to increase stability and sinuosity, 2) install instream wood and rock structures and a weir to provide channel structure, roughness, and complexity, 3) construct floodplain grading to increase the lateral floodplain connectivity, 4) riparian plantings of native species, and 5) weed treatment.

Project Benefit    


Completing this habitat restoration project will provide a stable and complex channel that provides spawning and rearing habitat for ESA-listed steelhead (Oncorhynchus mykiss). Stabilizing this reach of Lapwai Creek and restoring natural stream processes and functions will increase the availability of high-quality rearing habitat for juvenile steelhead. Improving the current condition by increasing channel complexity, increasing quantity and quality of native fish habitat, especially cover and pools, increasing channel stability, and increasing the native extent and density of the riparian community will result in improved survival for all freshwater juvenile life stages. Furthermore, the reach of Lapwai Creek where the proposed restoration project is to occur holds the highest density of juvenile steelhead in the Lapwai Creek watershed (Chandler & Parot, 2003), and was ranked by Lapwai Creek Watershed Ecological Restoration Strategy (Richardson, Rasmussen & Chandler, 2008) as the highest priority area for targeting restoration to improve steelhead habitat and populations.
