DESCRIPTION
Sound Salmon Solutions (formerly Stilly-Snohomish Fisheries Enhancement Task Force) conducted a 30% design project for salmon habitat restoration for an approximately 1-mile reach of lower Jim Creek. Sound Salmon Solutions worked with The Watershed Company to conduct field investigations to assess habitat conditions and processes within the reach and develop conceptual designs (roughly 30% level designs) for future restoration projects. Restoration designs include: protection and enhancement of two existing log jams; placement of 14 large woody debris structures; removal of rip-rap and car-body bank armoring; and riparian corridor restoration through livestock exclusion fencing & setbacks, invasive vegetation control and native plantings. The eight adjacent landowners within the project area all participated in the design process, providing feedback on project concepts and discussing locations, access, and perceived risks of implementation. Hydrologic and preliminary hydraulic modeling of the proposed restoration activities were also completed as part of this work.
South Fork (SF) Chinook are considered to be at the threshold of extinction (Shared Strategy 2007), and Jim Creek is one of a few tributaries where SF Chinook are found (SIRC 2005). Habitat conditions within and adjacent to Jim Creek are sub-optimal for Chinook and other salmonids. The project resulted in designs for on-the-ground restoration actions that, when constructed, will contribute to improved habitat conditions for SF Chinook and other salmonids.
