DESCRIPTION
The Mashel River between RM 4.4 and 6.7 is an important spawning and rearing area for Chinook, steelhead, pinks and coho. Restoration is a priority in the Nisqually Chinook Recovery Plan (2001), and is supported by recent multi-species Ecosystem Diagnosis and Treatment (EDT) analysis (Nisqually Tribe 2004). Historic land use practices have created sedimentation problems and a lack of wood throughout the lower reaches of the Mashel River.
This assessment included development of a comprehensive subset of restoration projects for Reach 7 (confluence of the Little Mashel) and Reach 4 (across from Smallwood Park, adjacent to Mill Pond). These restoration projects include instream habitat enhancement, riparian treatments, riprap removal near the Mill Pond, and addressing sedimentation impacts due to a large landslide. SRFB funds will be used for developing restoration projects for these two reaches, developing final engineering design and cost estimates for those projects. This includes coordination with landowners, project partners and applying for permits. This project is directly connected to two previous funded SRFB projects on the Mashel River. The assessment project that was completed in 2004 with SRFB funds identified Reach 4 and 7 as high priorities. The information in this assessment will be incorporated in the development of the restoration concepts. This project complements the restoration work that was completed in Reach 1, 2, and 4 in 2006.
