DESCRIPTION
The Larson's reach Phase 1 project was completed in the summer of 2001. The original concept called for 29 logjams, six were built due to funding constraints. We are proposing additional logjams in this area, as well as in the area above Larson's Bridge. Just downstream of the project, the Fobes Reach project constructed 14 logjams in the summer of 2010. Lummi Natural Resources has funds to conduct a hydraulic and geomorphic analysis from RM 20.7 to 23.9, looking at landslides in the area. In 2010, The Whatcom Land Trust completed a purchase of 80 acres in the floodplain in and area known as Elk Flats, around RM 22.6. LNR has been approved to receive a Centennial Clean Water grant for riparian restoration at Larsons, and the Whatcom Land Trust Property at RM 22.6. Habitat objectives for this phase include: 1) Create and improve pool habitat by placing engineered wood logjams in the cool water refuge areas of the Roaring/Plumbago Creek confluence 2) Increase habitat quality and diversity throughout the reach by placing engineered logjams to encourage scour pool formation, promote stable vegetated island formation, increase the availability and retention of spawning sized material, and increase available cover; 3) Increase the stability of existing mid-channel islands by constructing additional logjams; 4) Reduce incision in the reach through the placement of a channel spanning logjam which will aggrade the bed and reduce upstream shear stress.
