DESCRIPTION
The project is located on CDLT property adjacent to Nason river mile 2.3 and resulted in a perennial surface water connection to a 0.25 mile long relict oxbow. Pre-project, Nason Creek only activated this oxbow and the adjacent wetland with a surface water connection at the 25-year event. Construction included 1) excavation at the upstream and downstream end of the relict oxbow 2) placement of two in-stream log jams to increase flow activation at the upstream end and increase sediment flushing at the downstream end of the oxbow 3) placement of 24 habitat logs and 3 toe log structures within the oxbow 4) 0.15 acres of wetland rehabilitation , which included filling 125 linear feet of previously constructed ditches, de-compacting adjacent soils, and planting with native trees and shrubs 5) re-planting all work areas to achieve 7.5 ft. on center and 75% survival. This project was constructed in 2018 with implementation funding from BPA project #76713.
