Description
This project has created 0.75 miles/3.1 acres of off-channel/floodplain habitat, reconfigured over 0.7 miles of stream, and installed 135 instream habitat features which created 55 instream pools. In addition, 41,250 cubic yards of material were moved, and 0.2 miles of levy were removed to construct these instream and off-channel areas. The 3.1 acres of floodplain and off-channel area was planted with 27 species of native plants.
Project Benefit
This project will allow coho access to complex backwater and seasonal wetlands throughout the winter rearing season not currently available. Large wood additions will provide improved cover, gravel sorting, and increase channel complexity while riparian enhancements through floodplain lowering and plantings will improve shading, food supply, and provide future large wood loading. This project directly addresses the major limiting factor for this core population identified in the NMFS Draft Recovery Plan (2012), a lack of off-channel rearing habitat, while improving conditions for all anadromous species and life-stages by breaching levees and restoring channel form and connectivity with the historic floodplain.
