Document Description
Construct a 15.3-million-gallon off-stream pond on the Marshall Ranch, adjacent to Redwood Creek, a tributary to the South Fork Eel River. This Project seeks to improve habitat for coho salmon and steelhead in Redwood Creek, an important salmon bearing tributary, by addressing the limiting factor of low summer streamflows. The pond has been sited and designed to fill during the winter wet season and release most of its stored water directly to Redwood Creek providing increased flows of 50 gallons per minute during the 5-month dry season. It is anticipated that the pond will be nearly drained at the end of each dry season for bull frog management. The Project also includes cooling gallery, associated infrastructure, erosion control, instream habitat enhancement structures, and a solar energy generation system to operate the Project.
