This $260,000 Cooperative Agreement awarded by the U.S. Department of the Interior's Fish and Wildlife Service under the Partners for Fish and Wildlife Program (CFDA 15.631) will fund the removal and replacement of an undersized culvert on Little Grass Valley Creek in Weaverville, California. The new 13x10 elliptical culvert will provide full, unimpeded fish passage for anadromous species like coho salmon, steelhead, and Pacific lamprey to access five miles of cold water spawning and rearing habitat. The project will also improve the overall hydrologic and geomorphic functionality of the stream crossing, reducing the risk of erosion or catastrophic events. The Northwest California Resource Conservation & Development Council, a non-profit organization, will lead this multi-year habitat restoration effort in collaboration with the California State Coastal Conservancy and the Fish and Wildlife Service's Partners for Fish and Wildlife Program.

This project will fund the removal of the existing undersized and failed culvert on little grass valley creek, a tributary to the trinity and klamath rivers, and replace IT with a properly-sized 13X10 elliptical culvert with an embedded bottom. This new structure will provide full, unimpeded fish passage for all species and life stages of anadromous fish to five miles of cold water spawning and rearing habitat. In addition, the project will substantially improve hydrologic and geomorphic functionality at this stream crossing, as well as substantially reduce the risk of accelerated erosion or a catastrophic mass-wasting event that is presently occurring with the existing stream crossing. This project will benefit the following anadromous fish species: coho salmon (sonc ESU ESA federally threatened, california cesa threatened), steelhead (klamath mountain province ESU, california species of concern), pacific lamprey (tribal trust species, california species of concern). The project is a collaboration between the northwest california resource conservation and development council, the california state coastal conservancy, and the service S partners for fish wildlife program and national fish passage program.
