  • Ah-Di-Na Area Closure

    Portions of AH-DI-NA area is closed to to protect the endangered Sacramento River winter-run Chinook salmon eggs and fry in this area on the Shasta Lake Ranger District.

    The Winnemem Wintu Tribe, California Department of Fish and Wildlife, and the National Marine Fisheries Service have partnered to conduct a research/recovery project of this salmon species on the McCloud River. Fertilized winter-run Chinook Salmon eggs sourced from the Livingston Stone National Fish Hatchery will be stored in remote site incubators or Nur Nature-Base incubation equipment on the banks of the McCloud River adjacent to the Ah-Di-Na Campground. This pilot project is a test to determine feasibility of returning salmon to historic spawning grounds in the McCloud River, using assisted migration practices. This closure is necessary to protect the research equipment, prevent the potential for disruption of the study, and protect the growing winter-run Chinook salmon.
