Yukon Delta NWR · ADF&G Subsistence Priority Fishery

Alaska’s second-longest river and one of the most important subsistence salmon fisheries in North America. The Kuskokwim drains the west slope of the Alaska Range and flows through vast tundra to Kuskokwim Bay, supporting Yup’ik subsistence communities that depend on king, chum, and silver salmon. The upper river near McGrath and Nikolai holds sheefish, grayling, and rainbow trout, and the tributaries — Holitna, Aniak, Kwethluk — offer some of the most remote and productive fly-in fishing in Alaska. Access is by plane to villages; no road system reaches the river.
