Kobuk River
About
Through the heart of Alaska's Arctic, the Kobuk River flows 347 miles from the Brooks Range to Kotzebue Sound at an average 6,500 CFS — optimal flows range from 2,000 to 15,000 CFS depending on snowmelt and summer rains. The Iñupiaq Kobuk River Peoples have lived along these waters for millennia, and their subsistence fisheries still operate throughout the lower 147 miles from Ambler to the sound. The upper 110 miles from Walker Lake to the village of Kobuk runs through true wilderness within Gates of the Arctic National Park, while the middle 90 miles from Kobuk to Ambler moves through prime sheefish country. Kobuk Valley National Park, established in 1980, protects key sections of the drainage along with its famous sand dunes. The river carries National Wild & Scenic designation and flows mostly Class I-II water, though Arctic conditions and remoteness make this a serious undertaking. Arctic Wild operates guided trips for those who lack the logistics to manage resupply and evacuation on their own.
River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
