About

At 225,000 CFS average flow through 1,980 miles of Alaska wilderness, the Yukon River moves more water than any other North American river system north of the Columbia. The upper section from Eagle to Circle covers 155 miles of protected wilderness float through Yukon-Charley Rivers National Preserve, historically the domain of king and chum salmon runs. The middle stretch from Tanana to Galena spans 300 miles where subsistence and sport fishers target silver salmon, while the lower 500 miles from Holy Cross to Emmonak constitute one of Alaska's most important commercial and subsistence fisheries within Yukon Delta National Wildlife Refuge.

For millennia, Athabascan and Yup'ik peoples built their cultures around salmon trading networks along these corridors. The 2021 king salmon collapse forced unprecedented fishing closures across multiple sections, highlighting the river's role as Alaska Department of Fish and Game's highest subsistence priority fishery. Class I-II water at optimal flows between 100,000-500,000 CFS makes this accessible to experienced wilderness paddlers, though the scale demands serious expedition planning. Yukon River Lodge operates out of Eagle for those seeking guided access to the upper wilderness sections.

Data Quality

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.
