Hydrologic Outlook
National Weather Service Fairbanks AK
821 AM AKDT Thu Aug 28 2025

The headwater tributaries of the Koyukuk, Kobuk and Noatak Rivers
have received substantial rainfall in the last several days leading
to record crests at Slate Creek near Coldfoot (30 years of record)
and Dahl Creek near Kobuk (39 years of record). An additional 0.5"
to 1.5" of rainfall is expected to continue in the Western and
Central Brooks Range through Friday, keeping water levels on rivers
high and continued standing water in poorly drained areas.

The crests from the early week rainfall are making their way down
the main stems of the Kobuk, Koyukuk, and Noatak Rivers through the
end of the week. Expect river levels to remain high through the
weekend.
