Hydrologic Outlook
National Weather Service Fairbanks AK
940 PM AKDT Sat Aug 30 2025

As of 9 PM on Saturday, the Tanana River at Fairbanks has risen to
23.74 feet and water levels are still rising. Flooding impacts are
not expected at this time, but those near the Tanana River outside
of the dike may observe high groundwater levels. While it is still
somewhat uncertain exactly how much the Tanana will rise before
cresting and receding, river levels will likely approach 24 feet
either tomorrow or Labor Day. At this level, while no specific flood
impacts will be realized, bankfull conditions will be noted in the
vicinity of Old Richardson Hwy in Salcha, and water may begin to
spill over the bank and approach Ruger Trail near Bradbury Road.
Tanana River water has a history of beginning to flow into the
Piledriver Slough as well when river levels in the Tanana at
Fairbanks reach 24 feet. Additional rainfall amounts over the next
few days in Fairbanks and upstream areas are expected to remain
under a quarter of an inch. As such, any further rainfall this
weekend is not expected to bring additional impacts to locations in
Fairbanks near the Tanana.

The headwater tributaries of the Koyukuk, Kobuk, and Noatak Rivers
have received substantial rainfall this week leading to record
crests at Slate Creek near Coldfoot (30 years of record) and Dahl
Creek near Kobuk (39 years of record). The crests from the early
week rainfall are making their way down the main stems of the Kobuk,
Koyukuk, and Noatak Rivers.

Rain is expected to return Saturday afternoon with 1 to 2 inches of
additional rainfall expected through Tuesday. River levels are now
expected to remain high through the middle of next week.
