Hydrologic Outlook
National Weather Service Anchorage AK
351 PM AKDT Wed Sep 9 2026

...ELEVATED WATER LEVELS ALONG KUSKOKWIM AND JOHNSON RIVERS ON
THURSDAY AND FRIDAY...

Hydrologic Concerns:
* High water flowing down the Kuskokwim River, in combination with
  storm surge pushing up the up river, could cause water levels to
  rise between bankfull and minor flood stage.
* The highest water levels would occur if the downstream high water
  flow, storm surge, and high tide all occurred simultaneously.

Potential Impacts:
* More likely scenario: Bankfull conditions with no flooding
  expected.
* Worst case scenario: Nuisance flooding in low-lying areas.

Locations:
* Along Kuskokwim River, from Bethel south to Napakiak.
* Along Johnson River, from Nunapitchuk and Kasigluk south to the
  Kuskokwim River.

Timing:
* Highest water levels will likely occur around high tide on Friday,
  from about 11 AM through 4 PM.
* Strongest winds (south to southwesterly, gusting up to 30 to 45
  mph) from about 4 PM Thursday through 4 PM Friday.

Next Steps:
* Monitor the forecast for updates.
* Be prepared to take action in case of minor flooding.
