Flood Advisory
In effect: Wednesday, Sep 16 2026 11:35 AM AKDT – Thursday, Sep 17 2026 1:00 PM AKDT
Issued by NWS Anchorage AK
FLOOD ADVISORY NOW IN EFFECT UNTIL 1 PM AKDT THURSDAY
What:
Flooding caused by onshore flow restricting Kuskokwim River
drainage in combination with excessive rainfall continues.
Where:
Lower Kuskokwim including Napakiak, Napaskiak, Oscarville,
Bethel, and Kwethluk.
When:
Until 100 PM AKDT Thursday.
Impacts:
Minor flooding in low-lying and poor drainage areas.
River or stream flows are elevated. Ponding of water in areas is
occurring or is imminent.
Additional Details:
- At 1130 AM AKDT Wednesday, the river gauge at Bethel indicates
water levels above flood stage, at or above 8.5 ft. Additionally,
reports out of the Lower Kuskokwim, including Napakiak,
Napaskiak, Oscarville, Bethel and Kwethluk, confirm flooding in
low-lying areas. Water levels may drop with the outgoing tide
this (Wednesday) afternoon, but are expected to rise again
Thursday morning with another high tide cycle.

These high water levels are a result of the Kuskokwim River
back-up at its outlet in combination with heavy rain runoff
farther upstream. Minor flooding will continue from overflow of
poor drainage areas. High tides will decrease later in the week,
allowing the backwater of the Kuskokwim River to drain, lowering
water levels to below flood stage.
- For Kuskokwim River at Bethel:
At 11:30am Wednesday the reading was 8.9 feet.
Flood Stage is 8.5 feet.

Impacts:
At 7.0 feet: Action and bankfull stage.
At 8.5 feet: Minor flood stage. Water starts to back up along Brown
Slough and flood low lying areas.

Instructions:
Stay tuned to further developments by listening to your local radio,
television, or NOAA Weather Radio for further information.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

If you live near or along Kuskokwim stay alert and be prepared to
take action.
Areas Impacted:
Interior Kuskokwim Delta
