741 AM AKDT Tue Sep 2 2025

...FLOOD WATCH FOR THE SKILAK GLACIER-DAMMED LAKE RELEASE IN EFFECT
THROUGH SUNDAY MORNING...

* WHAT...Flooding caused by the Skilak glacier-dammed lake release
  is possible.

* WHERE...Skilak Lake and the Middle Kenai River near Skilak Lake
  and the Kenai River Downstream of Skilak Lake.

* WHEN...Through Sunday morning.

* IMPACTS...Kenai River level forecasts: Currently expecting the
  Kenai River to rise steadily at Skilak Lake outlet another 2 feet,
  cresting at moderate flood stage Friday or Saturday. At the Kenai
  Keys, expecting the Kenai River to rise another 2 to 2.5 feet,
  cresting just below moderate flood stage of 12 feet Friday or
  Saturday. Down river at Soldotna, expecting the Kenai River to
  rise steadily through week, cresting Saturday above bankfull
  levels near 12 feet.

IMPACTS: Expect steady river level increases next 4 days on lower
Kenai River. Flooding of low lying areas in the Kenai Keys area,
boat dock issues and extended period of high water and bankfull
conditions is likely.

Excessive runoff may result in flooding of rivers, creeks, streams,
and other low-lying and flood-prone locations.

* ADDITIONAL DETAILS...
  - Skilak Glacier Dam Lake is likely releasing. This combined
    with recent significant rain in the upper Kenai River basin
    will cause Kenai river levels to rise steadily from the
    outlet of Skilak Lake to the mouth through the end of this
    week. Some uncertainty exists due to recent rain as to when
    the Skilak Glacier Dam lake began releasing which could
    impact the crest timing and height. Planned aerial
    reconnaissance of Skilak Glacier Dam Lake will confirm
    whether a release has taken place and the extent of any
    release.
