Flood Warning
Issued: 9:59 PM Jun. 17, 2025 – National Weather Service
...FLOOD WARNING FOR SNOWMELT REMAINS IN EFFECT UNTIL 4 PM AKDT FRIDAY... * WHAT...Flooding caused by snowmelt continues. * WHERE...Colville near Umiat To The Mouth Of The River. * WHEN...Until 400 PM AKDT Friday. * IMPACTS...High water from rapid snow melt and recent ice jams is leading to significant flooding along the Colville River. * ADDITIONAL DETAILS... - At 158 PM AKDT, Monday morning, water levels at the USGS Colville River gage at Umiat were at 62.94 ft and still rising. This is the highest on record by over 3 ft since the gage was established in 2003. Water has now inundated portions of the Umiat airstrip and is encroaching on structures in the camp. High water extends downstream to the Colville River Delta where several ice jams have formed over the previous 24-hrs, leading to flooding of the eastern floodplain. Once these ice jams release, communities and infrastructure downstream should prepare for and expect high water and flooding over the next couple of days. Water levels are expected to continue to slowly rise and level off through the end of the week as additional high elevation snow melt is expected to make its way downstream. - Http://www.weather.gov/aprfc PRECAUTIONARY/PREPAREDNESS ACTIONS...

The Dalton Highway remains closed between MP 305 and MP 356. The USGS river gauge at MP 325 has likely reached its peak and is now slowly receding. However, water levels are expected to remain above flood stage through Thursday. - High water will continue to move downstream over the coming days. Infrastructure near the river's mouth, including roads and bridges near the Deadhorse/Prudhoe Bay area is already being impacted. Water levels in this area are expected to gradually rise, particularly around high tide. - Motorists and local authorities are advised to monitor conditions closely and avoid flooded areas. - http://www.weather.gov/aprfc PRECAUTIONARY/PREPAREDNESS ACTIONS...
