Flood in Lower Kuskokwim Valley, Alaska

Riverwatch crew identified an ice jam which was impounding water below Akiak, AK and rising water had impacts on roadways in the village.

Unusually cold weather kept ice coverage in place on rivers across Alaska in spring 2023 with breakup much later than normal. Ice started breaking up on the upper reached of the Kuskokwim River starting on May 4th when ice started showing movement at Nikolai. Ice continued to melt, move and jam into late May. A Flood Watch was issued for Red Devil on May 13 and additional flood watches would continue to be issued as ice jam flooding continued to threaten communities downstream until the ice jam threat passed on the Kuskokwim River, which was May 22, 2023. The is a continuation of the previous Kuskokwim episode in which the ice jam flooding extended past 5 days on the Kuskokwim River. A large ice jam would move through the lower portions of the Kuskokwim River from Kwethluck through Akiak and into Bethel along Browns Slough from May 19-22, 2023.
