Alaska Flood Watch | Effective 05/10/2026 15:05

* WHAT...Flooding caused by an ice jam is possible. * WHERE...Aniak, Kalskag, and Kwethluk * WHEN...Through Monday evening. * IMPACTS...Ice jams may result in flooding of rivers, creeks, sloughs, and other low-lying flood prone locations. Water may impound behind a jam which may cause flooding several miles upstream. * ADDITIONAL DETAILS... - For Aniak: As of Sunday afternoon, the River Watch Team reported an ice jam is still in place on Kuskokwim River downstream of Aniak near Birch Crossing. Jammed ice continues to remain tightly packed from the toe of the jam up to the gravel pit at Aniak. Water levels have decreased or remained fairly constant over the past 24 hours and this trend is expected to continue. For Kalskag: As of Sunday afternoon, the River Watch Team reported that ice near Kalskag has started to move. Meanwhile, ice downstream of Kalskag through to the mouth of Bogus Creek remains relatively healthy and intact. The Old River near Kalskag is currently a mix of open water and ice. Because of the ice jam upstream and intact ice downstream, Kalskag faces a heightened flood threat. Residents of Kalskag should remain alert to changes in ice and water levels. For Kwethluk: Ice jammed in the lower Kuskokuak channel at and just upstream of the Y, or confluence with the Akiak Channel of the Kuskokwim, has resulted in water rising in and near Kwethluk. River Watch aerial reconnaissance noted water has already started inundating surrounding low-level areas near the community. Aerial reconnaissance also noted that there are several spots of open water in the upper portion of the Kuskokuak Channel, as well as downstream beyond the Y. Until the ice shifts or moves, residents should prepare for continued rising water levels, particularly in flood-prone lower areas. - Http://www.weather.gov/safety/flood
