| Brief Description | Flood Warning | |
| Detailed Description | Mendenhall Lake gauge levels along with the images and water levels from Suicide Basin indicate that the basin has started its release of water into Mendenhall Lake. A crest will be early Tuesday morning near record values of 15ft. * WHAT. Flooding caused by a glacier-dammed lake outburst continues. * WHERE. The Mendenhall Lake and River near Areas Around The Glacier Visitor Center, The Mendenhall Campground, Skaters Cabin Road, View Drive And locations Below Back Loop Bridge. * WHEN. Until 400 PM AKDT Tuesday. * IMPACTS. Flooding of flood-prone locations along the Mendenhall Lake and River is imminent. * ADDITIONAL DETAILS. - At 649 PM AKDT, river gauge reports indicate rises in water levels from a glacier-dammed lake outburst across the warned area. The rate of the decrease in the basin is increasing so expect the Mendenhall Lake and River to begin rising more rapidly. Flooding is expected to begin shortly, especially near the Mendenhall Lake and River. - The outburst flood forecast is based on an estimated volume of water in the glacier dammed lake and an estimated release rate based on previous events. The extent of water drainage within the basin (partial or full) can vary widely between outburst flood events and is a major source of uncertainty in the forecast, particularly with regard to the peak flood stage. - For Mendenhall Lake : At 6:15pm the stage was 5.8 feet. Flood Stage is 9.0 feet. Forecast: A near record crest around 15.0 feet is expected around 4:00am Tuesday. Water levels will go above minor flood stage around 10:00am Monday.
