Suicide Basin is a side basin of the Mendenhall Glacier above Juneau, Alaska. Since 2011, Suicide Basin has released glacier lake outburst floods that cause inundation along Mendenhall Lake and Mendenhall River. Current Status: 10/27/2023: The battery for the camera in Suicide Basin died after the last image was taken on 9/26 and may not be fixed until next spring. Check back in the spring and summer of 2024 for updates on the conditions within Suicide Basin. UAS performed a drone survey of the basin on 08/08 to capture post-release imagery and elevation data. UAS, USGS, and NWS are in the process of evaluating the data from this major flooding event on the Mendenhall Lake and River. Here is the NWS summary report from the major flooding event from the Suicide Basin glacier lake outburst flood in early August. More information will be available here in the coming months. Images from the entire 2023 season can be viewed here.

Mendenhall Lake Stage Level
Graph showing the current (blue) and predicted (purple) stage level at Mendenhall Lake. Stage levels are annotated on the left y-axis on the graph. The graph also shows the Mendenhall River discharge (right y-axis), which is derived from the Mendenhall Lake stage level via rating curve. Once an outburst flood event begins, water levels rise at Mendenhall Lake and Mendenhall River. Drainage initiation at Suicide Basin and water level rise at Mendenhall Lake and River can be offset by several hours. |
