Suicide Basin Monitoring and Current Conditions

 

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 multiple times each year with a record major flood event in the summer of 2023.

Current Status: 4/23/2024: The USGS got the primary camera up and running for the 2024 season last week (4/19) with the initial images available below. This coming season there will be some additional monitoring equipment installed by the USGS. The new equipment will provide increased situational awareness as there will be another time lapse camera, a gage within the basin to provide real time water levels and a weather station with temperature and precipitation information. 

Check back in May of 2024 for updates on the conditions within Suicide Basin.

Here is the NWS summary report from the major flooding event from the Suicide Basin glacier lake outburst flood in August 2023.

Images from the entire 2024 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.

Suicide Basin Level (Pool Height)

Graph showing the current (blue) pool height of Suicide Basin. These values come primarily from a pressure transducer, secondarily from a laser detection system, and can be estimated using the camera imagery if needed. Coming soon - awaiting USGS equipment installation.
