Suicide Basin update as of Tuesday morning

July 9, 2019 – News

Suicide Basin started overtopping the ice dam on Sunday, but subglacial drainage has not begun. It’s being monitored collaboratively by US Geological Survey, University of Alaska Southeast, National Weather Service, and the City and Borough of Juneau. It’s anticipated that subglacial drainage could happen within the next few days. Last year when it overflowed, it triggered the full release 24 hours later.

Suicide Basin is a side basin of the Mendenhall Glacier above Juneau. Since 2011, Suicide Basin has released glacier lake outburst floods that cause inundation along Mendenhall Lake and Mendenhall River.
