The National Park Service is advising people to be cautious downstream of Bear Glacier due to flooding caused by the draining of an ice-dammed lake located seven miles above the terminus of Bear Glacier. The service said on Monday that the ice-dammed lake began draining last week based upon photographs from a remote camera in the area. No eyewitness reports have been received.
Historically such events have produced ice calving from the glacier with ice chunks as large as six feet in width above the water surface as well as less visible smaller ice pieces which could cause significant damage or injury to boats and passengers.
“Draining of the ice dammed lake can create hazardous boating conditions that might include: an increase in iceberg calving at the terminus of Bear Glacier, standing waves and strong currents, or the redistribution of sediment and debris in channels like the one that exists at the outlet of the lagoon,” said the service in a press release.
The Park Service advises extra caution in Resurrection Bay where floating ice may be present indefinitely.
