Glacial Lake Outburst Flood - Mendenhall Glacier Area - August 15, 2025
The glacial lake outburst flood (GLOF) has ended and water is receding. The river crested around 8:00AM AKDT on Wed., August 13.
The US Forest Service has the following updates as of noon, August 15:
- The Visitor Center is OPEN regular hours (10:00AM-5:00PM, Sunday through Friday).
- All facilities and trails are open for regularly scheduled operations.
- West Glacier area - Toilets are undergoing maintenance and should be functional by Saturday morning, August 16. Outhouses at Skaters Cabin remain closed and are not expected to be available until later next week.
- The Back Loop Bridge is CLOSED FOR AN INDETERMINATE PERIOD OF TIME. Non-residents should avoid this area.
- Travel Juneau advises visitors to avoid the Mendenhall River and follow all posted signs and safety notices. We also ask that visitors avoid residential neighborhoods impacted by flooding.
What We Know — and What We Don’t
There is no need to cancel a reservation at this time. Some tour operators may choose to cancel or adjust tours near the glacier out of caution. Others — especially those taking place in unaffected areas — may not be impacted at all. Each business will assess conditions in real time, always prioritizing guest safety.
What You Can Do
- Please be patient. Many areas are still flooded. If you have booked an excursion or shuttle, your operator will call you directly. Operators are all local, will have the latest information, and if needed, will communicate with you. There is no need to cancel a reservation at this time.
- Wait for official updates from Travel Juneau, the city, the Forest Service, your tour provider, ship, or booking agent (ShoreEx).
- Trust your tour operators. They’ll keep your safety top of mind and communicate any changes directly.
- Stay informed by checking this page and following Travel Juneau on social media for real-time updates.
- Your flexibility and kindness mean a lot to us. Our community is preparing thoughtfully — and while we hope this won’t affect your time in Juneau, we also ask for patience and understanding. Last year, more than 300 Juneau residents were directly affected by flooding.
