REXBURG, Idaho — Half a century after one of the most devastating disasters in Idaho history, communities across eastern Idaho are pausing to remember the day the Teton Dam gave way and forever changed life in the region.
On June 5, 1976, the newly completed earthen structure failed catastrophically, sending approximately 80 billion gallons of water surging through the Snake River Plain. The collapse killed 11 people, displaced thousands of residents, and left entire communities buried under layers of mud. This week marks 50 years since that event, and the communities that lived through it — and rebuilt from it — are gathering to honor that shared history.
Survivors Recall the Shock of That Morning
For those who were there, the memory has never faded. Marilyn Short, whose husband was working at the dam at the time of the failure, described receiving the warning call with disbelief. “He said you need to evacuate, the dam is breaking,” Short recalled. “Dams just don’t break.”
Kurt Hibbert, who survived the flood and its aftermath, said the disaster stripped life down to what truly matters. “Things didn’t matter anymore,” Hibbert said. “Are your friends safe? Is your family safe?”
Both survivors’ accounts reflect a theme that has defined how eastern Idaho communities remember the disaster — not merely as a story of loss and destruction, but as a moment that revealed the depth of human connection and community resilience.
In the days and weeks that followed the collapse, the region faced an enormous recovery effort. Thousands of residents had been forced from their homes, and much of the valley was buried under debris and floodwater. Volunteers from across the region — and beyond — arrived in large numbers to help with cleanup and reconstruction, a response that became as central to the disaster’s legacy as the collapse itself.
Flood 50 Commemoration Spans the Week
Rexburg and communities throughout southeast Idaho are hosting a week-long series of events under the name Flood 50. The commemoration is organized around three themes: remembering the disaster and those affected, connecting with others who share the experience, and serving the broader community — reflecting the spirit of volunteerism that defined the original recovery.
The Flood 50 events aim to honor the generation that rebuilt the region and to ensure that the lessons of June 1976 are passed on to those who were not alive to witness them. Details on specific events and locations are available through local organizers.
Eastern Idaho’s civic identity has long been shaped in part by the Teton Dam collapse and the recovery that followed. The disaster tested the limits of what residents could endure — and demonstrated what they were capable of when working together. That narrative of resilience runs through the Flood 50 commemoration as much as the history itself.
Special Television Presentation Scheduled for Friday
A television special examining the dam’s failure and its long-term significance is set to air this Friday evening. The program, titled Teton Dam: The Failure and Future, will air at 9:30 p.m. on Fox and 10 p.m. on CBS for local viewers in eastern Idaho.
The special is hosted by reporter Linda Larsen and anchor Doug Long, and is expected to feature survivor accounts, historical footage, and broader context around the dam’s construction, failure, and the community response that followed.
What Comes Next
Flood 50 events are scheduled to continue through the week in Rexburg and surrounding communities across southeast Idaho. Residents interested in participating in the commemoration are encouraged to check with local event organizers for schedules and details. The 50th anniversary marks a significant milestone in how eastern Idaho collectively processes and preserves the memory of the 1976 disaster — one that fundamentally shaped the region’s character and continues to resonate with those who lived through it and those who have inherited its legacy.
