A flash flood occurred on August 26, 2026, with catastrophic results. The flood's destructive force was increased by a heavy load of debris. A blockage in the river, formed by a failure of ice, rock, and soil, is thought to have triggered the flood.

This blockage created a temporary dam that eventually breached, releasing a large volume of water and debris. The breach happened in the morning, around 8:30-8:37 a.m. Further details about the flood and its impacts are available.

The flood had significant human, physical, and economic effects. The flood's path and surrounding terrain contributed to its severity.
