The Teton Dam was a feerally built earthen dam on the Teton River in southeastern Idaho in the United States which existed for less than one year before suffering a catastrophic failure on June 5, 1976. The collapse of the dam resulted in the deaths of 11 people and 13,000 head of cattle. The dam cost about USD $100 million to build, and the federal government paid over $300 million in claims related to the dam failure. Total damage estimates have ranged up to $2 billion. The dam was never rebuilt.
