Teton Dam
former earthen dam on the Teton River in Idaho, United States
Teton Dam was a dam on the Teton River in Idaho, in the USA. When it was built, it was 3,100 feet (940 m) long and 305 feet (93 m) tall, making it one of the largest dams in the United States. It is most known for collapsing during spring runoff on June 5, 1976 a few months after it was completed. The resulting flood destroyed 10,000 acres of land and five cities.
The dam was never rebuilt. Although the U.S. Government paid $100 million to build the dam, it had to pay $300 million more dollars to pay for flood damages.
