The Teton Dam, a federally built earthen dam on the Teton River in southeastern Idaho, collapsed during its first filling on June 5, 1976. The largest dam disaster in US History, it resulted in the deaths of 11 people and 13,000 head of cattle. Total damage estimates have ranged up to $2 billion.
However, now rebuilding of the Teton Dam is being revisited. Over $400,000 has been dedicated by the state of Idaho to conduct a study to determine the feasibility of rebuilding the dam.
