What dam broke in Idaho?
Teton Dam
On June 5, 1976, Teton Dam in southeastern Idaho catastrophically failed. Early that Saturday morning, bulldozer operators tried in vain to plug seepage holes on the downstream face of the dam. By 11 a.m., a torrent of water ripped through the dam, releasing more than one million cubic feet per second.
What was the cause of the failure of the Teton Dam in 1976?
Teton Dam, a 305-foot high earthfill dam across the Teton River in Madison County, southeast Idaho, failed completely and released the contents of its reservoir at 11:57 AM on June 5, 1976. Failure was initiated by a large leak near the right (northwest) abutment of the dam, about 130 feet below the crest.
What happened when the Teton Dam failed?
When the dam failed, the flood struck several communities immediately downstream, particularly Wilford at the terminus of the canyon, Sugar City, Salem, Hibbard, and Rexburg. Thousands of homes and businesses were destroyed. The small agricultural communities of Wilford and Sugar City were wiped from the river bank.
How many men died building Glen Canyon dam?
18 workers
During construction of Glen Canyon Dam, 18 workers died in various kinds of accidents. All of the bodies were recovered and accounted for and no one was buried inside the dam.
