HistoryEdit
The dam was built in 1914 and created Hebgen Lake. After the 1959 Hebgen Lake earthquake, the dam was damaged but it was fixed several weeks later. On August 30, 2008, two of the dam's four hydraulic gates failed, releasing 3,400 cubic feet (96 m3) per second of water into the Madison River. The normal discharge of the dam is 900 cubic feet (25 m3) per second and the gate failure caused a 1-foot rise in the river.
