Madison Dam

Madison Dam is a hydroelectric dam on the Madison River in Madison County, Montana, in the southwestern part of the state.

The timber-crib dam was constructed in 1906 as a replacement for a similar 1901 dam and powerhouse on the same site. The dam is 39 feet (12 m) high and 257 feet (78 m) long at its crest, placed into the narrows of Bear Trap Canyon. As one of eight PPL Montana hydro projects, it has a generating capacity of 9 megawatts (12,000 hp) in a run-of-the-river configuration.[3] Montana Power Company acquired the dam in 1912 as part of a merger, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014.
