The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3 ), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3 ).
The dam's hydro power plant consists of three units that receive water from three different penstocks, located 865 feet (264 m) upstream. [8] In the early 21st century, with an installed capacity of 208 MW, [9] the dam provided enough power for about 147,000 homes and more than $9 million in annual revenue for the tribes.
Today, the four dams together impound an upstream reservoir, with a water storage capacity of 8,300 acre-feet (10,200,000 m 3), and a seven-unit hydroelectric generation capacity of 94 megawatts. [1] Montana Power Company originally built the dam, PPL Corporation purchased it in 1997 and sold it to NorthWestern Corporation in 2014. The island ...
The dam and the 134-mile-long (216 km) lake are owned and operated by the U.S. Army Corps of Engineers and exist for the purposes of hydroelectric power generation, flood control, and water quality management. [4] The dam presently has a nameplate capacity of 185.25 megawatts, divided among 5 generating units (which in turn are divided between ...
