The Garrison Dam was completed in 1954 and holds back the waters of the Missouri River creating the third largest manmade reservoir in the United States. The reservoir known as Lake Sakakawea is 178 miles long and up to 14 miles wide in places. The Garrison Dam itself is 2.5 miles long and 210 feet high and .5 miles wide at its base. The Garrison Power Plant is located directly below the dam on the West side.
The Garrison Power Plant is one of the many Hydroelectric Plants owned and operated by the US Army Corps of Engineers along the main stem of the Missouri River System. Our Power Plant is 522 ft long, 163 ft tall, and 134 ft wide on offers 5 power generating turbines that feed power to homes across multiple states.
