This rolled earthfill embankment dam with a gravity concrete control section is 5,200 feet long and 95 feet high above the flood plain and was built in the 1960s to provide flood control. The plant is expected to produce enough electricity to power about 18,000 homes each year. This will be the first hydro facility Missouri River Energy Services develops.
