The Upper Reservoir at the Taum Sauk Pumped Storage Plant has been breached flooding the Black River and creating havoc and washing out roads and buildings downstream.
The washout forced the evacuation of the superintendent’s office at Johnson Shut In’s State Park and forced the evauation of Lesterville.
The plant was built in 1963 atop Taum Sauk Mountain, Missouri’s highest peak. Officials at AmerenUE, a utility based in St. Louis, said the breach occurred at the northwest corner of the reservoir that holds back 1.5 billion gallons of water from the Black River. It wasn’t clear why the breach occurred, but AmerenUE officials said there was no obvious equipment failure, nor was there evidence of foul play.
