Two dams breached in Midland County, Michigan, causing flooding and the evacuation of 10,000 local residents after days of heavy rains. The Edenville Dam and the Sanford Dam both experienced “catastrophic dam failures” affecting the City of Midland about 8 miles downstream of the Sanford Dam. A Dow Chemical plan sits on the City’s riverbank as well. So far no injuries are reported, but there are many challenges associated with opening shelters in the midst of a pandemic. The governor of Michigan urged people to stay with friends or relatives or to go to one of the shelters. The Edenville Dam was built in 1924 and was rated in unsatisfactory condition in 2018 by the state.
On December 14, 2005, the upper reservoir of the Taum Sauk pumped storage plant, a hydroelectric power plant in the Missouri Ozarks, suffered a catastrophic failure. The resulting flood severely damaged the Jonhson’s Shut-Ins State Park and swept away the park superintendent and his family. Fortunately all of them survived.

Last week, the Missouri Attorney General’s office announced a settlement of $180 million between the facility’s owner, Ameren Corp. The failure reportedly was a result of negligence on the part of the company. More details after the break.
