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 September 30, 1935, President Franklin D. Roosevelt dedicated the Hoover Dam, telling the 10,000 people gathered at the ceremony that it was a “great feat of mankind” destined to reshape “the geography of a whole region.” The American Society of Civil Engineers calls it one of the “Seven Modern Civil Engineering Wonders.” In honor of this significant milestone for this fantastic structure, I’ve collected some facts and figures, news articles, information on the bypass bridge, and some concerning news about the future of the dam’s ability to supply power.
