This photo shows a view of a dam on Wixom Lake in Edenville, Mich., Tuesday, May 19, 2020.
The Edenville dam, in Michigan’s Gladwin and Midland counties, includes a series of earthen embankments totaling about 6,600 feet (2,012 meters) long, with a maximum height of nearly 55 feet (16.8 meters).
The Edenville dam's spillway capacity was only about 50 percent of the probable maximum flood, the commission said.
Among its other violations: performing unauthorized dam repairs and earth-moving and failing to file an adequate public safety plan, maintain recreation facilities or monitor water quality.
“The record demonstrates that there is no reason to believe that Boyce Hydro will come into compliance," the commission added.
