My post yesterday about the removal of older, unmaintained dams became today's news in Michigan.
The Edenville Dam, built privately in 1924, had been owned and operated by Boyce Hydro Power. In 2018, their permit to operate had be revoked when a survey of the dam noted structural deficiencies and design flaws that made it vulnerable to a high water event. The spillways were only capable of shedding about 50% of the anticipated water. As water built up in the reservoir, pressure on the back side of the earthen dam would exceed the strength of the dam and a catastrophic failure was deemed possible.
Late yesterday afternoon, this predicted event occurred. 2.9 billion cubic feet of water were released into the Tittabawassee River. Wixom lake was drained. Here's footage during and then after.
