In May 2020, heavy flooding resulted in the catastrophic failure of the Edenville Dam embankment, sending a wall of water downstream in the Tittabawassee River and completely draining Wixom Lake.

The conclusions of the report include a discussion of a relatively rare phenomenon in earthen dams. Let’s walk through the investigation to try and understand what happened.
