Michigan Dam Incident Response Review: An Analysis of the 2020 Edenville and Sanford Dam Failure Response   [open pdf - 5MB]

Alternate Title: Edenville and Sanford Dams Incident Response Review

From the Executive Summary: "On the evening of May 19, 2020, following several days of heavy rain, the Edenville Dam, located one mile north of Edenville, Michigan, failed. The resulting release of water subsequently caused the Sandford Dam, located a few miles downstream, also to fail. The record-breaking flooding caused by these dam failures caused widespread damage and destruction to buildings, homes, roads, utility infrastructure, and natural resources. More than 4,000 structures across the region were reportedly impacted by the floodwaters, with estimated losses of roughly $245 million. Fortunately, approximately 11,000 residents successfully evacuated the area with no serious injuries or loss of life reported. This Dam Incident Response Review examines the causes for these dam failures and identifies the actions taken by the dam owners and emergency managers as the situation developed. Examining this event highlights the causes behind these dam failures, but also provides key insights and lessons for other jurisdictions with dams. The cascading impact of the Edenville dam failure causing the Sanford dam failure shows the dependencies within a water management system and the importance of collaborating across watershed areas."
