DETROIT – About 10,000 people in Mid-Michigan have been asked to evacuate their homes after multiple dams were breached, causing a major flooding emergency.

For the second time in less than 24 hours, families living along the Tittabawassee River and connected lakes in Midland County were ordered Tuesday evening to leave home. By Wednesday morning, water that was several feet high covered some streets near the river in downtown Midland, including riverside parkland, and reaching a hotel and parking lots.

As of 7 a.m. Wednesday, the Sanford Dam has been breached, but has not broken. But damage in Sanford could already be seen.

Gov. Gretchen Whitmer declared a state of emergency in Midland County late Tuesday night, urging residents to see higher ground as water levels were rapidly rising.

Gov. Whitmer said Downtown Midland, a city of 42,000 about 8 miles downstream from the Sanford Dam, faced an especially serious flooding threat. Dow Chemical Co.'s main plant sits on the city’s riverbank.

“In the next 12 to 15 hours, downtown Midland could be under approximately 9 feet of water," the governor said. "We are anticipating an historic high water level.”

“This is unlike anything we’ve seen in Midland County,” she said. ”If you have a family member or loved one who lives in another part of the state, go there now."

The Tittabawassee River was at 30.5 feet (9.3 meters) and rising Tuesday night - flood stage is 24 feet (7.3 meters). It was expected to crest Wednesday morning at a record of about 38 feet (11.6 meters).

Emergency responders went door-to-door early Tuesday morning warning residents living near the Edenville Dam of the rising water. Some residents were able to return home, only to be told to leave again following the dam’s breach several hours later. The evacuations include the towns of Edenville, Sanford and parts of Midland, according to Selina Tisdale, spokeswoman for Midland County.

History of the dams

The Edenville Dam, which was built in 1924, was rated in unsatisfactory condition in 2018 by the state. The Sanford Dam, which was built in 1925, received a fair condition rating.

Both dams are in the process of being sold.

In 2018, the Federal Energy Regulatory Commission revoked the license of the company that operated the Edenville Dam due to non-compliance issues that included spillway capacity and the inability to pass the most severe flood reasonably possible in the area.

There were 19 high hazard dams in unsatisfactory or poor condition in Michigan in 2018, ranking 20th among the 45 states and Puerto Rico for which The Associated Press obtained condition assessments.
