Rising flood waters, already as high as five feet, submerged parts of the central MI of Michigan on Wednesday after days of heavy rain led to the failure of two dams and the evacuation of thousands of people.
Videos and images captured by witnesses show just how much water was unleashed when Michigan's Edenville Dam failed.
Midland City Manager Brad Kaye says the flood could leave part of the city under nine feet of water.
The Edenville Dam is northwest of Midland, MI, on Wixom Lake in Gladwin County.
Both the Edenville Dam and the Sanford Dam, which were breached, were built in the 1920s and are now being sold off after Edenville Dam's operators had their licenses revoked by the Federal Energy Regulatory Commission in 2018.
About 10,000 people in central MI have been forced to evacuate.
In a statement, Dow said it had activated its flood preparedness plan which includes the safe shutdown of operating units.
"We are anticipating the height being around 8 o'clock tonight", Whitmer said during a press conference.
Sias, 45, said emergency alerts then began coming on her mobile phone and people started calling to make sure she was safe.
Emergency crews are working to evacuate residents along the Tittabawassee River south of the Edenville Dam after it ruptured Tuesday. Others were asked to go to one of the shelters that were opened across the county.
As the scale of damage becomes clearer, Whitmer said her administration is investigating how the dams failed and who was responsible. The Sanford Dam, which was built in 1925, received a fair condition rating.
The Tittabawassee River was at 30.5 feet (9.3 meters) and rising Tuesday night-flood stage is 24 feet (7.3 meters). The Edenville Dam, built in 1924, was rated in unsatisfactory condition by MI in 2018 and the Federal Energy Regulatory Commission revoked the license of its operator, The Associated Press reports. Both dams are in the process of being sold.
The Weather Service issued flood warnings because 4 to 7 inches (10.2 to 17.8 centimeters) of rain has fallen since Sunday.

Huawei said the U.S. was "leveraging its own technological strengths to crush" foreign companies. This goes against the United States government's claim that it is motivated by network security.
