Residents of Edenville and Sanford in Mid-Michigan have been ordered to evacuate after the breach of two dams, prompting Gov. Gretchen Whitmer to declare a state of emergency for the area.

Downtown Midland could be under nine feet of water – historic water levels from flash flooding – according to the governor.

So far, 10,000 people have been evacuated or are in the process of being evacuated, the Community Affairs Director for the City of Midland Selina Crosby Tisdale told 7 Action News Wednesday. The process have been going smoothly as residents have taken requests seriously.

There are about 42,000 people in the city and around 70,000 total in the county.

According to Tisdale, they are calling this a 500-year flood. A 1986 flood hit historic level at about 33.9 feet. Officials are expecting Tittabawassee River levels to reach around 36 feet later Wednesday morning. Typically, a flood emergency declaration is made when water levels hit 20 feet.
