2 Dams Fail in Michigan, Forcing Thousands to Evacuate [nytimes.com]:
Severe flooding struck central Michigan on Wednesday after two dams were breached and days of heavy rainfall, forcing the evacuation of thousands of residents and prompting officials to warn of life-threatening danger.
The failures on Tuesday of the Edenville Dam and the Sanford Dam, about 140 miles northwest of Detroit, led the National Weather Service to issue a flash flood warning for areas near the Tittabawassee River, with downstream effects expected from Midland to Saginaw overnight. Residents in nearby towns, including Edenville, Sanford and Midland, were evacuated.
Gov. Gretchen Whitmer said at a news conference on Tuesday that downtown Midland, with a population of more than 41,000, could be under nine feet of water by Wednesday morning.
[...]The Tittabawassee River was expected to crest at 38 feet by 8 a.m. Wednesday, more than four feet higher than its record of 34 feet set in 1986. The flood stage is at 24 feet.
Dow Chemical Company, based in Midland, has activated its emergency operations center and will be adjusting operations, Rachelle Schikorra, a spokeswoman, told The Associated Press.
