MIDLAND, MICHIGAN (REUTERS) - Rising floodwaters unleashed by two dam failures submerged parts of the central Michigan town of Midland on Wednesday (May 20), displacing thousands of residents and threatening to inundate a Dow Chemical Co plant in the riverfront city.
By late morning, floodwaters had reached the grounds of the Dow facility and were confirmed to be "comingling with on-site containment ponds", the company said in a statement, adding no employees had been hurt.
The National Weather Service (NWS) warned of "life-threatening" flooding as water levels of the Tittabawassee River in Midland, about193km north-west of Detroit, rose to historic levels.
"Never in my whole life have we seen the dam fail," said Mr Mark Bone, 53, a business owner and chairman of the Midland County Board of Commissioners.
"It flooded real bad in '86, but never like this."
Even as flooding submerged parts of Midland, the county seat and home to some 42,000 residents, under 1.5metres of water, Mr Bone said no injuries or deaths had been reported.
With authorities already grappling with the coronavirus pandemic, Governor Gretchen Whitmer on Wednesday called on the federal government to provide assistance.
About 10,000 people have been evacuated in Midland County, Ms Whitmer said, after days of heavy rain caused a swollen river to overflow its banks and breach the Edenville and Sanford dams.
"Experts are describing this as a 500-year event," Ms Whitmer told a news conference after a tour of the stricken areas.
She urged residents of low-lying areas to flee to higher ground.
Ms Whitmer had said earlier that parts of Midland, including downtown, could be under 2.7 metres of water by Wednesday night.
The Weather Service reported the Tittabawassee crested at midday at about 10.6m - around a metre lower than had been expected.
FEMA AND MILITARY
A spokeswoman for the Federal Energy Regulatory Commission said that as soon as it is safe, engineers will be sent to both dams to assist state and other authorities in an investigation into the cause of the breaches.
Video posted on social media showed high water lapping around buildings in downtown Midland, partly submerging bridges and roads.
Dow Chemical, which is headquartered in Midland, said in a statement it was implementing its flood-preparedness plan.
All operating units, except for facilities needed for managing chemical containment, have been shut down, the company said in a statement, adding essential staff was on the scene to monitor and manage the situation.
President Donald Trump, already scheduled to tour a Ford Motors Co auto plant in Michigan on Thursday, said on Twitter he had dispatched teams from the Federal Emergency Management Agency (FEMA) and the US military to the flood-stricken area to lend support.
Mr Trump, who had encouraged protesters demanding that Ms Whitmer ease coronavirus stay-at-home orders, tweeting a "LIBERATE MICHIGAN" message weeks ago, chided her again on Wednesday, tweeting, "Governor must now 'set you free' to help. Will be with you soon!"
The emergency unfolded as questions emerged about the past safety record of one of the two breached dams.
The Federal Energy Regulatory Commission in 2018 revoked the hydropower generating licence for the Edenville structure, accusing its operators of failing to address various deficiencies.
