Michigan dams breached, thousands flee flooding
EDENVILLE, Michigan — Two breached dams caused by several days of rainfall and rising water on Tuesday forced the evacuation of about 10,000 people in midMichigan, where the governor said one downtown could be “under about nine feet of water” by morning.
For the second time in less than 24 hours, families living along two lakes and a river were ordered Tuesday to leave home.
The National Weather Service issued a flash flood watch for locations along the Tittabawassee River after the breach at the Edenville Dam in Midland County, about 225.31 kilometres north of Detroit and the Sanford Dam, about 11.26 kilometres downriver from Edenville.
“Extremely dangerous flash flooding is ongoing along the Tittabawassee River in Midland county due to catastrophic dam failures at the Edenville and Sanford dams,” the weather service said on its website, noting that anyone near the river should seek higher ground immediately, be prepared for immediate evacuations, and not drive into flooded roadways. “This flooding will continue all along the length of the river in Midland county, and possibly extending into Saginaw county where a Flash Flood Watch is also in effect.”
Michigan Gov. Gretchen Whitmer late Tuesday declared a state of emergency for Midland County and urged residents threatened by the flooding to evacuate the area. She said shelters have opened across the county and are available to residents who need a place to go.
“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.“
Whitmer said downtown Midland faced an especially serious flooding threat. “In the next 12 to 15 hours, downtown Midland could be under approximately nine feet of water. We are anticipating an historic high water level.”
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.
The evacuations include the towns of Edenville, Sanford and parts of the city of Midland, which has 42,000 people, according to Selina Tisdale, spokeswoman for Midland County.
“People are communicating well and looking after each other and their loved ones,” Tisdale said. “We’re heartbroken for those with lots of home and property damage.”
The evacuations in Michigan followed days of heavy rains in parts of the Midwest that also brought flooding to Chicago and other parts of Illinois, Ohio and other states.
“We were back at home and starting to feel comfortable that things were calming down,” said Catherine Sias, who lives about 1.61 kilometres from the Edenville Dam and left home Tuesday morning. “All of a sudden we heard the fire truck sirens going north toward the dam.”
Sias, 45, said emergency alerts then began coming on her cellphone and people started calling to make sure they were safe.
“While packing, there were tons of police and fire trucks going up and down the roads,” she added. “As far as I know, all of our neighbours got out.”
M-30, the state highway trunkline that’s also the main road through Edenville and the route Sias was using to evacuate, was backed up with vehicles.
While driving, she saw the rushing Tittabawassee River. “It was very dramatic, very fast and full of debris,” she said.
Edenville Dam holds back Wixom Lake. Officials also were watching the Sanford Dam south of Edenville. The city of Midland, which includes the main plant of Dow Chemical, sits on the banks of the Tittabawassee River about 12.87 kilometres away from that dam.
Dow Chemical Co. has activated its emergency operations centre and will be adjusting operations as a result of current flood stage conditions, spokeswoman Rachelle Schikorra said in an email.
“Dow Michigan Operations is working with its tenants and Midland County officials and will continue to closely monitor the water levels on the Tittabawassee River,” Schikorra said.
Earlier, Midland County 911 sent out a series of alerts saying the Edenville and Sanford dams were at risk of failing.
Midland County Emergency Management later said that the dams were “structurally sound.” It said water flowing through the dam spillgates couldn’t be controlled, however, so evacuation measures remained in place.
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.
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.
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.
