Chemical plant
On May 19, 2020, the Edenville Dam failed, followed by the Sanford Dam downstream being overtopped and a dike breaking at Poseyville, resulting in major flooding in Midland County. 10,000 people were evacuated including a seniors home and a few hospital patients. Two emergency shelters had to be relocated due to flooding and electrical power losses. Floodwater entered the Dow Chemical plant, forcing its shutdown and mixing with its containment ponds, leading to concern over pollution. The next day, water levels were predicted to reach 38 feet: four feet higher than the flood of 1986. National Guard units and a FEMA team were brought in to assist.
