The Blue Earth County Sheriff’s Office says the county’s emergency management agency became aware of debris accumulating at the Rapidan Dam, which is just over 10 miles southwest of Mankato, Sunday evening. 


Officials found water rushing around the western side of the dam. It was described Monday morning to be in “in imminent failure condition.”

Officials say it’s not yet known if the dam will fail or if it will stay in place. As of Monday afternoon no evacuation orders have been issued. 

A Facebook Post published on the City of Mankato’s Facebook page says officials are confident the city’s levee system will protect residents if the dam fails and sends high rushing water into the population center. 

The Blue Earth County Sheriff’s Office says anyone who would be in immediate danger in the event of a dam failure has been notified.
