(AP) – Flooding on the Blue Earth River caused a 114-year-old dam to fail Monday morning. Le Sueur County residents in low-lying areas of the Minnesota River Valley were advised to evacuate.
The dam is located 10 miles southwest of Mankato.
The failure is expected to cause the Minnesota River at Mankato to crest just below major flood stage Tuesday morning. There are 21 cities in that watershed, of which Mankato and Fairmont are the largest.
