The series of Army Corps dams. Sanding-bagging under way at Minnesota City.

Dams 3 and 4 already shut: Will 5 be next?

MINNESOTA CITY, Minn. – The question looming for Army Corps workers at the Minnesota City dam whether they’ll be the next to grind their  lock shut. The rising Mississippi River already has forced the Corps to shut down locks at the Alma and Red Wing dams. Lock and Dam 5 Lockmaster Judy Denzer, at Minnesota City, told a KTTC interviewer: “We actually started sandbagging. If it gets to higher levels, then we will get a whole crew in here just to put everything out.”
