ST. PAUL, Minn. –The U.S. Army Corps of Engineers, St. Paul District, is urging all navigation enthusiasts within the Upper Mississippi River to prepare for the upcoming navigation closure.

Corps officials are asking to have all navigation vessels move south of Lock and Dam 6, near Trempealeau, Wisconsin, no later than midnight Dec. 1. This will require vessels near St. Paul, Minnesota, to depart no later than Nov. 30.

Corps engineers are preparing for several winter repairs at numerous locks within the St. Paul District. Engineers will begin repairs at Lock and Dam 6, Dec. 2. The locks include Lock and Dam 4, near Alma, Wisconsin; Lock and Dam 5, near Minnesota City, Minnesota; Lock and Dam 5A, near Fountain City, Wisconsin; and Lock and Dam 9, near Lynxville, Wisconsin, are scheduled for repairs beginning Dec. 10.

If navigation is critical through one of the locks after its closure, please contact the Corps’ Mississippi River Project Office at 651-290-5986.

The Corps’ Minneapolis locks – Lower St. Anthony Falls Lock and Dam and Lock and Dam 1 – will close for navigation Nov. 18. The Lock and Dam 1 Visitors’ Center is also closed for the season.
