HASTINGS, Minn. – The Motor Vessel Michael Poindexter, an American Commercial Lines vessel, locks through the U.S. Army Corps of Engineers, St. Paul District’s Lock and Dam 2, near Hastings, April 11. The vessel broke through the ice in Lake Pepin, just north of Wabasha, Minnesota, April 10, en route to St. Paul, Minnesota. With the arrival of the M/V Poindexter, all of the St. Paul District locks south of St. Paul are now operational.

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.
