The U.S. Army Corps of Engineers, St. Paul District, will reopen several locks and dams in
March that were closed for winter maintenance:
Lock and Dam 2 in Hastings, Minnesota – which was dewatered for inspection and concrete repairs –
will reopen to navigation March 6.
Lock and Dam 4 in Alma, Wisconsin – which had been closed for maintenance on its lower guidewall
end cell, including placement of sheet pile and concrete – will also reopen March 6.
Lock and Dam 3, near Welch, Minnesota; and Lock and Dam 7, near La Crescent, Minnesota – both
closed for guidewall maintenance – will reopen to navigation March 16.
The St. Paul District navigation program provides a safe, reliable, cost-effective and environmentally
sustainable waterborne transportation system on the Upper Mississippi River for the movement of commercial
goods and for national security needs. To do this, the district maintains a 9-foot navigation channel and 13
locks and dams from Minneapolis to Guttenberg, Iowa. Keeping this system open is vital to the nation’s
economy.
