Department of the Army, U.S. Army Corps of Engineers, DOD.




The three Mississippi River locks in Minneapolis, MN (Upper St. Anthony Falls, Lower St. Anthony Falls, and Lock and Dam 1) currently operate 19 hours per day/7 days per week during the navigation season. This level of service follows the guidance from the Corps Inland Marine Transportation System (IMTS) Board of Directors.

Section 2010 of the Water Resources Reform and Development Act of 2014 (WRRDA) directed the Secretary of the Army to close the Upper St. Anthony Falls Lock and Dam located on the Mississippi River at river mile 853.9 no later than 1 year after the enactment date of WRRDA 2014.

With the expected closing of the Upper St. Anthony Falls lock, it is anticipated the remaining two Minneapolis locks will have less than 500 commercial lockages per year. To meet IMTS guidance, it is proposed Lower St. Anthony Falls and Lock and Dam 1 transition to one 10-hour shift per day/7 days per week during the 2015 navigation season and beyond. The navigation season on the Upper Mississippi normally begins in March, depending on river conditions, and wraps up by the end of November. Pool levels will not be affected by change of operating hours.
