Minneapolis locks closing for end of Upper Mississippi River navigation season

Published Nov. 15, 2017

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, is closing its Minneapolis locks on Sunday, Nov. 19.

Affected are the Lower St. Anthony Falls lock and Lock and Dam 1, which will be closed to commercial and recreational vessels. The Upper St. Anthony Falls lock remains closed.

The remaining locks in the district remain open until at least Dec. 10. This closure date is subject to change pending environmental factors – such as the formation of ice – that could dictate an earlier closure for the season.

The nearly 600 U.S. Army Corps of Engineers, St. Paul District, employees working at more than 40 sites in five upper-Midwest states serve the American public in the areas of environmental enhancement, navigation, flood damage reduction, water and wetlands regulation, recreation sites and disaster response. Through the St. Paul District Fiscal Year 2015 $100 million budget, nearly 1,600 non-Corps jobs were added to the regional economy as well as $155 million to the national economy.
