ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, closed its three Twin Cities locks yesterday, once again, to recreational boats due to increasing high water flows in the Mississippi River.
The Upper St. Anthony Falls and Lower St. Anthony Falls locks in downtown Minneapolis and Lock and
Dam 1, located next to Minnehaha Park in Minneapolis, were closed to recreational boaters, when flows passed 30,000 cubic feet per second, or cfs. Based on National Weather Service forecasts, flows will be more than 30,000 cfs for the next week.
According to the Corps' Mississippi Valley Division lock and dam regulation manual, the district is required to close the lock and dams to recreational traffic at 30,000 cfs because the high flows are unsafe. Commercial traffic at these locks is shut down at 40,000 cfs.
These locks were previously closed for high flows from April 11-21.
The nearly 700 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 Corps’ Fiscal Year 2011 $175 million budget, nearly 2,800 non-Corps jobs were added to the regional economy as well as $271 million to the national economy.
