Mississippi River locks now open to all navigation traffic

The locks on the Mississippi River through the Twin Cities have been opened to all navigation traffic.

U.S. Army Corps of Engineers Twin Cities spokesman Mark Davidson said the water flow in the river has fallen from a peak of more than 40,000 cubic feet per second (CFS) earlier in April to just under 30,000.

"Once the CFS level dipped below 40,000 on April 20, we reopened the locks and dams here to commercial traffic," Davidson said. "Then finally today we reopened them to recreational traffic because they went below 30,000 CFS."

The U.S. Army Corps of Engineers, St. Paul District, operates the Upper St. Anthony Falls and Lower St. Anthony Falls lock and dams in downtown Minneapolis, and Lock and Dam 1 next to Minnehaha Park in Minneapolis.
