High flows close locks and dams to all Mississippi boat traffic

Just days after closing three locks and dams to recreational boaters due to high flows, the U.S. Army Corps of Engineers shut down all boat traffic through metro locks and dams because the water levels are still rising.

On Monday morning, the both Upper and Lower St. Anthony Falls lock and dams -- along with the Lock and Dam 1 near Minnehaha Park -- were closed to recreational boaters. Now, those waterways are closed to commercial traffic too.

Officials say the flows passed 40,000 cubic feet per second at about 8 p.m. on Tuesday, and the Mississippi Valley Division regulation manual requires the locks and dams be closed due to unsafe navigation conditions.

This is only the third time in the past decade the locks and dams have closed to commercial traffic.

Based on weather forecasts, officials say it may take until June 8 to reopen the locks to commercial traffic. Recreational boaters won't be able to use the locks until the flows fall below 30,000 cfs.

Heavy rains last week contributed to a rapid rise in water levels, and some mild flooding has also closed the following trails in St. Paul.

  • Crosby Farm Park Trail: Paths are flooded except for the main path from Crosby Park to Elway.
  • Hidden Falls South Gate: Park is closed because water is over the road and above the curb.
  • Hidden Falls North Gate: The path behind the shelter toward wood bridge has been closed.
  • Meeker Island: The river has reached the walk bridge.
