The U.S. Army Corps of Engineers, St. Paul District, is preparing to dredge in two separate areas within the Mississippi River to reopen the 9-foot navigation channel to commercial navigation.
The Corps and its contractors will begin dredging Friday, near Winona, in Pool 6 from river mile 718 to 724.
The Corps is already dredging in Pool 4, near Alma, Wis., at river mile 754. High flows from the June floods caused dredge material to fill areas within the channel. The Corps needs to remove the material to reestablish the required 9-foot river depth needed for navigation.
The Corps hopes to have the area near Alma reopened Friday evening and anticipates opening the area near Winona on Tuesday, July 29th with a 100-foot wide pilot channel. The Corps hopes to widen the channel to 200 feet by August 2nd.
