For the week ending July 21, grain barge shipments on the locking portions of the Mississippi, Ohio, and Arkansas rivers experienced a second week of decreased barge tonnages. For several weeks, high water on the Upper Mississippi River has slowed barge traffic from St. Paul, MN, to Davenport, IA. Delays are also occurring at Melvin Price Locks and Dam, on the Mississippi River, due to repair work that has closed the main, 1,200-foot lock chamber. Barges can transit the smaller, 600 ft.
