Falling water levels on the Mississippi have exposed sandbars and led barge operators to cut drafts, with Ceres Barge Line trimming loads to 10 feet 6 inches. Shippers now need 18 barges instead of 17 for the same grain volume out of St. Louis.
St. Louis river levels are forecast to fall toward 1 foot by mid-October.
Draft restrictions raise the cost of moving grain south from St. Louis, which widens basis discounts and reduces farm-gate prices. Freight rates are likely to rise while water stays low.
