Low Mississippi River water levels are increasing transportation costs for American farmers as drought disrupts barge traffic. Barge operators have cut cargo loads to prevent vessels from running aground.
Freight from St. Louis rose roughly 77% above the three-year average during recent low-water periods.
Higher barge freight widens the gap between interior and Gulf prices, pressuring farm-gate values for corn and soybeans. Reduced loads also cut effective barge capacity on the main export corridor.
