An aerial photo made with a drone shows barges and tow boats on the Ohio River at the junction with the Mississippi River at Cairo, Illinois, USA, 20 October 2022. The Mississippi River, a main route of commercial barge traffic for grains, wheat, and coal, is historically low causing major supply chain disruptions. Barge freight rates have increased dramatically from draft levels reductions in the Mississippi River system as farmers harvest crops and need the river to get them to markets around the world.
