Low water level on Mississippi River hurts US grain shipping
A lack of rainfall in the central United States has brought the mighty Mississippi River to its lowest depth in years, causing headaches for shippers and squeezing farmers who rely on the busy waterway to take their product to the Gulf of Mexico.. US Department of Agriculture (USDA) figures show that about two-thirds of US sea-based grain exports last year departed from the Gulf of Mexico, most often after being shipped by barge down the Mississippi River.
