Drought sends Mississippi into 'uncharted territory'

A year after near-historic flooding, the river’s water levels are at near-historic lows from Cairo, Ill., where the Ohio River empties into it, to New Orleans, just north of its endpoint at the Gulf of Mexico.

About $180 billion worth of goods move up and down the river on barges, 500 million tons of the basic ingredients for much of the U.S. economy, according to the American Waterways Operators, a trade group. It carries 60 percent of the nation’s grain, 22 percent of the oil and gas and 20 percent of the coal, according to American Waterways Operators. It would take 60 trailer trucks to carry the cargo in just one barge, 144 18-wheeler tankers to carry the oil and gas in one petroleum barge.
The low water levels mean that barge companies have to lighten their load by about 25 percent so the barges ride higher in the water, reducing what’s known as the barges’ “draught.”
