The Mississippi River is one of our main sources for transporting goods. More than 500 tons of grain, coal and other goods are moved every year.
All along the lower Mississippi — from Memphis, Tenn., to New Orleans — water levels are at record lows. Sandbars have appeared in midstream, and broad beaches now spread out at the edges of what were green riverbanks. Traffic has slowed to a crawl and, on some stretches of the river, has been at a standstill since June as water levels have dropped so low that even barges requiring just 9 feet of water are running aground.

If the Mississippi river is closed, alternative transportation will be needed and the costs of moving food and other products will be passed on to consumers.
