The drought this summer, affecting most of the U.S., which is heavily influenced by one of the deepest main waterway in the country — the Mississippi River (2530 km). The river has a critically low level of water, which greatly affects the shipping number of states from Minnesota to the Gulf of Mexico.
And the situation did not improve even after heavy rains and Hurricane Isaac, which occurred a few days ago. Experts estimate the state of Mississippi as one of the worst in recent decades. Interestingly, in the last year, it was quite the opposite, since then a series of rains caused flooding, and coastal areas were flooded waters of the Mississippi, which was almost three times as wide.
The current width of the river is 450-600 meters. In the Memphis water level by more than 3.5 feet below normal. Shipping companies have been forced to load their barges fewer goods and commissioning more barges that during the voyage they ran aground. After all, every additional reduction of the water level in the river by 2.5 cm reduces capacity barges by 17 tons. The more flights are barges, the more expensive in the end is that the products they carry. Basically, it's grain, fertilizers and fuel.
Last level of the Mississippi sunk so low in 1988. Then the loss of barge freight amounted to $ 1 billion loss in 2012 will be not much less.
