It's being called the country's worst drought in 50 years, covering more area even than the famous 1936 drought.
In addition to farming and shipping, the lack of water is taking a huge toll on tourism and recreation.

Vermillion River Rafting owners Bob and Ruth Herbst in Oglesby, Illinois had their shortest season in 17 years of operation. They ran this summer's trips on the Vermillion River for only two-and-a-half weeks, and lost nearly $100,000 in lost business.
