In this Aug. 3, 2012 photo, Tony Frost, of Frost Farms, lines up a hose into a 1,000-gallon water tank in Tallula, Ill., as he fills it to take back to the farm for his cattle. After months of drought, the central Illinois creeks and ponds that the 300 cows and calves drink from on the farm are dry or close to it. Frost has to buy and haul water, about 4,000 gallons a day, split up in four trips to different pastures. (AP Photo/Seth Perlman)
