FRESNO, Calif. (AP) - Farmers in parts of California's Central Valley say that for a second year running they anticipate receiving no irrigation water from a federally operated system of canals and reservoirs. The U.S. Bureau of Reclamation is expected to announce Friday how much water it will release for farming. This comes as California enters its fourth drought year. Westlands Water District spokeswoman Gayle Holeman says last year farmers in the district left thousands of acres unplanted or irrigated by pumping scarce ground water. She says this year they'll have to make the same tough choices. Doug Carlson of California's Department of Water Resources says that the state anticipates providing 15 percent of what it normally supplies to farms and communities, a figure that may change. He says the snowpack today is at 19 percent of historical average.
