California is in the third year of its worst drought in decades. But you wouldn't know it by looking at how much water the state's residents and businesses are using. According to a recent state survey, Californians cut the amount of water they used in the first five months of the year by just 5 percent, far short of the 20 percent reduction Gov. Jerry Brown called for in January. In some parts of the state, like the San Diego area, water use has actually increased from 2013.
