An effort by California officials to carry their success with water conservation beyond the drought is not sitting well with local water managers, many of whom are eager to shake off state control. Gov. Jerry Brown declared the state’s five-year drought officially over in April, following an unusually wet winter that refilled reservoirs and buried the Sierra Nevada in deep snow. But Brown also made it clear, given the likelihood of future droughts, that he wasn’t going to ease up on water conservation.
