Californians used more water this April than they did in April 2016, according to state data, and that jump in water use came thanks to residents of Southern California. The numbers were released Tuesday by the State Water Resources Control Board, which requires urban water districts across the state to report on local water use. Gov. Jerry Brown declared an end to the state’ drought emergency in April, following a wet winter across California. That included lifting the mandatory water conservation limits imposed by the state.
