Freed from stringent statewide drought controls, Californians have begun using more water. Urban consumption grew by 8 percent in June compared to a year earlier, according to figures released Tuesday by the State Water Resources Control Board. June was the first month in which California was operating under significantly relaxed drought regulations, and state regulators said they will monitor conservation going forward. If necessary, they said drought mandates could be reinstated. Californians still managed to reduce water use by 21.5 percent in June, compared with the 2013 baseline established by the state.
