New data out Wednesday show Californians used 15 percent more water this July than the same time last year, continuing a trend that began in June when state officials backed away from mandatory water conservation targets. While state officials seem unfazed by the increase, others worry it means Californians aren’t taking the drought as seriously as before. In June, the State Water Resources Control Board ended nearly a year of unprecedented mandatory water conservation across the state. In spring 2015, Governor Jerry Brown asked for a statewide cut of 25 percent.
