California’s success in slashing water use in July by 31 percent — smashing the goal set by Gov. Jerry Brown — shows residents have come to terms with what four dry years have done to the state’s water supply.

 The dramatic savings, reflected in state data on urban water use released Thursday, marks the second straight month in which Californians met or exceeded the 25 percent statewide target, dodging potential fines for water districts that fall short.

Brown lawns are the norm in many places and unwashed cars the expectation as the state’s big rivers and reservoirs have shriveled amid the drought.
