On July 8, citing the state’s severe drought conditions and falling reservoir levels, Gov. Gavin Newsom signed an executive order asking urban residents in California to reduce water use by 15%.

On Tuesday, the first results were released. Statewide, urban residents missed the mark by a long shot, cutting water use 1.8% in July compared with July 2020. There were major differences across the state, with cities and water districts in North Coast areas like Sonoma and Mendocino counties — where drought conditions are worst — saving the most, and residents in many Southern California cities saving very little or even increasing use compared to the prior year.
