California Gov. Gavin Newsom on Thursday asked state residents to voluntarily reduce household water usage by 15% due to worsening drought conditions. From a report: Newsom is yet to issue a California-wide state of emergency or mandate any water use restrictions. However, on Thursday, he expanded his regional drought state of emergency to apply to 50 of the state’s 58 counties, which includes about 42% of the population, Newsom said. Newsom encouraged residents to take shorter showers, run dishwashers only when completely full and refrain from watering lawns.
