State officials say Californians made significant progress saving water in December. The State Water Resources Control Board in Sacramento on Wednesday reported the most recent conservation figures. They say residents and businesses statewide use roughly 20 percent less water in December. That’s compared to the same time in 2013, the year before Gov. Jerry Brown declared a drought emergency. They say that since mandatory conservation started in June 2015, Californians have saved enough water enough water to serve nearly one-third of the state’s population for a year. California had endured more than five years of drought until recent rain and snow doused the state. State regulators will decide Wednesday whether to keep drought regulations that require monthly conservation reports.
