Gov. Gavin Newsom on Thursday will be in the Bay Area to announce a new water supply strategy for California as the state contends with a historic drought. Newsom is scheduled to be in Contra Costa County for a news conference detailing “water supply actions” California is taking to adapt to hotter, drier conditions caused by climate change, the governor’s office said. He also is expected to announce new leadership for California’s infrastructure efforts. Drought has been a major concern for Californians. A new study by the nonpartisan Public Policy Institute of California found that 68% of state residents say the water supply is a big problem where they live.
