Hope remains strong for replenishing California’s 10 largest reservoirs this spring.
Locally, Folsom Lake begins the New Year 140 percent of average. Lake Oroville, which was forced to shut off it hydropower in 2022 after , now is reported at 69 percent of average, according to the California Department of Water Resources.
