The Department of Water Resources (DWR) has released the final version of California’s Groundwater: Bulletin 118 – Update 2025, the State’s official and most comprehensive report of groundwater monitoring, conditions, and management across California. The report builds upon the previous update in 2020 and contains critical information about the state’s groundwater supplies from 2020 to 2024, a period marked by record-setting dry and wet weather events and increasing ambient temperatures. It shows considerable progress made by California and local agencies towards reaching the goals of groundwater sustainability outlined in the Sustainable Groundwater Management Act (SGMA).
