California's Groundwater (Bulletin 118)

California’s Groundwater (Bulletin 118) is the State’s official publication on the occurrence and nature of groundwater in California. The latest version of the report, California's Groundwater - Update 2020 was publicly released on November 16, 2021. The publication defines the boundaries and describes the hydrologic characteristics of California’s groundwater basins. California’s Groundwater also provides information on groundwater management and recommendations for the future.

With the passage of the Sustainable Groundwater Management Act in 2014, California’s Groundwater now serves an additional role by providing Groundwater Sustainability Agencies with three critical pieces of information regarding groundwater basins: Critical Conditions of Overdraft, Basin Boundaries, and Basin Priority. Updates to California’s Groundwater will be released every five years starting in 2020.
