California’s Groundwater Update 2020 California’s Groundwater (Bulletin 118) is an inventory and assessment of available information on the occurrence and nature of California’s groundwater to inform decisions affecting the protection, use, and management of the resource. The California Department of Water Resources (DWR) publishes California’s Groundwater to meet requirements of the California Water Code (Section 12924).
The requirements include establishing basin boundaries and priority levels, as well as determining which basins are subject to critical conditions of overdraft. DWR must also document groundwater use, management, monitoring, and conditions found throughout California. With the passage of the Sustainable Groundwater Management Act (SGMA) in 2014, the report now serves an additional role by providing Groundwater Sustainability Agencies (GSAs) with important groundwater related data, including remote sensed land use and subsidence, climate data, and modeling.
California’s Groundwater — Update 2020 includes information on:
- Location, status, and characteristics of California’s groundwater basins
- Water markets, water transfers, managed aquifer recharge, and impacts of a changing climate
- Groundwater demands, supplies, and development • Groundwater use and management
- Groundwater monitoring activities
- Groundwater conditions
