- Assembly Bill 1471 Water Quality, Supply, and Infrastructure Improvement Act of 2014
- Sustainable Groundwater Management Act: Sustainable Groundwater Management Act (SGMA) directed DWR to complete the following activities in support of SGMA: (1) develop regulations to revise groundwater basin boundaries; (2) adopt regulations for evaluating and implementing Groundwater Sustainability Plans (GSPs) and coordination agreements; (3) identify basins subject to critical conditions of overdraft; (4) identify water available for groundwater replenishment; and (5) publishing best management practices for the sustainable management of groundwater. SGMA specified actions for critically overdrafted groundwater basins, high and medium priority basins, and low and very low priority basins. SGMA also outlined the responsibility of the State Water Resource Control Board (SWRCB) with regard to groundwater basins that do not comply with SGMA.
- California Statewide Groundwater Elevation Monitoring (CASGEM): In 2009 the California State Legislature amended the Water Code with SBx7-6. SBx7-6 mandates a statewide groundwater elevation monitoring program to track seasonal and long-term trends in groundwater elevations in California's groundwater basins. The amendment required collaboration between local monitoring entities and Department of Water Resources (DWR) to collect groundwater elevation data as an important fundamental step toward improving management of California's groundwater resources.
- Groundwater Management Plans: In 1992, the Groundwater Management Act was passed to encourage local agencies to work cooperatively to manage groundwater resources. The Groundwater Management Act provided guidance on preparation of groundwater management plans (GWMPs) as a methodology for managing groundwater. AB 359 amended the act, requiring agencies to submit GWMPs to DWR and requiring DWR to provide public access to the GWMPs.
