In 2014, California passed the Sustainable Groundwater Management Act (SGMA) which regulates groundwater at scale for the first time, requiring the state’s largest source of stored water to be managed for long-term resilience. SGMA delegates the responsibility of achieving sustainable groundwater management by 2040 to local Groundwater Sustainability Agencies (GSAs). Balancing groundwater basins to achieve sustainability will require increasing water supply to the basin and/or decreasing water demand. This report focuses on the design and testing of the Fox Canyon groundwater market and serves as a resource for GSAs and other public agencies, organizations, practitioners and stakeholders involved in water resource management and contemplating the creation of groundwater markets to meet SGMA’s sustainability mandate.
The full report and the report summary available here on the Groundwater Resources Hub.
