Following the adoption of a Groundwater Sustainability Plan (GSP) the Sustainable Groundwater Management Act (SGMA) requires GSAs to submit annual reports to the CA Department of Water Resources on April 1 of every year. The Annual Report serves to inform and update both the State and stakeholders in the Tulare Lake Subbasin on groundwater conditions and sustainability progress.

The Annual Report includes both data and a description of the GSAs’ progress toward implementation of their GSPs. Data includes information from the Kings Subbasin’s seven GSAs’ monitoring networks, groundwater extractions, surface water supply, total water use, and changes in groundwater storage.
