The Amended Kern County Subbasin Groundwater Sustainability Plan (GSP) has been prepared by 20 GSAs and one coordinated groundwater management area. Each GSA applied for and was granted exclusive GSA status for a portion of the Subbasin under CWC §10723(c) and §10723.8. All GSAs use the Kern County Subbasin GSP (sometimes referred to as 2024 Plan) elements as its foundational Plan; however, six GSAs provide supplemental information that is inserted as blue pages throughout their GSP. The crosswalk table summarizes the contents of each GSP.

Kern Subbasin GSP plus supplemental blue pages to emphasize the complexity of the basin setting across the GSA boundary, a description of water supplies, and its history of sustainable groundwater management.
Kern Subbasin GSP plus supplemental blue pages to demonstrate that the GSA has been operating sustainably since the implementation of SGMA and discusses future practices planned to maintain its sustainability.
Kern Subbasin GSP plus supplemental blue pages to provide information of its jurisdictional boundary, groundwater levels and pumping from the Santa Margarita Formation – the primary aquifer supplying its groundwater, and details on management action KTWD-8 which modifies the districts pricing structure.
Kern Subbasin GSP plus supplemental blue pages to demonstrate how the GSA possesses several distinct characteristics that make it unique, how it is achieving the sustainability goal, and is undergoing sustainable management.
Kern Subbasin GSP plus supplemental blue pages to highlight actions taken by the GSA to implement demand management activities that will ensure it reaches sustainability at or before 2040 and provides additional information on its groundwater banking project operations, as well as its use of remote sensing to estimate evapotranspiration as a significant tool for managing demand
Kern Subbasin GSP plus supplemental blue pages pertaining to conditions and characteristics unique to the GSA that demonstrate it will achieve sustainability. Additional information highlights the unique hydrogeologic conditions including naturally degraded groundwater quality; details of local studies related to the cause, rate, and extent of subsidence; and information on projects and management actions that maintain sustainable groundwater management within its GSA boundary.
