The Kings Subbasin is located in the southern part of the San Joaquin Valley with the majority of surface water being supplied from the Kings and San Joaquin Rivers. The North Kings Groundwater Sustainability Agency (NKGSA) is one of seven GSAs within the Kings Groundwater Subbasin (DWR Bulletin 118: 5-022.8). Through its various surface water resources and several decades of proactive groundwater recharge activities, this portion of the Kings Basin have not experienced significant overdraft conditions experienced elsewhere in the basin. Drought and other challenges, however, have contributed to a gradual decline in overall groundwater conditions that will be addressed through development of a sustainability plan for the North Kings region.


The North Kings GSA, consistent with the Sustainable Groundwater Management Act of 2014, has developed a Groundwater Sustainability Plan ahead of the legislated deadline of January 31, 2020. This document was developed in compliance with the California Department of Water Resources’ Groundwater Sustainability Plan Emergency Regulations. Developed pursuant to Water Code Section 10733.2, the regulations describe the components of groundwater sustainability plans, intra-basin coordination agreements, and the methods and criteria to be used by DWR to evaluate those plans and coordination agreements.

Groundwater Sustainability Plan Submitted to DWR

The North Kings GSA finalized the Groundwater Sustainability Plan (GSP) and submitted it to the California Department of Water Resources (DWR) on January 28, 2020, ahead of the January 31, 2020 mandate.

DWR Portal

The NKGSA’s GSP has been posted on the DWR SGMA portal and a 75 day public comment period commenced on January 31, 2020, and will end on April 15, 2020. The DWR has 2 years to complete its review of the NKGSA GSP and make a determination about its adequacy.

Groundwater Sustainability Plan Comments Received

NKGSA received comments on its draft Groundwater Sustainability Plan (GSP).  All comments are provided here on NKGSA’s website to provide transparency to any interested person or organization about the GSP and comments offered by stakeholders.  NKGSA gives due consideration to all comments and will continue to consider comments as NKGSA implements the GSP.  NKGSA understands that new or different data will develop, and new or different comments might arise.  Accordingly, NKGSA recognizes that modifications to its GSP implementation policies or efforts might be appropriate in the future.  NKGSA looks forward to working with stakeholders to implement SGMA.

Inter/Intra-basin Coordination

Coordination Agreement

Consistent with the DWR Groundwater Sustainability Plan Emergency Regulations, an intra-basin coordination agreement is required to be submitted in subbasins where two or more Groundwater Sustainability Plans are developed. In addition to the North Kings GSA, six additional Groundwater Sustainability Plans were finalized and submitted to DWR on January 28, 2020, along with a fully executed Coordination Agreement.

Annual Report

The Sustainable Groundwater Management Act (SGMA) requires GSAs to submit annual reports to the California Department of Water Resources (DWR) on April 1 following adoption of a Groundwater Sustainability Plan (GSP). The Annual Report serves to inform and update both the State and stakeholders in the Kings Subbasin on groundwater conditions and GSP implementation over the prior year.

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 GSA’s monitoring networks, groundwater extractions, surface water supply, total water use, and changes in groundwater storage.

Annual Report 2020

The North Kings GSA together with the six other GSAs in the Kings Subbasin submitted the first Annual Report on April 1, 2020 for water year 2019 (Oct ’18 – Sep ’19).
