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 in the Kings Subbasin (DWR Bulletin 118). Through its various surface water resources and several decades of proactive groundwater recharge activities, this portion of the Kings Subbasin has not experienced significant overdraft conditions experienced elsewhere in the subbasin. Drought and other challenges, however, have contributed to a gradual decline in overall groundwater conditions that will be addressed through the implementation of the Groundwater Sustainability Plan for the North Kings region.


The North Kings GSA, consistent with the Sustainable Groundwater Management Act (SGMA) of 2014, has developed a Groundwater Sustainability Plan (GSP) 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 (the GSP was revised in 2022 following DWR’s review). 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 Department of Water Resources to evaluate those plans and coordination agreements.

Groundwater Sustainability Plan

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.

The GSP was revised and resubmitted in 2022 following DWR’s 2-year review and determination. The revised GSP was recommended for approval in March 2023.

Groundwater Sustainability Plan Comments

Department of Water Resources Review – 2022

The Department of Water Resources (DWR) provided comments in January 2022 on the North Kings GSA’s Groundwater Sustainability Plan (GSP) following a 2-year review period. As with many of the GSPs across the State and all in the San Joaquin Valley, the North Kings GSA’s GSP was determined to be incomplete, requiring revisions within 180 days.

DWR’s comments were addressed to the Kings Subbasin’s seven GSAs and identified deficiencies on the thresholds set for groundwater levels, land subsidence, water quality and interconnected streams. A coordinated effort among the seven Kings Subbasin GSAs, including the North Kings GSA, resulted in a revised GSP that adequately addressed their concerns. The revised GSP was recommended by DWR staff for approval in March 2023.
