Six (6) San Joaquin Valley Groundwater Subbasins—the Tulare Lake, Tule, Kaweah, Kern County, Delta-Mendota and Chowchilla Subbasins (See map below)—are currently revising local groundwater sustainability plans (GSPs) to avoid State Water Resources Control Board ‘state intervention’ over the remainder of 2023 into 2024.

As of this update (October 2023), the coordinated GSPs for a seventh subbasin—the Madera Subbasin—were resubmitted after an initial “incomplete” determination from the DWR, and are currently awaiting a final determination from the DWR of “adequacy” or “inadequacy.”
