ABOUT US

The White Wolf Subbasin GSA is formed by three water districts; Arvin-Edison Water Storage District (AEWSD), Tejon-Castac Water District (TCWD), and Wheeler Ridge Maricopa Water Storage District (WRMWSD), as well as the Kern County.

The first comprehensive groundwater legislation in California history, the Sustainable Groundwater Management Act of 2014 (SGMA), was enacted on 16 September 2014 as part of a three-bill package including Assembly Bill (AB) 1739 (Dickinson), Senate Bill (SB) 1169 (Pavley), and SB 1319 (Pavley). The legislation provides a framework for the sustainable management of groundwater by local agencies, with an emphasis on the preservation of local control. The state agencies primarily responsible for implementing SGMA are the California Department of Water Resources (DWR) and the State Water Resources Control Board (SWRCB).

Implementation of SGMA will be phased in over several years, and the first major milestone was achieved in October 2014 with the adoption of the Basin Boundary Emergency Regulations. As directed by California Water Code (CWC) §10722.2, DWR developed these regulations to provide local agencies the opportunity to petition DWR to consider a change to existing groundwater basin boundaries. The regulations allow basin boundary modification requests to be submitted on both jurisdictional and scientific grounds. The first basin boundary modification requests were accepted by DWR between 1 January and 31 March 2016, and at certain intervals therafter coincident with the update of Bulletin 118 – California’s Groundwater.

In March 2016, TCWD, WRMWSD, and AEWSD submitted a request (“Request”) to the California Department of Water Resources (“DWR”) to subdivide the Kern County Subbasin of the San Joaquin Valley Groundwater Basin (DWR 5-22.14) into two separate subbasins: the Kern County Subbasin and the White Wolf Subbasin. The Request, which relied upon scientific evidence demonstrating that the White Wolf Fault provided a significant impediment to groundwater flow, was recommended by DWR for approval on 1 July 2016. Three public hearings were held in July 2016 to present the Draft Approved Basin Boundary Modifications. On October 18, 2016 the final Basin Boundary Modification was published and the White Wolf Subbasin was created.

The Sustainable Groundwater Management Act (SGMA) establishes separate requirements and deadlines for groundwater basins that have been determined by DWR to be in a condition of critical overdraft. In order to facilitate SGMA implementation following the basin boundary modifications, DWR reevaluated the newly redefined basins to asses if they were subject to conditions of critical overdraft.  Anticipating he final list of critically-overdrafted basins to be published in Bulletin 118 – Interim Update, late Fall of 2016, the three districts (AEWSD, TCWD, WRMWSD) and the county (Kern) submitted a letter to DWR providing data and information intended to assist DWR in its review of the groundwater conditions in the Subbasin. The information provided supported the determination that the Subbasin was not subject to conditions of critical overdraft.  On December 23, 2016 DWR published their updated Bulletin 118 and the White Wolf Subbasin was no longer designated as critically-overdarfted.

On May 30, 2017 the application for the formation of the White Wolf Subbasin Groundwater Sustainability Agency was submitted.  That same day it was approved by DWR and posted on their website.

STAKEHOLDER WORKSHOP #1

The White Wolf GSA hosted a public workshop to discuss the SGMA and its implementation in the White Wolf Subbasin on June 4th, 2019.

This workshop included a technical presentation on the current status of basin characterization including the Hydrogeological Conceptual Model (HCM), the definition of current groundwater conditions, and a water budget for historical (1995-2014) and current (2015) conditions. A copy of the technical presentation can be downloaded here (click link to download).
