Big Valley Groundwater Sustainability Agency

About the Agency



In 2014, California passed the Sustainable Groundwater Management Act (SGMA) (AB1739, SB 1168, SB 1319), authorizing local groundwater sustainability agencies (GSAs) to develop groundwater sustainability plans (GSPs) for a subset of California’s alluvial aquifers. To comply with SGMA, GSAs must achieve sustainable groundwater management, defined by SGMA as the avoidance of locally-defined undesirable results. To achieve sustainability, GSAs must develop and implement effective groundwater management plants that consider the interests of all beneficial uses and users of groundwater, including environmental users of groundwater. [Water Code § 10723.2.]


The Big Valley Subbasin Groundwater Sustainability Agency will develop, adopt, and implement a groundwater sustainability plan for the Big Valley Subbasin in order to implement the Sustainable Groundwater Management Act’s requirements and achieve the sustainability goals outlined in SGMA.

Throughout the development and implementation of the Big Valley Subbasin GSP, the GSA will involve the public and local stakeholders through outreach and engagement efforts.
