Groundwater Sustainability Plan (GSP)
Groundwater Sustainability Plan
Groundwater Sustainability Plan (GSP) – A plan developed by a GSA to achieve sustainability pursuant to the SGMA.
The San Joaquin River Exchange Contractors GSA (SJREC GSA) worked with 10 neighboring GSA’s to develop a joint GSP. The main body of the GSP was developed for the SJREC GSA with a discrete chapter for each partner GSA in the plan.
The GSP was adopted by the SJREC GSA on December 13, 2019.
The GSP has been amended in response to the January 21, 2022 DWR Determination letter to Delta-Mendota Subbasin’s Point of Contact that included evaluation of the San Joaquin River GSA’s Groundwater Sustainability Plan (GSP). The amended plan was adopted by the SJRECGSA Board on July 5, 2022.
On March 2nd, 2023, the Department of Water Resources announced decisions for Groundwater Sustainability Plans (GSPs), finding that numerous subbasins were found to be inadequate. One of these subbasins—the Delta-Mendota Subbasin in San Joaquin, Stanislaus, Merced, Fresno, Madera, and San Benito counties—includes a region for which the Exchange Contractors are responsible for developing the GSP. Our GSP for our region was one of six plans for the larger Subbasin of which we are a part. See attached FAQs sheet for additional information.
The California Department of Water Resources (DWR) has developed some useful tools to aid in GSP development. See below for some links to the DWR tools.
