Seven GSAs have been established within the Basin, each acting as the exclusive GSA in their respective areas. The seven GSAs form the Cosumnes Subbasin SGMA Working Group (Working Group): Amador County Groundwater Management Authority (ACGMA), City of Galt, Clay Water District, Galt Irrigation District (GID), Omochumne-Hartnell Water District (OHWD), Sacramento County, and Sloughhouse Resource Conservation District (SRCD). The Working Group developed this single coordinated GSP to meet SGMA regulatory requirements, reflect stakeholder values, and preserve local control over management of the groundwater resource.

Groundwater Sustainability Plan for the San Joaquin River Exchange Contractors GSP Group in the Delta-Mendota Subbasin (5-022.07)

San Joaquin River Exchange Contractors Water Authority (SJRECWA) | June 30th, 2022

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

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. Due to size, this file has been divided. Part 1, Part 2, Part 3, Part 4, Part 5, Part 6, Part 7, Part 8

Groundwater Update 2013: San Joaquin River Hydrologic Region Report

California Department of Water Resources (DWR) | April 1st, 2016

The primary goal of the San Joaquin River Hydrologic Region (San Joaquin River region) groundwater update is to expand information about region-specific groundwater conditions for California Water Plan Update 2013, and to guide more informed groundwater management actions and policies. A second goal is to steadily improve the quality of groundwater information in future California Water Plan updates to a level that will enable regional water management groups (RWMGs) to accurately evaluate their groundwater resources and implement management strategies that can meet local and regional water resource objectives within the context of broader statewide objectives. The final goal is to identify data gaps and groundwater management challenges meant to serve as a guidepost for prioritizing future data collection and funding opportunities relevant to the region. This regional groundwater update is not intended to provide a comprehensive and detailed examination of local groundwater conditions, or be a substitute for local studies and analysis. However, where information is readily available, the update does report some aspects of the regional groundwater conditions in greater detail.
