Welcome to the Northern & Central Delta-Mendota Region GSP page. 

This page is dedicated to providing information on activities, meetings and resources related to the sustainable management of the Northern and Central Delta-Mendota (N-C DM) Regions of the Delta-Mendota Subbasin

Northern & Central Delta-Mendota GSP

The Northern & Central Delta-Mendota GSP Regions are comprised of eight (8) GSAs: the Central Delta-Mendota GSA, the City of Patterson GSA, the DM-II GSA, the Northwestern Delta-Mendota GSA, the Oro Loma Water District GSA, the Patterson Irrigation District GSA, the West Stanislaus Irrigation District GSA, and Widren Water District GSA. 

These GSAs have agreed to coordinate to develop, adopt, and implement one GSP covering the Northern and Central Regions of the Delta-Mendota Subbasin. Additionally, these GSAs are coordinating the N-C DM GSP with five (5) other GSPs being developed simultaneously, and ultimately implemented, in the Delta-Mendota Subbasin for achieving groundwater sustainability basinwide. 

All interested parties, including the public, cities, and counties, are invited to participate in the planning and development of the N-C DM GSP through meetings and workshops.
