Madera County is comprised of three subbasins, designated by the CA Department of Water Resources as critically overdrafted, and “high priority”:
(1) the Chowchilla Subbasin;
(2) the Madera Subbasin; and
(3) a portion of the Delta-Mendota Subbasin.
Each of these subbasins must submit a Groundwater Sustainability Plan (GSP) by January 2020. These subbasins are required to achieve “sustainability” by the year 2040. The method by which sustainability will be achieved will be illustrated in the GSP, which will be drafted in partnership by the irrigation district, water districts, cities and Madera County. The process is meant to be a public and participatory process. Madera County will consider input from stakeholders and seeks achieve public support toward a common goal of long-term sustainability.
The Chowchilla Subbasin is comprised of the following four groundwater sustainability agencies: Chowchilla Water District, Madera County, Triangle T Water District and Merced County.
The Madera Subbasin is comprised of seven groundwater sustainability agencies: Madera County, City of Madera, Madera Irrigation District, Root Creek Water District, Madera Water District, New Stone Water District, and Gravelly Ford Water District.
Madera County encompasses a small portion of the Delta-Mendota Subbasin, including the following groundwater sustainability agencies: Aliso Water District, Madera County, and the San Joaquin River Exchange Contractors.
