Welcome to the Department of Water and Natural Resources for Madera County.

Our department develops and implements county policy and activities regarding surface water, groundwater and watershed management. We work with a variety of committees, organizations and stakeholders regarding water and natural resource issues.

Currently much of our time involves preparing for compliance with the Sustainable Groundwater Management Act (SGMA) passed by the Legislature and signed by Governor Jerry Brown in 2014. This piece of legislation fundamentally changes management of California’s groundwater basins. SGMA mandates the formation of Groundwater Sustainability Agencies (GSAs) and requires the adoption of Groundwater Sustainability Plans (GSPs) for basins or subbasins designated as medium or high-priority by the CA Department of Water Resources. GSPs are mandatory to eliminate overdraft conditions in aquifers and to return them to conditions that assure long-term sustainability within 20 years of implementation.

SGMA Facts

Subbasins  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.

GSPs  Each of the subbasins above 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.
