Sustainable Groundwater Management Act (SGMA)

Groundwater Management under SGMA

The Sustainable Groundwater Management Act (SGMA) is an unfunded State law requiring groundwater subbasins be sustainable by 2040. SGMA’s intent is to allow local agencies to sustainably manage groundwater. Over 260 local Groundwater Sustainability Agencies (GSAs) formed in California to implement the law. Located in the Kings Subbasin, the McMullin Area GSA, or “MAGSA”, will develop projects and management tools in the coming years that bring the best possible outcome for the landowners and communities served by the agency.

What is “sustainability”?Sustainability means balanced levels of

groundwater by 2040. SGMA defines sustainable groundwater management as the management and use of groundwater in a manner that does not cause undesirable results for the following indicators:

Sustainable Groundwater Management Act (SGMA)

Mandates groundwater sustainability by the year 2040

Grants local control to Groundwater Sustainability Agencies or “GSAs”

Requires GSAs develop and submit a Groundwater Sustainability Plan to the CA Department of Water Resources by January 2020

California law signed in September 2014

Chronic Lowering Groundwater Levels

Reduction of Storage

Seawater Intrusion

Degraded Water Quality

Land Subsidence

Surface Water Depletion

Kings Subbasin

Kings Subbasin CoordinationSGMA requires that an entire subbasin be sustainable.

In subbasins where GSAs develop multiple GSPs, like the Kings Subbasin, a single Coordination Agreement must be submitted to the State with information necessary to show how multiple GSPs can achieve the sustainability goals for the entire subbasin. The seven Kings Subbasin GSAs will finalize an agreement on how to coordinate their individual GSPs. Coordination includes elements like utilizing the same data and methodologies.

MAGSA’s GSP StatusThe McMullin Area Groundwater Sustainability

Agency (MAGSA) was formed to locally implement SGMA in a portion of the Kings Subbasin. MAGSA is one of seven GSAs within the Kings Subbasin who developed its own GSP. The 7 Kings Subbasin GSAs will submit their GSPs to the CA Department of Water Resources by January 30, 2020. MAGSA concluded a public review of its draft GSP at its October 16, 2019 Public Hearing.

Groundwater Sustainability Plan (GSP)

What is a Groundwater Sustainability Plan (GSP)?

GSAs are respsonsible for developing a GSP. A GSP is a roadmap for how a subbasin will avoid the adverse effects of overdraft and achieve balanced levels of groundwater to reach sustainability. The GSP includes a physical description of the groundwater management area including groundwater conditions, a water budget, management criteria, a monitoring program, and projects and management actions to help the GSA reach measurable objectives by 2040.

What the MAGSA GSP does

Documents historical and current groundwater conditions

Defines a path forward for groundwater sustainability

What the MAGSA GSP could doProvide opportunity for landowners to market groundwater based upon allocation per acre system

Incentivize growers to flex land use, including crop conversion or fallowing

What the MAGSA GSP does NOT do

Does NOT require immediate pumping restrictions

Does NOT require immediate changes to crops

Does NOT require immediate land use changes

Does NOT require immediate mandatory fallowing

MAGSA’s Groundwater ConditionsMAGSA’s technical consultants have spent the last two years gathering and analyzing data on MAGSA’s groundwater

conditions. Ultimately, the data tells us the amount of groundwater overdraft occurring that must be reduced to achieve sustainability. Over the 20-year Groundwater Sustainability Plan implementation timeline, MAGSA will implement projects and management actions to balance the estimated annual 91,000 acre-feet of overdraft occurring within the agency. MAGSA will take a phased approach to acheiving sustainable groundwater levels.
