Sustainable Groundwater Management Program

Sustainable Groundwater Management

The Elsinore Valley Municipal Water District (EVMWD) relies on local groundwater basins for a significant source of its water supply. Recognizing the importance of groundwater to communities like those served by EVMWD, the state legislature enacted the Sustainable Groundwater Management Act of 2014 (SGMA). SGMA provides local water agencies with important new groundwater management tools not previously available for the purpose of achieving sustainable groundwater use.

In order to implement SGMA, the California Department of Water Resources (DWR) has prioritized all of the Designated Groundwater Basins in California as high, medium, low, or very low. In accordance with SGMA, DWR requires the formation of Groundwater Sustainability Agencies (GSAs) that cover the entire basin for all medium and high priority Groundwater Basins. A GSA can be a single agency, or a group of agencies coordinating the sustainable planning and management of the basin.

SGMA enables eligible local agencies to form Groundwater Sustainability Agencies (GSAs), develop Groundwater Sustainability Plans (GSPs) for designated basins in their jurisdiction, and achieve groundwater sustainability within 20 years of GSP implementation. A GSA is responsible for developing and implementing a GSP to meet the sustainability goal of the basin to ensure that it is operating within its sustainable yield, without causing undesirable results.

EVMWD has formed a GSA and has begun the process of developing and implementing a GSP for the Elsinore Valley Subbasin. In order to prepare a prepare a comprehensive GSP, the EVGSA must consider the interests of all beneficial uses and users of groundwater. The EVGSA wishes to learn about your interests in the Elsinore Valley Subbasin and will conduct a series of public workshops for this purpose. EVMWD, in partnership with City of Corona and Temescal Valley Water District, formed the Bedford-Coldwater Groundwater Sustainability Authority, which is also preparing a GSP.

SGMA requires a communications plan to reach and involve the community and stakeholders around the GSP. The District recognizes that this is a critical aspect of ensuring that this process is transparent, engaging, effective, and fully available to the members of the community. Interested community members are encouraged to sign up to receive email updates including notices of upcoming community workshops. The workshop schedule will also be posted on this website. Please email for more information.
