Bear Valley Basin

Groundwater Sustainability Plan


Protecting an Important Resource for our Community

During a normal year, groundwater provides over 35 percent of Southern California’s drinking water. Effective use of local groundwater basins is an important component of the region’s water supply plan. 

On September 16, 2014, Governor Jerry Brown signed into law the Sustainable Groundwater Management Act (SGMA), creating California’s first framework for sustainable, groundwater management. SGMA empowers local agencies to form Groundwater Sustainability Agencies (GSAs) to manage basins sustainably. The legislation requires those GSAs to adopt Groundwater Sustainability Plans (GSPs) for crucial groundwater basins in California.

Several agencies worked together to develop a GSP for the Bear Valley Basin. The GSP was approved by the Bear Valley Basin GSA on June 21, 2022. 

Below is a more detailed description of the project, the Groundwater Sustainability Agency, and SGMA. To learn even more, visit our Frequently Asked Questions

In an effort to ensure the sustainable use of California’s groundwater and a water secure future for the State, SGMA was signed into law in 2014. The Act took effect in 2015. 

​For the first time in California’s history, SGMA requires groundwater resources be sustainably managed by local agencies through the formation of Groundwater Sustainability Agencies (GSAs) in basins that are deemed high- or medium-priority by the Department of Water Resources. 

​In such basins, GSAs are required to develop and implement Groundwater Sustainability Plans. These plans must quantify basin characteristics and supplies, and must establish management actions and projects to achieve basin sustainability within 20 years of implementation. SGMA imposes many new monitoring and reporting requirements, and other procedural and substantive mandates related to groundwater management.


Here the details of how the GSP will be managed and enforced by the GSA are outlined.

Profile the Basin geology, groundwater use, and all factorse affecting future groundwater demand and management.

Set measureable goals per SGMA requirements and the systems/networks to monitor progress.

Identify the projects and management actions to be taken to meet the sustainability goals.

The GSA votes to adopt the Groundwater Sustainability Plan (GSP).

Groundwater Sustainability Plan (GSP) — A management plan developed by a local Groundwater Sustainability Agency (GSA) to provide a framework in managing the groundwater basin sustainably and to meet the requirements of SGMA.
