The Sutter Groundwater Subbasin is generally described as being in the “central portion of the Sacramento Valley Groundwater Basin” in DWR’s Bulletin 118 (California’s Groundwater). It is bounded on the north by the confluence of Butte Creek and the Sacramento River and Sutter Buttes, on the west by the Sacramento River, on the south by the confluence of the Sacramento River and the Sutter Bypass, and on the east by the Feather River and the eastern boundary with the Sutter-Yuba County line.
SGMA defines groundwater sustainability as “the management and use of groundwater in a manner that can be maintained during the planning and implementation horizon without causing undesirable results.” What does this mean? A sustainable groundwater basin is one in which the water use is balanced with the water replenishment from rainfall, surface water, and other sources and water quality is maintained to meet all designated beneficial uses.
The earth has limited supplies of water. Groundwater and surface water are essentially one resource, physically connected by the water cycle, in which water evaporates, forms clouds, and falls to the ground as rain or snow. Some of this precipitation seeps into the ground and becomes groundwater that moves slowly into an underground aquifer. If there is no precipitation, then there is no water returning to the groundwater basin and the groundwater supply is not “recharged” or refilled.
The Sutter Subbasin has been managed for many years under the Sutter County Groundwater Management Plan to ensure the quantity and quality of groundwater in the county is sustained. The nine GSAs that manage the basin are currently collaborating on a Groundwater Sustainability Plan (or GSP) in accordance with the Sustainable Groundwater Management Act (SGMA).

The Sustainable Groundwater Management Act, signed into law in 2014, provides a framework for long-term sustainable groundwater management across California. It requires that local and regional authorities in medium- and high-priority groundwater basins form a locally-controlled and governed Groundwater Sustainability Agency (GSA), which will prepare and implement a Groundwater Sustainability Plan (GSP).
Not directly. Sustainable groundwater management, much like management of surface water resources, is the result of a long-term vision and commitment by one or more water users or communities. That said, now that the State has faced several consecutive years of drought, the need to manage groundwater is more relevant than ever. Some California groundwater basins have reached an all-time historic low. Creating a framework for state oversight ensures a standard, consistent process to maintain and actively monitor and manage basins at the local level, and reduce impacts seen from overuse of these basins.
Over the years, the California water managers, individual well owners, and communities that rely on groundwater resources have observed a rapid decline of water levels in some aquifers. Impacts and issues related to the decline is apparent. For example, some wells in California have experienced declines in excess of 10 feet during the drought and increases in groundwater pumping have exacerbated some areas of land subsidence, which also threatens infrastructure such as roads, canals and bridges.
In January 2014, the Governor’s Office identified groundwater management as one of ten key action steps in its California Water Action Plan. SGMA, signed into law months later, follows up on that action, giving local agencies the ability to manage their respective basins following statewide guidelines.
SGMA does not change existing groundwater rights. Groundwater rights will continue to be subject to regulation under Article 10, Section 2, of the California Constitution.
SGMA provides a framework for the improved management of groundwater supplies by local authorities. In fact, it specifically limits state intervention provided that local agencies develop and implement groundwater sustainability plans as required by the legislation. Under SGMA, local agencies now have tools and authorities some agencies previously lacked to manage for sustainability.
Under a limited set of circumstances, the State Water Board may step in to help protect local groundwater resources. The process of State Water Board intervention is sometimes referred to as the State Backstop or State Intervention, and only occurs if local efforts to form a GSA or prepare a viable GSP are not successful.
If local agencies fail to form a GSA by July 1, 2017, local groundwater users must begin reporting groundwater use to the State Water Board. State Intervention requirements then remain in place until local efforts are able to sustainably manage groundwater resources.
A Groundwater Sustainability Agency (GSA) is one or more local governmental agencies that implement the provisions of SGMA. A local agency is defined as one that has water supply, water management or land management authority. The primary purpose of a GSA under SGMA is to develop and implement a Groundwater Sustainability Plan (GSP) or Alternative Plan to achieve long-term groundwater sustainability.
The first requirement of SGMA was to form a GSA by June 2017. The Sutter Subbasin consists of nine GSAs who each submitted an application to become a GSA for different portions of the Subbasin. Since establishing as GSAs, these agencies have been working together on sustainable groundwater management. See map below for more information on the area covered by each GSA within the Subbasin. Sutter Subbasin GSAs include:
Under SGMA, GSAs are empowered to:
The GSA may use a number of management tools to achieve sustainability goals. The specific tools and methods the GSA will use to achieve sustainability will be determined in discussion with stakeholders and identified in the GSP.
It is also important to note that SGMA requires local agencies to acknowledge Groundwater Sustainability Plans when a legislative body is adopting or substantially amending its General Plan. General Plans must accurately reflect the information in the Groundwater Sustainability Plan with regards to available water supplies.
As public entities, the local agencies joining together to form a GSA will review the formation process and GSP adoption process as part of their regularly noticed public meetings. The agencies also anticipate conducting workshops and creating other opportunities for input.
The nine GSA agencies are working together under a Memorandum of Understanding (MOU) as the Sutter Subbasin Groundwater Management Coordination Committee (SSGMCC). The SSGMCC is comprised of representatives from each of the nine GSAs within the Subbasin and generally follows a consensus-based decision-making structure where each GSA representative receives an equal voice. The SSGMCC holds regular coordination meetings to discuss GSP technical development and public outreach and engagement activities in order to prepare a GSP for ultimate adoption by the respective GSA Boards.
Each GSA must decide on the which governance structure to adopt. Common governance structures for GSAs include the use of a Memorandum of Agreement or a Joint Powers Authority.
The California Department of Water Resources (DWR) is the agency responsible for oversight of the GSAs and GSPs formation. DWR has a list of regulations, objectives and actions formulated to assist local agencies and GSAs with the preparation and implementation of GSPs. Under law, all regulations adopted by DWR only become effective only upon approval by the California Water Commission. Under a limited set of circumstances, the State Water Board may intervene if local efforts to form a GSA or prepare a viable GSP are not successful.
The regulations require that all GSAs coordinate with adjacent GSAs in a given basin. This coordination will occur through additional discussions with neighboring agencies as GSAs are formally developed, and the GSPs will describe how the adjacent GSAs will work together to achieve groundwater sustainability.
Not directly. However, this new groundwater management framework acknowledges the connectivity of surface water and groundwater, and that they are to be managed as “a single resource.”
A GSP is the plan of a GSA that provides for sustainably managed groundwater that meets the requirements of SGMA. GSAs in high and medium priority groundwater basins are required to submit a GSP to the California Department of Water Resources. The plan must outline how the GSA will implement, manage and measure specific actions for the health and viability of the basins. DWR will evaluate the GSP and provide the GSA with an assessment of the plan and any necessary recommendations every two years following its establishment.
All GSPs must be completed and begun to be implemented by January 31, 2022.
SGMA strongly encourages closer planning coordination between water supply and land use agencies to ensure water supply planning accurately forecasts and secures water supplies for future land use changes, and that land use planning considers the effects of projected growth on water resource management. Local agencies are required to acknowledge GSPs when a legislative body is adopting or substantially amending its General Plan. General Plans must accurately reflect the information in the GSP with regards to available water supplies. In addition, a city or county must now refer the proposed adoption or substantial amendment of a General Plan to any affected GSA(s). In response, the GSA(s) must provide the land use agency with the current version of its GSP and any information that is relevant to determining the adequacy of existing and planned future water supplies to meet existing and planned future demands.
Public workshops will be held to update interested residents and stakeholders about the GSP Development process. The public workshops will include presentations on data, information, and analysis compiled for the planning process, as well as activities to solicit input and feedback from participants on plan direction. We invite all interested residents, businesses, and public agencies to join us and provide input at our public workshops which are listed here. Additionally, all meetings held by the Sutter Subbasin Groundwater Management Coordination Committee are open to the public, and all interested parties are encouraged to attend. Finally, you can sign up for our mailing list here and receive regular updates regarding GSP development and notices of upcoming meetings. (Note, this information can also be found on this website.)
