SGMA Background
On September 16, 2014, Governor Brown signed into law a package of bills (SB-1168, AB-1739 and SB-1319 (PDF)) collectively called the Sustainable Groundwater Management Act (PDF). The Sustainable Groundwater Management Act (SGMA) comprehensively reforms groundwater management in California. The intent of the Act is to place management at the local level under state oversight. Under the Act, the state will have direct oversight of how groundwater basins are managed at the local level and may intervene to manage basins when local agencies fail to take appropriate responsibility.
For general SGMA background, check out the Water Education Foundation's SGMA Handbook (PDF) or visit the Groundwater Exchange website.
Although a state law, SGMA is implemented locally within groundwater subbasins. Butte County is located in portions of three subbasins: Vina, Butte, and Wyandotte Creek.
To find your local subbasin and Groundwater Sustainability Agency (GSA) information visit the GSA Map Viewer.
