Overview 

__________________________________________________________________________________________________________

The Sustainable Groundwater Management Act (SGMA) was passed into California law in fall of 2014 and took effect in January 2015. SGMA requires that state-designated medium and high-priority basins and sub-basins must form a groundwater sustainability agency and develop a long-term GSP. In Kern County, the designated basins/sub-basins are Indian Wells Valley Sub-basin, Kern County Sub-basin, and Cuyama Valley Basin. These basins must comply with SGMA.
