Sustainable Groundwater Management Act (SGMA)
This basin boundary modification request will allow for efficient implementation of the Sustainable Groundwater Management Act (SGMA) in Sutter, Butte, Colusa, Yolo, and Yuba Counties. Dividing the subbasins along county lines will allow for development and implementation of county-specific plans for sustainable groundwater management.
