Groundwater Sustainability Agencies in Santa Barbara County

In Santa Barbara County, basins that are subject to the Sustainable Groundwater Management Act (SGMA) include all medium and high priority basins, as defined by the State Department of Water Resources (DWR), that have not previously been adjudicated. Under SGMA, agencies in each of these basins were required to form  Groundwater Sustainability Agencys (GSA) and have begun the process of drafting Groundwater Sustainability Plans (GSPs). 

More information on SGMA and GSAs can be found on DWR's website. Information on specific basins follows:
