The County of San Luis Obispo, Cities of Atascadero and Paso Robles, Templeton Community Services District, Atascadero Mutual Water Company, and other entities have formed a Groundwater Sustainability Agency (GSA) for the Atascadero Basin in accordance with the Sustainable Groundwater Management Act (SGMA).  The purpose of the agency is to develop a SGMA-compliant Groundwater Sustainability Plan (GSP) for the basin.
