In November 2021, seven Groundwater Sustainability Agencies (GSAs) in the Cosumnes Subbasin formed the Cosumnes Groundwater Authority (CGA). With the responsibility of implementing the Cosumnes Subbasin Groundwater Sustainability Plan, CGA strives to be a hub of information regarding groundwater sustainability within the Cosumnes Subbasin.
