DWR has updated the Sustainable Groundwater Management Program’s SGMA Data Viewer to include updated subsidence information to help Groundwater Sustainability Agencies (GSAs), water managers, and others implement the Sustainable Groundwater Management Act (SGMA). The data now includes historical subsidence information from 1949 to 2005 and updated satellite based remote sensing InSAR data from June 2015 to June 2018.
