The dataset contains the locations for the periodic groundwater elevation monitoring stations that track seasonal and long-term groundwater elevation trends within the California Central Valley. The groundwater level measurements contain time-series data at sites managed by the DWR and local monitoring entities. This dataset is available for download on the SGMA Data Viewer web app, CNRA Open Data Platform, and the CASGEM web application. The data was used for the calibration of the C2VSimFG to perform quality control. Not all of these observed data were used in the calibration of the C2VSimFG due to the insufficient or questionable groundwater observations, such as observed data in subregion 10 and 14, where observed groundwater levels within the area of the Corcoran Clay Layers are highly variable. The groundwater elevation data went through an extensive data review process to determine the CASGEM wells used for the calibration of C2VSimFG. For questions/comments contact gis@water.ca.gov.
