This data release contains spatial data associated with the bathymetric survey and sedimentation analysis of Lago Carite in January 2018. During January 23-30, 2018, the U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, conducted a bathymetric survey of Lago Carite primarily to update estimates of the contemporary reservoir storage capacity and sedimentation rate. Previously designated transect lines were surveyed by using a depth sounder coupled to a differential geographic positioning system to generate a bottom contour map and, ultimately, the stage-storage relation for Lago Carite. This data release consisted of three items: bathymetric contours, water-depth data points and the shoreline of Lago Carite used for the analysis. A total of 137 planned transect lines were surveyed, and over 269,119 water-depth measurements were made across the reservoir. All water-depth data were collected using a Teledyne-Odom Echotrac CVM depth sounder coupled to a differential Global Positioning System (GPS). Esri ArcGIS, version 10.5 (reference similar to that in metadata for point shapefile), was used to edit the depth data and create a triangulated irregular network (TIN) model, from which bathymetric contours and a stage-volume relation were generated.
