Bathymetric contours of Lago Carite, Puerto Rico, January 2018

This dataset is a polyline shapefile containing bathymetric contours, at 1-meter intervals, of Lago Carite, Puerto Rico. The contours were generated from bathymetric data collected during a sedimentation survey conducted during the period January 23 - January 30, 2018 by the Puerto Rico office of the Caribbean-Florida Water Science Center of the U.S. Geological Survey (USGS). The goals of the survey were to determine reservoir infill sedimentation rates, generate a bathymetric map of the reservoir, and create a stage-volume relation. Field techniques used during the survey were similar to those outlined by Soler-López and Carrasquillo-Nieves, (2001) and Wilson and Richards (2006).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 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.
