The contours were generated from bathymetric data collected during a sedimentation survey conducted during the period December 11- December 14, 2017 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-L\u00f3pez (2008) and Wilson and Richards (2006). More than 270,000 water-depth points were surveyed along 60 navigation lines  used in previous sedimentation surveys (Soler-L\u00f3pez, 2003, 2008). 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 . \nReferences: \nSoler-L\u00f3pez, L.R., 2003, Sedimentation History of Lago Guayabal, Puerto Rico, 1913-2001: U.S. Geological Survey Water-Resources Investigations Report 03-4198, 28 p, 2 pls.\nSoler-L\u00f3pez, L.R., 2008, Comparison of Storage Capacity and Sedimentation Trends of Lago Guayabal, Puerto Rico, December 2001 and October 2006: U.S. Geological Survey Scientific Investigation Map 2008-3016, 1 sheet \nWilson, G.L., and Richards, J.M., 2006, Procedural Documentation and Accuracy Assessment of Bathymetric Map and Area/Capacity Tables for Small Reservoirs, U.S. Geological Survey-Scientific Investigation Report 2006-5208, 24 p. plus oversize figs,https://pubs.usgs.gov/sir/2006/5208/pdf/SIR-06-5208.pdf.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9FD12Y5", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5cf7ae77e4b07f02a7046429.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5cf7ae77e4b07f02a7046429", "keyword": ["Bathymetry and Elevation", "GNIS ID 1611313", "Geographic Names Informaion System", "Juana Diaz County", "Lago Guayabal", "Puerto Rico", "Small-scale Datasets - Contours", "USGS:5cf7ae77e4b07f02a7046429", "Villalba County", "bathymetry", "contouring"], "modified": "2020-08-12T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-66.508331205, 18.085445171, -66.492469206, 18.099361746", "theme": ["geospatial"], "title": "Bathymetric contours of Lago Guayabal, Puerto Rico, December 2017"}
