Sedimentation survey data for Lago Guayabal, December 2017
This data release contains spatial data associated with the sedimentation survey of Lago Guayabal conducted during the period December 11- December 14, 2017 by the Puerto Rico office of the Caribbean-Florida Water Science Center (CFWSC) 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 data collection involved measuring water depth along predetermined navigation lines. More than 270,000 water-depth points were surveyed along 60 navigation lines and All water-depth data were collected using a Teledyne-Odom Echotrac CVM depth sounder coupled to a Global Positioning System (GPS). Esri ArcGIS software, version 10.5 (Environmental Systems Research Institute, 2017), 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. This data release includes three spatial features used for the sedimentation analysis of Lago Guayabal in 2017 (water depth data points, reservoir shoreline and bathymetric contours).

Sedimentation survey of Lago Guayabal, Villalba, Puerto Rico, December 2017
The U.S. Geological Survey, in cooperation with the Puerto Rico Electric Power Authority, conducted a sedimentation survey of Lago Guayabal in 2017 to determine reservoir infill sedimentation rates, generate a bathymetric map of the bottom elevations of the reservoir, and create a stage-volume relation. The original (1913) capacity of Lago Guayabal was 11.82 million cubic meters, and efforts to in - Connect
