This dataset consists of a shapefile of points corresponding to water depth collected for the bathymetric survey of Puerto Mosquito, in Isla de Vieques, Puerto Rico, on August 11, 2015. The U.S. Geological Survey, in cooperation with the Puerto Rico Environmental Quality Board, conducted a limnological study at Puerto Mosquito in Vieques to assess the principal mechanisms affecting the hydrology and water quality characteristics. The study characterized hydrologic and physical-chemical properties, sediment deposition rates, bathymetry, and biological conditions. The bathymetric survey system used for the study consisted of coupling a global positioning system (GPS) device with a water depth sounder. Established navigation lines were used to simultaneously collect the water depth and geographic location data using a bathymetric system. A bathymetric map was generated by transferring collected data into a geographic information system (GIS).

The U.S. Geological Survey conducted a sedimentation survey of Lago Lucchetti, Yauco, Puerto Rico, in 2013–14 in cooperation with the Puerto Rico Aqueduct and Sewer Authority. This dataset contains the bathymetric data points collected in this survey. This survey updated previous surveys, conducted in 2000, and provided accurate information regarding reservoir storage capacity and sedimentation rate using bathymetric techniques, coupling global positioning system and a depth sounder device.

This dataset is a point shapefile containing water-depth points collected during a sedimention 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 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. More than 270,000 water-depth points were surveyed along 60 navigation lines used in previous sedimentation surveys (Soler-Lopez, 2003, 2007, 2008). 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 dataset contains the data points collected during the bathymetric survey of Lago Caonillas between September and November 2012 by U.S. Geological Survey. The 2012 bathymetric survey was conducted using a bathymetric/land survey system, consisting of a global positioning system (GPS) coupled to a digital depth sounder. A total of 155 survey navigation lines were established at 50 meter (m) intervals, beginning at the dam and continuing upstream along the river branches of the reservoir. Geographic position (accuracy of less than 2 m) and water depths (accuracy of 2 centimeters [cm] ±1 percent of the measured depth) were acquired simultaneously using the GPS interfaced to the depth sounder. The fathometer was calibrated prior to each day of survey by using a bar check. Data points collected on September 2012 for Lago Caonillas were adjusted to represent depth relative to the spillway elevation (251.76 meters above mean sea level). However, data collected during November 2012 was not adjusted since the water elevation at the reservoir was at the crest of the spillway structure. The reservoir pool elevation was monitored at the continuous recording USGS lake-level monitoring station 50026140 Lago Caonillas at damsite near Utuado, Puerto Rico. Lago Caonillas is owned and operated by the Puerto Rico Electric Power Authority (PREPA) since 1996. Because of the importance of Lago Caonillas to the North Coast Superaqueduct, the U.S. Geological Survey (USGS), in cooperation with PRASA, conducted a sedimentation survey of Lago Caonillas between September and November 2012 to update estimates of the reservoir’s storage capacity.
