Data points, corresponding to the bathymetric survey of Lago Guayabal, Puerto Rico, December 2017

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...

Bathymetric survey of Levittown Lake, Toa Baja, Puerto Rico, January 2011

This child item contains the spatial data associated with the bathymetric survey of the Levittown lake, conducted on January 11, 2011. The child item consist of two datasets: 1) contours of the lake bottom and 2) data points colleced along each established navigation line, to calculate the water volume of the lake at mean sea level. A bathymetric/land survey system (BLASS) interfaced to a depth sounder was used to conduct the survey. The system consists of a Global Positioning System (GPS) and a digital depth sounder. Geographic location and water depth data were simultaneously collected and stored in a portable computer. The data were then transferred into the USGS geographic information system (GIS) for processing...

This data release contains data for the hydrologic and water-quality characterization of Levittown Lake, from April 2010 to June 2021. Three child items were included in the data release to summarize the results of the (1) community productivity through the light and dark bottle method (2) two diel data collection efforts, and (3) spatial data associated with the bathymetric survey conducted at Levittown Lake to contour the lake bottom. Diel studies were conducted at the lake to estimate the community net primary productivity, the respiration rate, and the gross productivity rate. Two diel studies were conducted on November 18, 2010, and May 18, 2011, near the respective annual periods of highest and lowest tides...

Bathymetric contours of Lago Guayabal, Puerto Rico, December 2017

This dataset is a polyline shapefile containing bathymetric contours, at 1-meter intervals, of Lago Guayabal, Villalba, Puerto Rico. 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-López (2008) and Wilson and Richards (2006). More than 270,000 water-depth points were surveyed...

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...
