Spatial Data for the Sedimentation Survey of Lago Lucchetti, Yauco, Puerto Rico, September 2013-May 2014

The U.S. Geological Survey conducted a sedimentation survey of Lago Lucchetti, Yauco, Puerto Rico, in 201314 in cooperation with the Puerto Rico Aqueduct and Sewer Authority. This dataset in shapefile format was generated from the survey data. The 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. The results of the 201314 survey indicated a total storage capacity for Lago Lucchetti of 10.21 million cubic meters and a long-term sedimentation rate loss of 0.17 million cubic meters per year based on the original capacity in 1952. Sediment accumulation was about 10.14 million cubic meters, which represents a storage decrease of about 50 percent of the original capacity in 1952. On the basis of the comparison between the 201314 and 2000 surveys, the useful life for Lago Lucchetti is projected to end in 2074.
