Summary

This data release contains spatial data associated the sedimentation survey conducted by the U.S. Geological Survey cfor the Lago La Plata, Toa Alta, Puerto Rico, during March and April 2015 to provide up-to-date information about the relation of pool elevation and storage volume in the reservoir. The survey was conducted in cooperation with the Puerto Rico Aqueduct and Sewer Authority. A total of 264 navigation lines were surveyed, using a depth sounding device coupled to a global positioning system. The results of the survey were used to prepare a bathymetric map showing the reservoir bottom referenced with respect to the spillway elevation.

Purpose

The hydrographic data was collected to provide an update of the reservoir storage capacity and sedimentation rate using established navigation lines that serve as reference paths, beginning at the dam structure and continuing upstream along the longitudinal extent of the reservoir. The collected data were transferred to the geographic information system (GIS) developed by ESRI ArcGIS for post processing and to calculate reservoir volume. Data points collected along each established navigation line were used to generate a bathymetric map representing the reservoir bottom
