Summary

High-resolution geophysical mapping of Lake Powell in the Glen Canyon National Recreation Area in Utah and Arizona was conducted between October 8 and November 15, 2017, as part of a collaborative effort between the U.S. Geological Survey and the Bureau of Reclamation to provide high-quality data needed to reassess the area-capacity tables for the Lake Powell reservoir. Seismic data collected during this survey can help to define the rates of deposition within the San Juan and Colorado Rivers, which are the main inflows to Lake Powell. These new data are intended to improve water budget management decisions that affect the natural and recreational resources of the reservoir. Multibeam echosounder bathymetry and backscatter data were [...]

Purpose

This dataset is used to display the locations of sound velocity profiles (SVP, also referred to as sound speed profiles), as well as the SVP data, collected during a 2017 USGS survey on Lake Powell in the Glen Canyon National Recreation Area of Utah and Arizona. The sound velocity profiles document water column sound speed variability during the survey, and were used during processing to account for refraction artifacts present within the multibeam bathymetric data. The dataset contains graphs of sound velocity vs. depth at each profile location, as well as a shapefile with the location in Geographic Coordinate System (GCS) WGS 84 latitude and longitude, the time of day, and date of collection.
