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 contains trackline navigation for approximately 2300 kilometers of multibeam echosounder bathymetry and backscatter data collected by the U.S. Geological Survey during cruise 2017-049-FA on Lake Powell in the Glen Canyon National Recreation Area. This information can help spatially correlate the bathymetry and backscatter data with other geophysical data.
