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 500 shot point navigation and unique shot point navigation for approximately 92 km of chirp seismic-reflection data collected by the U.S. Geological Survey during survey 2017-049-FA along the San Juan Arm and Good Hope Bay to Hite sections of Lake Powell in the Glen Canyon National Recreation Area. This information allows for spatial correlation of chirp seismic-reflection profiles images with other geophysical and sample data for investigating lake-floor morphology and stratigraphy in the area.
