Summary

In May 2021, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, logged 9 previously drilled boreholes in the bedrock beneath Bull Shoals Dam with acoustic and optical televiewer geophysical methods. The acoustic and optical televiewer logging results were used to identify fractures and small bedding planes in the bedrock beneath the dam using the image and structure interpretation module of Well CAD (v.5.4). This data release consists of each geophysical log in standard log American Standard Code for Information Interchange (ASCII) text (.las) format and a comma separated (.csv) file detailing the fracture and bedding plane analysis completed on each geophysical log.

Purpose

The geophysical logs were collected to improve the understanding of fractures and small bedding planes in the bedrock beneath Bull Shoals Dam. The data are intended for use in forecast models of dam sustainability.
