A Faulkner County levee west of Conway, Ark. contains a mixture of sand, silt and clay, according to a recent U.S. Geological Survey study.
The results of this study can aid in future maintenance of the Lollie Levee. The findings allow levee managers to identify geologic materials within and below the levee at any location.
“The USGS has provided us with the science to understand our levee, providing valuable information to address future needs,” said Faulkner County Judge, Preston Scroggin.
Results indicate that some parts of the levee are mostly sand, some parts are mostly silt and clay, and some parts are a mixture of materials. The study was prepared in cooperation with Faulkner County, and is available online.
“As the City of Conway moves assets such as the airport into this levee protected area, this study provides valuable baseline data to help maintain the levee in good condition,” said Conway Mayor Tab Townsell.
A geophysical survey and collection of drilling cores from the levee were used to characterize the geologic materials that make up the 6.7 mile long levee. The cores were collected at approximately one mile intervals.
