Summary

A backscatter raster generated from multibeam bathymetry and terrestrial lidar collected simultaneously on November 14, 2019. Backscatter is the reflection of a signal and can help when determining bottom types. Harder bottom types (like rock) reflect more sound than softer bottom types (like mud), and smoother bottom types reflect more sound than rugged bottom types.

Purpose

Areas of the Upper Mississippi River System (UMRS) are integrating new science and technology into invasive carp control efforts. Lock and Dam 19, located in Keokuk, IA, is an area where sound deterrents are planned to be installed to help keep invasive carp from moving upstream. This data is used to analyze the lock and dam approach structure.
