    • Consumer-Grade Side-Scan Sonar Imagery of Invasive Silver Carp in a Missouri River Oxbow Lake, Creve Coeur Lake, 2023 September 20

    Metadata Updated: September 13, 2025

    In September 2023, the USGS demonstrated the use of side-scan sonar to image large densities of invasive carp in Creve Coeur Lake, Maryland Heights, Missouri, USA. A 400-meter reach was surveyed using a Humminbird Helix sonar system. Proprietary sonar data were converted to PNG image files (i.e., rectified and speed-corrected) using SonarTRX Pro. The resulting data set includes one CSV file, original side-scan sonar images (PNG files), speed corrected side-scan images (correcting distortions in imagery due to small changes in boat velocity; PNG files), and a KMZ file of original rectified images for a mosaic display in Google Earth Pro.
