    • Hydrographic surveys collected to monitor fish spawning reef placements, Detroit and St. Clair Rivers, Michigan, May 2 - 5, 2022

    Metadata Updated: March 11, 2025

    The U.S Geological Survey conducted hydrographic surveys from May 2 - 5, 2022 to monitor fish spawning substrate placements (reefs) in the Detroit and St. Clair Rivers, Michigan. A multibeam echosounder was used from the Great Lakes Science Center research vessel Desmid in to collect the hydrographic data. These data were used to generate maps of river bottom topography in locations where spawning substrates have been placed. The reefs surveyed in the Detroit River included: Fort Wayne, New (East) Belle Isle, Belle Isle, Fighting Island, and Grassy Island. The reefs surveyed in the St. Clair River in 2022 included: Middle Channel, Pointe Aux Chenes, and Harts Light. The data for each study reach were produced in LAS format supported by most geospatial software.
