Hydrographic surveys collected to monitor fish spawning reef placements, Detroit and St. Clair Rivers, Michigan, September 13-16, 2021

Metadata Updated: October 29, 2023

The U.S Geological Survey conducted hydrographic surveys from September 13-16, 2021 to monitor fish spawning substrate placements (reefs) in the Detroit and St. Clair Rivers, MI. A multibeam echosounder was used from the Great Lakes Science Center research vessel Cisco to collect 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, and Grassy Island. The reefs surveyed in the St. Clair River 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.
