Hydrographic surveys and acoustic Doppler current profiler measurements collected to monitor fish spawning reef placements, Detroit and St. Clair Rivers, Michigan, September 13-16, 2021 and May 2-5, 2022 The U.S Geological Survey conducted hydrographic surveys from September 13-16, 2021 and May 2-5, 2022 to monitor fish spawning substrate placements (reefs) in the Detroit and St. Clair Rivers, Michigan. This work was conducted as part of a reimbursable agreement with the Environmental Protection Agency to provide technical assistance in areas of concern. A multibeam echosounder was used from the Great Lakes Science Center research vessel Cisco in 2021 and Desmid in 2022 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 in 2021 included: Fort Wayne, New (East) Belle Isle,...

Three sediment samples were collected upstream of the artificial spawning reefs constructed in the Middle Channel and two on the reefs themselves.The bed sediment samples were dried and sieved at 1/2 phi increments to determine their grain-size distribution.
