Summary

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, Michigan. A multibeam echosounder was used from the Great Lakes Science Center research vessel Cisco 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, and Grassy Island. The reefs surveyed in the St. Clair River in 2021 included: Middle Channel, Pointe Aux Chenes, and Harts Light. The data for each study reach were produced in LAS format supported by most geospatial [...]

Purpose

The Detroit and St. Clair Rivers provide habitat to a number of fish species including walleye (Sander vitreus), lake white-fish (Coregonus clupeaformis), and lake sturgeon (Acipenser fulvescens). These fish rely upon clean rock-rubble on the river bottom for spawning. The availability of rocky spawning habitat in these rivers has been significantly reduced by the dredging of shipping channels. Therefore, increasing the availability of rock-rubble spawning habitat, through the placement of artificial substrate (reefs), is one strategy that has been adopted by stakeholders to increase fish populations. These habitat enhancements represent a significant investment in planning, permitting and construction. Where river processes deposit sediment and cover the substrate, its value as fish spawning habitat can be diminished. Therefore, it is crucial in the site selection process that substrate be placed in locations that benefit the fish species of concern and, to the extent possible, ensure its longevity and ecological function. Potential changes in river bed elevation in these locations due to infilling by bedload sediment could be determined through serial hydrographic surveys.
