Summary

The U.S Geological Survey conducted hydrographic surveys from July 23-25, 2018 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 hydrographic data. These data were used to generate maps of river bottom topography in locations where spawning substrates have been placed. Reefs that had been constructed at the time of survey in the Detroit River included: Fighting Island, Fort Wayne, New (East) Belle Isle, Belle Isle, and Grassy Island. The reefs constructed in the St. Clair River at the time of survey included: Middle Channel, Pointe aux Chenes, and Harts Light.

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. 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.
