Kinzel, P.J., Nelson, J.M., Kennedy, G.W., and Bennion, D., 2019, Hydrographic surveys collected to monitor fish spawning reef placements, Detroit River, Michigan, June 23-24, 2015, U.S. Geological Survey data release,


The U.S. Geological Survey conducted hydrographic surveys from June 23-24, 2015, to monitor fish spawning substrate placements (reefs) in the Detroit River, Michigan. An interferrometric multibeam echosounder was used from the Great Lakes Science Center research vessel Mayfly to collect maps of river bottom topography in locations where spawning substrates have been placed. In addition, baseline topography was collected at locations where substrates were planned to be introduced. The Fighting Island reef had been constructed at the date of survey. Surveys were also conducted at prospective reef sites: Grassy Island, Fort Wayne and Upstream Belle Isle. This data release includes bathymetric surveys collected from June 23-24, 2015.

The Detroit River, which connects Lake St. Clair to Lake Erie, provides 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 the Detroit River 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.
