Side-scan sonar to document lake trout spawning habitat at offshore reefs in northwest Lake Michigan

LMBS biologist Will Stacy-Duffy recently gave a presentation at a virtual conference hosted by GLOS (the Great Lakes Observing System- The Conference was called “Lakebed 2030” in reference to their initiative to map the bathymetry of the Great Lakes in high resolution by 2030 and brought together a diverse group of researchers who do lakebed mapping for various purposes. For the “Fisheries/Habitat” perspective, Will discussed how we use bathymetry and substrate mapping to document lake trout spawning habitat and aid the management and restoration of the species.
