On a hot and summer evening in 1988, a group of researchers from the University of Windsor boarded a small vessel on Lake St. Clair to do a local survey of freshwater species. Upon inspecting a bucket of rocks from the bottom, a young graduate student discovered an unknown species that would soon become so prolific throughout the Great Lakes that it would threaten water quality and health of Great Lakes fisheries, and would cost businesses, governments, and landowners over $100 million annually.
