“The report notes that this small population would have a greater than 50 percent chance of successfully spawning if they were to find a viable river access point to the lakes. Lake Michigan is the most likely target, and the Chicago Area Waterway System of rivers, sanitary canals and locks would be the most likely entry point. Already, the environmental DNA of carp has been detected as close as six miles from Lake Michigan. Some worry that the carp’s entrance into the Great Lakes is inevitable.”

Some partnerships just make sense. Happy Valentine’s Day from IISG! 💕
This February marks a major milestone: 30 years of aquatic invasive species outreach by our team! To celebrate, IISG Director, Stuart Carlton, and Strategic Communication Coordinator, Renie Miles, sat down for a Sea Grant Chat with two key figures in IISG’s AIS history: Pat Charlebois, our assistant director and program leader, who spent over two decades leading our prevention efforts, and Katie O’Reilly, who took over that role in 2022. We discussed the evolution of the invasive species issue in the Great Lakes, the shift toward understanding human behavior, and the creative strategies that make this team so effective.
