“According to the National Weather Service, there were seven fatalities and 14 rescues on the Great Lakes caused at least partially by currents in the water. Lake Michigan had the most incidents as is typically the case. There are a few reasons why Lake Michigan is the most dangerous year after year. First is the combination of highest population and one of the warmer waters. Second is the shape of the lake which makes it conducive to rip currents.This year did not have as many fatalities and rescues as compared to past years. The main reason for this was the colder summer keeping the number of swimmers down.While currents caused by rip tides are dangerous, the most often cited reason for a rescue is structural. Piers and other structures make dangerous currents and create locations for injuries.While the swimming season may be over, another very dangerous time on the Great Lakes is here. Fall is a season I’ve found to be most dangerous, especially on Saginaw Bay. Some duck hunters and fishers take unwise risks just to shoot a duck or catch a fish.”

Since January, we’ve been busy helping students and educators dive deeper into hands‑on science! This winter, our team supported community engagement at the Step N2 STEM event, the Annual HASTI Conference, at Decatur Classical School, and at the Chicago River Student Congress.
Educators and students joined us to:
🔍 Explored macroinvertebrates up close
🌊 Learned about watersheds through an interactive game
🔬 Investigated plankton under a microscope
🦠 Engineered and raced plankton in the Great Plankton Race
#TeachingTuesday
Celebrate Earth Day with freshwater science and good conversation! Join Illinois-Indiana Sea Grant, the Northwestern Center for Water, Loyola University researcher Tim Hoellein, and IISG’s Sarah Zack for Science Sips: Trash Talk about Chicago Waterways. Learn what research reveals about litter and trash in Lake Michigan and Chicago waterways and what we can do to help.
Plus, enjoy Great Lakes trivia games!

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.
Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.
Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.
