Barb Gajewski grew up on a lake that discovered invasive Eurasian water milfoil, an aquatic invasive plant, in 2001. She was fresh out of college when the lake owners hired her to track the plant's spread and hand-pull any invasive milfoil she found -- launching her career in lake management. (1/2)

We're glad everyone survived this incident in South Haven. Some crucial lessons from this MLive story:
1. Piers close for a reason. Don't push your luck 🌊
2. Waterfronts are best explored with a buddy -- keep an eye on each other 👀
2. Safety gear in public places can save lives! 🛟

Great Lakes water levels decline from record highs: What the forecast says The recent decline in Great Lakes water levels hasn't been especially steep, but the overall trajectory is one of increasing variability.

Over the next six months, the Army Corps predicts water levels will stay below long-term averages on all Great Lakes, except possibly Lake Ontario. planetdetroit.org/2026/03/grea...
