Lake Okeechobee’s latest algae scare: What’s really going on?

Every summer, Florida’s giant Lake Okeechobee turns into a floating soup of blue-green algae. Officials just flagged another bloom on June 19, warning people—and pets—to stay out of the water. This isn’t new. Warm, still water mixed with extra nutrients turns the lake into a perfect algae breeding ground, and the warnings roll in almost every year.The latest alert came after a water test on June 16 showed harmful toxins. But how bad is it really? Past years like 2016 and 2018 saw huge blooms covering most of the lake, turning water neon green and forcing emergencies. Even in years without such extremes, smaller blooms still pop up, making parts of the lake unsafe for months. The real question: Why does this keep happening? Experts say sunlight, heat, and pollution—especially from farm runoff—feed the algae. When it spreads, it can poison wildlife, irritate skin, and even make the air smell bad. The health advice is simple: don’t swim, don’t drink the water, and keep animals away. But is that enough?
