Algae Alert on Lake Superior | Duluth News

Barker’s Island Beach in Superior is closed due to toxic blue-green algae—a growing threat signaling deeper trouble for Lake Superior. Usually cold and nutrient-poor, the lake is warming faster than most, creating conditions ripe for blooms that can harm people, pets, and ecosystems. Since 2012, these annual outbreaks are becoming a warning sign. Experts from U.S. and Canada convened a summit to tackle the crisis, urging more research and funding before it mirrors Lake Erie’s fate. Good news? It’s not too late—join a public panel next Tuesday at UW-Superior to hear their findings and ask questions. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
