Dangerous Green Cloud Spreads Over Michigan Lake

A sudden surge of algae has appeared in Center Lake, located in southern Michigan, prompting alarms among local health officials. The growth—known as a harmful algal bloom (HAB)—can release toxins that threaten people, pets, and wildlife. While illnesses from such blooms are uncommon, they can be serious or even deadly according to federal guidelines.

What It Looks Like

The bloom manifests as a vivid green film that resembles spilled paint or floating scum. It spreads across the surface, creating streaks and clumps that make the water look unnaturally bright.

Health Department Advisory

The Jackson County Health Department advises residents to steer clear of the affected waters and shorelines. Activities such as swimming, jet skiing, boating, or fishing in these zones are strongly discouraged.

“Only the polluted sections pose a risk,” the department’s social media post emphasized. “Unaffected areas remain safe for recreation.”

Residents are urged to keep pets away from the lake and monitor local updates for any changes.

Broader Context

Earlier this month, similar blooms were reported in other Michigan lakes such as Lake Orion, Proud Lake, and Walled Lake. These incidents highlight a growing pattern of algal outbreaks across the state’s freshwater systems, prompting increased vigilance from health authorities.
