Blue-green algae at Prairie Harbor Yacht Club

Prairie Harbor Yacht Club is a lake in Kenosha County, Wisconsin. Blue-green algae are not currently monitored at this water.

Blue-green algae (cyanobacteria) blooms are most common from midsummer into early fall, when the water is warm, calm, and rich in nutrients from runoff. They can produce toxins that make people sick and can be rapidly fatal to dogs, so skip water that looks green, scummy, or like spilled paint, and keep children and pets out of it.
