Blue-green algae at TEAGUE BAY (REEF BEACH)
TEAGUE BAY (REEF BEACH) is a lake in St. Croix Island County, U.S. Virgin Islands. 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.
