Pale green algae coated the shoreline and the surface of Doctors Lake in July 2018.

The Florida Department of Health is warning of potentially toxic blue-green algae in Doctors Lake at Pace Island in Clay County.

Not all blue-green algae blooms are toxic, but it’s important to assume they are until scientists can test the water.

That means avoiding direct contact with the water and keeping pets away as well. Also, don’t eat any shellfish from the affected water, but it is safe to eat fish caught there, as long as it’s rinsed.

Blue-green algae are a type of bacteria that is common in Florida’s freshwater environments. A bloom occurs when rapid growth of algae leads to an accumulation of individual cells that discolor water and often produce floating mats that emit unpleasant odors.

Sunny days, warm water temperatures, still water conditions and excess nutrient all contribute to blue-green algae blooms. Bloom can occur all year, but they are more frequent in summer and fall.
