Blue-green algae are a type of bacteria found in lakes in Kentucky and throughout the United States. They occur naturally, but if their numbers get too high they can pose health risks to humans and animals. When present in high concentrations, they can be referred to as Harmful Algal Blooms or HAB’s. Anglers, hunters, boaters and all others who might use these water resources should be aware of the potential risks associated with these blooms. Both the Kentucky Division of Water and the U.S. Army Corps have initiated increased testing of lakes in Kentucky to document these blooms and provide updated information to the public.
