TALLAHASSEE, Fla. — The Florida Department of Health in Leon County (DOH Leon), The Florida Department of Environmental Protection (DEP), and Leon County Government are responding to a blue-green algae Health Alert at Lake Munson. This is in response to water samples taken on May 18, 2022.

Laboratory analysis found low level toxins present. Following a recommendation from DOH Leon, Leon County Government in coordination with the Department has agreed to close the boat ramps until further notice. The public should exercise caution in and around Lake Munson.

Residents and visitors are advised to take the following precautions around Lake Munson:
• Do not drink, swim, wade, use personal watercraft, water ski, or boat in waters where there is a visible algae bloom. Do not get water in your eyes, nose, or mouth.
• Wash your skin and clothing with soap and water if you have contact with algae or discolored or smelly water.
• Keep pets away from the area. Waters where there are algae blooms are not safe for animals. Pets and livestock should have a different source of water when algae blooms are present.
• Do not cook or clean dishes with water contaminated by algae blooms. Boiling the water will not eliminate the toxins.
• Eating fillets from healthy fish caught in freshwater lakes experiencing blooms is safe. Rinse fish fillets with tap or bottled water, throw out the guts and cook fish well.
• Do not eat shellfish in waters with algae blooms.

Blue-green algae can occur wherever conditions are favorable for their growth. Warm, nutrient rich water, or changes in water flow are factors that often contribute to algal blooms. While blooms may not be as commonplace in northern Florida as in the warmer climates of south Florida, they can and do occur throughout the state, and have been observed in Leon County in the past. Prior blooms in Leon County sampled by DEP can be viewed on their Algal Blooms Dashboard
