The Florida Department of Environmental Protection (FDEP) recently tested follow-up water samples collected from Lake Mann near the Gilbert McQueen boat ramp.
It was determined that potentially unsafe concentrations of toxins are still present in the lake.
As a precaution, we are advising everyone to continue to refrain from swimming, recreating and irrigating in/from Lake Mann until further notice.

City of Orlando – Lake Caution for Lake Mann
August 23, 2022
UPDATED Information - The Florida Department of Health (FDOH) in Orange County has extended a Health Caution for the presence of blue-green algae in Lake Mann. This is in response to a site visit and water sample taken by the Florida Department of Environmental Protection (FDEP) on August 16, 2022. The public should exercise caution in and around Lake Mann.
The official toxin determination is obtained from FDEP's data, and until the levels are deemed safe by state standards, the Lake Caution will remain in effect as per FDOH.

For reference, cyanobacteria/blue-green algae are always present in the water, however, not all bacteria have the ability to produce toxins. Toxicity is hard to predict because a single species of algae can have toxic and non-toxic strains. Nothing can be done to treat algae blooms without causing massive fish kills. In the coming weeks, the city will work closely with Florida Department of Environmental Prot
