On March 23, 2022, the Florida Department of Environmental Protection (FDEP) tested water samples from Lake Mann, taken by the Gilbert McQueen boat ramp, and determined that potentially unsafe concentrations of toxins are present in the lake. As a precaution, we are advising everyone to refrain from swimming, recreating and irrigating in/from Lake Mann until further notice.

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 Protection (FDEP) to monitor Lake Mann. Once we obtain more information on the status of the lake, we will continue to update this Lake Alert.
