UPDATE: Lake Alert for Lake Estelle EXTENDED
March 8, 2022 – Recent lab results from a sample collected by the Florida Department of Environmental Protection from Lake Estelle were determined to have potentially unsafe concentrations of toxins present. As a result, Lake Estelle will be closely monitored by the City of Orlando and the FDEP. The City and/or the FDEP will collect samples for analysis at a future date (possibly 4-6 weeks) determined by the FDEP for Lake Estelle and will provide updates on any possible detection of algae toxins as reported on the FDEP Algal Bloom Reporting dashboard ( https://floridadep.gov/AlgalBloom).
Please continue to refrain from irrigating and recreating on the lake, including swimming, fishing and boating until further notice.
Original Lake Alert follows.
On December 27, 2021 the Florida Department of Environmental Protection (FDEP) tested water samples from the Northeastern lobe of Lake Estelle and determined that potentially unsafe concentrations of toxins are present in the lake. As a precaution, the City of Orlando is advising everyone to refrain from swimming, recreating and irrigating in/from Lake Estelle 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 Estelle. Once we obtain more information on the status of the lake, we will continue to update this Lake Alert.
The City and/or the FDEP will collect samples for analysis at a future date (possibly 4-6 weeks) determined by the FDEP for Lake Estelle and will provide updates on any possible detection of algae toxins as reported on the FDEP Algal Bloom Reporting dashboard (
Please encourage your neighbors to register for the Lake Alert at orlando.gov/lakealert so they too will get important information about Lake Estelle directly.
In the meantime, as we stated above, the city would advise refraining from swimming, recreating and irrigating in/from the lake until further notice.
