UPDATE: November 29, 2016 – The Lake Alert issued for Lake Olive has been lifted based on the absence of toxins from additional testing performed by City staff. Resume normal activities on the lake.


The City of Orlando Streets and Stormwater Division has issued a Lake Alert for Lake Olive.

The City took samples of lake water once it was made aware of an “unusual appearance” in Lake Olive, just off Summerlin Avenue in Thornton Park [GMap]. The samples tested positive for microsystin toxins and anatoxins, at unsafe levels. Both toxins are created by Cyanobacteria, more information available HERE.

The City is asking residents to avoid swimming, recreating, and irrigating in/from Lake Olive until further notice. They also stated, “Please be aware that as the algae dies, a “musty” or other unpleasant odor may occur.”

The City will continue to perform routine testing until the algae bloom declines and toxin level are reduced to acceptable state standards.
