UPDATE : Lake Alert for Lake Highland
The Lake Alert for Lake Highland has been lifted. Please resume all normal water activities associated with the lake.
Original Lake Alert:
On December 30, 2020, City of Orlando staff took samples from Lake Highland that detected the presence of microcystins (toxins) at levels deemed unsafe by state standards. As a precaution, we are advising everyone to refrain from swimming, recreating and irrigating in/from Lake Highland until further notice.
These conditions are caused by algae blooms that could be a result of several factors, including warmer water and excessive nutrients that can come from a combination of fertilizers, septic tanks, yard waste and pet waste.
Because of the potential for harm to humans and pets, city staff will continue routine testing until the algae bloom declines and toxin levels are reduced to acceptable state standards. The city will keep the Lake Alert in place until conditions are deemed to be safe. Please encourage your neighbors to register for the Lake Alert at cityoforlando.net/lakealert so they too will get important information about Lake Highland directly.
