June 15, 2022

UPDATED Information- A Lake Alert for Lake Silver was issued on January 31, 2022, due to a potentially unsafe concentration of toxins present in the lake. City of Orlando Stormwater staff have been continuously monitoring Lake Silver since the Lake Alert was issued. This message is to provide an update on the status of the lake.

The results from the latest sampling event performed by City of Orlando staff on June 15, 2022, indicate there are no toxins present in the lake at this time. However, out of a preponderance of caution, the City is electing to keep the Lake Alert in effect until city staff performs one (1) additional sampling event to ensure the bloom subsides and the lake does not produce additional toxins. Lake Silver will continue to be closely monitored by City of Orlando staff. The lake will be resampled again at the end of June, after the sampling event, we will provide another update. At this time, the Lake Alert remains in effect until further notice.

Please continue to call the Lake Alert number, 407.246.2220, for the most up-to-date information regarding your lake. During weekdays, the City's Lake Alert website, orlando.gov/lakealert will also have the latest information.


Original Lake Alert Notice below

On January 31, 2022, City of Orlando Streets and Stormwater staff tested water samples from Lake Silver 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 Silver 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 continue to monitor Lake Silver. Once we obtain more information on the status of the lake, we will continue to update this Lake Alert.
