10/15 UPDATE: This Lake Alert was lifted on October 15, 2021.

Due to a spike in microcystins caused from a recent algae bloom, Lake Holden has been closed to the public.

It was determined by the Florida Department of Environmental Protection that the concentration of microcystins in the lake were at potentially unsafe levels and as such, all water contact activities must cease until further notice.

The spike in toxins is caused by seasonal “flipping” which you can learn more about below.


A lot of #orlando lakes are being shut down lately and we’ve got the 411 on why! Have a question about Orlando? Slip into our dms and ask!

  1. In the last 2 months, Lake Alerts have also been issued for Lakes Highland, Formosa, Rowena, Estelle, and Ivanhoe for microcystins. All but Ivanhoe and Rowena had their Alerts released. But the City is leaving warning signs up in all of the lakes.
