Cape Coral Warns of Blue-Green Algae at Jaycee Park

June 28, 2023

The city of Cape Coral has posted signage at Jaycee Park warning visitors of the presence of potentially toxic blue-green algae. Blue-green algae was reported at several locations in the Caloosahatchee River, including at Jaycee Park. Water samples are being tested for toxins and the results will be available on the state’s Algal Bloom Dashboard. The City will communicate these results once available.

City officials encourage the public to exercise caution when near waterways, even if the presence of toxins has not yet been confirmed.

The City routinely monitors for the presence of harmful algae and potential toxins within Cape Coral’s waterways using a private contractor. County and State partners also monitor these conditions. The City is working to deter the presence of blue-green algae in Cape Coral’s canals by activating bubble curtains during the incoming tides.

The City reminds residents that pet waste, grass clippings, and fertilizers containing nitrogen or phosphorus entering waterways can worsen algal blooms. The use of fertilizers containing nitrogen or phosphorus is not permitted between June 1 and Sept. 30, and grass clippings should be disposed of as horticulture waste.
