Red Tide

Satellite imagery over the past week has not detected any blooms off the coast of Southwest Florida.


On 9/2/22, the FWC reported that the red tide organism, Karenia brevis was not observed in samples collected statewide.

The Clinic for the Rehabilitation of Wildlife (CROW) on Sanibel received 1 birds with toxicosis symptoms (from red tide or blue-green algae) from 8/30/22 - 9/5/22.

Blue-Green Algae

On 9/6/22 sampling for cyanobacteria by the Lee County Environmental Lab reported the presence of Microcystis at the Alva Boat Ramp, upstream of the Franklin Locks and at the Davis Boat Ramp as sparse specks visible, and with slight accumulation along the Franklin Lock and Davis Boat Ramp seawall.

Data from the FDEP blue-green algae dashboard reported 68 samples collected over the past 30 days for the 10 county area. 1 sample had toxins present. with 0.45 μg per L which is below the EPA recommended standard for recreational waters (8 μg per L).

On 9/7/22, satellite imagery from Lake Okeechobee showed low to moderate bloom potential in the northwestern area of the lake. Overall, algal blooms covered about 155 square miles (22%) of the Lake.
