Red Tide

On 6/13/25, the FWC reported that the red tide organism, Karenia brevis, was detected at background concentrations in two samples from Southwest Florida; from Manatee and Charlotte counties. 

Blue-Green Algae

On 6/16/25, sampling for cyanobacteria by the Lee County Environmental Lab reported Dolichospermum, Microcystis and cyano filaments as present upstream of the Franklin Locks and at the Davis Boat Ramp, appearing as sparse streaks with accumulation. 

On 6/19/25, satellite imagery of Lake Okeechobee showed the presence of an algal bloom but insufficient data prevented an area from being determined. The previous area of the bloom measured on 6/15/25 was about 160 square miles, or 34% of the lake.
