Blue-Green Algae

On 2/23/26, sampling for cyanobacteria by the Lee County Environmental Lab reported Microcystis, Dolichospermum and cyano filaments as present at the Davis Boat Ramp as slight accumulation and as moderately abundant upstream of the Franklin Locks, as streaks with accumulation. At the Alva Boat Ramp, mainly cyano filaments, some Dolichospermum and some Microcystis were present appearing as cloudy green water.

On 2/25/26 satellite imagery of Lake Okeechobee showed the presence of an algal bloom covering about 40 square miles or 9% of the lake.
