Photo was taken on 4/1/24 at 1:15 PM on a rising tide (2.1 ft). The 14-day average flow at S-79 was 4,225 cfs.

Red Tide

On 3/29/24, the FWC reported that the red tide organism, Karenia brevis, was observed at background concentrations in one sample collected from Florida’s East Coast over the past week. In Southwest Florida over the past week, K. brevis was not observed

The Clinic for the Rehabilitation of Wildlife (CROW) received 2 birds with toxicosis symptoms (from red tide or blue-green algae) from 3/26/24 - 4/1/24.

Blue-Green Algae

On 4/1/24 sampling for cyanobacteria by the Lee County Environmental Lab reported the presence of Dolichospermum and miscellaneous cyano-filaments at the Alva Boat Ramp with streaks and a pale green tint to the water. Dolichospermum and Microcystis were abundant upstream of the Franklin Locks as streaks and small clumps with heavy accumulation along the lock. Dolichospermum, Microcystis, and Raphidiopsis were moderately abundant at the Davis Boat Ramp as streaks with some accumulation. Dolichospermum and miscellaneous cyanofilaments were moderately abundant at North Shore Park as specks. Dolichospermum was moderately abundant at the Midpoint Bridge Park with accumulation along the shore.
