Lake Okeechobee Levels & Caloosahatchee Flow Impacts

On 1/11/23 Lake Okeechobee was at 16.28 feet, decreasing by 0.07 feet in the past week. The weekly average flow at S-79 was 1,646 cfs (cubic feet per second) and flow from the Lake at S-77 was an average of 1,205 cfs. The 14-day average flow at S-79 was 1,802 cfs and has been in the optimum flow envelope (750 - 2,100cfs) for 13 days.

Red Tide

Satellite imagery over the past week has detected low to medium concentrations of chlorophyll off the coast of Southwest Florida.

On 1/11/23, the FWC reported the red tide organism, Karenia brevis, was detected in 72 samples collected from and offshore of Southwest Florida over the past week. Bloom concentrations (>100,000 cells/liter) were present in 16 samples: one offshore of Pinellas County, seven in Manatee County, two in Sarasota County, two offshore of Charlotte County, two offshore of Collier County, and two offshore of Monroe County.

K. brevis was observed at background to medium concentrations in and offshore of Pinellas County, background concentrations in Hillsborough County, background to medium concentrations in Manatee County, background to medium concentrations in Sarasota County, low to medium concentrations in and offshore of Charlotte County, background concentrations in Lee County, background to high concentrations offshore of Collier County, and medium concentrations offshore of Monroe County.

The Clinic for the Rehabilitation of Wildlife (CROW) (currently displaced off island) received 2 birds with toxicosis symptoms (from red tide or blue-green algae) from 1/3/23 - 1/9/23.

Beach Conditions

The City of Sanibel reported 10 deceased birds found on the beach during a beach cleanup including 1 double crested cormorant, 3 brown pelicans, 2 royal terns, 2 laughing gulls, 1 greater yellowlegs, and 1 unknown fowl. SCCF reported 1 deceased common loon on Bunche Beach on 1/9/23. (Cause unknown.)

Blue-Green Algae

On 1/9/23 sampling for cyanobacteria by the Lee County Environmental Lab reported the presence of Microcystis upstream of the Franklin Locks and at the Davis Boat Ramp as sparse specks.

On 1/11/23, satellite imagery from Lake Okeechobee showed patchy low to medium potential in the lake.

SCCF wants to know when and where all types of algae sightings occur to monitor conditions around the islands and to investigate algae bloom occurrence with patterns in seasonal weather changes and Lake Okeechobee water management practices.

Download the algae reporting app on your phone by clicking here or by searching for the ArcGIS Survey123 app in the app store. Once installed, give the app permission to access your phone’s location to receive GPS coordinates of your sighting and camera/media to capture and attach pictures. When you open the app, click “Continue Without Signing In.”

Next, download the algae reporting survey by scanning the QR code above or clicking here on your phone. Once the survey is downloaded, fill out the required fields and click the check mark in the lower right corner to submit your sighting. Note: If you do not have cellular coverage, you can still fill out the survey and save it in the outbox to be sent later.
