July update Lake O | Jacqui Thurlow-Lippisch

Northern Lake O algae bloom On Saturday, July 29, 2023, my husband Ed returned from flight with 103 aerial photographs of the St. Lucie River to Lake Okeechobee. When there are so many photographs it is difficult for me to decide which ones to include so I have shared most in gallery format.

The St. Lucie River continues to be darkened by C-23, C-24 and storm water runoff while Lake Okeechobee continues to suffer from cyanobacteria blue-green algae blooms primarily in the north. Ed said there was algae in the middle of the lake but that it was more like a “sheen.” Like gasoline on water.

Ed’s photos show algae on both sides of the St. Luice Canal (C-44), but none at S-80, St. Lucie Locks and Dam, and little visible in the lake -again just a greenish color- at S-308 at Port Mayaca lakeside.

The algae in north Lake Okeechobee is dramatic and looks more clumped than I have witnessed previously. Perhaps wind and rain? Strange…

The only good thing I can say is that the ACOE and SFWMD continue to recommend no discharges from Lake Okeechobee to the St. Lucie River. We’ll see about next week.

On July 25, my brother Todd Thurlow eyeonlakeo texted me that S-308 was open at 1656 cubic feet per second but S-80 remained closed. I would imagine this water let in from the Lake Okeechobee was for canal levels or water supply of agriculture. If I were growing crops I would not wish to accept this water as University of Florida Institute of Food and Agriculture Sciences UF IFAS had notes: “Cyanobacterial toxins can accumulate in crop plants, resulting in injury and yield loss; human health may be affected. Impacts of field crop exposure to cyanotoxins in irrigation water are unknown.”

Known or unknown, it can’t be good.

The historic role of agriculture supported by our state and nation is the primary reason the lake is in such awful condition today; this has been documented since 1969. (U.S. Geological Survey in cooperation with Central and South Florida Flood Control District two year study on chemical and biological conditions of Lake Okeechobee, Beyond the 4th Generation, Lamar Johnson 1974.)

On Saturday, July 29 the South Florida Water Management District recorded the lake level at 15.03 feet. Do not pray for rain…

This past Saturday, July 25, 2020, my husband, Ed, flew across the state to Ft Meyers to visit pilot and fellow River Warrior, Dave Stone. Along for the ride were two other friends, Scott Kuhns and Don Page.

Before the men flew off, I asked the question, like a tape-recorded message: “Could you please take some photos of the algae in Lake Okeechobee?”

“Sure,” Ed replied. “But we’re just going straight across.”

The afternoon went by, and when Ed returned home, my first question was, “Did you see any algae?”

“No,” he answered. “Didn’t you look at the photos I shared?”

I looked at my phone and clicked on the 52 photos. “No visible algae in Lake Okeechobee? Really hunny?

…Where did you guys fly?”

Ed took a long breath. “I told you Jacqui- straight across.”

“What was your altitude?” I shot out.

“About 2000 feet; why are you asking?” Ed looked at me with wide eyes.

“Were you talking to Scott and Don so much that you didn’t really look?” I inquired.

Ed looked me straight in the eye: “Jacqui, we were ALL looking. I told you, there was none, zero, nada.”

“Hmm.” I mused. “Why then aren’t there any photos of the central or west side of the lake?”

“Because there wasn’t any algae!” His final reply.

So today, I share Ed’s photos.

They highlight Port Mayaca at Lake Okeechobee, C-44 Canal, St Lucie Inlet, Hutchinson Island (with a lot of seaweed), Sailfish Flats (seagrass kind of coming back), and Sewall’s Point (with very little seagrass around Bird Island.) Nonetheless, you’ll see that the water itself looks better all around.

And the algae?

It is wonderful that Ed and his friends saw no visible algae.” Really great.

“Visible” though is the key word here. Cyanobacteria is known for its ability to move up and down in the water column. Sunlight is key. My brother Todd’s website eyeonlakeo reveals daily pass satellites Terra, Aqua -there was heavy cloud cover over Lake Okeechobee parts of Thursday, Friday and Saturday.

In 2016, the year the lake was 90% covered in algae, Dr Edward Philips of the University of Florida Dept. of Fisheries and Aquatic Science was quoted in an Okeechobee publication. I thought it explained all so well, I wrote it down:

“Cyanobacteria have gas vesicles which act as buoyancy control devices. The vesicles can be expanded and filled with gas, causing the cyanobacteria to float on the surface, or deflated, which causes the cyanobacteria to descend into the water column. Just because you don’t see it, doesn’t mean there’s nothing going on.”

No Visible Algae in LakeO? Really Hunny?

Ed and I will back up in the air again soon! 🙂
