Two Planes; One Algae Bloom? SLR/IRL

Ed, my husband, and Todd my brother, algae hunters! The Cub.
The Baron, Todd and Ed. All of Todd’s photos are linked at the bottom of this post.

On Saturday, my husband, Ed, took my brother, Todd, up in both the Cub and the Baron to look for a the large algae bloom Ed and I had seen last Wednesday in Lake Okeechobee. I went along for the Baron ride, but the Cub only holds two.

Maybe you, like me, after listening to the news the past few days, realized there were other blooms reported, even a “small one” in Pahokee on May 20th by famed biologist Barry Rosen, of USGA. I wondered if Todd and Ed would see more blooms, other blooms…

Saturday, July 22, 2017, was much more overcast than the previous Wednesday, so the lake photos Todd took are not as bright in color, but the “southwest of Port Mayaca” bloom is definitely still there. Todd did not report any others during the trip and the GPS track shows that he and Ed went quite far north and west. (Channel 12 reported on two blooms on Lake O’s western shore…)

Before the flight, Todd also shared the most recent Landsat 8 satellite image that shows where the large “southwest of Port Mayaca” bloom is located although here too, there are a lot of clouds blocking the image…

After Wednesday’ s post, many were asking me  if there were visible blooms in the St Lucie River or C-44 Canal.

The answer: “No.” From 1000 feet up, there are none visible. But there are the “bubble like nutrient swirls” that seem to proceed the blooms in some areas.  (You’ll notice these in Todd’s photos and all 350+ photos are linked at end of post.)

I did notice that on Facebook a small bloom was reported at Rivers’ Landing in Palm City, and another one on rocks in the North Fork. The Caloosahatchee has indeed reported a pretty significant bloom…blooms are in the estuaries but the motherload is Lake O.

Have you seen any blooms? If so, here is the link to report algae blooms to the Department of Environmental Protection, “DEP.”

It is important to report what you see!

http://www.dep.state.fl.us/central/Home/Watershed/ReportProblem.htm

I happened to notice when I visited the DEP website that DEP states:  “Blooms are naturally occurring.”

…Yes this is true; so is cancer.

However, nutrient pollution that feeds these algae blooms and is killing our estuaries, and possibly us, is entirely man-made. We know what causes it.

We must be more diligent and creative in stopping the nutrient run of from agriculture and development. “Taking measures”as noted in the DEP quote as the game plan just isn’t enough. After all, this is a war to save our Florida.

“There are no short term solutions to rectifying the situation; this is a naturally occurring phenomenon that the State monitors closely. However, the state is taking measures that in the long-term will reduce nutrient loading and improve water quality.” DEP, 2017 website

South Fork that connects to C-44 and then Lake O  at Port Mayaca,  near Palm City; following photos just going west towards Lake Okeechobee. Notice the bubble trails.

American Yachts and 195 overpass is near where C-44 connects to South Fork of St Lucie River
S-80 where area basin water is allowed into South Fork of St Lucie as well as water from Lake O if S-308 is open at Port Mayaca
Part of C-44 Reservoir project, the biggest in the state, to hold area basin water, clean and return to C-44.

C-44 is “running backwards” into Lake O right now, dark color is visible
Algae is present south west of Port Mayaca but not as bright on this cloudy day…

Photo in 2nd plane, the Baron. I went along for this one as you can get a more overall view…
Again algae present in Lake O southwest waters but not as intense as seen in blog photos I published four days prior as this day was cloudy and there was little sunlight.
My brother noted the algae around the Okeechobee Waterway canal cut into the lake. Interesting!
The water flowing backwards from C-44 area basin is certainly one of the things fouling Lake Okeechobee.

“Algae Hunters” Track Significant Bloom Living in the Middle of Lake Okeechobee, SLR/IRL

My husband and I have decided we are algae hunters…

Hello Readers. Hope you are having a good summer!

Even though I am supposed to be on a “blogcation,” my husband, Ed, and I decided to fly over Lake Okeechobee this morning as yesterday Dr Susan Gray of the South Florida Water Management District reported on the Army Corp of Engineer Periodic Scientist Call that recent Landsat Satellite images had revealed significant algae in the middle of the lake- – – an area known as “LZ40.”

Sure enough, once Ed  and I got up in the air, just a few miles west of Port Mayaca, the strings of bright green algae were visible from about 1000 feet —-looking down— up to as far as eye could see…

Very strange to be surrounded by water and bright-colored lines of algae; it resembled  miles of suspended fluorescent paint. I have heard the scientists talking about how the algae comes up in the morning for sunlight and then goes back down into the water column later in the day. It is  intelligent, like an animal, and knows how to hide. You have to track it….

The living bloom was quite extensive, going on for many miles. My photos do not do the color or amount justice, but do document. This is important.

Thank God the ACOE is not dumping into the St Lucie River/Indian River Lagoon this summer. Poor lake O, on the other hand, has been getting “backwards flowing” C-44 water and back-pumped water from the EAA, STAs, and WCAs. No wonder its a mess!

Thank you to the SFWMD for the heads up! We do appreciate your work. We have inherited and created “quite an animal.”

See everyone soon.

NOTE OF INTEREST:

*Reader, Professor Geoff Norris recommends we ask NOAA to create a bulletin for Lake O like this one here for Lake Erie since basically we are “in the same boat:” I think this is a great idea. I will have to contact NOAA.
