Algae Overview North, South, East, West LakeO

Because the Baron needs hours on the engine, my husband Ed and I have been up in the sky a lot lately. Sometimes I am with him and sometimes I am not, but through technology we are always connected. 

Today I am sharing all aerials Ed took yesterday, 6-17-20, that continue to document a very expansive algae bloom in Lake Okeechobee. 

So where exactly is the algae? I can tell you, from the sky, flying over the central and southern part of the lake -at two, to five thousand feet -going two-hundred miles per hours -it sometimes becomes one giant blur of green. Right now, the bloom is visible mostly in the south central (east, west and central) areas of the lake, not in the north.

Seeing the algae depends on lighting and some areas are brighter than others, but when the sun hits the water just right, a sheen is everywhere.

About a mile and a half off Port Mayaca’s S-308 on the east side is the brightest and weirdest of all often displaying geometric formations due to boat traffic through the channel.

The ACOE has been flowing C-44 into the lake at S-308 but this certainly is not the cause of all the algae. Ed and I have years of documentation. The lake is eutrophic. Winds also affect the collection and formation of the algae. For a deeper dive into this you can visit my brother Todd Thurlow’s website EyeOnLakeO.

Here are all photos 6-17-20 with some comment clues and GPS. I have made one comment and then all photos that follow are the same location just a different angle. Use the GPS too. Question? Just ask!

ACOE 2016 Inflows & Outflows/If Only There Were NoFlows…SLR/IRL

ACOE Col. Kirk  2015-present

Thank you to John Campbell, Public Affairs Specialist, Army Corp of Engineers, for these numbers comparing “flows” for 2016, 2015, and 2013.  I have been using since last week when presenting and wanted to share. Note, there were no flows (discharges from Lake Okeechobee to the St Lucie River) in 2014 and that is why the year is not reported. The Corp has announced their intent to further decrease flows in the coming weeks as they transition to the dry season. Hurricane, or wet season, comes to an end on November 30th.

All numbers are important but a very important # is how much water is going south…

2016 Flows, JAN 1-OCT 23 (Number of inches based on estimate that 1 foot of Lake O water is about 460,000 acre feet)

Direct Rain 1.85 million ac-ft (48 inches)
Other inflows 3.32 million ac-ft (86 inches)

Moore Haven 1.61 million ac-ft (42 inches)
Franklin 2.39 million ac-ft

St. Lucie
Port Mayaca 630,000 ac-ft (19 inches)
St. Lucie 730,000 ac-ft

South 550,000 ac-ft (14 inches)
Evap/seep/other 1.86 million ac-ft (48 inches)

2015 flows, JAN 1-DEC 31
Direct Rain 1.48 million ac-ft (38 inches)
Other inflows 2.45 million ac-ft (63 inches)

Moore Haven 590,000 ac-ft (15 inches)
Franklin 1.21 million ac-ft

St. Lucie
Port Mayaca 120,000 ac-ft (2 inches)
St. Lucie 190,000 ac-ft

South 1.28 million ac-ft (33 inches)
Evap/seep/other 2.14 million ac-ft (55 inches)

2013 Flows, MAY 8-OCT 21 Inflows/Rain-(Not available at time of request)
Moore Haven 1.02 million ac-ft (26 inches)
Franklin 2.15 million ac-ft

St. Lucie
Port Mayaca 402,000 ac-ft (10 inches)
St. Lucie 663,000 ac-ft

South 166,000 ac-ft (4 inches)
