The St Lucie Canal, also known as, the C-44 Canal, is the property of the U.S. Government. Martin County public records show that in the early 1930s, as a result of the 1928 hurricane, the right of way of the Everglades Drainage District was taken as part of the Okeechobee Waterway.
The U.S. Army Corp of Engineers holds jurisdiction and decision making over the canal and the water that flows through it from basins and Lake Okeechobee. Since the great flood of 1947 and the creation of the Central and Southern Florida Plan, there has been a “local partner” in decision making. That partner today is named the South Florida Water Management District, formerly the Everglades Drainage District…
In a modern world, every week, there are conditions calls regarding Lake Okeechobee and the environmental envelope, etc. As in all things, these calls start with the “higher ups” and then end with a public call. The public call is the ACOE Periodic Scientist Call. During this call, stakeholders share conditions and concerns from all over south and central Florida. Most participants are government people or elected officials, but also heads of NGOs and members of the public chime in.
The process generally works as such: after all these calls, the SFWMD, the local sponsor, puts out an operations statement or recommendation to the ACOE. All of this information is available on line, but its like trying to find a needle in hay stack.
Of course the ACOE and the SFWMD have been communicating all week. At the end of the day, because the U.S. ACOE holds jurisdiction over the C-44 Canal the ACOE is the final decision maker. More than ever, though, they are listening and even seeking public input. This is refreshing!
The ACOEs has been announcing their decision on the Jacksonville District’s media call on Friday of the week of all the other calls. This past Friday, the day after the SFWMD operations report was submitted, and all the “calls”, January 20, 2023, the ACOE held its media call, and the decision to start discharging from Lake Okeechobee was made make Col. Booth.
Going back a couple of years, Col. Kelly, at the ACOE, came up with an operations plan called a HAB DEVIATION or Harmful Algae Bloom Deviation. This was done after Governor Ron DeSantis put forth Executive Order 19-12 that did all possible to avoid harmful and toxic discharges to the northern estuaries, St Lucie and Caloosahatcee, as years 2013, 2016 and 2018 had been disasters. HAB DEVIATIONS, like all things Army Corp, is engineering-like and complicated, but goal was to allow a deviation from lake operations (LORS or LOSOM) if there was algae in the lake or it was possible there could be algae in the lake, like after a Category 4 hurricane stirs everything up and brings massive runoff…
I am not sure if what the ACOE is doing now qualifies as a technical HAB Deviation, but it is certainly in the spirit of one. Both SFWMD and ACOE have stated they are expecting a large post Ian cyanobacteria blue-green algae bloom in Lake Okeechobee this summer. High lake water in summer would set off releases so they are hopefully dodging a bullet by lowing the lake now.
Due to Hurricane Ian, a Category 4 storm, that obliterated the lower west coast of Florida, coming in just north of Sanibel Island and Ft Meyers, Lake Okeechobee has risen four feet since September 28, 2022 cresting at around 16.47 feet. Because the Herbert Hoover Dike was almost complete, the ACOE did not discharge right away. If the lake had been at the 15.50 limit as before dike completion, there would have been discharges, input or no input.
Yesterday, January 25, 2023, was the ribbon-cutting for the Herbert Hoover Dike Rehabilitation. It took eighteen years. This does not mean there is unlimited allowance of water in Lake Okeechobee, but it allows for more flexibility as will LOSOM. Sediment has been settling in the lake since September/October.
I for one, appreciate the flexibility of the ACOE. In the old world when I entered in 2008, they just followed the book and opened the gates toxic algae or no toxic algae. Now there is awareness and thought. And water quality remains the responsibility of the state. If the ACOE believe/agree a HAB deviation is necessary after a Category 4 hurricane in order to try to avoid toxic discharges in summer when the lake often cooks into a toxic soup, I am all for it. I do not want to go through those type of years again!
These charts below from my brother Todd’s eyeonlakeo.com website show how water was discharged to the St Lucie in 2016, 2018, 2021, and 2022. Although the ACOE is discharging at 500 cfs average now to the SLR, all will be done to avoid another “Lost Summer!”
2018 Lost Summer 3
2021 nice summer even with LO releases (green)
2022 great summer, no releases LO
Photos of Ed Lippisch taken on Sunday, January 22, 2022, the day the 500 cfs discharges began to the St Lucie. These photos are baseline photos to compare to the future. I takes a day or more for discharge water to reach the St Lucie Inlet. The differences in these photos is due to tide and light.

Thanks Jacqui for another very informative update. Hopefully the process continues to make careful decisions about discharges to minimize our continuing challenges to our water quality.
BTW, I know NOAA and others report Ian landfall as occurring north of Sanibel.
Let there be no doubt and all satellite imagery from September 28 and all physical evidence clearly show the entire 10-15 mile stretch of Sanibel coastline is where Ian came ashore. We took one for the team this time 🙂
Such a terrible hurricane was Ian. I am so sorry. The SFWMD told me it came in at Coya Costa but storm surge so high if really hit “everywhere.”
I understand this is necessary, but why aren’t the discharges going into the C-44 reservoir?
I heard the reservoir is not functioning yet. They are still running tests on it.
Yes. Right. It should be approved by July or so but mind you it was really made for cleaning of basin water.
Dear Diane, the c-44 reservoir is not approved for safety by ACOE yet ( July hopefully) and it was not constructed for LO discharges but rather to clean c44 basin runoff. Maybe some LO water is mentioned “to sell/“but that was not original purpose. The EAA reservoir is for lake water (50%) but it won’t be enough for all Lake o water and won’t be complete until 2030 hopefully. I know this is depressing. It is a slow go.
A manatee was trying to eat the growths on my dock pilings this morning. It went from piling to piling looking for something to scrape off the dock pilings. Is that normal behavior? Or is the poor thing starving to death from lack of sea grass.
Probably normal – I have seen same in Flamingo but definitely they don’t have enough seagrass to eat.
But you don’t mention the reservoir, which I thought was ready.
The C-44 Reservoir is not approved by ACOE for safety measures as of yet. Should be by July or so. They make sure it does not leak. Also although people talk about this for Lake O water, the original design was to clean basin C-44 water not Lake O water. The EAA Reservoir will collect about half of its size in Lake O water and it should be done by 2030. The ACOE is breaking ground this February. The STA built by the SFWMD will be complete this year. I know. It’s exhausting. So long to fix all this mess.
The water looks like filthy sewage all week. It’s so disgusting. It can’t be healthy for anyone that lives close to the water to be breathing that in.
