I posted most of these photos on Facebook, but today I will give explanations and document on my blog. From above, our St Lucie/Indian River Lagoon remains beautiful, but we must be sensitive to the losses beneath the waters. These aerials were taken during a “slack tide” between 12 and 2pm on December 9, 2020 by my husband, Ed Lippisch. December 9th was the last of five days the ACOE stopped discharging from Lake Okeechobee; however S-80 was discharging “local runoff.” (Click on chart above.) Unfortunately, due to high lake level and lack of storage reservoirs, since these aerials were taken, the ACOE has begun ramping up Lake discharges once again.
Below Lawrence Glenn of the South Florid Water Management gives a comprehensive ecological report covering low-salinities and loss of oyster spat in the St Lucie and other aspects, positive and negative, for the entire Everglades system.

Ed Lippisch, selfie. Thank you Ed!
As you can tell, I have lots of people helping me. Whether it is Ed flying or my brother Todd who provides an incredible easy to read website called EyeonLakeO. You can click below to check it out. The more we know, the more we document, the more we can overturn the destruction of our beloved estuary…
Executive Order 19-12 “What can we do to achieve more now for Florida’s Environment?”
Sometimes all the bureaucracy of water management makes it difficult to understand how things work. Today, I am going to summarize the goals and requirements of Governor DeSantis’ Executive Order 19-12 Section 1, C. in hopes of giving some simple insight into the responsibility of our state agencies to publicly come together to achieve the Governor’s goal; there are only six months remaining.
On January 10th, 2019, just days after being sworn into office, Governor DeSantis put forth Executive Order 19-12. This order has multiple components, but today, we will focus on Section 1, C:
It states: “Update and secure all restoration plans, within one year, for waterbodies impacting Soth Florida communities, including Lake Okeechobee, the Caloosahatchee, and the St Lucie Estuaries. These updates will ensure the Blue-Green Algae Task Force has the necessary information to provide guidance to the Department of Environmental Protection on maximizing the investments in water quality improvements.
This means that the Basin Management Actions Plans, the system the state uses to try to improve water quality through lessening phosphorus and or nitrogen runoff have to be “updated” by January 10, 2020.
Prior to the Governor’s Executive Order 19-12, there was no unified update date, nor a clear deadline date. Why? Because state statute doesn’t give one. How come? Because over the years special interest has lobbied our state legislature to make it this way. Governor DeSantis’ order complicates this by giving a hard deadline to find out how these BMAPS are working or not working.
An update is an “update on the status of implementation at the end of the first phase and an opportunity to provide recommendations for future phases of the BMAP.”
The three Basin Management Actions Plans that need to be updated include the Okeechobee BMAP; the St Lucie BMAP and the Caloosahatchee BMAP.
The agencies that oversee this process are the Department of Environmental Protection (regulation of water quality standards); the Dept of Agriculture and Consumer Services (BMPs or Best Management Practices); and the South Florida Water Management District (water quantity or “projects)
You will see as you read about these BMAPS they are more of a soft than hard science. These maps were developed to meet a “total maximum daily load” reduction of phosphorus and or nitrogen, overtime – like 20 or 30 years!
To do this, basins and stakeholders are identified, and best management practices for agriculture and other stakeholders are implemented. Then the Dept of Environmental Protection models how much the best management practice will help remove phosphorus and or nitrogen and a certain amount of credit is given for using the Best Management Practice.
It’s kind of like giving a grade based on participation instead of performance. It’s time to raise the bar. In order for the Blue-Green Algae Task Force to have the necessary information to provide guidance to the Department of Environmental Protection on maximizing the investments in water quality improvements,” we must truly know the numbers.
~Monitoring not Modeling!
P.S. Why are the three BMAPs together in the executive order? Lake O is discharged into the St Lucie River and Caloosahatchee so for them to meet their goals, Lake Okeechobee has to meet its goals. For now, we are all connected.
What should be normal, was a gift on Christmas Day, blue water in the St Lucie River/Indian River Lagoon. The peninsula of Sewall’s Point shone like the gem it is surrounded by aquamarine on both sides: the St Lucie River on its west, and the Indian River Lagoon on its east…
Feeling like the Bahamas, rather than the toxic-sludge we had to endure ~coming mostly from Lake Okeechobee this past summer, 2018, and yes, remember 2016, and 2013….the destruction must stop!
As 2019 edges into the picture, we will once again have to give everything we have to fight for clean water and encourage our state and federal government to support legislation “sending the water south.”
Seeing these beautiful blue waters once again is certainly encouraging. Now to keep the Army Corp and South Florida Water Management District at bay long enough, as projects proceed, and allow our precious seagrass beds to return so baby fish can once again hide, swim, and grow to maturity in these waters; once christened the “most bio-diverse in North America.”
Thank you to my dear husband, Ed, for these photos all taken 12-25-18. And from both of us, “Merry Christmas!”

Sometimes the history of the Everglades is really confusing. Why, with all of the environmental advocacy, since the 1970s, does the health of our environment remain crippled? One way to simplify it is to think in terms of before and after the 1947 U.S. Central and South Florida Plan. Of course there is extensive history before 1947, but it was after 1947 that things in South Florida’s water world became culturalized, compartmentalized, and legally defined. Before we talk about this 1947 Central and South Florida Plan, let’s review some important highlights pre-1947.
1. Hamilton Disston begins the drainage of Lake Okeechobee (1881)
2. Governor Napoleon Broward hires U.S.D.A. scientist James Wright who determines that “eight canals would indeed drain 1,850,000 acres of swampland” (1904)
3. The U.S. Congress’ Rivers and Harbors Act includes significant funds to deepen the manmade Hamilton Disston connection of the Calooshahatchee River to Lake Okeechobee (ca.1910)
4. The scandal of James Wright (from #2 above) who was deemed “a fraud” for the failure of the land to drain as expected ~causing the slump in swampy real estate sales (1914)
5. The resurgence of confidence in sales and a 1920s real estate boom fueled by advances in soil science, and the success of agricultural start-ups located in Moore Haven, Belle Glade, and Clewiston south of Lake Okeechobee
6. Land in a defined “Everglades Drainage District” more fully being systematically cut into sections for development with canals draining agricultural fertilizers and other chemicals into the waters of the state (1924)
6. Two very powerful hurricanes causing thousands of deaths and the destruction of property, and thus the state’s “call for a higher dike” (1926 and 1928)
7. The state’s reaction to the hurricanes, the 1929 establishment of the “Okeechobee Flood Control District” for the “Everglades Drainage District” as well as the Federal Government’s Army Corp of Engineers taking over “field operations”around Lake Okeechobee ~including the building of a thirty-five foot earthen dike and ingeniously using navigation funding to build the cross-state-canal, connecting the Caloosahatchee and the St Lucie Estuaries to Lake Okeechobee ~conveniently working as discharge-escapes through those estuaries when “necessary”
So, as we can see, a lot happened pre-1947, but it was what happened after, were things really changed…
In 1947 it rained and rained, and there were two hurricanes. From Orlando to Florida Bay the agricultural and developed lands, that had been built in drained, once marshy, swampy areas, really flooded, and in some places a foot of water sat for months. There was great economic loss.
The crying cow booklet, above, was sent to every member of the U.S. Congress.
To fight Florida’s destructive “flood waters” the 1948 U.S. Congress adopted legislation for the CENTRAL AND SOUTH FLORIDA PROJECT, a twenty year flood plan from Orlando to Florida Bay that included the formal creation and protection of the Everglades Agricultural Area south of Lake O, the Water Conservation Areas, intertwined with thousands of miles of canals and structures to control the once headwaters and River of Grass. HOUSE DOCUMENT 643 – 80TH CONGRESS (00570762xBA9D6)
Next, mirroring the same terminology the United States Government had used (the Central and South Florid Project) the state of Florida created the “Central and South Florida Flood Control District” to manage that CENTRAL and SOUTH FLORIDA PROJECT. A bit confusing huh? A tongue twister. And in a way one could say, at that time, the Central and South Florida Project and the Central and South Florida Flood Control District “became one.” The overall goal above all other things was flood control. And this marriage of the Central and South Florida Project and the Central and South Florida Flood Control District was successful at controlling the waters, but it also killed the natural environment, thus Florida herself.
This embedded cultural philosophy of “flood control only” was challenged in 1972 with the birth of the national environmental movement, and a consciousness that the natural system that supported Florida’s tourism, quality of life, agriculture, not to mention valuable wildlife, was in tremendous decline.

The Army Corp of Engineers has lessened but not stopped Lake O discharges that started September 20th, 2017 just prior to Hurricane Irma. Perhaps as the discharges have gone on at such a high rate for a comparatively long time, the plume has had a chance to extend its territory. In yesterday’s photos, the dark, filthy plume is reaching clearly south beyond the exclusive Town of Jupiter Island.
Yesterday was a beautiful day, but the river and ocean waters of our entire region were ugly, possibly contaminated. How are we to enjoy our property and lives here?
When viewing the aerials below, please note the blue, sapphire-colored water just on the edge of the discharge plume. Yes, of course all estuaries put forth darkened fresh water after a rain event, and Ed and I could see this occurring just south at Jupiter Inlet. Nonetheless, the black, gigantic plume that we repeatedly endure for the St Lucie River/Indian River Lagoon due to discharges from Lake Okeechobee is an aberration.
Please let’s all support Joe Negron and the public’s work to build the EAA Reservoir; clean & send the water south!
These aerial photos over the St Lucie Inlet were taken by my husband, Ed Lippisch, Sunday, October 29, 2017, at 1:45pm.
The number one issue here is the polluted waters of Lake Okeechobee being forced into the SLR/IRL because they are blocked by the Everglades Agricultural Area from going south.
The ACOE has been discharging Lake O waters into the St Lucie since mid-September. These over-nutrified and sediment filled waters continue to destroy our economy and ecology on top of all the channelized agricultural and development waters of C-23, C-24 and C-25. Stormwater from our yards and streets also adds to this filthy cocktail.
Near shore reefs, sea grasses, oysters, fish? A human being? Better not have a cut on your hand…Not even a crab has an easy time living in this.
We move forward pushing the SFWMD and ACOE for the EAA Reservoir with these sad photos and the fact that our waters are putrid at the most beautiful time of year as motivation. We will prevail. One foot in front of the other.
Today is October 7th, 2017 and I am sharing photos taken October 6th, 2017 in the area of the St Lucie Inlet displaying the recent discharges from Lake Okeechobee and area canals. The plume was measured four miles out, this is very far, and can be seen both north and south of the inlet. The edges are churned up and blurred, and there are many layers fanning out.
I share to document. I share in hope of eventual change, and I share to inspire the so many people who are causing change, change, that one day we will see in a better water future.
Thank you to my husband Ed for piloting, and to passenger, and photographer, Matt Coppeletta.
All photos taken of the St Lucie Inlet area on 10-6-17 by Ed Lippisch and Matt Coppeletta. Discoloration of water is caused primarily by discharges from Lake Okeechobee but also from canals C-23, C-24, C-25 and area runoff.
“Right now billions of gallons of fertilizer, sewage, and legacy pollution from Lake Okeechobee are spewing into the St. Lucie River, carrying a new threat of toxic algae. Water managers may say Irma left them no choice, but of course that’s a half-truth…”
Documentation of primary and secondary plumes at St Lucie Inlet caused predominantly from human directed ACOE/SFWMD discharges post Irma and other from Lake Okeechobee & canals C-44, C-23, C-24, C-25. 10am, September 30, 2017. Primary plume out 3 miles; secondary 3 1/2 and not quite south to Peck’s Lake. We must continue to #ReplumbFlorida #forthefuture #forthewildlife #forthekidz #fortheeconomy for our #indianriverlagoon JTL/EL
As the possibility of a direct hit from Hurricane Irma approaches, I can’t help but reflect.
Looking back, we see that it was the severe flooding and the hurricane season of 1947 that led Florida and the U.S. Government down the track to where we are today through the creation of the Florida Central and South Florida Flood Project, (CSFP).
In 1947, during the United States’ post World War II boom, Florida had a very active and destructive hurricane season. This slightly edited excerpt from the ACOE’s book River of Interest does a good job giving a short overview of that year:
“…Rain began falling on the Everglades in large amounts. On 1 March, a storm dropped six inches of rain, while April and May also saw above average totals. The situation became severe in the summer…
As September approached and the rains continued, the ground in the Everglades became waterlogged and lake levels reached dangerous heights. Then, on 17 September, a hurricane hit Florida on the southwest coast, passing Lake Okeechobee on the west and dumping large amounts of rain on the upper Everglades, flooding most of the agricultural land south of Lake Okeechobee.
George Wedgworth, who would later become president of the Sugar Cane Growers Cooperative of Florida and whose parents were vegetable growers in the Everglades, related that his mother called him during the storm and told him, “ this is the last call I’ll make from this telephone because I’m leaving. . . . “We’ve got an inch or two of water over our oak floors and they’re taking me out on a row boat.”
Such conditions were prevalent throughout the region. Before the area had a chance to recover from the devastation, another hurricane developed, moving into South Florida and the Atlantic Ocean by way of Fort Lauderdale. Coastal cities received rain in large quantities, including six inches in two hours at Hialeah and nearly 15 inches at Fort Lauderdale in less than 24 hours.
The Everglades Drainage District kept its drainage canals open to discharge to the ocean as much of the floodwater in the agricultural area as it could, exacerbating coastal flooding. East coast residents charged the District with endangering their lives in order to please ag- ricultural interests, but this was vehemently denied…
Whoever was to blame, the hurricanes had devastating effects. Although the levee around Lake Okeechobee held, preventing the large numbers of deaths that occurred in 1926 and 1928, over 2,000 square miles of land south of the lake was covered by, in the words of U.S. Senator Spessard Holland, “an endless sheet of water anywhere from 6 to 7 feet deep down to a lesser depth.” The Corps estimated that the storms caused $59 million in property damage throughout southern Florida, but Holland believed that the agency had “under- stated the actual figures.” The destruction shocked citizens of South Florida, both in the upper Everglades and in the coastal cities, and they demanded that something be done.”
Well, what was done was the Central and South Florida Flood Project.
Key Florida politicians, and the public demanded the Federal Government assist, and as both the resources and will were present, the project was authorized in 1948 with massive additional components making way not only for flood protection, but for even more agriculture and development. In Martin County and St Lucie County this happened by the controversial building of canals C-23, C-24, C-25 and “improving” the infamous C-44 canal that connects to Lake Okeechobee. This construction was basically the nail in the coffin for the St Lucie River and Southern Indian River Lagoon.
But before the death of the environment was clear, the Corps developed a plan that would include 1,000 miles of levees, 720 miles of canals, and almost 200 water control structures. Flooding in coastal cities and in the agricultural lands south of Lake Okeechobee would be minimized and more controllable.
Yes, a goal of the program was to provide conservation areas for water storage, protecting fish and wildlife habitat. Although water conservation areas were constructed, conservation of wildlife did not work out so well, and has caused extreme habitat degradation of the Everglades system, Lake Okeechobee, the southern and northern estuaries, the Kissimmee chain of lakes, and Florida Bay. Nonetheless, this project made possible for over five million people to now live and work in the 18,000 square mile area that extends from south of Orlando to Florida Bay “protected from flooding” but in 2017 living with serious water quality issues.
With problems apparent, in 1992 the Central and South Florida Project was “re-studied” and we continue to work on that today both for people and for wildlife…
Irma many be the system’s greatest test yet…
Yesterday’s Army Corp of Engineer Periodic Scientist Call was focused on saving people’s lives and safety. After the built-system was discussed, Mr Tyler Beck of the Florida Wildlife Commission, and Mr Steve Schubert of the U.S. Fish and Wildlife Service reported on the endangered Everglades Snail Kites and their nests at Lake Okeechobee. Like most birds, pairs mate for life. There are presently fifty-five active nests, thirty-three in incubation, and twenty-three with baby chicks…
In the coming days, as the waters rise on Lake Okeechobee, and the winds scream through an empty void that was once a cathedral of colossal cypress trees, Mother Nature will again change the lives of Florida’s wildlife and its people, just as she did in 1947. Perhaps this time, she will give us vision for a future where nature and humankind can live in greater harmony…
On Halloween eve, October 30th 1979, the southwest side of the dike embankment at Florida Power & Light Company’s Martin Plant suddenly, and without warning failed catastrophically.
It was the dead of night and certainly the creatures of the nearby Barley Barber Swamp sensed more than their human masters. No person saw the incident. There were no cameras, no guards, no witnesses. It was the 1970s.
We can imagine, though, even though the final report said “not,” that for months sands had been slipping, eroding underground, perhaps led by connection to the old borrow pits dug for the railroad that came through in the 1920s.
My brother Todd’s latest spectacular time capsule flight takes us through this fateful night that by the time Halloween arrived, derailed a southbound train. The conductor reported the incident to his superiors as a “flash flood.” It was eventually realized that this flash flood was part of something much larger in scope!
Even if you know the story, the numbers are staggering…
As Todd notes, when the dike let loose, 100,000 cfs of water (cubic feet per second) blew into L-65, the canal on the edge of the FPL reservoir, and into the C-44 canal connected to the reservoir at S-53. The biggest numbers we hear these days in cfs is about 5000.
Facing west, a wave surged over the sugarcane fields and overtop US 441, traveling north seven miles in the rim canal. S-308 at Port Mayaca flowed backwards, and 4000 cfs entered Lake Okeechobee.
The finally alerted ACOE maxed S-80 at St Lucie Locks and Dam at 15,800 cfs, (over twice the highest amount of the Lost Summer of 2013 at 5700+/-). Crazy! Todd says the max for S-80 into the St Lucie River is 16,900 cfs. Not too far off were they.
Of course, these peaks would have only been for a few hours, but nonetheless, as is often the case, these kind of numbers mean “instant death for the St Lucie.”
This FPL event traveled much further north than the C-44 canal though; the last paragraph of the SFWMD 1980 report’s “failure section” notes:
“The Rim Canal reached a peak the next day (November 1) at the north end of the basin, 17 miles from the St. Lucie Canal. The flood was contained at this northerly point by the Nubbin Slough Tieback Levee along Canal 59. The maximum area flooded, was about 14,100 acres.”
What a story!
Well, it’s only history, right? But then history has a strange way of repeating itself in one form or another doesn’t it?
It is a journey the state, federal, and local agencies don’t always wish to take–a journey to face the numbers of our watershed…
Today, Dr Gary Goforth (http://garygoforth.net) shares his most recent report, “Water Quality Assessment of the St Lucie River Watershed, For Water Year 2017, DRAFT.”
Mind you, for non-scientist people like myself, a “water year” is reported from May of one year, through April the next year, as opposed to a calendar year.
The full report is linked at the bottom of the post and contains numerous helpful charts. I have just included the key findings below.
Dr Goforth wanted to get the draft assessment out before the Florida Department of Environmental Protection’s Basin Management Action Plan workshop scheduled for this Friday Aug. 25th at 10:00 am at Martin County Building Permits Office, 900 Southeast Ruhnke Street, Stuart, FL 34994, Conference Rooms A & B because this is where the rubber hits the road!

Water Quality Assessment of the St. Lucie River Watershed –Water Year 2017 – DRAFT Gary Goforth, P.E., Ph.D.
Quis custodiet ipsos custodes? (Who watches the Watchers?)
1. Over the last water year (May 2016 – April 2017), the surface water entering the St. Lucie River and Estuary (SLRE) in general was of poor water quality. The best water quality entering the SLRE was from the highly urbanized Tidal Basins. The largest source of phosphorus, nitrogen and sediment pollution to the SLRE was Lake Okeechobee discharges. The C-44 Canal Basin contributed poor water quality, and was the only basin demonstrating a worsening in water quality over the last ten years.
2. It was estimated that stormwater runoff from agricultural land use contributed more flow and nutrient pollution than any other land use, even contributing more flow than Lake Okeechobee discharges.
3. The annual Basin Management Action Plan (BMAP) progress reports produced by the Florida Department of Environmental Protection continue to indicate water quality conditions in the tributaries of the SLRE are better than they actually are. Examples of flaws in the BMAP assessment process include the omission of Lake Okeechobee pollution loads, the use of simulated data instead of observed data, the inability to account for hydrologic variability, and the inability to assess individually each of the major basins contributing to the SLRE.
4. An alternative to the assessment approach presented in the BMAP progress reports was developed and used to evaluate water quality conditions of major inflows to the SLRE and to assess progress towards achieving the Total Maximum Daily Load (TMDL) load reduction goals. This alternative approach uses observed data, includes Lake discharges, accounts for hydrologic variability, and is applied to each of the major basins contributing pollution loads to the SLRE. For WY2017, observed nitrogen loads to the SLRE exceeded the Phase 1 BMAP target loads (adjusted for hydrologic variability) by 77 percent. Observed phosphorus loads exceeded the Phase 1 BMAP target loads (adjusted for hydrologic variability) by 53 percent.
5. The largest single source of total nitrogen, total phosphorus and sediment load to the SLRE was Lake Okeechobee discharges. In addition, total phosphorus concentrations in Lake Okeechobee discharges to the SLRE remained almost four times the lake’s TMDL in-lake target concentration of 40 parts per billion (ppb). In 2017, the South Florida Water Management District (SFWMD) reported that phosphorus loading to the lake from surrounding watersheds was almost 5 times the Lake’s TMDL of 105 metric tons, yet staff acknowledged the agency does not enforce permits that set numeric limits on phosphorus discharges to the lake (SFWMD 2016, SFWMD 2017). Unfortunately, despite the continued and well-publicized pollution of the lake, the Florida legislature in 2016 enacted a water bill that pushed back deadlines for achieving the lake’s TMDL by decades (Ch. 2016-1).
6. The best water quality entering the SLRE during WY2017 was observed in the highly urbanized Tidal Basins, with concentrations of 97 ppb and 819 ppb for TP and TN, respectively. Each of the remaining source basins, except the C-44 Canal Basin, exhibited a slight improvement in nutrient levels compared to their base periods, however, collectively these WY2017 loads did not achieve the alternative BMAP Phase 1 load target (Figures ES-1 and ES-2). The C-23 and Tidal Basins met the alternative BMAP Phase 1 target for TP, while the C-23, C-24 and Tidal Basins met the alternative BMAP Phase 1 target for TN. The predominantly agricultural C-44 Canal Basin exhibited poor nutrient conditions, and in fact, continued a trend of deteriorating nutrient conditions compared to its 1996-2005 base period. As a whole, the water quality entering the SLRE remains poor, although a slight improvement over the 1996-2005 period was observed.
The video I am sharing today was filmed by the late Dr. Dale Hipson. Born and raised in Stuart, Dr Hipson was an avid wildlife lover, and very involved at the Stuart Heritage Museum. http://www.stuartheritagemuseum.com
Through the help of my mother, Dale’s family, and the community, I share one of Dr Hipson’s most famous videos from 2006 filming what seems to be hundreds of alligators marching across Powerline Road in the Dupuis Wildlife Area. I recall asking Dr Hipson why they were all crossing the road. “They are seeking more water,” he said, “levels change abruptly all the time.”
In the video, Dr Hipson and Shirley Corley’s “amazements” can be heard in the background. The video is quite delightful, even funny at times, and deserves to be reintroduced to the public. I know you will enjoy it.
The fact that Lake Okeechobee, the St Lucie River, and other water bodies of our state are in such poor condition puts the state of Florida “between a rock and a hard place.” After all, for centuries just saying the word “Florida” conjured up visions paradise…
Cyanobacteria, that often becomes “toxic algae,” is bad for business. In fact, perhaps nothing is worse for business. It is also bad for people’s health. Hmm? How does the state report toxic algae and fulfill their responsibility for safety without scaring people away? And without hurting business?
The answer is of course that “you really can’t…” But you can be honest and take leadership. You can turn a bad situation into a good one, because after all, a very powerful force of human nature is a common enemy.
Cyanobacteria, toxic algae, is our common enemy. For ALL of us.
The state has known that Lake Okeechobee has been eutrophic (prone to algae blooms) since at least the 1960s–the time of my birth. Early documentation from the state Geological Societies and Water Management Districts clearly documented the over nutrification of the lake, due to agriculture and development’s run-off exacerbated by channelization of rivers, lakes, the draining of lands, later the spreading of bio-solids (treated human waste) on fields, and a population explosion.
It is time to start diligently approaching the reporting of algae blooms and tracking their sources. There is a lot of area to cover; we can’t just test from the side of the road. Algae is living and changing and morphing every second. It is worth the investment to monitor it for what it is, an enemy. 24 hours a day…
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.”
*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.
I wanted to personally thank the South Florida Water Management District for their awesome new website “Everglades Agricultural Area Reservoir Project, A Timeline Toward More Water Storage South of Lake Okeechobee” that tracks Senate Bill 10 and the EAA Reservoir’s progress. I saw many people Tweet and post on this wonderful new tool, and wanted to share also and say THANK YOU!
Note below from District, what a nice gesture!
Hello, I’m not sure we have ever been formally introduced. My name is Jerry Eisenband and I’m the Comms Director at the SFWMD.
I was on your website the other day and saw this posting about SFWMD deadlines in relation to the EAA Reservoir.
I wanted to reach out and make sure you saw our latest and greatest webpage dedicated to this exact topic. Our goal is to keep the public informed.
I hope you like this website and encourage your followers to utilize it. If you can give us any help to promote it, we would be extremely grateful.
West Palm Beach, FL – The South Florida Water Management District (SFWMD) today launched a new webpage, featuring an interactive map and milestone tracker to allow the public to follow the progress of the Everglades Agricultural Area Reservoir south of Lake Okeechobee.
“This project was approved by the Florida Legislature and signed into law by Gov. Rick Scott, as part of an effort to reduce harmful Lake Okeechobee discharges to the Caloosahatchee and St. Lucie estuaries,” said SFWMD Governing Board Chairman Dan O’Keefe. “This new web page allows citizens to see how their tax dollars are being spent on this project, as well as track the progress of this reservoir.”
The Water Resources Law of 2017 — Senate Bill 10 — calls for SFWMD to construct a reservoir that can hold 240,000 acre-feet of water on about 18,000 acres of state-owned land in the Everglades Agricultural Area (EAA) south of the lake. This property was originally purchased with the intention of building a shallow Flow Equalization Basin (FEB), which would have been known as the A-2 FEB.
The project was included in the Comprehensive Everglades Restoration Plan, as well as Central Everglades Planning Project to improve the conveyance of water south from the lake to Everglades National Park. Instead, the land will now be used to build the much deeper 240,000-acre foot reservoir. The EAA Reservoir is intended to help reduce damaging estuary discharges from the lake.
The web page displays to the public where the reservoir will be located, what steps required by the Legislature have already been completed and what key points remain. To date, SFWMD has identified the approximately 3,200 acres of land it owns (currently leasing to private entities) that would be used for the project and about 500 acres of privately owned land that would need to be acquired. SFWMD has already contacted the private landowners to express interest in acquiring their property.
By July 1, SFWMD will take the next step by sending a letter to the U.S. Army Corps of Engineers requesting that the Corps develop with SFWMD a “Post Authorization Change Report” to the project for approval by the U.S. Congress. This is necessary since the land was originally slated to be used as part of the Congressionally-approved Central Everglades Planning Project.
In recent years we along the St Lucie River/Indian River Lagoon have been screaming because the ACOE and SFWMD have been discharging water from Lake Okeechobee and the C-44 basin into our waterways causing destructive toxic algae blooms and other issues to our area …
This year some are screaming because C-44 basin runoff water in southern Martin County is being pumped back into Lake Okeechobee. Yes, C-44 is “running backwards.” It’s a crazy world here in South Florida even through the water managers are working hard at “getting the water right…”
So two odd things are going on right now. First, water is being sent into Lake O from the C-44 canal as we were in a long-time drought, and also, now, water is being back-pumped into the lake from the south to help alleviate flooding in the Water Conservation Areas— as it has rained so much recently “down there.” This whole situation is exacerbated because the EAA, in the middle, “is kept dry to protect the property of the agricultural industry and safety of communities south of the dike.”
The graph and short write-up below are from friend and engineer Dr Gary Goforth. The graph “shows” the C-44 basin runoff (see image above) being sent to Lake Okeechobee in 2017 compared to other years since 1980 (other than ’81) “is at 100%.”
I have also included some articles and images on the other “back into Lake O” subject. Back-pumping was made illegal in the 1990s, but is allowed under certain circumstances such as endangering communities and agriculture in the EAA, and danger to wildlife in the conservation areas due to flooding…All of this is “back-pumping” not good for the health of the lake. In all cases, it is helping one thing while hurting another…
One day we will have to truly get the water right. Images below may help explain things.
ISSUE OF BACK-PUMPING:
ISSUE OF C-44 CANAL BASIN WATER BEING SENT INTO LAKE O RAHTER THAN TO SLR:
” For the period 1980-2016, about 32% of the C-44 Basin runoff was sent to the Lake, while 68% was sent to the St. Lucie River and Estuary. Historically (i.e., before 1923) virtually none of the C-44 Basin runoff went to the St. Lucie River and Estuary: some went to the Lake, some went to the Loxahatchee River and some went north to the St. John’s River. So far in 2017, virtually all of the basin runoff has been sent to the Lake.”
The following is a handout Mark Perry of Florida Oceanographic passed out yesterday at the Rivers Coalition meeting. It is created by John Ullman of the Florida Sierra Club and gives clear presentation on what is necessary for the EAA Reservoir and SB10’s success. I am reprinting here as a resource and reference. Getting the legislation passed for Senate Bil 10 was just the beginning. As we know, for the reservoir to come to fruition we must be diligent over the coming years.
Notice the July 1st, 2017 deadline for the SFWMD to”request that the US Army Corps jointly develop a post-authorization change report for the Central Everglades Planning Project to revise the A-2 parcel element of the project.”
Relationships with the District continue to be strained; a nice phone call or email to Executive Director Peter Antonacci or board member would prove helpful. We must rebuild relationships for future success. We all do have a common goal, clean water for Florida.
SIERRA CLUB, FLORIDA’S SB10 Blog-by John Ullman
SB10, Important Deadlines:
By July 1, 2017 SFWMD must request that the US Army Corps jointly develop a post-authorization change report for the Central Everglades Planning Project to revise the A-2 parcel element of the project.
By July 31, 2017, SFWMD must contact the lessors and landowners of 3,200 acres of state-owned land and 500 acres of privately-owned land just west of the A-2 parcel. SFWMD must express interest in acquiring this land through purchase, exchange, or terminating leases.
If the US Army Corps agrees to begin developing the post-authorization report, work on the report must begin by August 1, 2017.
SFWMD must report the status of the post-authorization change report to Fla Legislature by January 9, 2018.
SFWMD and Corps must submit the post-authorization change report to Congress by October 1, 2018.*
The House passed the measure with a 99-19 vote; the Senate passed it 33-0.
The Governor signed SB 10 into law on May 9, 2017
Details of SB 10:
• Accelerates the state’s 20-year goal of storing water south of Lake Okeechobee.
• Requires SFWMD to develop a project plan for an Everglades Agricultural Area (EAA) Reservoir that provides at least 240,000 acre-feet (about 78 billion gallons) of water storage by utilizing the A-2 parcel (14,000 acres of state-owned land), land swaps, early termination of leases, and land acquisition.
• Provides for at least two-thirds of the water storage capacity of the Comprehensive Everglades Restoration Plan (CERP) Component G.
• Allows the A-1 parcel to remain a Flow Equalization Basin (FEB) as provided for in the Central Everglades Planning Project (CEPP), or to be utilized for the EAA Reservoir if SFWMD can provide for at least 360,000 acre-feet of water storage.
• Requires SFWMD to include increased canal conveyance improvements, if needed, and features to meet water quality standards in the EAA Reservoir project.
• Provides deadlines for submitting the plan to Congress as a post-authorization change report, which will seek approval of the use of the A-2 parcel in a different manner than was authorized in CEPP.
• If the Corps has not approved the post-authorization change report and submitted it to Congress by October 1, 2018 or the post-authorization change report is not approved by Congress by December 31, 2019, SFWMD must request the Corps to develop a project implementation report for the EAA Reservoir Project located somewhere else.
• Prohibits the use of eminent domain to obtain privately held land.
• Provides for termination of the U.S. Sugar option agreement prior to the October 2020 expiration date if the post-authorization change report receives congressional approval or SFWMD certifies to the Board of Trustees of the Internal Improvement Trust Fund, the President of the Senate, and the Speaker of the House that acquisition of the land necessary for the EAA reservoir project has been completed.
• Authorizes the use of Florida Forever bonds in an amount of up to $800 million for the costs of land acquisition, planning and construction of the EAA reservoir project.
• Appropriates $30 million from the Land Acquisition Trust Fund (LATF) to the Everglades Trust Fund, in the 2017-18 fiscal year, for the purposes of acquiring land or negotiating leases to implement or for planning or construction of the Everglades Agricultural Area reservoir project.
• Appropriates $3 million from the LATF to the Everglades Trust Fund in the 2017-18 fiscal year for the development of the CEPP post-authorization change report.
• Amends the LATF distribution to include $64 million of additional funding for the EAA reservoir project.
• Appropriates $30 million from the General Revenue Trust Fund to the Water Protection and Sustainability Program Trust Fund to provide a loan for implementation of Phase I of the C-51 reservoir project.
• Appropriates $1 million from the LATF to the Everglades Trust Fund in the 2017-18 fiscal year for the purpose of negotiating Phase II of the C-51 reservoir and provides the LATF as a potential funding source for the implementation of Phase II of the C-51 reservoir.
• Creates the water storage facility revolving loan fund and requires the Department of Environmental Protection (DEP) to adopt rules for its implementation.
• Creates the Everglades Restoration Agricultural Community Employment Training Program within the Department of Economic Opportunity (DEO) to provide grants to stimulate and support training and employment programs that seek to re-train and employ displaced agricultural workers.
• Requires SFWMD to give preferential hiring treatment to displaced agricultural workers, consistent with their qualifications and abilities, for construction and operation of the EAA reservoir project.
• Terminates the inmate labor work program on state-owned lands in the EAA.
The post-authorization change report must be approved by Congress by December 1, 2019.*
*If these two deadlines are not met (and no extension is granted), then the SFWMD must request that the Corps initiate the planning for the EAA Reservoir project that will result in a new Project Implementation Report (PIR) and may continue to build CEPP components as planned in the 2014 PIR.
My brother, Todd, wrote to me on June 8th noting that the C-44 canal was flowing westwards into Lake Okeechobee rather than dumping eastwards into the St Lucie as is standard operating procedure after a big rain…
Yes this canal, as most of the others, can “flow” in either direction, seemly “backwards.”
So how can this happen? This backwards flow?
Dr Gary Goforth says the following:
“Yes this is normal operations; generally when the Lake level is below 14 ft the Corps leaves the locks at S-308 wide open which allows any local runoff to flow into the lake.”
Another way Lake Okeechobee can receive water in an unusual way is if the water is pumped into it–back pumped. This has recently been done from the EAA. Back pumping into Lake O has been outlawed, but it is allowed if communities or farmland would flood.
According to an exchange yesterday on Facebook, with Audubon’s Dr Paul Grey:
“St Lucie (C-44) backflows are just one of many southern inflows now, S-2 is backpumping, three other southern outlets are flowing backward into the low lake (L-8, S354, S-352) the Caloosahatchee was backflowing but appears equalized today. More water is flowing into the lake from downstream areas than upstream right now. Not the end of the world but not desirable either, it is very polluted water. http://w3.saj.usace.army.mil/h2o/reports/r-oke.html “
When I asked Dr Grey if this was being done to gather water in the lake as we’ve recently been in a drought, or to keep the farmlands in the EAA and surrounding areas dry, this was his response:
“Both, they want to fill the lake this summer, and so do I, in concept, but much of this backpumping and flowing is because the farmers have been pumping water so rapdily off their own lands they have made the canals too deep, and risk fooding the communities. And rather than tell the farmers the canal its too deep and they have to modererate their pumping, the SFWMD backpumps/flow it to the lake.”
In any case, when I visited yesterday during my trip to Belle Glade, S-308 was closed at Port Mayaca and no more water was entering Lake O from C-44. I’m not sure about S-2.
The water looks dark and full of sediment. The once beautiful beach is full of gritty rocks. Maybe the lake is healthy in the shallows south, near the islands, but by Port Mayaca it looks terrible. Algae has been reported by S-308 a few weeks ago according to a report from Martin County at the River’s Coalition meeting. But thankfully there is not algae reported in C-44 right now.
We have really made a mess of it. For our rivers and for Lake Okeechobee, the reservoir must be built and we must continue to advocate for sending cleaned water south and re -plumb this outdated system. Forward flow or backwards flow, just say NO.
Todd Thurlow notes 6-8-17
Interesting note: if this data is correct, C-44 has poured 10.7 billion gallons (aka 13.82 Stuart Feet) of water into Lake Okeechobee in the last three days. With all the recent “local” runoff into the canal, they have opened S-308, sending the water west to the Lake to help get the low lake level up.
48.5 million gallons passed through S-80 to the St. Lucie on June 5th…

Today I am sharing a report that came out only yesterday and is spreading through social media and news channels like ~ toxic algae…
“Tainted Waters, Threats to Public Health, and People’s Right to Know” is written by award-winning journalist and ACLU investigative reporter, John Lantigua.
After being contacted, Mr Lantigua approached me and many others months ago, traveling and interviewing numerous stakeholders from various backgrounds. He was a consummate professional with an air that only an experienced, savvy, and hard-hitting journalist can attain. I will never forget being interviewed by him at a diner in Belle Glade and saying to myself: “Holy cow, this is the real deal…”
In today’s TCPalm article by Tyler Treadway, Mr Lantigua states: “We don’t typically focus on environmental concerns but getting timely and trustworthy information about a public health issue is a civil right…”
Thank you Mr Lantigua for recognizing the “lack of urgency and transparency” on the part of the state of Florida in reporting information about the 2016 Toxic Algae Crisis caused by the Army Corp of Engineers and South Florida Water Management Districts’ releases of tainted waters from Lake Okeechobee into our St Lucie River/Indian River Lagoon.
ACCESS REPORT “Tainted Waters, Threats to Public Health, and the People’s Right to Know,”HERE:
This photo is on page 23 of my mother’s book Historic Jensen and Eden on Florida’s Indian River. The insert reads:
“This photograph of the Seymour Gideon property was made after 1948 when Arthur Ruhnke started taking photographs locally, and before the August 26th 1949 hurricane that destroyed the fish houses. A trail leads to the ridge called “Mt. Washington” (Killer Hill, Skyline Drive today) by the pioneers. The watery expanses of the Jensen Savannas are in the distance. Notice the clear water and the abundance of river grass.” (Thurlow/Ruhnke Collection)
It is a beautiful photograph….isn’t it? Certainly after the Hurricane of ’49 hit the seagrasses of Jensen in the Indian River Lagoon were impacted too!
~Wind gusts reached 160 mph (260 km/h) at Stuart.
~Stuart (Jensen) experienced the most severe damage from the storm in south Florida; hundreds of homes, apartment buildings, stores, and warehouse buildings lost roofs and windows. Interior furnishings were blown through broken glass into the streets.
When hurricanes Frances and Jeanne hit within three weeks apart in 2004, entering both times at my hometown of Sewall’s Point, there was reported loss not only of property, but also of seagrasses in the Indian River Lagoon. Seagrass is very slow to recover…
As some locations of the grasses were experiencing recovery, they died back again due to the extreme discharges and toxic algae blooms in 2013 and 2016 ~linked to Lake Okeechobee, and canals C-44, as well as C-23, C-24 and C-25.
The South Florida Water Management District reports periodically on not overall numbers but rather “patch dynamics” at certain locations of the lagoon. (For Martin County: Boy Scout Island and Willoughby Creek.) I feel this is limited. The best way to see seagrass bed coverage is from the air. I am hoping in the future there will be money in the budget or the District could coordinate with local pilot for aerial seagrass surveys. Another way to approach this is though Google Earth mapping/aerials, and my brother Todd Thurlow and Mark Perry of Florida Oceanographic are working on this now.
Hurricanes, discharges, fertilizer from our yards…Seagrasses are as important as property as they are the nurseries of the oceans and keep the lagoon “living.” Look at the aerials below to see the losses, so that we may be inspired to work for and better document a recovery.
At the recent Bullsugar “Fund the Fight” event, Captain Mike Connor introduced me to Montana based, award-winning fishing and hunting journalist, Hal Herring. I looked Hal straight in the eye, shook his strong hand and said, “It’s so nice to meet you Mr Herrington.” He smiled, eyes sparkling, and replied, “Herring mam. Like the fish.”
Fly Life Magazine writes: “Herring, one of the leading outdoor writers of our time, co-manages the Conservationist Blog for Field & Stream, is the author of several books and is a regular contributor to numerous other well-known outdoor news outlets including High Country News, Montana’s Bully Pulpit Blog and the Nature Conservancy magazine.”
To say the least, I felt honored to be chosen as a tour guide for Hal Herring as my husband and Mike Connor arranged an aerial journey for the visiting journalist. After researching Hal, checking out his website, and reading his article on the Clean Water Act, I knew I was dealing with a gifted journalist. What a great person to have learn about the problems of our St Lucie River!
We prepared the Baron for Saturday. My husband Ed invited friend and fellow fisherman Dr Dan Velinsky. The flight stared with a rough take off. I steadied myself. “Please don’t let me puke Lord…” As Ed gained altitude, things settled down and we were on our way…
After taking off from Witham Field in Stuart, we followed the dreadful C-44 canal west to Lake Okeechobee; diverting north at the C-44 Reservoir under construction in Indiantown; traveled over the FPL cooling pond and S-308, the opening to C-44 and the St Lucie River at Port Mayaca. Next we followed Lake Okeechobee’s east side south to Pahokee, and then Belle Glade in the Sugarland of the EAA; here we followed the North New River Canal and Highway 27 south to the lands spoken about so much lately, A-1 and A-2 and surrounding area of the Tailman property where Senate Presidient Joe Negron’s recently negociated deeper reservoir will be constructed if all goes well; then we flew over the Storm Water Treatment Areas, Water Conservation Areas, and headed home east over the houses of Broward County inside the Everglades. Last over West Palm Beach, Jupiter, north along the Indian River Lagoon and then back to the St Lucie Inlet. Everywhere the landscape was altered. No wonder the water is such a mess…
I explained the history, Dan told fish stories, Ed ducked in and out of clouds. All the while, Hal Herring took notes on a yellow legal pad with calmness and confidence. Nothing surprised him; he was a quick study in spite of all the variables. He was so well read, not speaking often but when he did, like a prophet of sorts. He spoke about this strange time of history, the time we are living in, when humans have overrun the natural landscape. He spoke about mankind being obsessed with transcending the limits of the natural world…and the control of nature…but for Hal there was no anger or disbelief, just wisdom. In his biography, he says it best:
“My passions as a writer and storyteller lie where they always have – in exploring humankind’s evolving relationship to the natural world, and all the failures, successes and deep tensions inherent in that relationship…”
In the Everglades region, Hal may just have hit the jackpot!
Today I am again honored to feature the writing of Professor Geoff Norris. This most recent work is a tremendous achievement of time, research, and puzzle piecing. Professor Norris’ past shared articles “Blue Green Algal Blooms in the Lakes, Rivers, and Marine Waters of South Florida Surrounding Lake Okeechobee,” and “Sugarcane and Indians” were extremely popular with many of my readers. Professor Norris has a way of communicating complex topics in an easy and interesting way so that everyone can understand and make the connections. In the 1960s Professor Norris lived and worked as a petroleum exploration geologist in Tulsa, Oklahoma. Subsequently, he spent 40 years at the University of Toronto teaching and performing research in geology. A geologist by training, Professor Norris has a specialized knowledge of fossil algae, their ecology, morphology, and distribution. He has published hundreds of scientific papers on fossil algae and related topics…I encourage you to contact him by email with any questions at firstname.lastname@example.org
Thank you Professor Norris. “Together we will create a “better water future!”
Lake Okeechobee blue-green bacterial blooms in Florida: lessons from Lake Erie
In the following article, I have attempted to summarize some of the voluminous literature on Lake Erie and its problem blue-green blooms, and how this might help to understand similar events in Lake Okeechobee. I have included URL web addresses for some of the topics, which can be used to access further information.
Although the blooms are often referred to as blue-green algae, this is quite inaccurate and I can see no further point in perpetuating this misnomer. The blooms are largely or entirely composed of Cyanobacteria, or blue-green bacteria as I have chosen to call them for this article. This is not just for precision and to point up their lack of a nucleus and other organelles in each cell, but serves to underline how these organisms earn a living and perpetuate themselves that is quite different compared to nucleated organisms, the latter including algae, fungi, all green plants, and all animals. This difference is really important.
The topic is vast and my review barely scratches the surface – it’s not meant to, because I am not an expert and am still trying to understand the vast complexity of blue-green bacterial bloom formation. I have tried to unravel and clarify some of the science and scientific investigations that have been important for me, and have used these as examples of the work that is going on or has led to current advances. For every paper I have cited, however, there could be tens or hundreds more that haven’t been consulted or mentioned. I apologize in advance to those many talented scientists that I haven’t mentioned or that I am simply unaware of.
I used to live in Hamilton, Ontario, a prosperous city with thriving iron and steel mills, other manufacturing industries, an excellent university and a great football team, a sort of Pittsburg of the North. It sits on the shores of Lake Ontario on a sliver of land – the Niagara Peninsula – that separates Lake Erie from Lake Ontario. In the early summer after the ice had melted, many of the locals in the mid-1900s would take advantage of the beaches along Lake Ontario to sun themselves and wait until the water was warm enough to swim in. However, you could get a head start on summer by taking a short drive south (less than an hour) to the beaches along Lake Erie where the water was warmer earlier in the summer, and resorts and tourism thrived. Fish were abundant and the lake was very productive for commercial fishing and equally attractive for sport fishing. The beaches were superb for tourism and sun lovers. Lake Erie is large but shallow (average depth about 60ft) and so a baby on a Great Lakes scale from a volumetric point of view (most of the Great Lakes are hundreds of feet deep, the deepest being Superior at more than 1300 ft maximum depth). However, Lake Erie’s smaller volume and shallow waters helped it to warm up quickly in the spring and summer.
The Dead Sea of North America
Then something happened to Lake Erie, starting in the 1960s. The water of Lake Erie became murky and discolored, mass fish kills led to piles of rotting marine life polluting the beaches, the tourists and anglers and sun worshippers stayed away in droves, the resorts closed down, the commercial fisheries were badly hit, and the economy suffered enormously. Algae were blamed but no one was quite sure why they had become so abundant – “eutrophication” was the buzzword of the time. Lake Erie was declared “dead”, which was quite inaccurate since it was swarming with life, but the wrong sort of life. The culprits polluting the environment were a mixture of true green algae (such as Cladophora) and so-called “blue green algae” (such as Microcystis and Aphanizomenon), which in truth are types of bacteria using chlorophyll and other pigments that allow them to live in sunlight (their technical name is Cyanobacteria –called blue-green bacteria in this article), and this is discussed in more detail in my previous blog: https://jacquithurlowlippisch.com/tag/dr-geoffrey-norris/). The plight of the Dead Sea of North America (as Lake Erie became known) was so notorious that one of Dr Seuss’s books for children – The Lorax (1971) – made reference to it in his famous style of doggerel:
You’re glumping the pond where the Humming-Fish hummed!
No more can they hum, for their gills are gummed.
So I’m sending them off. Oh, their future is dreary.
They’ll walk on their fins and get woefully weary
In search of some water that isn’t so smeary.
I hear things are just as bad up in Lake Erie.
Very fortunately the mystery of Lake Erie’s “death” was soon solved, thanks to a treaty between the U.S. and Canada dating back to the early 1900s that acknowledged the need to maintain water quality in the Great Lakes’ waters bordering the two countries.
By the middle of the 20th century this had morphed into the International Joint Commission for the Great Lakes. These international efforts were underpinned by government and university-based research in both the U.S. and Canada, which identified phosphorus entering the waters as a major contributor, particularly from agricultural fertilizers on the one hand and from domestic laundry detergents on the other. In 1972 the Great Lakes Water Quality Agreement (GLQWA) was signed between the United States and Canada, by Prime Minister Pierre Trudeau for Canada and President Richard Nixon for the United States. They loathed one another personally, but they knew what was the right thing to do for their countries.
Prime Minister Pierre Elliott Trudeau and President Richard Nixon signing the Agreement.
The Agreement emphasized the reduction of phosphorous entering lakes Erie and Ontario, and, in 1977, maximum levels for phosphorous were added to the Agreement. Also, phosphorus in laundry detergents was finally drastically reduced or banned. Coupled with the U.S. and Canadian Clean Water acts, the International Joint Commission did much to reduce the phosphorus levels in Lake Erie.
International Joint Commission (IJC): “More than a century of cooperation protecting shared waters. Canada and the United States each appoint three of the six IJC Commissioners, including one chair from each country. The two chairs serve concurrently.The Commissioners are appointed by the highest level of government in each country, but once appointed they do not represent the national governments; they operate at arm’s length.The Commissioners traditionally work by consensus to find solutions that are in the best interest of both countries. The Commissioners are supported by U.S. and Canadian Section offices in Washington, D.C. and Ottawa, Ontario.”
So everyone breathed a sigh of relief, phosphorus levels went down, farmers applied fertilizers to their fields differently, consumers chose phosphorus-free detergents, municipalities improved their storm water and sewage treatment facilities, the fish and other wildlife came back to Lake Erie, and Dr Seuss was persuaded to remove the last line in his poem. Further details can be found in a report by the National Wildlife Federation:
For almost 20 years, Lake Erie was not plagued by the blue-green bacteria problem, but other problems did emerge such as exotic zebra mussels that interfered with the distribution of elements important in nutrition, but they seemed at the time to be unrelated to bacterial infestations. Then starting in the mid-1990s, the blue-greens reappeared and became progressively worse leading to super-gigantic blooms that choked the western end of Lake Erie with green muck inches thick and hundred of square miles in extent. Dead zones – biological black holes – reappeared in the Lake as the rotting organic matter sucked the oxygen out of the water, promising certain death to animals that ventured in.
In the summer of 2011 the mother of all blue-green bacterial blooms exploded in Lake Erie, the bloom at its peak being more than 1900 square miles in extent. That is more than 50% greater than the entire state of Rhode Island, or 35% larger than Long Island, or more than six times larger than all of New York City’s five boroughs. This super-giant bloom had an estimated weight of 40,000 metric tons dry weight. The wet weights of algae and blue-green bacteria are generally at least 10 times the dry weight. So, this supergiant bloom had at least half a billion tons of blue-green bacteria living within it – a true monster.
MODIS (Moderate Resolution Imaging Spectroradiometer) satellite Image of Lake Erie on September 3, 2011, overlaid over map of Lake Erie tributaries. This image shows the bloom (in green) about 6 weeks after its initiation in the western basin. From Michalak et al, 2013.
These blooms had a devastating effect on the areas flanking the western end of Lake Erie – Ohio, Michigan, and Ontario – with large agricultural areas and several major cities and industrial towns. Toxins from the blue-green bacteria polluted the drinking water supplies of large cities, and potable water had to be trucked in for the residents.
The “greening” of Lake Erie has been documented by Prof. Tom Bridgeman of the University of Toledo in a presentation:
In his presentation Prof. Bridgman showed how increasing phosphorus in the lake water favored the blue-green bacteria and shut out the normal tiny floating plants (true algae), a situation that had culminated in the American Dead Sea catastrophe of the 1960s. The international agreement on phosphorus reduction in the Great Lakes was a huge success story for Lake Erie, but by the mid 1990s algal biomass was beginning to increase again (eutrophication was returning), and by the early 2000s blue green bacteria such as Microcystis were increasing ten-fold, as the reactive phosphorus in the lake waters increased beyond levels recorded in the 1970s.
What the heck was going on here? Everyone had played their part in reducing phosphorus run-off from agricultural lands, and the municipalities and citizens had cleaned up their act. So where was the phosphorus coming from? Well now the plot thickens.
Farming and Phosphorus
This time, the main problems are thought to be ones that governments have much less direct control over, according to a file posted by Emily Chung of the Canadian Broadcasting Corporation News (2014).
To some extent, they include the application of fertilizers to lawns and golf courses, growing expanses of pavement in urban areas that cause water to drain more quickly into waterways without being filtered by vegetation, and invasive zebra mussels that release extra nutrients into the water as they feed. But those aren’t thought to be the biggest cause.
“We think farming is the major culprit behind the current levels of phosphorus that’s in runoff and the phosphorus loads that are getting dumped into the western basin of Lake Erie,” said Dr. Glenn Benoy (senior water quality specialist and science adviser with the International Joint Commission in Ottawa).
Dr Glenn Benoy
So why is this? Well, there are several things going on. Firstly, corn production is at an all time high because of the push to increase alcohol biofuel production, and soybeans are being produced in gigantic quantities for use as animal feed, oil and protein for human consumption, plastics and biodiesel. Secondly, the introduction of no-till farming practice in the U.S. has led to increased run-off of fertilizer. Thirdly, there’s just not enough infrastructure to deliver in the spring the huge amounts of fertilizer that are required by the corn farmers. Prof. Ivan O’Halloran of Guelph University, Ontario and a specialist in soil fertility and nutrient use commented that the demand by corn farmers is such that there are simply not enough rail cars to satisfy the need. So companies offer discounts to farmers who are willing to apply fertilizer in the fall, which in turn leads to enhanced run-off of phosphorus during the winter storms.
Prof. Ivan O’Halloran
No-till Farming and Glyphosate
And then there is the matter of no-till farming. No-till farming (also called zero tillage or direct drilling) is a way of growing crops or pasture from year to year without disturbing the soil through tillage, and in current practice depends on the use of powerful herbicides such as glyphosate (Monsanto’s Roundup brand being the most popular formulation). Application of glyphosate kills weeds and other vegetation in preparation of the seedbed. Later in the year, another application of the herbicide is used to reduce weeds that might be harming the crop. However, this is only possible if the farmers use genetically modified seeds that are resistant to glyphosate – often referred to as Roundup Ready seeds. In 2014 in the U.S. 98% of soybeans and more than half of corn was Roundup Ready. Advocates of Roundup point out that glyphosate is a compound derived from phosphonic acid in which the phosphorus is strongly bonded to carbon and therefore is not available to plants, unlike fertilizer which contains phosphates (not phosphonates) which has phosphorus bonded less strongly to oxygen, and is therefore more readily available for uptake by plants (often referred to by the acronym DRP – dissolved reactive phosphorus).
Prof. Chris Spiese is a chemist at Ohio Northern University and he decided to test the contribution that glyphosate might make to the amount of dissolved reactive phosphorus running off of cultivated fields. He found that glyphosate acts on the soil to allow the phosphorus bonded to the soil (either being naturally present or due to fertilizer use) to be released by the chemical process known as desorption. He also found that soils richer in both iron oxides and iron hydroxides tend to release by desorption more phosphorus, as do soils that are more acidic. Overall, he calculated that glyphosate is responsible for releasing 20-25% of the dissolved reactive phosphorus in the Maumee watershed, a river discharging into the western end of Lake Erie. Prof. Spiese calculated that for every acre of Roundup Ready soybeans, one-third of a pound of phosphorus comes down the Maumee River. In 2010, according to the Ohio Soybean Council, 4.6 million acres were planted in soybeans, of which about 2 million acres of soybean fields drain into Lake Erie.
If Prof. Spiese’s calculation for the Maumee watershed hold true for all the soybean acreage in Ohio draining into Lake Erie, this would suggest that each year hundreds of tons of dissolved reactive phosphorus are entering the Lake from this source alone. And then there are the other states and provinces bordering Lake Erie that are also involved in soybean production: Ontario 2 million acres; Michigan 1.5 million acres; NW New York, 1/3 million acres; Pennsylvania 1/2 million acres. Of course, not all these agricultural lands drain into Lake Erie but these numbers give some idea of potential dissolved reactive phosphorus input related to soybean production alone.
The Monster Revisited
The super-giant blue-green bacterial bloom of 2011 in Lake Erie required a concerted response from the scientific community to understand just why this had happened. There was no doubt in scientists’ minds that dissolved reactive phosphorus as run-off from agricultural land was a major factor. But why should a super-giant bloom happen in 2011 and not in 2012 when the same agricultural land and its phosphorus run-off were still flanking the Lake and continued to be a constant factor? Something else was involved. So an elite team of scientists from universities, government laboratories, and industrial laboratories got together to investigate, headed up by Prof. Anna Michalak of Stanford University.
Prof. Anna Michalak
In 2013 this team of 29 scientists came up with their report, which was published in the prestigious Proceedings of the National Academy of Sciences.
The team concluded that long-term trends in agricultural practices (e.g. no-till farming) plus increased acreage under intense cultivation (notably soybeans and corn) led to a major pulse of phosphorus into Lake Erie during some unusually intense spring rainstorms in 2011. Then in the late spring and summer unusually quiet but warm weather conditions provided just the right conditions to seed, incubate and grow the bloom in the waters of Lake Erie. The team stated “If a scientifically guided management plan to mitigate these impacts is not implemented, we can therefore expect this [super-giant blue-green bacterial] bloom to be a harbinger of future blooms in Lake Erie.” – because unusual weather events, lower wind speeds, warmer waters, and higher rainfalls are becoming more common and can be expected in the future.
Glyphosate and Blue Green Bacteria
Recent work by scientists at Bowling Green State University has reported the presence of glyphosate in Lake Erie. It is evidently washing out of the no-till crop fields, and reaches a maximum in the summer months. Also it has been found in water treatment plants, peaking in the summer months. Prof. McKay and his colleagues raised the possibility in 2010 that the presence of glyphosate in Lake Erie together with phosphates from fertilizers tend to stimulate the growth of blue-green bacteria, whereas phosphates alone do not do this but favor diatoms, a normal algal component of Lake Erie. It seems that blue-green bacteria can utilize the phosphorus in the glyphosate, which was believed to be otherwise not normally bio-available. Many questions remain to be answered but the intense use of glyphosate in the area around Lake Erie demands rapid action in the very near future to establish just how much glyphosate is involved in blue-green bacterial blooms.
An even more disturbing piece of microbiological and genetic research was done by Prof. Victoria López-Rodas in Madrid together with other Spanish colleagues in 2007. They studied Microcystis, one of the bad boys of the blue-green bacteria family. They found that rare mutations during growth and division of cells could clone a glyphosate-resistant strain that could survive in glyphosate polluted waters. In other words, Microcystis has the potential to develop into a “superbug” unaffected by glyphosate. The odds of a mutation like this occurring were calculated to be a few times in 10 million by Prof. Lopez-Rodas’ team. That’s better than the odds for winning the Jackpot in the Florida Power Ball Lottery (1 in 292 million), but still not great. If you bought hundreds of millions of ticket in the lottery, you would have a good chance of winning at least once, perhaps several times (but at $2 a ticket you financial advisor might have some things to say to you about your investment strategy). However, given a little phosphorus and nitrogen, Microcystis can keep on dividing trillions and trillions of time to form blooms in warm water. With such astronomical numbers, a rare mutation becomes a virtual certainty at some point during cloning, and in the presence of an antibiotic such as glyphosate, a superbug is born.
So far the emphasis has been on phosphorus and how it is important in blue-green bacterial bloom formation. But nitrogen is also very important as a nutritional component for blue-greens and indeed for all life. Green plants need nitrogen to synthesize proteins and other important components in their cells. Although nitrogen is abundant in the atmosphere, it is an inert gas and simply unavailable as a nutrient for many green plants. It needs to be combined with hydrogen (as an ammonia compound) or with oxygen (as a nitrate compound) to be absorbed by the plant. These nitrogen compounds may be naturally occurring in soil, but in agricultural land they need to be added frequently as fertilizer for crops to thrive.
Blue-green bacteria have an advantage over green algae and other green plants because some blue-greens have the ability to synthesize nitrogen compounds directly from gaseous nitrogen – they are said to be able to “fix” the nitrogen. But some other blue-green bacteria are unable to fix the nitrogen and have to depend on another source. Microcystis is a case in point (the blue-green bacteria that are often dominant in the giant blooms in Lake Erie and Lake Okeechobee). Microcystis is highly dependant on a source of nitrogen to thrive. This can of course be provided by run-off from crop fertilizer, but it does not always explain the fluctuations of this and other blue-green bacteria that have or do not have nitrogen fixation ability in Lake Erie, in spite of the fact that the experts all agree that phosphorus – not nitrogen – is the principal limiting factor.
Lucas Beversdorf and colleagues at the University of Wisconsin decided in 2010 to try and solve the problem and improve predictability of toxic blue-green episodes in a beautifully designed and detailed study of Lake Mendota, Wisconsin a much smaller lake (15 square miles) than Lake Erie but about the same depth and with similar temperate seasonal weather patterns.
They found that Microcystis (blue-green non-nitrogen fixer) rode on the back of Aphanizomenon (blue-green nitrogen fixer) in a nutritional sense. Without the nitrogen fixer doing its work first in the spring, Microcystis as a non-nitrogen fixer could not attain dominance and pollute the water with toxic microcystin in the summer. This could be relevant to understanding how the blooms that occurred in the mid-20th century in Lake Erie came about, both Microcystis and Aphanizomenon being important contributors to large blue-green blooms at that time. It could also be important in predicting when blooms can be expected.
Prof. Karl Havens, a biologist at the University of Florida (and formerly of the South Florida Water Management District) has discussed the implications of nitrogen and phosphorus as nutrients for blue-green bacteria in Lake Okeechobee, and the need to reduce both given the physical and biological complexities in a shallow lake.
It has been known for some time that non-nitrogen fixing bacteria are highly competitive when it comes to ammonium compounds in freshwater lakes, possibly explaining why Microcystis and similar blue-green bacteria do achieve dominance in the blue-green blooms when in proximity to agricultural run-off.
Researchers are looking for ways to monitor assess and predict algal blooms of all types. This can be done by sampling the lake waters and analyzing them for various organisms and chemical compounds, such as Dr Beversdorf did for his detailed study of Lake Mendota. However, in very large lakes such as Lake Erie the shear size of the lake makes rapid response to a growing giant algal bloom impossible.
Prof. Joseph Ortiz of Kent State University, Ohio has been actively involved in developing new ways to gather information on giant blue-green bacterial blooms using an instrument on board the International Space Station. From space it can image all of Lake Erie in two days – remember Lake Erie is about 9,900 square miles (241 miles long, 57 miles wide). He uses a technique called hyperspectral visible derivative spectroscopy, quite a mouthful but very important. The hyperspectral imager works in orbit about 220 miles above the Earth’s surface and transmit the results to Dr Ortiz who uses sophisticated analytical methods to identify various types of algae and bacteria in the lake water.
This and related techniques are now being used to forecast blue-green bacterial blooms, in cooperative ventures between NASA and NOAA (National Oceanographic and Atmospheric Administration). For example this was their forecast summary for 2014:
“This year’s forecast is for a western basin Lake Erie cyanobacteria bloom of 22,000 metric tons dry weight (MT), with a 95% predictive interval of 11,000 to 33,000 MT. The bloom size over the last decade (2004-2013) has averaged 14,000 MT, such that this year’s bloom will likely be above average. However, the 2014 bloom is expected to be less than the record bloom of 40,000 MT, which occurred in 2011.”
In August of 2014 the City of Toledo shut down its water supply because of contamination by blue-green bacterial toxins (microcystin), which made it undrinkable for 400,000 residents, confirming the astonishing power of this predictive method.
A Florida Mismanagement Plan for Niagara Falls
Just imagine if the same planning “logic” had been applied to Lake Erie as has happened with Lake Okeechobee. In the case of Lake Okeechobee, agricultural interests took over an Everglades river and associated sawgrass wetlands to drain them for use as sugar plantations. To do this the ancient course of an Everglades river was disrupted by damming its 25-mile wide outflow from Lake Okeechobee, upstream from the Everglades Agricultural Area. In so doing the lake level rose because it had no other natural outlet. Therefore higher shoreline dike construction was needed (the Herbert Hoover Dike) to impound the water to prevent flooding of the adjacent land. All this destroyed a large part of the Everglades, a natural wonder of the world designated an International Biosphere Reserve and a World Heritage Site by UNESCO and a Wetland of International Importance. The “river of grass” in the Everglades became starved for water.
Everglades River of Grass
Meanwhile, the Kissimmee River feeding into Lake Okeechobee and draining another agricultural area was straightened and canalized to remove those annoying meanders that characterize river systems as they approach local base level (the lowest point to which a river can flow). The straightened channels thus allowed rapid fertilizer run-off from the fields, preventing filtering and bio-cleansing in the natural wetland vegetation of the flood plain meanders that would otherwise exist, further contributing to heavy phosphorus loading in Lake Okeechobee and the consequent blue-green bacterial blooms. The straightened channels also contributed voluminous extra water that the lake could not handle. Therefore, the lake managers and flood controllers (the Army Corps of Engineers) directed the overflow waters down a number of canals with outlets to the highly populated Atlantic and Gulf coastlines and the sea, the overflow water being heavily polluted with blue-green bacteria from the giant blooms that grew in the lake.
So let’s work this through for our imaginary Niagara Gorge Agricultural Area, a 7-mile stretch that would be ideal land for growing grapes and other fruits in a valley just below Niagara Falls. Once drained, the imaginary agricultural area would eventually develop lime-rich soils, which would be perfect for high quality wine grapes, and would be similar to the soils in the adjacent Niagara Wine Country. The fruit would be sheltered from the worst of the Canadian winter that might otherwise be unfavorable for growing and ripening the grapes. There would be one big problem: there is too much water in the Niagara Gorge, which transports the Great Lakes waters through the Niagara River into Lake Ontario.
So, the imaginary managers deemed that a dam would be necessary across the Niagara River upstream from Niagara Falls to divert the water elsewhere, and help to drain the Gorge. They knew this would be entirely possible because the Army Corps of Engineers had dammed the Niagara River once before to make repairs to the Falls, back in 1969. Of course, the magnificent Niagara Falls, a real wonder of the world, would cease to exist. Meanwhile, the Lake Erie water level would start to rise and bigger and better dikes would be needed, particularly around population centers such as Buffalo, Cleveland, Toledo, and Detroit, to prevent flooding. This in turn would raise the base level of the inflowing rivers and they would back up and tend to flood more frequently. The imaginary managers decided to straighten the meander channels of the rivers to allow quicker drainage, but this in turn sent a high discharge of agricultural phosphorus run-off into the Lake. The higher loading of phosphorus triggered gigantic blue-green bacterial blooms.
Clearly an outlet would be needed for the imaginary re-engineered Lake Erie high-level water, so the imaginary lake managers decided to discharge the lake water somewhere else. Very fortunately, an older structure – the Erie Canal – still existed and would be ideally suited for modification to act as a spillway or overflow channel. The Erie Canal in turn would channel the water from Niagara into the Hudson River and out into the Atlantic Ocean near New York City. Unfortunately the voluminous discharge of polluted freshwater from the Lake would do two things. First, the blue green bacteria would thrive as the discharge water slowed and became semi-stagnant in the estuaries and coastal regions around Manhattan during the summer. Secondly, the marine wildlife would be severely impacted due to the drastic reduction in salinities by mixing with freshwater. This would lead to the mass death of marine life, together with animals and plants that thrive in marginal marine and brackish environments such as oysters and clams. Millions of New Yorkers and those in adjacent areas would become enraged because the grape and fruit growers in the Niagara Gorge Agricultural Area have caused all this in the first place, due to their insistence on the change of land usage. Meanwhile, the farmers in the newly established Niagara Gorge Agricultural Area are thriving and unaffected by these changes, and blame the towns and cities for inadequate sewage treatment and leaky septic tanks.
Of course, all this is nonsense and absurd – a figment of my imagination. It wouldn’t happen in real life, would it? No one could be that inept or uncaring – or could they?
The chances of such a catastrophe happening in real life are very slim in the Niagara region. Any move by a special interest group planning to monopolize a Great Lakes’ resource would come under the immediate scrutiny the International Joint Commission. In all likelihood they would jump on such a rapacious scheme like a ton of bricks and it would never see the light of day.
It’s a great pity that the people of Florida don’t have an equivalent body with overarching responsibility for maintaining the quality of Florida waters for all Floridians. Unfortunately, sensible planning initiatives over the decades have been circumvented, and most state politicians have been incapable or reluctant to fund policies directed towards protecting Florida’s water resources. It is a dismal story of failure to protect Florida’s natural resources, and continues to be fueled by campaign contributions from Big Sugar to Tallahassee. The more-than-century-long story has been insightfully summarized recently by Jaclyn Blair, a law student at Florida Coastal Law School, Jacksonville, graduating this year (2017) as Juris Doctor. It is recommended reading for anyone wanting to understand the various parts played by corporate interests, citizens concerns, politicians, policies, legalities, and constitutional amendments regarding the destruction of Florida’s natural resources.
I didn’t think up this sub-header, but thanks to PBS for producing a video of that name. In 2007 PBS published this synopsis of their program:
“During the past 125 years, a series of well-intentioned decisions, actions and policies have turned what should have been one of Florida’s greatest natural treasures into an environmental villain. Six thousand years later after if was formed, residents and agencies across the state are now raising the questions: Is it too late for Lake O?”
In 2017 the question is still valid.
Let’s start with the Manager of Lake Okeechobee, the South Florida Water Management District (SFWMD), which describes itself as follows in its mission statement:
“OUR MISSION: To manage and protect water resources of the region by balancing and improving flood control, water supply, water quality and natural systems.
The South Florida Water Management District is a regional governmental agency that manages the water resources in the southern half of the state, covering 16 counties from Orlando to the Florida Keys and serving a population of 8.1 million residents. It is the oldest and largest of the state’s five water management districts. Created in 1949, the agency is responsible for managing and protecting water resources of South Florida by balancing and improving flood control, water supply, water quality and natural systems.
A key initiative is restoration of the Everglades – the largest environmental restoration project in the nation’s history. The District is also working to improve the Kissimmee River and its floodplain, Lake Okeechobee and South Florida’s coastal estuaries.”
Now, let’s take a look at Lake Okeechobee’s basic statistics. It is 730 square miles in area (about 36×29 miles in longest dimensions), very shallow with an average depth of about 9 feet, varies from about 12 ft to 18 ft above sea level, and has a total volume of water of about 1 cubic mile (for comparison, Lake Erie is more than 100 times greater in volume but only about 13 times larger in water surface area). Lake Okeechobee is the largest lake in the contiguous United States, outside the Great Lakes.
Until about 1930, the lake had a natural outflow about 25 miles wide on its south side allowing water to enter the Everglades system. From about 1930 to 1960 a dirt dam was progressively built, 143 miles in length, and extended all around the Lake as the Herbert Hoover Dike. This converted Lake Okeechobee from a dynamic system of seasonal inflow and outflow into a semi-stagnant reservoir, with emergency releases of overflow water into canals discharging east and west into the Atlantic Ocean or the Gulf of Mexico, along heavily populated coastal areas.
SFWMD has scientists and engineers working on various aspects of water quality in south Florida, including Lake Okeechobee. For more than half a century, the Lake Managers have been collecting information on water quality such as water chemistry, amounts of phosphorus and nitrogen, temperature, turbidity, and so on. That, of course, is their job as a management agency, and each year they and their contractors collect more than a quarter million samples for analysis, many from Lake Okeechobee. In addition, NOAA has a weather station on the southern rim of the lake and these meteorological data can be integrated with the Managers’ observations on lake water. This is really important information. However, their attention to details of biological data seems to be less precise. Their definitions of bloom formation is based, generally, on the amount of a particular type of chlorophyll extracted from water samples, rather than information on the number and concentration of particular types of bacteria or algae. Nevertheless their information is important, and the Lake Manager’s scientific staff have produced many significant reports analyzing these data to try to explain why bacterial blooms form in the waters of Lake Okeechobee.
Of first rank importance was the assessment by the Lake Manager’s scientists that Lake Okeechobee was eutrophicating, that is becoming enriched in dissolved nutrients (such as phosphates) that stimulate the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen.
Another report by the Lake Manager’s scientists documented the continuing increase and doubling of total phosphorus in the Lake between 1973 and 1984. Fluctuating lake levels and/or resuspension of soft bottom muds my have been involved in the increase. However other studies drew attention to the burgeoning intensive dairy and beef cattle industries to the north, starting in the 1950s, providing nutrients from agricultural run-off flowing down the Kissimmee River into Lake Okeechobee, together with nutrients entering the Lake system from the sugar cane industry to the south of the Lake, often by back-pumping.
Other scientists employed by the Lake Manager attempted calculations to balance the amount of phosphorus flowing from the Kissimmee River into the Lake from the cattle farms to the north, compared with the amount being discharged principally through the St Lucie and Caloosahatchee Canals to the east and west. Their numbers suggested that between 1973 and 2002, each year on average almost 300 tons of phosphorus ended up sinking to the bottom of the Lake. In the early 2000s the situation had reached crisis proportions because the bottom sediments in the Lake had become thoroughly saturated with phosphorus. Any further phosphorus would not have bonded firmly to the bottom sediments but would be available in the lake water for biological activity. In other words, eutrophication was predicted to become much worse, which meant more organisms growing in the lake waters.
Other studies by the Lake Manager’s scientists looked at meteorological information from NOAA and discerned a complex inter-relationship between wind speed, rainfall, inflow from the Kissimmee River, and lake levels, apparently related to “algal” (i.e. bacterial) bloom formation (that is as judged by the amount of chlorophyll extracted from water samples). They also noted a steady increase in lake levels between 1972 and 1978. The maximum amount of algal/bacterial material occurred between May and September in calm summer months when the water temperature typically reaches into the mid-80s.
So the Lake Manager’s scientists had come up with some interesting possibilities as to what conditions promote blue-green bacterial bloom formation, but not everything matched and not everyone agreed. This was a real tough nut to crack. Something seemed to be missing in the puzzle. But some scientists were concerned enough to state in 2009 “that the [Lake Okeechobee] ecosystem is at risk for continued and perhaps worsened eutrophication symptoms under current P [phosphorus] loading conditions.”
Descending the Murky Depths
In 1994 Dr. P. Moore, a soil science researcher attached to the University of Arkansas and Prof. K.R. Reddy of the University of Florida came up with a new idea. It might not be just the lake water that was involved in bloom formation, but the sediments on the bottom of the lake might be implicated in promoting higher phosphorus levels, and particularly the extent of acidity and oxidation or reduction near the sediment-water interface. They arranged for scuba divers to swim down to the lake bottom with special plastic tubes to be pushed into the mud. The divers brought back several cores of the mud for analysis in the laboratory. What they found was that phosphorus can be released from the lake muds when the water mixing with the mud is reducing (i.e. little or no oxygen) and/or acidic, and particularly if iron oxides and iron hydroxides are also present. This is important in a shallow lake where wind can cause the water column to be mixed, bringing oxygen down to greater depths, which assists in retaining phosphorus in sediments. However, in the case of Lake Okeechobee, winds in the calm summer months tend to be minimal, and oxygen concentrations diminish at the lake bottom. Therefore, the reducing conditions help to release phosphorus in the water, just as the water temperatures increase optimally to 75-80 degrees F favoring the growth of bacteria.
Prof. Ramesh Reddy
Glyphosate in Lake Okeechobee
It’s interesting that Dr. Moore’s and Prof. Reddy’s observations about phosphorus release being favored by acid conditions and iron oxides/hydroxides parallels Prof. Spiese’s work on glyphosate in Ohio, which also implicates acidity and iron oxides and hydroxides in the release of phosphorus from cultivated fields and the growth of blue-green bacterial blooms in lakes. Maybe something similar is happening in Lake Okeechobee and surrounding cultivated land.
Well, is glyphosate really present in Lake Okeechobee? I searched the Lake Manager’s website and noted that as early as 2000 glyphosate was being used to exterminate several thousand acres of cattails in and around the lake by aerial spraying.
In addition, the agricultural areas around Lake Okeechobee and in the Kissimmee River watershed are awash with glyphosate, and the farmers appear to have been enthusiastic users since the early 1990s according to the U.S. Geological Survey, whose maps are reproduced below (one for 1992 and another for 2014, but there are others for the in between years).
But the strongest evidence of all for recent years comes from the website of the US Army Corps of Engineers. They head up the Lake Okeechobee Aquatic Plant Management Interagency Task Force, which has this mission statement:
The Corps of Engineers shall chair, and actively solicit participation in the Lake Okeechobee Aquatic Plant Management Interagency Task Force. The Task Force members will represent State of Florida agencies (including the Florida Fish and Wildlife Conservation Commission and the South Florida Water Management District), state Universities, the Corps of Engineers, and other Federal agencies. The Task Force will serve in an advisory capacity, providing multi-disciplinary technical and scientific data from which the Corps’ aquatic plant management strategy, methodology, and research planning and operational efforts will evolve. The focus of the aquatic plant effort will be to benefit the overall ecological health of Lake Okeechobee.
So now it seems that there are two lake managers: The US army Corps of Engineers on the one hand, and the South Florida Water Management District on the other. The Army Corps of Engineers, as well as having absolute authority to open the floodgates for Lake Okeechobee whenever it deems this necessary, has also now got control of the program to exterminate various aquatic plant species by use of powerful herbicides. Is this a matter of too many chiefs and not enough Indians? The Mission of the Army Corps of Engineers is clear: The U.S. Army Corps of Engineer’s mission is to provide vital public engineering services in peace and war to strengthen our Nation’s security, energize the economy, and reduce risks from disasters. Their Vision is equally clear “Engineering solutions for our Nation’s toughest challenges.” Their Motto is clear “Building Strong”. The potential conflict between the two Managers (ACE on the one hand, SFWMD on the other) needs to be rationalized and sorted out to achieve sensible results.
So what can ACE tell us about glyphosate? From time to time the Army Corps of Engineers posts their schedule for spraying programs to control aquatic plants in Lake Okeechobee. For example, they used glyphosate in July 2016 for extermination of cattails in Lake Okeechobee and again in March 2017. So glyphosate is present in Lake Okeechobee, definitely from Army Corps of Engineers’ activities and the SFWMD, starting as early as 1988:
The presence of glyphosate is highly probable from farming activities around and upstream from Lake Okeechobee. It has already been noted that glyphosate may stimulate blue-green bacterial growth, and that the cloning by natural selection of glyphosate-resistant strains is also possible. The Lake Managers have yet to come up with an up-to-date, complete analysis of Lake Okeechobee waters, showing how much herbicide is present – at least I have not been able to find it on their websites or other relevant publications – and how many toxins such as microcystin have been detected on a routine basis. Surely the public has a right to know this vital information.
Where has all the Water Gone?
Well the problem is that the water in Lake Okeechobee generally does not go anywhere, or not where it is meant to be, that is into the southern Everglades. The various planning decisions and missteps over the years have converted Lake Okeechobee into a vast semi-static reservoir. From time to time it gets overfull, even with an enlarged dike, and great volumes of water have to be released by the Army Corps of Engineers to the St Lucie River and the Caloosahatchee Rivers with dire results.
An impressive report appeared in 2015 by a team of experts headed up Prof. Wendy Graham of the Water Institute of the University of Florida. The title of the report says it all: “Options to Reduce High Volume Freshwater Flows to the St. Lucie and Caloosahatchee Estuaries and Move More Water from Lake Okeechobee to the Southern Everglades. An Independent Technical Review by the University of Florida Water Institute”.
It is a very detailed and comprehensive report and well worth reading because it was produced independently at arm’s length from the politicians, and it is for the most part written in plain and comprehensible language. It discusses many options to solve the problem and to start getting the lake water back down to the southern Everglades.
To my mind, the key thing is to include bio-cleaning and remediation of the lake water before it passes south too far down the Everglades system. Constructed wetlands for water treatment have been in use since the mid-1950s, including several system using cattails, reeds, and other aquatic plants to remove such things as nitrogen, phosphorus, and other pollutants from waste water. Such systems could be utilized to good effect in the reservoirs anticipated in areas south of Lake Okeechobee, in effect being “reconstructed wetlands” in place of the former sawgrass plains.
To its credit, the South Florida Water Management District has constructed several large wetlands called Stormwater Treatment Areas, which are designed to remove excess phosphorus and other nutrients from waters immediately north of the Everglades Protection Area. One of them in western Palm Beach County STA-3/4) is the largest constructed wetland in the world.
If the overflow water from Lake Okeechobee is not cleaned to rigorous standards, it will fail to reach the high standards of purity required by federal regulators of the Miccosukee Indian tribal lands in the Everglades south of Alligator Alley (see my blog “Sugar and Indians”):
Well, all the above makes for pretty dismal reading for the most part. But there are several rays of sunshine cutting through the mess that has been created to suggest that all is not lost. Up in Lake Erie there’s a lot of activity on both sides of the border in reconstructing wetlands to replace those lost to drainage and infill schemes over the last century. New treatments are being invented to remove phosphorus and other pollutants from the run-off water before it hits the lake. Some of the links below will lead you to more details.
Down in Lake Okeechobee, the South Florida Water Management District is showing the world how to build gigantic constructed wetlands as a start to cleaning up the Okeechobee water ultimately destined for the southern Everglades. And Florida’s politicians are now making major inroads into passing legislation to fund these schemes, such as Senator Joe Negron’s continuing efforts to get the state House and Senate to agree.
I am lucky to know a lot of people who are smarter than me. And one of them is my brother. Ever since we were kids Todd read meteorological books or the Guinness Book of World Records. He likes data. Today, over forty years later, he is helping me apply his knowledge of data to the St Luce River/Indian River Lagoon.
If you are a regular blog reader, you know that this past summer Todd helped publicly identify what became a 240 square mile algae bloom in Lake Okeechobee that was being released into the C-44 causing our river to become toxic. Today, I will share his ideas on avoiding the perfect toxic algae storm.
Here is a photo of Todd and I when we were young in the 70s, when the river was in better shape and we were having fun fishing on Ronnie Nelson’s dock on Hutchinson Island.
Here is a photo of Todd and me today. As you can see we have changed a lot and the river has changed too…
After studying these satellite aerials for a while, I can tell that the blooms are definitely related to sunlight and wind..Our scientists friends would sarcastically say, “no kidding?!”
High pressure system -> a lot of sunlight + no wind = bloom. Clouds + wind = less algae.
The fresh water, phosphorus and nitrogen are always in the lake, but not necessarily the river. Luckily, cloudless days are also the perfect time to spot the algae by satellite.
Maybe the ACOE should add to their discharge schedule that they will hold back the releases when it is forecast to be calm and sunny for several days to prevent the risk of and bloom in the estuaries? Then they can pulse the releases again when the clouds and wind pick up and the algae blows away in the lake – kind of like mother nature.
Jacqui: “Always better if we go with Mother Nature so we don’t end up with such ecological disasters…”
Todd: ” I think Gary Goforth, Mark Perry and others would tell us that the disaster timeline sets up like this:
– A low pressure weather system moves into Florida and dumps a bunch of rain, local runoff begins and the lake starts to rise
– They keep S-308 at Mayaca an other lakeside gates closed and open S-80 because the priority is always to transport the “local” runnoff first and not add to flooding problems by sending lake water through the coastal canals
– The local basins start to drain out and a high pressure weather system moves in. It gets sunny, hot, and the wind dies down to zero.
– With a lot of sun and no wind, the lake starts to bloom. With local runoff subsiding, the tides help flush all to local runoff out to sea but not completely.
– Just when conditions in the lake are “the perfect storm”, the estuaries would otherwise be recovering from the local runoff, the lake is in full bloom and rising, S-308 is now opened to drop the lake at the worst time. All the algae that just exploded in the lake is transported down C-44 through S-80 and into to estuaries. Salinity in the estuaries stays low instead of naturally recovering. With the sunny conditions and unnatural discharges, the estuaries explode with algae blooms.
If they would just delay opening S-308 for just a few days, maybe a week, allowing clouds and wind to return, could the perfect storm be avoided?”
You can access more of Todd’s shared data here under FIRM FAVORITES: http://www.thurlowpa.com
Thank you Todd! Hope the ACOE thinks on this. We don’t want to get in the Guinness Book of World Records 2016 for the estuary with the most toxic algae blooms!
As we know, my brother Todd has been keeping his eye on the Landsat satellite images as they provide tremendous insight into the condition of Lake Okeechobee and potential algae blooms that affect the health, safely and welfare of those living around the St Lucie River/Indian River Lagoon. Todd notes that in studying the Landsat images: “Perhaps the algae grows on Rocky Reef? The area just north of this location is were some of the earlier blooms originated.”
Hmmm? Could the Rocky Reef be an area where the water cannot flow in the lake as easily due to its nature? Could it be possible that nutrient rich back pumped waters from the sugar fields fester in this area feeding a lake wide bloom? Worth a thought as we try to fix our problems…
The toxic algae blooms –people are still talking about them….
You may have noticed recently in various publications and “Letters to the Editor” across the state that some are calmly claiming that “algae blooms have been occurring in Florida since the beginning of time…” This may be true, however, this summer’s 240 square mile algae bloom in Lake Okeechobee that led to the outbreak in the St Lucie River was unprecedented. Comparing the situation to prior algae bloom outbreaks of 2013, 2014, or any other is like comparing a dog to a wolf. The same but very different.
Another interesting thing Todd stumbled upon while researching the “Rocky Reef” located basically above Clewiston was a 1977 joint NASA/SFWMD report on, of all things, using Landsat radiance data to study the turbidity and chlorophyll concentrations in Lake Okeechobee.
Since obviously the South Florida Water Management District has been using the Landsat information since 1977, and Martin County has been paying taxes to the District since around the same time, I think it would have been polite if the District had let us know when Lake Okeechobee’s then poisonous waters were overflowing with algae and headed this way. Don’t you as well?
You can learn about Todd’s discoveries about the Rocky Reef below.
Thank you Dr Goforth for allowing me to share this update. Through knowing our subject, we shall prevail! Jacqui
Subject: Updated Lake discharge information, August 23rd, 2016
Updated flows and loads attached.
Since January 1:
· 178 billion gallons of polluted Lake water has been discharged to the St. Lucie estuary, equal to 24% of all Lake discharges. This foul water dumped millions of pounds of pollution into the estuary:
o 247,000 pounds of phosphorus
o 2.4 million pounds of nitrogen
o 47.5 million pounds of sediment
· 372 billion gallons of polluted Lake water has been discharged to the Caloosahatchee estuary, equal to 50% of all Lake discharges. This foul water dumped millions of pounds of pollution into the estuary:
o 325,000 pounds of phosphorus
o 4.7 million pounds of nitrogen
o 19.3 million pounds of sediment
· 21.4 billion gallons of polluted Lake water has been discharged to the Lake Worth Lagoon, equal to 3% of all Lake discharges.
· 45.4 billion gallons of treated Lake water has been discharged to the Everglades, equal to 6% of all Lake discharges, and 60% less than last year at this time.
· 12.6 times more Lake water has been sent to the estuaries than to the Everglades
Despite the high pollution load from the Lake to the St. Lucie estuary in 2016, agricultural runoff has contributed about 70% more phosphorus pollution, and almost as much nitrogen pollution.
Recently, Senator Joe Negron proposed as part of his goal-set as incoming Senate President the purchase of lands in the Everglades Agricultural Area south of Lake Okeechobee. The idea of a reservoir is not a new one, but is certainly an idea whose “time has come.” To have the Present of the Senate supporting this idea is unprecedented!
As we move forward, it is important to know that this concept has been “on the books” since the beginning of Everglades restoration and is doable. We have all been really fighting for land since 2013, but the Comprehensive Everglades Restoration Plan took shape in 2000. Unfortunately is not taking shape very quickly as it is caught in the tar-pits of government and can’t seem to break free.
So now we the state must take leadership.
The chart I want to share with you– in case you are unfamilar —so you can see the “tar-pit”— has a confusing name.
It is called the “Integrated Delivery Schedule” or (IDS).
But what does that mean?
The Army Corp of Engineers “IDS” as seen above, in many colors, is like a goal sheet, but because there are so many moving parts going on simultaneously and they because they are dependent on each other, the chart is multi-dimensional rather than just “one, two, three.” Nonetheless, the projects are “in order”…just think of it as a “list of things to do” from top to bottom…as the money comes in and the ACOE tries to get things done between politicians and stakeholders fighting.
OK to stick on point, I want to call attention to the bottom of the sheet. Third from the bottom in white you will notice a line that reads: “EAA Storage & ASR/Decomp Ph2.”
EAA storage is referring to water storage for Lake Okeechobee in the EAA; ASR is an entire other subject–like deep injection wells in the aquifer to store and retrieve water. Obviously the two concept were seen to work together.
It is all very complicated and I will write more about it in the coming months, but Senator Negron’s proposal has the potential to put the EAA reservoir higher up on the list, save the St Luice River/Indian River Lagoon, promote faster Everglades Restoration and pull us out of the tar-pits.
I for one am very thankful to Senator Negron, and I plan on pulling this Mammoth out by his tusks! 🙂
Here are some insightful links on the subject.
1. “Florida Audubon 2016: The Role of the EAA in Everglades Restoration Storing water in the EAA is one of the central components of the Comprehensive Everglades Restoration Plan (CERP). The EAA Reservoir project in CERP sought to hold water from Lake Okeechobee and farm runoff in the wet season and release this water south in the dry season. A er leaving the reservoir, freshwater would move through the network of man-made filter marshes called Stormwater Treatment Areas to remove phosphorus and other nutrients that are harmful to the plants and wildlife before continuing its path through the Central Everglades, Everglades National Park, and Florida Bay. Although an initial plan for the EAA Reservoir project was developed, the project was not constructed. The original location on for the project is now being used for two shallow water storage structures known as Flow Equalization on Basins (FEB). One FEB is part of the Central Everglades Planning Project (CEPP) project while another is part of the State of Florida’s Restora on Strategies plan required to meet water quality standards. These are important projects, but as recognized in the CEPP plan, the EAA Reservoir project is s ll necessary to achieve the goals of restoration on.1 There is an urgent need for state and federal agencies to come together to plan for water storage in the EAA.” (http://fl.audubon.org/sites/g/files/amh666/f/audubon_eaa_reservoir_may2016.pdf)
Recently, at Rivers Coalition Defense Fund meeting, president Kevin Henderson brought along the old River League’s briefcase. It had been stored away for many decades in an aging house in Stuart. In case you have not heard of them, “The River League” worked tirelessly in the 50s and 60s to stop the expanding destruction of our rivers by the Florida Flood Control District (today’s South Florid Water Management District) and the Army Corp of Engineers.
I couldn’t believe the old brief case—a beautiful sight–aged leather, and rusted metal with the sweat of those who carried it unwashed from its handle…
Kevin placed the briefcase on the table and opened it. It had not been opened in almost 50 years! No pun intended, but the sound of the locks “clicked”and suddenly it was open…
I held my breath.
I swore for a second that I saw the spirit of Ernie Lyons come out of the old briefcase like a genie. He had a giant cigar in his mouth and dark rimmed glasses. His hair was greased back and he sat at a floating desk from the old Stuart News…He was leaning back in his chair with his hands behind his head smiling from ear to ear. His teeth were stained with tobacco juice and he looked happy as a clam.
“Ernie here….Ha! Good to see you workin’ so hard! Those bastards are still killing it aren’t they? The river that is! Don’t you for a moment have despair. As you know this war has been going on for a long, long time. All of us, who have passed, are on your side. We are here. All of us who worked so hard to save the paradise of this place. You’ve probably caught on. Good versus evil is not a game. And I got a secret to tell ya. —I know the end—and good wins. Don’t give up! And know we’re here working the magic behind the scenes to help you save the St Lucie/Indian River Lagoon.”
Then he looked away and started furiously typing…the words he was writing could be seen above his head:
Today’s column, 1968
HOW THROATS OF OUR RIVERS WERE CUT BY CANALS
“There was never anything more beautiful than a natural South Florida river, like the North and South Fork of the St Lucie…
A bank of cabbage palms and live oaks draped with Spanish moss and studded with crimson-flowered air-plants and delicate wild orchids– were scenes of tropical wonder, reflected back from the mirror-like onyx surface of the water….”
When I looked up, Ernie was gone and our meeting was in full discussion…
As a reflection from the mirror of the St Lucie’s onyx-like water–I know that Ernie is here…
Included today are aerial images my husband Ed Lippisch took Wednesday, August 3rd and a satellite image for grand overview.
As far as my husband’s photos, the algae is lessened but it there. Look closely. The above image is of S-308 the structure that allows water to enter the C-44 canal, S-80 and then the St Lucie River/Indian River Lagoon. Algae blooms can be identified even from 1000 feet.
The photos included below may be recognizable to many of you showing other views of S-308, S-80, the C-44 canal and the St Lucie River in the area of Palm City. Alage blooms are present.
The Landsat satellite image also from Aug 3rd was shared by my brother Todd Thurlow. As he notes, “it has been cloudy thus viewing is difficult.” Nonetheless, these images are key to knowing what is going on in the lake.
So thank you Ed! Thank you Todd! We will continue to check things ourselves hoping another toxic algae episode is not on the way. Also Thank you to the ACOE/SFWMD for lessening the discharges from Lake Okeechobee to the estuaries since e June 29th. Better but not best. The long term goal? Clean up this water and re-plumb this state.
I believe in not being dependent on the federal or state government, but what recently happened along the St Lucie River is ridiculous…
In the months following the June 29th, 2016 “State of Emergency”and toxic algae bloom invasion of the St Lucie River, one thing is clear. Our federal and state governments did not look out for Martin County’s best interests, instead knowlingly discharging toxic algae from the lake into the communities along the St Lucie River— with out so much as “public-peep”— until real tragedy and helath risks had struck. Then suddenly, it was like: “Oh my, where did all this algae come from?”
Well, it happened knowingly because the state and federal government (ACOE/SFWMD/ DEP/ Florida Dept of Health) knew Lake Okeechobee was not “popping” here and there with a few algae blooms as is often the case, but rather was”covered in the stuff.”
By July 2nd commonly distributed government satellite images, like the one above, were showing over 200 square miles of algae bloom that obviously had to grow over time to attain such prominance.
Anyway…the least “they” could have done was to have given the public fair warning to be careful and ready as is standard operating proceedure during a drought when wild-fire conditions are present.
But they did not.
Instead, the Department of Environmental Protection quietly took its tests, reporting to the District and the Army Corp– at their leisure— the few results they attained…They should have warned the county government of more than a bloom here and there. They should have told everyone that a dangerous situation was getting ready to occur. But they did not. Maybe they thought it wouldn’t happen? I doubt it. This is true negligence considering the first duty of government is health, saftey and welfare of the people it levies taxes from…
Thus today, I am sharing a brief exchange between my very technically-savvy brother, attorney, Todd Thurlow, and me, from earlier this week. Todd’s shared images will help us look out for ourselves. Thankfully, the recent Landsat satellite images of Lake Okeechobee, for now, look much clearer of algae than just a few months ago.
The link below the exchange will allow you see the satellite images of the lake over time, dates are also present:
Today I am sharing Dr Gary Goforth’s most recent update from July 26, 2016,entitled:
“Updated Lake Flows and Loads to the Estuaries”
This information is disturbing. Please take this information and fight for change in whatever way you can. Thank you. Jacqui
Some observations for the period January 1 – July 25, 2016:
· Inflows to Lake Okeechobee are more than twice what they were this time last year
· Approximately 20 times more Lake water has been sent to the estuaries in 2016 than has been sent to the Everglades; unbelievable…
· Only 20% of Lake releases have been sent south this year, including irrigation for the EAA and other users; only 5% of Lake releases have made it to the Everglades through the STAs this year
· Lake releases to the Caloosahatchee (1.1 million acre feet or about 360 billion gallons) have been about twice the Lake flows to the St. Lucie (0.5 million acre feet, or about 167 billion gallons)
· The duration of the 2016 Lake event for the St. Lucie (178 days) has now exceeded the durations of both the 2013 and 1997-1998 events. Fortunately the Lake discharges in 2016 has been about half the flow that occurred during the 1997-1998 event.
· Lake releases to the St. Lucie have carried more than 8 times the phosphorus TMDL for the entire C-44 Canal, and more than 9 times the nitrogen TMDL … yet FDEP refuses to include the Lake loadings when they assess the C-44 Basin for compliance with the TMDL – unbelievable …
· An estimated 37 million pounds of suspended sediment has been dumped from the Lake to the St. Lucie River and Estuary; much of this accumulates on the bottom as muck.
o Because of the filtration effect of the marsh along the western shore of the Lake, the sediment load to the Caloosahatchee Estuary has fortunately been less – about 20 million pounds.
· More than 220,000 pounds of phosphorus and 2.2 million pounds of nitrogen from the Lake has been dumped to the St Lucie Estuary
o Phosphorus loads from agricultural lands in the watershed have amounted to about 390,000 pounds – 75% MORE THAN FROM THE LAKE
o Nitrogen loads from agricultural lands in the watershed have amounted to about 1.5 million pounds
o Septic tank loading of nitrogen from Martin and St. Lucie counties is roughly 5% of the total nitrogen loading to the St Lucie
· More than 340,000 pounds of phosphorus and 4.8 million pounds of nitrogen from the Lake has been dumped to the Caloosahatchee Estuary.
All brought to you by our leaders in Tallahassee and Washington …
Dr Gary Goforth
Sometimes I feel like I’m living in a Carl Hiaasen novel….
On June 16th, I attended a Water Resources Advisory Commission meeting of the South Florida Water Management District.
Of course, by this time, a 33 square mile algae bloom, parts toxic, had been documented in Lake Okeechobee by the Department of Environmental Protection. The St Lucie River, having been discharged into since January 29th, was looking pretty disgusting. Tempers flared.
At the WRAC meeting, water advocates, not just from Martin County, but from around South Florida were once again pleading with the SFWMD Board of Directors to “endorse buying land south of the lake in the EAA for storage, cleansing and conveyance to the Everglades in order to stop damaging discharges to the estuaries and restore freshwater to Florida Bay.”
“Send the Water South!” rang through the rafters. “Send the Water South!” As usual, the Board looked straight ahead….
And then the presentations came, and a well spoken District scientist started taking about the “The Lake Okeechobee Watershed Project,” and how it is tied into the Comprehensive Everglades Restoration Plan form 2000. —-It’s time had come…
A slide appeared showing pink, green, brown, and blue— representing the watersheds of Fisheating Creek, Indian Prairie, and Taylor Slough northwest of Lake Okeechobee.
According the Army Corp of Engineers who also attended the WRAC “the objectives of the Lake Okeechobee Watershed, or “LOW Project, “are to improve the quality, quantity, timing and distribution of water entering Lake Okeechobee, provide for better management of lake water levels, reduce damaging releases to the Caloosahatchee, and St Lucie estuaries downstream of the lake, and improve the system wide operation flexibility.”
It is a probably good project… No doubt. Do you wonder more about what goes on behind the scenes? Surely….
It is ironic that when the message of the people is “Send the Water South!” the government is finally getting around to “Blocking the Water North!”
Maybe one day we will all be on the same page so our lives don’t seem so much like a characters in a Funny Farm.
Life’s ironies abound.
Here’s the meeting information. A drive from Stuart to Okeechobee is about 40 minutes.
A “Lake Okeechobee Watershed Project NEPA Scoping Meeting will be led by ACOE’ Gretchen Ehlinger, Ph.D. Senior Biologist in the Okeechobee Auditorium, 3800 NW 16th Boulevard, Suite A, Okeechobee, FL 34972, on Tuesday, July 26 with an open house beginning at 6 p.m., followed by an official presentation at 7 p.m.
As this meeting is run by the ACOE, this meeting will only be able to address the LOW Project.
Let’s all attend the meeting even if Dr Ehlinger has to focus on the northern watershed. Maybe we should invite Carl Haaisen?
The following update Comparison of Lake O Releases was shared by Dr Gary Goforth on 7-14-16. Thank you Dr Goforth. The more informed and studied we are about where the water is going, the better chance we have to change this situation.
1. Lake Okeechobee has received more than twice the watershed inflows since January compared to last year at this time.
2. Discharges from the Lake have increased 25% compared to last year this time, however the distribution of inflows has dramatically changed compared to last year (as you so clearly know):
3. Since January 1, a. approx. 525 billion gallons of Lake water have been sent to the estuaries (including Lake Worth Lagoon) b. Lake flows are averaging about 1 billion gallons per day to the St. Lucie River/Estuary and about 2.1 billion gallons per day, and about 0.1 billion gallons /day to Lake Worth Lagoon, for a total of about 3.2 billion gallons per day c. Twenty-five (25) times more Lake water has been discharged to the estuaries than to the Everglades d Ag runoff has contributed significant nutrient loads to the St. Lucie River/Estuary: i. Nitrogen loads: 36% from ag and 54% from Lake [Dear Gov. Scott and SFWMD Board members: Martin County septic tanks contributed about 2% of the nitrogen load] ii. Phosphorus loads: 53% from ag and 30% from Lake e. 93% of the sediment load to the St. Lucie River/Estuary this year has come from the Lake discharges (37 million pounds)
4. Only 32 billion gallons of Lake water have been sent to the STAs this year – less than 1/3 of the amount sent last year at this time.
The Army Corp of Engineers has been discharging from Lake Okeechobee since January 29th and toxic algae from the lake has been released into our St Lucie River. We are being invaded. This is horrific for the people, but what about the animals? Thank God someone is documenting their plight….
Facebook friend, Rebecca Fatzinger, is not only a voice for the St Lucie River/Indian River Lagoon, but for its wildlife. With the cries of the people “loud and clear” sometimes it seems the animals are but an afterthought for our local, state, and federal government.
I can’t help but wonder….
The Florida Wildlife Commission? The Department of Environmental Protection–have you written a statement about the wildlife implications of this bloom? What are you thinking? Are you allowed to say?
How could the St Lucie River/Indian River Lagoon once have been the most bio-diverse estuary in North America? How could we be home to some the state’s most important aquatic preserves?
Thank you to Rebecca for documenting and giving us an up close look as the animals try to cope.
