Today, I wanted to share new map images, “Selected Release Volumes, November 1st, 2018, to May 7, 2019,” being presented at the South Florida Water Management District by Chief District Engineer, John Mitnik P.E. Thank you to Mr Mitnik and his staff for these great images. I really like them and I think you will too as they specifically break down the movement of water from north to south, using color-coding and arrows, making it easier to see and understand the water flows of the complicated Lake O system.
Looking above, notice that the map starts at the top with Orlando’s free-flowing creeks, the often forgotten headwaters of Lake Okeechobee and Kissimmee Chain of Lakes: Their names? “Reedy,” “Shingle” and “Boggy.” Sounds like names from an Everglades’ Seven Dwarves, don’t they?
As you study the map images, above, and below, you’ll catch on quickly with the color-coded arrows and numbers in acre feet. If you wish to compute, use my brother, Todd Thurlow’s easy conversion chart for acre feet: (http://eyeonlakeo.com/DischargeDataandTools/EyeOnLakeOAcreFeetConverter.html)
I’m not going to review each line, just some highlights…but please read through it all!
If you live in Martin or St Luice County, you may find of particular interest RED, RELEASES TO THE INDIAN RIVER LAGOON, (C-25 at Taylor Creek); and BROWNISH-RED, UPPER EAST COAST, DISCHARGES TO THE ST LUCIE ESTUARY, (C-23 and C-24); for all of us BLUE, TOTAL RELEASES SOUTH, is always important! 550.6 thousand acre feet is really a lot of Lake water “going south.” The original Everglades Forever Act proposed 250,000 acre feet, but it has not always worked out that way. Some years have been basically null. We should be very happy about 550.6!
On the southern map you’ll see some of the same colors and number and new ones like OLIVE GREEN, LAKE RELEASES EAST AND WEST; and many more. Most interesting to me right now as the estuaries are not getting bombed is LIGHT GREEN, WATER CONSERVATION AREA 3 RELEASES TO EVERGLADES NATIONAL PARK linked to the L-29 Canal along the Tamiami Trail. It is not just how much water is going south, but how much is getting to the right part of Florida Bay as it is hyper-saline, in parts, leading to massive seagrass die-off. This problem was the first to inspire change and it is still messed up….
In any case, I hope you enjoy these images as much as I do! And following such will certainly help us attain our goals!

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.
As Florida matured came Governor Claude Kirk, a republican, in 1968, who was advised by environmentalist Nathaniel Reed. Then came Governor Reubin Askew, a democrat. The Florida Legislature, seeing the destruction of the state’s natural resources, passed a very important piece of legislation, the “Florida Water Resources Act,” today’s Chapter 373 in Florida Statures. (http://www.leg.state.fl.us/statutes/index.cfm?App_mode=Display_Statute&URL=0300-0399/0373/0373ContentsIndex.html)
This law created five Florida water management districts with expanded responsibilities for regional water resources management includingenvironmental protection not just flood control.
Accordingly, the Central and South Florida Flood Control District changed its name, but not its heart, becoming the South Florida Water Management District, we know today…(https://www.sfwmd.gov)

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!
Last Thursday on November 16, the ACOE reported they will reduce the amount of water they are releasing from Lake Okeechobee. The Corp had been releasing at a high rate, on and off, since September 20th. New targets are 2800 cfs east and 6500 cfs west.
Photos below were taken yesterday, 11-19-17 by my husband, Ed Lippisch. We will continue to document the discharges from Lake O, and area canals.
As Thanksgiving approaches, we are thankful the discharges are lessened and that the SFWMD and the public are working hard to plan the EAA Reservoir Senator Negron fought for… We the people of Martin County, will not be satisfied until these discharge stop. The river has its hands full with unfiltered discharges draining agriculture and developed lands from C-23, C-24, C-25 and C-44. All must be addressed.
“And where the river goes, every living creature that swarms will live, and there will be very many fish. For this water goes there that the waters of the sea may become fresh; so everything will live where the river goes…” Ezekiel
I am very fortunate to have a small army of people helping me document the Lake Okeechobee discharges this year. Presently, it is the tremendous rate of government sponsored discharge from Lake O that is destroying the regions’ economy and ecology, right before our eyes, ~once again.
Friends of my husband, pilots Dave Stone and Scott Kuhns, took these aerials yesterday, 11-8-17 around 5 pm. When I asked Scott about the plume, he relayed that it went 15 miles south almost all the way to Jupiter Inlet, and since there is also rain driven, fresh, dark- stained water flowing out of the Jupiter Inlet (not over-nutrified, black-sediment water from Lake O) there was no clear delineation of blackened plume to aqua ocean water, like usual–rather, the waters are all dark….
“How far did the plume go east from the St Lucie Inlet?” I asked. “From the coast, as far as the eye could see…”
*Lake O level:http://w3.saj.usace.army.mil/h2o/currentLL.shtml
*The ACOE has been discharging from Lake O since Hurricane IRMA hit on Sept 2oth, 2017. The rate of discharge has gone up and down, however increasing over recent weeks. Word is the St Lucie could be dumped on for many more months, possibly through the end of the year. So don’t count on taking your visiting relatives out fishing this holiday season even though you moved here for the water. This ecological disaster is finally seeing light at the end of the tunnel as Senator Joe Negron, alongside the public, and “River Warrior” groups, particularly Bullsugar, has pushed so hard that the SFWMD and ACOE are finally working towards building an EAA Reservoir that will begin the long journey of changing water drainage culture in South Florida, and “sending the water south.” Please get involved and learn more by viewing this SFWMD EAA RESERVOIR website:https://www.sfwmd.gov/our-work/cerp-project-planning/eaa-reservoir
*Thank you to the people, and the children, groups such as the C4CW, Rivers Coalition, grandparents’ HOA email chains, leadership at Martin Health System, and to the those working for the agencies trying to help the St Lucie. As the River Kidz say:
Whereas, if the ACOE’s discharge waters of Lake Okeechobee were “filling up the City of Stuart,” last Thursday, October 26, these polluted waters, would have reached the top of Stuart’s iconic 134 foot water tower…
Whereas, once again, our economy and ecology is completed devastated, and high bacteria levels in the water are exacerbated therefrom….We shall remember this day…
We shall, therefore, designate, Thursday, October 26, as “Water Tower Day” and say together: “Lake O discharges have reached the top; this must STOP!”
Yes, to put the Lake Okeechobee discharges into perspective, last Thursday the cumulative 2017 ACOE/SFWMD discharges from S-80 passed 134 “Stuart Feet”. The Stuart water tower is 134 feet tall. See my brother Todd’s cumulative total page below:
St Lucie River Discharges
S-80 Cumulative Total 2017: http://www.thurlowpa.com/LakeOLiveData/2017/
– In the lost summer of 2013, Stuart/Martin County received 284 “Stuart Feet”, 2.1 times the height of the tower.
– In 2017, the gates did not open until September 5. So it took only 52 days to accumulate that same amount of discharges!
– In 2013, the discharges started on May 8 (with the exception of some small pulses earlier in the year). That year, it took 91 days to hit a cumulative “134 Stuart Feet” – on August 7.
In other words, the discharges have been almost twice the rate as they began in 2013. You can see this in the slope of my brother’s graphs in the web page above. This doesn’t really mean a lot though. In 2013 the discharges didn’t really begin to accelerate until mid-July. At that point, the rates of discharge were comparable to what we are getting now.
– At the current average of about 4200 cfs, we would hit the 2013 total of 284 Stuart feet in another 42 days (December 9). If they are saying the discharges could continue for months, this could happen. We could have another record year, even though the disaster didn’t start until September. Maybe they will throttle it back a little or start pulsing again so it won’t be the case. In any event, this is already another lost year…

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.
Save the St Lucie! Save the Indian River Lagoon!
Links to ACOE website: See S-80 & S-308, others intesting too. Northern waters should also be cleaned! http://w3.saj.usace.army.mil/h2o/reports.htm
“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
Hurricane Irma may be gone, but her waters are not. Our now black river and the giant plume off the St Lucie Inlet attest to this. Clean rain that fell in our region during the hurricane is now filthy “stormwater” discharging, unfiltered, through manmade canals C-23, C-24, C-25, and C-44. Nature did not design the river to directly take this much water; this much water kills.
Every plume looks different, and this one is multilayered with no clear border. Sediment soup, black-brown in color, yesterday it extended out about 2/3 of a mile into a stirred up Atlantic and flowed south, in the rough waves not quite having made it to Peck’s Lake.
Since Hurricane Irma’s rains, area canals dug with no environmental foresight in the 1920s and 50s for flood control, and to facilitate agriculture and development, have been flowing straight into the river. On top of this, in anticipation of the hurricane, three days prior to IRMA the Army Corp of Engineers began discharging from Lake Okeechobee. During the hurricane they halted, and then started up again at high discharge levels reaching over (4000 cfs +/-) this past Friday, September 15th. As Lake Okeechobee rises and inflow water pours in from the north, and is blocked by the Everglades Agricultural Area in the south, we can expect more Lake O discharge on top of the canal releases themselves.
As advocates for the St Lucie River we continue the fight to expedite the building of the EAA reservoir and to create a culture to “send more water south.” In the meantime, we, and the fish and wildlife, and the once “most bio diverse estuary in North America,” suffer…

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…
Barley Barber Swamp, the FPL Reservoir and its 1979 Catastrophic Failure (Part 2 of 2), Todd Thurlow, SLR/IRL
Video link “The FPL Reservoir’s Catastrophic Dike Failure” (https://youtu.be/2r1hgFqgIK8)
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.

Sometimes it seems there is not a piece of land that doesn’t have the mark of modern-humans on it…but then, we have been leaving our mark for thousands, and thousands of years…
On a recent trip with renowned South Florida photographer Edward Carr, my husband Ed and I flew over the contiguous Dupuis and J.W. Corbett Wildlife Areas ~ “bordering” Martin and Palm Beach counties.
It was quite a view, and I felt embarrassed that I did not know more about these wonderful remaining lands located so close to home. So interesting to see them in a more natural state. The circles of trees, dome-like, standing in shallow water. Shades of green, brown, and blue changing and reflecting with every turn. An animal running into the bush. What was it?! A deer? A panther?
I have to admit, chasing toxic algae sometimes overtake me!.. I must remind myself “to stop and smell the pond apples!”
Mr Carr was photographing for a documentary on “Big Mound City” the most remarkable of places our human ancestors called home. These native people of Lake Okeechobee’s Belle Glade Culture, built mounds to get above the swamp rather than trying to drain it….as sea level rises, we many have to consider this once again just like the FEMA project in Sewall’s Point!
I find this entirely fascinating…history repeating itself…
I tried to get Ed later in that week to go with me into Corbett for a hike and to explore, but he said it’s too hot right now, he rather fly. It would be “torture in there.” Well, when the weather cools down, I am taking him. What a wonderful piece of natural history to have right in your own back yard.

“State Says Blue-Green Algae in Lake Okeechobee is Not Toxic,”
WPTV, link 7-26-17: http://www.wptv.com/news/region-okeechobee-county/state-says-blue-green-algae-in-lake-okeechobee-is-not-toxic
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.”
See everyone soon.

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

The day before yesterday, I received an email from my mother. It read:
“I was watching TV and it looked like “our” toxic algae is going to be in the Changing Seas program tomorrow night on PBS at 9.”
She was right! So glad she let me know as I may have missed it. If you did, you can view on link below.
Toxic Algae: Complex Sources and Solutions:
There is incredible footage of the 2016 toxic algae event caused primarily by forced discharges by the ACOE and SFWMD from Lake Okeechobee into the estuaries, St Lucie and Caloosahatchee. South Florida locals such as Mary Radabaugh, Dr Edie Widder, Dr Brian LaPointe, Mark Perry, Phil Norman, Dr Larry Brand, Dr Steve Davis, and Col. Jennifer Reynolds are prominently featured. Edie Widder’s political commentary at the end is priceless.
CHANGING SEAS Toxic Algae: Complex Sources and Solutions. Aired: 06/21/2017
Water releases from Lake Okeechobee periodically create putrid mats of blue-green algae. Scientists think water pollution is to blame, and if something isn’t done about it there could be irreparable damage to the environment, the local economy and people’s health.
You can Like Changing Seas on Facebook and attend their DIVE IN Summer series on this topic June 28th, 2017. See link:
TCPalm’s Elliott Jones reported this morning that Stuart has received a whopping 11.30 inches of rain just so far this month! (The average being 7.14.)
Although due to the recent drought, the ACOE/SFWMD are not dumping Lake Okeechobee through Canal C-44, canals C-23, C-24, C-25, and areas along C-44, as well as our own basin, are draining right into the St Lucie River/Indian River Lagoon. Very little of this water is cleansed before it enters and thus is damaging to the eco system. Next time you see water draining through a grate in a parking lot, think about this. Remember too that before the major canals were constructed the 1900s, the river received less than half the water it gets every time it rains today.
The aerials below were taken 6-13-17 by my husband Ed Lippisch and pilot Dave Stone. It is important to monitor the river all of the time so we can view changes.
“Rain stained” we are; please remember not to fertilize during the rainy season. The birds on Bird Island will appreciate it! (http://befloridian.org)
Canals draining water into SLR/IRL after rain events:
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.
WIKI 1949 Hurricane: https://en.wikipedia.org/wiki/1949_Florida_hurricane
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.

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 email@example.com
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.

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).

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.

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.
Blue-greens from Space
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.
