Some months ago, the original “River Warrior” Piper Cub was replaced with a Super Cub. Because the Super Cub is so much more powerful, more like a helicopter, it is much windier in the back of the plane, where I sit. I almost dropped my beloved iPhone, many times, before I gave up….
I have had to replace my lightweight and versatile iPhone with a “real” camera as the weight of the camera is stabilizing. Today, I share some of my other aerials of the St Lucie/IRL Region from 3-2-19, taken with this heavier camera. I thank my husband Ed for “giving me wings.” Over the coming months, as I adapt, we shall begin to document all of Florida’s east coast. First, here’s home!
Circling back over the IRL and US Sailing Center’s regatta, a beautiful sight!
The remaining photos are coming in for landing circling over the St Lucie at Roosevelt Bridge and developed lands…

“Say No to Lake O,” this is one of the rallying cries of the River Kidz. If only it were as easy as just saying “no.” According my numbers-man, my brother Todd, the “St Lucie River has taken in more than 86+ billion gallons this year, enough to put Stuart under 111 feet of water. This is only enough to take 6 inches off of the lake.” The west coast is taking most of the lake level reducing water and of course they are screaming “say no to Lake O” too.
Realistically, with the Army Corp of Engineers reporting the Lake level at 17.07, today, it will be a few more weeks of releases to get near or under 16 feet. A safer number for the dike and for the people who live in fear of it breeching. Not to mention the 525,000 of acres of protected sugarcane… http://w3.saj.usace.army.mil/h2o/reports.htm
I do believe the authorities are getting the message, though…so keep screaming. SAY NO TO LAKE O! For everyone!
I think our water culture is changing, and the government is being forced/inspired so they can get reelected and respected…. to improve our water/rivers situation. Just yesterday, I got an email about a woman whose Bascom Palmer doctor notes she has an eye infection in her cornea very possibly from “walking the bridge,” repeatedly over the St Lucie River.
I am not making this up.
These health issues are real. More and more people are realizing this. Lake O and other canal unfiltered pollution must halt.
It’s hard believe that we have taken 86+ billion gallons this year, enough to put Stuart under 111 feet of water. But this is only enough to take 6 inches off of the lake. The west coast is taking most of the lake level reducing water.
By the way, I have a new link of my Lake O Satellite imagery page that will actively pull up the last 7 days of low res images from all three satellites: St Lucie River Discharges Latest Lake O Satellite Imagery (http://www.thurlowpa.com/LakeOImagery/) Click on the “Terra/Aqua/Suomi Last 7 days icon”.

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…
“Eden,” the name says it all. Wouldn’t it be cool to say you lived in Eden?
Today there is a historic sign, but there is no longer a town. In 1879 “Eden” was named by Captain Thomas E. Richards who decided this spot along the high ridge of the Indian River would be a good place to grow pineapples. According to historian, Sandra Henderson Thurlow, “Richards felt he had arrived in a tropical paradise, and named his new home Eden.”
In Sandra’s book, “Historic Jensen and Eden on Florida’s Indian River,” she talks about how today’s Jensen Beach evolved from both the historic communities of Eden and Jensen, but over time, while Jensen had room to grow, Eden faded, as it was hemmed in by the wet, fragile ecosystem of the savannas. This marshy savannas system once stretched along the lagoon for over a hundred miles, but today, the only remnant lies right behind the lost town of Eden, and to the north and south of close-by extending lands.
These rare lands known today as Savannas Preserve State Park, “encompass more than 5,400 acres and stretch more the ten miles from Jensen Beach to Ft Pierce containing the largest, most ecologically intact stretch of freshwater marsh in southeast Florida.” Remarkable!
If you haven’t ever seen it, I can promise, “Eden awaits you…”
This past weekend, my husband Ed and I put on our wet weather gear, and walked from Jensen Beach Blvd to “west of Eden. ” It is amazing to have this treasure right in our own backyards, a study in plant and animal life that “used to be.” ~A study in what we can bring back, if we want to…

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.
Happy 17th Birthday to Chase! If you don’t already know him, Chase is one of Stuart’s leading sports fishermen, in any age category. This photo is of a recent catch of my favorite fish, the beautiful and unforgettable, “Silver King Tarpon.”
Since Chase was thirteen years old, when we ran into each other, he would share photos of his fishing expeditions. I always stood there, mouth wide open…”Are you kidding me?” I would ask. He would just smile with his wide, blue eyes saying it all:” THIS IS NO FISH STORY…
In 2015, Chase and I, together with many others tried to save a pigmy whale that had beached at Stuart. Chase loves the outdoors and has respect for all of the water’s creatures.
Yesterday, in Jensen, I ran into Chase celebrating his 17th birthday with family and friends.
Perhaps it is his mother’s wonderful name, “Cobia,” that inspires her son! 🙂
If you are a reader of my blog you know, the ancient, acrobatic, and historic tarpon is my favorite fish as it was the original sports fish of the St Lucie River/Indian River Lagoon, until its numbers were destroyed by canals, C-44, C-23, C-25 and C-25. Had these canals not been allowed to decimate our river, Tarpon would still be King, not the famous off-shore Sailfish….
Thank you Chase for sharing and inspiring us all! We know you have a great future ahead of you!!!! I can’t wait ’til you have your own show!!!!!!
For some stories there are no pictures, only your imagination…Today I will share a story brought to my attention by my mother in line with my recent interest in ponds.
It was September of 1924, Stuart was still part of Palm Beach County, and few people lived here. It was the “boom era” and residents were excited about building the future. But then it started raining, and raining, and raining…
By Edwin A Menninger, reprinted in the 1950 Anniversary of the Stuart News with my location references.
JUST WHAT WAS STUART LIKE 25 YEARS AGO? THE YEAR STUART ALMOST WASHED AWAY…
…We had just had four days of torrential rain. At one time it rained 36 inches in 36 hours. Stuart was flooded. The railroad tracks washed away at Rio. They washed away also just south of Salerno, and two FEC passenger trains carrying about 500 people were marooned in Stuart till the tracks could be rebuilt. The Vanderbuilts just happened to be on the train!…I published a special FLOOD EXTRA and sold 400 copies…the heavy rains made an enormous lake in th heart of Stuart. (It was before 4th Street (East Ocean) was graded and paved) and a huge lake stretched from the court house to the school.(Today’s Stuart Middle School and Ad. Buildings)
A small ditch to drain off the worst was dug from the lake’s edge (where W.V. King’s house now stands) (Across from Willie Gary’s office on Osceola today) to the St Lucie River; in an hour this became a raging torrent. Water ran so fast it dug a ditch 75 feet wide to the river, undermined houses nearby, threatened extensive damage before Curt Schroeder and his crew got things under control again. The ground was s waterlogged that drainage problems were difficult. Water stood across 4th Street (East Ocean) in deep, big ponds for more than a month in front of where John Demich now lives (today’s 5th and Cortez) and at the tennis court. The old hospital building was surrounded by water for weeks and physicians came and went in boats…
A raging torrent that dug a 75 foot ditch from East Ocean Blvd to the St Lucie River! Doctors going to the hospital in boats? Holy cow. That must have been something. How did they put back the land that washed out? Below I have tried to figure out where that area might have been…
In closing, hope you have enjoyed this week’s pond series. The message remains the same, Lake Okeechobee or a little pond on East Ocean Blvd. “Over drainage has consequences….”
Notes of location referred to in the 1924 article, by Sandra Thurlow, help to figure out location:
Mom, where is the King’s house?
The King house was Kay Norris’s parents’ house across from the Pelican Hotel (Willie Gary’s ) The corner of our church property where Mary’s Closet is today used to flood terribly. There was once a rectory there that had to be demolished because it flooded and was ruined. Uncle Dale could tell you all about that. The King house still stands on Osceola I believe. At one time it was Dr. Eckersley’s office.
2. Where was the Dumich house?
Dumich lived on 5th Street about where Cortez intersects it.
3. Mom, remined me about the flooding when I was a kid.
Think of the courthouse. As you probably remember Memorial Park was always flooding. When it was suggested for a site for the library years before, Mary Kanner, (Kanner Highway, Highway 76, is named after her Judge husband) said “I am not going to have the library built in that sometime lake.” The pond that was dug in front of where the Log Cabin was constructed, later became the Middle School Pond. Now, it too, has been made to disappear.
Notes of Edwin Menninger:
~Edwin A Menninger, The South Florida Developer, 1924
(Menninger purchased the weekly paper, South Florida Developer, in 1923, moving its publication headquarters to Stuart from Canal Point. In 1928 he bought the Stuart Daily News. This excerpt was reprinted in the 1950 Anniversary Edition of the Stuart News.) (This excerpt can also be found on page 453 of a History of Martin County.)
Thank you to my awesome brother Todd Thurlow who created this image after reading today’s blog post. He writes: “Hi Jacqui – If you want to see the 1924 lake, the FEMA flood maps show the low spot pretty well. Check thiis out:” ~Todd
Today’s blog post, created by my brother, Todd Thurlow, just totally blows my mind. His time-capsule flight through images of Google Earth, historic maps from 1850 and 1940, and an aerial from 1958, takes us on a journey through the extensive pond-land/wetland that used to be the area of Downtown Stuart and beyond. Today we all live here, most of us not even realizing what the land once was…this wetland now “magically” drains into the St Lucie River.
In Todd’s video you can see that Stuart Middle School actually is now sitting where an old pond used to be; there were ponds expanding and contracting with the rains in today’s Memorial Park; there were ponds in the areas of today’s County Courthouse; there were ponds scattered over today’s airport, Witham Field; there were extensive ponds along East Ocean Boulevard and Dolphin as featured in last Friday’s popular blog post. Yes, there little ponds just about everywhere!
Sometimes we think the wetlands are “out west” and they are, but years ago they were also here. I have to say am guilty of this too. When I came home after university in 1986 and just about everything was developed, once again, amnesia! Look, after you watch Todd’s video, and notice the drainage canals around Monterey Blvd., St Lucie Blvd, back by Kingswoods Condo, and on the edges of Witham Field and there are many more. Of course like the grates and drains in every parking lot, these canals drain into our ailing St Lucie River. Lake Okeechobee is the big toxic hammer but there is local destruction too…
She describes a 1958 aerial photograph that hangs in my law office. The photo is from my parent’s “Thurlow/Ruhnke” collection. I had used the photo for a Google Earth presentation for Stuart Heritage on May 8, 2012. http://www.stuartheritagemuseum.com/
This is a recording of maps and photographs used for part of that presentation: 1850s Government Land Office Plats, 1940 USDA aerials and the 1958 Thurlow/Ruhnke photo.
There is no sound or text overlays but here are a few features to note:
0:50 –What was called the “Stuart Middle School Pond”. We jumped in that pond on the last day of school to celebrate graduating from 8th grade. A few years ago the pond was filled in to make room for a new building.
1:00 – The end of Fourth Street (what is now called East Ocean Blvd). East Ocean Blvd. ended at the intersection of St. Lucie Blvd/ Oriole Ave. on the left (north) side and Dolphin Drive on the right (south) before it was extended to the “Bridges to the Sea”.
1:14 – The oblique aerial described in Jacqui’s blog. Note the building in the bottom right corner. That is the Broadway Service Center which still stands today. See https://goo.gl/iODQwU
1:47 –The Evan’s Crary Bridge (aka the Ten Cent Bridge) under construction in the background
2:24 – 1940 flyover of Dolphin Drive. Note the single building in the middle of nowhere. That residence is still standing on the corner of SE 6th Street and Flamingo Ave. According to the Martin County Property Appraiser, it was built in 1925, years before the photo was taken.
2:30 –The 1940 view before our current airport. The previous Krueger Airport was off of East Ocean Blvd. Dolphin Drive continued all the way from East Ocean Blvd. to St. Lucie Blvd. by the river. If you have ever taken the “back exit” from the Stuart Air Show onto St. Lucie Blvd, that still existing right-of-way is what used to be the other end of Dolphin Drive.
“Time Capsule Flights,” created by my brother, Todd Thurlow, has been a shared favorite on my blog since 2014. In these remarkable videos, Todd uses his legal and historical knowledge to create a living collage juxtaposing historic and modern-day images to achieve dramatic insights into watershed and land use changes in Florida over the past hundred years. These videos are a must for anyone wishing to understand our state’s history or working to restore its waters and lands in the future. You can access all of Todd’s videos here: http://maps.thethurlows.com.
“See that white strip just below the wetland? That is the extension of Flamingo Drive that skirts the pond behind the old car wash. They just dug a retention pond and conducted the water to it. All of that pineland is covered with condominiums today.” (Cedar Point, Vista Pines, and Kingswood)~ Sandra H. Thurlow
Today we drive over the Indian River Lagoon and St Lucie River surrounded by “civilization,” and forget that once it was once a wetland and pine forest full of wildlife. In the course of a lifetime, these things are long forgotten.
The above 1957 photograph hangs in my brother’s law office. When I visit him, I find myself staring at it for long periods of time. It is one of those rare photos that really puts things into perspective. The road construction through the wetlands, (note it going through the pond, and pine forest) was all taking place around the same time that the “Bridges to the Sea,” from Stuart to Sewall’s Point, and Sewall’s Point to Hutchinson Island, were completed. It’s amazing to see what the landscape once looked like. The road in the photograph, Fourth Street, was renamed “East Ocean Boulevard” in 1960, and is a major thoroughfare to the beaches today.
I remember early East Ocean Blvd, although it was already quite changed by the time I was born in 1964. My family lived at 109 Edgewood Drive in Stuart, a short distance away from these wetland ponds under development. I recall Scrub Jays in our back yard and feeding them peanuts. By 1974 the family moved across the river to Sewall’s Point “growing and improving” with the changing landscape.
By 1979, when I was fifteen years old, riding my bike over the bridge to Stuart to work at the Pelican Car Wash, the beautiful wetland pond had been relegated to a retention pond for run off. Over the next two decades, you didn’t see wetlands and ponds anymore, or wildlife, just condominiums, office buildings, and shopping plazas. The state four-laned East Ocean Boulevard and built higher bridges to the ocean too.
Believe it or not, the pond in the aerial is still located behind a gas station that used to be the car wash. It is not even a shadow of its former self. Two days ago, I drove by and noticed that there was an extensive algae bloom in the pond backed up to the parking lot and gas pumps; the water reflecting a sickly shade of green.
I sat there thinking about the long forgotten pond in the middle of East Ocean Boulevard in the photo I love in my brother’s office, wishing the developers had figured out a way to go around the pond. As the shortest distance between two points, over time, is not always a straight line.
Today, May 12th, at 9:45 A.M. Governor Rick Scott is scheduled to sign Senate President Joe Negron’s “Senate Bill 10” in of all places Clewiston. Clewiston is “America’s Sweetest Town” and the headquarters of U.S. Sugar Corporation…
According to the article in the Glades County Democrat announcing the signing: “Earlier this week Senate Bill 10, a move to secure funding for a water storage reservoir south of Lake Okeechobee was approved. In its amended form, Senate Bill 10 became a measure that we in the Glades could stand behind. The bill no longer stated that additional farmlands be taken out of production but rather the state would utilize the property that it already owns to create a reservoir with a much smaller footprint.”
Although I am scratching my head, you know what? Sometimes you just have to be happy for what you get, no matter where you get it. I am tremendously thankful to Governor Scott for signing the bill ~ although I do wish he had decided to sign it in Martin County since we’ve worked so hard to get it.
When I read the announcement officially last night, it got me thinking about Clewiston before I went to sleep. It brought back memories of 2013 and famed paddle boarder Justin Riney’s idea to hold the Sugarland Rally in Clewiston on September 1st, 2013 to unite the movement. This was one of the early rallies for the river during the devastation of the “Lost Summer.”
Since Governor Scott is going to sign in Clewiston I think it’s a good time to walk down memory lane and be proud of how far we’ve come and to get ready for how far we have to go! The point of the location of the Sugarland Rally was to “meet halfway.” Hopefully Governor Scott is thinking the same, in that Joe Negron helped us meet half way and we are all thankful.
Now let’s remember the past, enjoy today, and then take it to the finish line!
“The Sugarland Rally will unite the east and west coasts of Florida in a peaceful, historic demonstration to speak out against the pollution of our estuaries from Lake Okeechobee discharges. We support both immediate and long-term solutions, but ecosystems and communities along the St. Lucie and Caloosahatchee Estuaries are in crisis. We cannot afford to wait for ecological and economic collapse. We urge all stakeholders–especially local, state and federal governments–to act immediately. We chose Clewiston as a central location to unify east and west at Lake Okeechobee, the source that is polluting our estuaries, and because we believe Florida’s sugar industry can be part of the solution. Please don’t misinterpret our intentions–we are NOT holding a rally at Clewiston to protest or point fingers at “Big Sugar.” It’s quite the opposite, actually. We invite Florida’s powerful sugar industry to join us in crafting an immediate solution to the ecological and economic crisis caused by discharges from Lake Okeechobee.” (Press release from Justin Riney, Aug. 2013)
My husband’s flight yesterday over the Atlantic Ocean, St Lucie Inlet, and St Lucie River/Indian River Lagoon is beautiful. But look carefully and you will see a light-colored brownish plume at the mouth of the St Luice Inlet entering the ocean. Finally after months of drought, it has begun raining. And when it rains… (mind you C-44 connecting the St Lucie River to Lake Okeechobee is closed now) the re-directed run-off of waters from canals C-23, and C-24 of course still flow into our St Luice River/Indian River Lagoon.
These canals organized and built during the 1950s and 60s are part of the Central and South Florida Flood Project that the Army Corp built following the hurricane and extensive south Florida flooding of 1949. The run-off waters from these canals and the local watershed are what you see in today’s video.
As damaging as C-23 and C-24 are (they too must be reworked and redirected) they are not the damaging discharges from Lake Okeechobee that throw the St Lucie over the brink as in 2013 and especially 2016 when toxic algae covered extensive portions of the entire St Lucie.

Shoreline of Sewall’s Point, Tracy Barnes 6-25-16
(Photo mosaic from 2016 shows various photos by Dr Scott Kuhns, Rebecca Fatzinger, (wildlife) JTL/Ed Lippisch, pilot Dave Stone and others.)
In spite of the light brown plume, the short video flight from Jensen to Peck’s Lake shows blue waters near the inlet and mouth of the estuary as it should be, not black water. If Governor Scott does not veto the budget, the reservoir in years to come will help offset the Lake Okeechobee destruction and open the way to truly “send the water south.” #ThankyouJoeNegron
This is very exciting, but believe me, this is no time to let down your guard, as the fight for control of Florida’s waters has really just begun.
Senate Bill 10, the bill associated with Senate President Joe Negron and his goal to stop the damaging discharges of Lake Okeechobee to the St Lucie River and Caloosahatchee… my gosh, up and then down, and then up again…Why such a roller coaster ride?
The last time I went on a roller coaster ride was many years ago when I in my twenties and teaching German at Pensacola High School. I took my IB high school students and 14 visiting German exchange students to Six Flags. I got so sick on the ride that I had to sit on a bench the remainder of the day. The students? They loved it and went multiple times! Roller coasters are not fun for everyone. But one thing’s for sure, if you’re on the ride, and you feel sick, be assured that it will end, but when it hasn’t, hold on! This bill, this ride, won’t end for another month plus, as it has to be voted on by the full Senate and achieve a matching bill in the House….
Thus far, the bill has really gone “double-full-circle-upside down-roller-coaster” in that Stuart’s Dr Gary Goforth ( http://garygoforth.net) mentioned the many configurations available to achieve “the goal” during the January 11th 2017 meeting of the Senate Natural Resources Appropriations Committee. At this time he pointed out that some of those “loopy configurations” on his visual went back to CERP’s birth year of 2000 and the first goals the state and federal government had for an EAA reservoir!
You can watch Dr Goforth’s presentation and see his handout linked at the top of this post. Gosh, I kind of feel sick, yes, there have been so many changes and so many numbers… 60,000, 14,000, 360,000, 240,000, A-1, A-2, my head is spinning! There is so much back and forth! Yes there is, but goodness, you can’t say this isn’t exciting! The St Lucie River and Indian River Lagoon a roller coaster for the whole world to see! Personally, I am going to try NOT to sit out on the bench this time, how about you? 🙂
Here is a Senate staff summary of what part of the rollercoaster ride the bill is on today:
Establishes options for providing additional water storage south of Lake Okeechobee, including the:
o Everglades Agricultural Area (EAA) reservoir project with the goal of providing a minimum of 240,000 acre-feet of water storage; and
o C-51 reservoir project with the goal of providing approximately 60,000 acre-feet of water storage.
Authorizes the Board of Trustees of the Internal Improvement Trust Fund (TIITF) and the South Florida Water Management District (SFWMD) to negotiate the amendment or termination of leases on lands within the EAA for exchange or use for the EAA reservoir project.
Requires lease agreements relating to land in the EAA leased to the Prison Rehabilitative Industries and Diversified Enterprises, Inc., (PRIDE Enterprises) for an agricultural work program to be terminated in accordance with the lease terms.
Requires the SFWMD, upon the effective date of the act, to identify the lessees of the approximately 3,200 acres of land owned by the state or the district west of the A-2 parcel and east of the Miami Canal and the private property owners of the approximately 500 acres of land surrounded by such lands;
Requires the SFWMD, by July 31, 2017, to contact the lessors and landowners of such lands to express the SFWMD’s interest in acquiring the land through the purchase or exchange of lands or by the amendment or termination of lease agreements.

Robert Lord is President and C.E.O. of Martin Health Systems, formally known as Martin Memorial Hospital. “MHS” as it is known for short, is the long time top-employer for Martin County, and a respected and expanding health system. It has been located in Martin County for 75 years. (https://www.martinhealth.org) The origianl institution sits along the shores of the St Lucie River, near downtown Stuart and has grown into both south Stuart and St Lucie County. It is a literal “lifeblood” of our communtiy.
I have known and admired the Lord family since my childhood. Bobby Lord, Robert Lord’s father was a local celebrity in Stuart’s early days as he is a County & Western legend. (https://en.wikipedia.org/wiki/Bobby_Lord )I attended both elementary and middle school, and graduated from Martin County High School in 1982 with Robert’s younger brother, Cabot.
I cannot express how much it meant to me last Thursday to see “Robby” Lord, accomplished attorney, now President and C.E.O. of Martin Health Systems, in his position of leadership and influence, speak in support for Senate President Joe Negron and Senate Bill 10. A bill intended to purchase land south of Lake Okeechobee for a reservoir to begin what must happen to save our river: “clean and send more water south.”
Having known the Lord family all these years, I have followed Rob’s career, especially as my sister, Jenny, is physician recruiter, and has served the hospital loyally for almost 20 years.
So, Bravo Rob Lord! You have created a “hometown game-change,” and as we all know, it is not easy to speak up. There are tremendous pressures to conform and accept things as they are. Over the past few years, outside powers have moved into our area influencing and blurring the lines.
I believe that Rob’s speaking out will clear the blurred lines and change the playing field forever. There is no mistaking it. Lake Okeechobee’s discharges are a health issue and must be stopped. Our state and federal government can ignore this no longer in spite of the influences of power.
Excerpt from speech:
“…Good morning, my name is Rob Lord. I am President and C.E.O of Martin Health System .. I care deeply about the impact of Lake Okeechobee discharges on the estuaries. I grew up on the Indian River Lagoon. My family moved here in 1969. I have fished these water with my father, my grandfather, and my brother and nephews and nieces. No one values this eco-system more than my family. We watched it change. As CEO of Martin Health System this has been a significant challenge for us. This past year blue-green algae came to our community. We needed to post this sign in our emergency room. We treated this very much like we needed to treat the Ebola situation….”
Dr. Steven Parr, Director of Emergency Medicine at Tradition Medical Center noted there are studies occurring now to determine whether the toxins trigger certain diseases such as Alzheimer’s, Parkinson’s, and ALS also known as Lou Gherig’s disease.
As much as I romanticize my youth along the St Lucie River/Indian River Lagoon in the 1960s, 70s, and 80s, one thing I did not see were birds of prey. Populations had plummeted here and across our nation. The use of DDT, for mosquito control, especially, had drastically reduced bird populations. I truly do not recall even once seeing an osprey fly over the Indian River Lagoon when I was a kid….Hard to believe, isn’ it?
Today, forty years later, every single time I walk the Ernie Lyons Bridge to Hutchinson Island I see multiple ospreys sitting on light posts and diving like missiles into the shallow waters of the Indian River Lagoon. On the Roosevelt Bridge in Stuart there is a resident osprey I count on seeing each time. He sits on the railing completely unaffected by the stream of civilization passing by. Last week, while driving home from Belle Glade, I saw a bald eagle near the Dupuis Wildlife Management Area. “An eagle!” I exclaimed out loud pulling over my car to watch its unmistakable white head and magnificent wing span glide over the tops of the pine trees. “Amazing…” I thought to myself.
The point is, good things happen. Good things are happening now too, but like the birds of prey we may not see the difference until many years have passed. Have hope. Know your work is making a difference for our river and our environment. Things can change for the better. The osprey and the eagle, they are proof. When you see them, be inspired!
When I was kid growing up in Stuart, I remember seeing a lot of cottages. I loved these structures ~so simple, efficient, and adorable too. I remember cottages at Frances Langford’s Outrigger Resort just north of Sewall’s Point; I remember cottages in Rio along Dixie Highway; and I recall the cottages along Indian River Drive in Jensen at the old Pitchford Camp. Somehow the more run down they were, the cooler they appeared. A reminder of days long past before Martin County developed and we were all brainwashed of the need to build bigger houses and complicate our lives.
Today, when one hears the name “Pitchford,” one may envision a Martin County Commission embroiled in a decade of controversy, but this wasn’t always the case. In fact in the early 1900s the name “Pitchford” was a family name that defined “good times” of fishing, dancing, and playing shuffle board along the beautiful and healthy Indian River Lagoon.
Recently, I was invited by long time friend of my parents, Boo Lowery, to see his modern-day, old-fashioned, fish camp. Boo, himself, an “old-timer” is related to many of the early families of the Stuart area. Boo’s career as a respected contractor working closely with famed architect, Peter Jefferson, allowed him to become an expert in building, moving, and renovating homes.
In the 1980s when the cottages at Pitchford Camp were going to be demolished, Boo, who along with his wife Soo is a “lover of all things vintage” stepped in and saved five of the Pitchford Camp cottages. Over time, the little structures have been moved alongside land where a “borrow pit” (dug to build part of I-95) was located. This hole in the ground, today, is a serene pond in the middle of a pine forest, and a living museum housing the Pitchford cottages and of a way of life along our waterways that no longer exists.
It was so much fun going to Boo and Soo’s and today I am sharing some of my photos. While eating hush puppies and alligator, I told my husband, Ed, “I could live in one these cottages.” That I wanted to live in one of these cottages! He looked at me like I was out of my mind… Perhaps, he thinks I’m too soft and spoiled by “progress.” Maybe I’m dreaming, but I think I’d love it. I think I’d be as “happy as a clam…”
In any case, enjoy the photos of this very special place and thank you Boo and Soo for holding on to the old ways and for keeping our Indian River Lagoon history alive.
“Robert McClinton, “Doc, ” Pitchford was the only remaining Pitchford brother after Herbert’s death in 1988. When Doc died in December 2001, it was the end of an era. Doc tried to hold on to the old ways and was quite successful. The Pitchford holdings were like a time capsule surrounded by computer-age progress. Although most of the original Pitchford Camp cabins were demolished….”
Boo saved a few!

Today I share the second paper of guest, Geoffrey Norris Ph.D. I recently shared Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee.
I must admit, I hesitated publishing this second paper, “Sugarcane and Indians,” as I am sure some may interpret it as “politically incorrect.” I apologize to anyone who may, but I decided to print Dr Norris’ paper because the main message is important.
The message is:
“Is Sugar’s use of ripening stalks with “Roundup” feeding toxic algae blooms and why are lands/waters south of Lake Okeechobee “protected” while ours of the northern estuaries are not? “
You will learn something about this in Dr Norris’ paper below, and I thank him for sharing his work.
In closing, I believe we have something important to learn from history and the Native People of North America; I admire them. They are great warriors and respect Nature, the gift of our Creator. And in the case of the Miccosukee, they “never surrendered” and if I have anything to do with it, neither will we.
..”In the 1960s, I lived and worked as a petroleum exploration geologist in Tulsa, Oklahoma. Subsequently, I spent almost 40 years at the University of Toronto in teaching and research in geology…A geologist by training, I have a specialized knowledge of fossil algae, their ecology, morphology, and distribution. I have published hundreds of scientific papers on fossil algae and related topics.” ~Geoffrey Norris Ph.D.
Sugarcane and Indians
The area around Lake Okeechobee accounts for almost half the total production of sugarcane in the United States.
Sugarcane in south Florida is very needy of phosphorus and potassium fertilizers, but nitrogen fixed in the muck soils largely eliminates the need for extra nitrogen fertilizers.
Sugarcane also demands the use of the phosphorus-rich herbicide “Roundup” (glyphosate) several times each year. Firstly, in the fallow season (approximately May-September) to control weeds and allow the sugarcane underground rhizomes to regenerate. Secondly, as the new shoots come through in the Fall to continue weed control. Thirdly, during maturation and harvesting (October through March) glyphosate is applied to “chemically ripen” the sugarcane and improve sugar yields.
Land south of Lake Okeechobee could be used for storage and bio-cleansing of excess lake water. However, the 1997 water quality agreement between the Environmental Protection Agency and the Miccosukee Indians (aka Mikasuki, Miccosuki) states that phosphorus shall not be present in quantities greater than 10 parts per billion, and that no substance shall be present to stimulate algal growth and produce objectionable algal densities in the 300,000 acres of tribal lands in the Everglades south of Alligator Alley.
This legal agreement would suggest that Lake Okeechobee waters destined for southern storage must be cleaned to rigorous standards before discharge into southward flowing streams feeding the Everglades, at least near the Miccosukee tribal lands.
A case could be made for the sugar industry and related agriculture to “clean up its act” to mitigate the effects of heavy fertilizer and herbicide usage on the environment in general and on lake and stream waters in particular.
Sugarcane and Indians
First about nutrients and farm land and how much is planted in sugarcane.
Here are three maps that graphically answer the question about the extent of sugarcane plantations:
A couple of years ago I had the opportunity the fly over the area south of Lake Okeechobee in a light plane at about 1000ft altitude. The extent of the sugarcane is truly mind-boggling. Its plantations surround the entire southern perimeter of the Lake and reach to the horizon. Smaller plantations occur elsewhere around the Lake. It is a very big operation.
Now to the nutrients themselves. I had a great deal of difficulty finding precise information on how much fertilizer is applied per unit area. There were general articles that confirmed that sugarcane is very needy of nitrogen, phosphorus, and potassium fertilizers together with other elements. It is after all a giant grass, so just think how much stuff you have to put on your own lawn to make it grow green! Apparently, in the south Florida area the need to apply nitrogen fertilizer to sugar cane is not so critical because the mucky soils generate their own nitrates through soil microbial activity. However, phosphates must be applied as fertilizer for sugarcane at various times of the year together with potassium etc. But actual numbers were hard to come by, other than that sugarcane is voracious for fertilizers. This is when I stumbled upon some marvellous work that the U.S. Geological Survey has been doing on the extent and the total quantitates of pesticides being applied to farmland across USA. I used their maps of glyphosate (Roundup) as what I thought might be a reasonable proxy for phosphate fertilizer. In other words, if you use Roundup as a weedkiller on crops, then very likely you will be using fertilizer as well. It turns out I was right and I was wrong! First take a look at this summary map for two separate years, 1992 being the earliest year available in this USGS study:
Details are difficult to see in these summary maps but the originals are much clearer. The area around Lake Okeechobee was already in 1992 applying large amounts of glyphosate, and this intensified in succeeding years. What I didn’t understand was why the sugarcane fields should be so needy of weedkiller – fertilizers OK, but why so much weedkiller? It would seem that 25% of the cost of sugar production is due to heavy nutrient need (up to 75 lbs phosphate per acre, with 400,000 acres in sugarcane in south Florida). But weedkiller. Then I dug deeper following your email comments and found out why. Indeed glyphosate is used at least three ways on sugarcane as follows:
Firstly, during the fallow season (approx. May-September 2016) following harvesting, glyphosate is applied to control weeds which would otherwise grow up and choke out the underground cane sugar rhizomes left in the ground to regenerate as the next crop.
Secondly, glyphosate application continues in different amounts as the new shoots come through in the Fall. This is tricky because glyphosate kills just about anything that is green, but careful control can kill the young weeds while not harming – at least not very much – the young sugarcane shoots. Other herbicides are also involved but glyphosate is the big one.
Thirdly, the sugarcane matures and is harvested in the winter months at various times from October through March. During this time the stem of the sugarcane ripens and becomes rich in sugar (sucrose) prior to going to the mill. Astonishingly (to me anyway) it has been found that about a month or two prior to harvesting, another application of glyphosate will help ripen and enrich the crop with significantly more sugar. This process is called “chemical ripening”. Other chemicals can be involved but glyphosate is a popular choice (it got cheaper once Monsanto’s patent expired in the year 2000).
So yes, I think cane sugar farming is being pursued intensively, but I’m not sure how it can be stopped. Its effects on Lake O could be mitigated as discussed in my previous document but stopping an entire industry would be almost impossible to my mind. Cleaning up the sugar industry might be a more realistic aim.
Change of land usage and water flow.
It would be nice to think that Lake Okeechobee water could be redirected southwards along its original historic course on its way to the Everglades. Here’s a graphic of how things used to be:
For thousands of years, water drained from Lake O through a wide series of shallow tributaries and interconnected lakes to the Everglades. It’s unlikely that this could be recreated but certainly use of land south of the Lake for water transport and storage and bio-cleansing of some sort or another would be an improvement. However, it would seem that this is unlikely given the actions of the U.S. Environmental Protection Agency and its agreement in 1997 re the Clean Water Act with the Miccosukee Indians, a tribe which occupies part of the Everglades.
This agreement set out comprehensively water quality standards for the Tribes drinking water, wildlife habitat water, and recreational water (boating, swimming etc). In particular, Section 3 reads:
MICCOSUKEE ENVIRONMENTAL PROTECTION CODE
SECTION 3. Tribal Water Quality Standards
The following minimum water quality criteria shall apply to all surface waters of the Miccosukee Tribe of Indians of Florida unless those water bodies are designated with higher or stricter water quality standards. Stricter standards for a given water body shall supersede these general Water Quality Standards. These standards shall provide a legal basis for including whole effluent toxicity requirements in all federally issued permits.
(there follows a list of 16 physical, biological, and toxicological conditions of which these two are particularly germane):
E. NUISANCE CONDITIONS: Plant nutrients or other substances stimulating algal growth, from other than natural causes, shall not be present in concentrations that produce objectionable algal densities or nuisance aquatic vegetation, or that result in a dominance of nuisance species instream, or that cause nuisance conditions in any other fashion. Phosphorus and nitrogen concentrations shall not be permitted to reach levels which result in man-induced eutrophication problems. Total phosphorus shall not exceed 10 parts per billion in Class III-A waters. In Class III-B waters, total phosphorous discharges shall not be made which result in undesirable aquatic life effects or which result in chronic or acute toxicity to aquatic life.
N. NUTRIENTS: In no case shall nutrient concentrations of Tribal Class I or Class III-A surface waters be altered so as to cause an imbalance in natural populations of aquatic flora or fauna. Total phosphorus concentrations shall not exceed 10 parts per billion in Class III-A waters. In Class III-B waters, nutrients shall not be discharged which result in undesirable aquatic life effects or which result in chronic or acute toxicity to aquatic life.
So what this and other sections of agreement mean is that nutrient-rich water from Lake Okeechobee must be cleaned to rigorous standards before discharge into southward flowing streams feeding the Everglades. So bio-cleansing within the Everglades – or at least near the Miccosukee tribal lands (about 300,000 acres in the vicinity of the Tamiami Trail and Alligator Alley) is not a possibility within this legal framework.
However what’s good for the goose is surely good for the gander. I looked into the history of the Miccosukee Indians, and it would seem they are only fairly recent arrivals in Florida, arriving about the same time as Stuart was being settled. The Miccosukee appear to have originated in what is now Georgia and then migrated south to north Florida where they became entwined with the Seminoles. After the Seminole wars of the 19th century they migrated to central Florida in the late 1800’s and then decided to disentwine themselves from the Seminoles as a culturally distinct society. They appear to have seen an opportunity during the construction of the Tamiami Trail in the first quarter of the 20th century and migrated further south and became embedded in the adjacent Everglades. First Florida (1957) then federally (1962) they became recognized as a tribe distinct from the Seminoles.
Meanwhile in th early 20th century, as the migrant Miccosuki Indians were settling down in their new home in the Everglades as “Trail Indians”, Stuart was incorporated as a town (1914) then a city (1925) after being settled by migrant northerners about half a century earlier. Total population of Stuart is now about 16,000.
640 migrant Indians – how many are fishing and frogging? 16,000 migrant non-Indian northerners – how many lives and livings are being disrupted by ruined beaches and waterfronts?
the Indians pushed for a great deal from EPA and got it. So now a total of about 640 Miccosukee (Mikasuki) Indians (some now living in Miami-Dade and not the Everglades) can pursue their supposedly traditional way of life (fishing, frogging, subsistence agriculture) plus gaming resorts and casinos and tobacco shops – while many of the 151,000 citizens of Martin County are prevented from pursuing their traditional way of life. Surely our waters (habitat, recreational, drinking) should be subject to the same rigorous standards as laid down by the EPA/Clean Water Act for the people living in the Everglades.
We are all equal – as George Orwell said – but some are more equal than others. Well, so it seems. What do you think?
Writing my blog allows me to meet many interesting people. Recently, fellow Sewall’s Point resident, and active Vietnam Veterans of America member, Mr. Frank Tidikus, introduced me to Canadian and part-time Martin County resident, Professor Geoffrey Norris who is a geologist and algae fossil specialist with a long career at the University of Toronto.
Professor Norris, his wife, and I met at the Prawnbroker and had a lovely exchange. Dr Norris describes himself as such…
...In the 1960s, I lived and worked as a petroleum exploration geologist in Tulsa, Oklahoma. Subsequently, I spent almost 40 years at the University of Toronto in teaching and research in geology…A geologist by training, I have a specialized knowledge of fossil algae, their ecology, morphology, and distribution. I have published hundreds of scientific papers on fossil algae and related topics…
Professor Norris shared two papers composed for his property association at Indian River Plantation on Hutchinson Island along the Indian River Lagoon during the 2016 toxic algae extravaganza. Today, I will share the first entitled: “Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee.” His second, specifically on Sugarcane, I will provide next week.
Professor Norris’ summary and full paper is below. It is excellent in that it is able to relay complex subjects to the everyday reader interested in water quality and improving the plight of our St Lucie River/Indian River Lagoon.
What is most amazing to me are his comments on glyphosate, most famous for being the active ingredient in Roundup, but now used under many names. Sometimes I hear people screaming so much about Roundup that I tune it out, but Professor Norris’ observations really got to me.
He notes that glyphosate, used excessively in agriculture production around south and central Florida may actually “feed”cyanobacteria (toxic blue-green algae blooms). Also mind-blowing are Professor Norris’ insights into the reproduction of the hungry and ancient cyanobacteria that reproduces through binary fission (copying itself) “producing endless clones” “with no dissipation of mutant genes as a checks and balance to adaptation…”
Well, enjoy the reading the paper. And know, together we are making a difference!
Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee
This report provides basic information on blue-green “algae” and explains that they are actually bacteria (cyanobacteria). These blue-green bacteria form blooms in Lake Okeechobee that in turn are released by the Army Corps of Engineers into canals and estuaries of south Florida.
The blue-green bacteria grow by using sunlight as an energy source to synthesize elements from the water into more complex compounds used in their cells. When important nutrients such as phosphorus and nitrogen are present in excess, the bacteria multiply rapidly and accumulate as highly concentrated masses of cells, called blooms.
Blue-green bacteria can synthesize nitrates from atmospheric nitrogen, but also need phosphorus dissolved in water to survive and thrive. If phosphorus is scarce in the water, this limits the growth of the bacteria. If it is abundant, blooms can be triggered.
Run-off and back pumping into Lake Okeechobee from surrounding Everglades agricultural lands and upstream from the Kissimmee River watershed is suspected of providing a potential abundant source of phosphorus for blue-green bacteria, in phosphate-rich fertilizers and herbicides such as Roundup (glyphosate).
Glyphosate (2-[(phosphonomethyl)amino]acetic acid) is of particular concern, since it has been used heavily in the agricultural areas around Lake Okeechobee and upstream in the Kissimmee River watershed for at least 25 years. Glyphosate provides a source of phosphorus for blue-green bacteria and recent research by others suggest that glyphosate enhances the growth of blue-green bacteria, which become tolerant and absorb glyphosate directly.
The blue-green bacterial blooms released into the St Lucie Estuary (principally Microcystis) are formed in freshwater but appear to be tolerant of dilute salinities, and recent research suggests can build up resistance to increased salinities such as are found in estuarine waters.
Blue-green algal blooms in the lakes, rivers, and marine waters of south Florida surrounding Lake Okeechobee
I am a property owner in Stuart, Florida and have been alarmed – along with many others – at the spread of blue-green algae (aka cyanobacteria) into the St Lucie River and adjacent areas by water releases from Lake Okeechobee. There has been much publicity and calls for action over the years but very little appears to have been done to solve this long-standing problem at any level of government, until very recently. Now, a State of Emergency has been declared by the Governor of Florida. Recent initiatives, following public meetings in Martin County thanks to the Board of County Commissioners, have been undertaken by Florida Representative Gayle Harrell and Senator Joe Negron and their colleagues in association with Senators Marco Rubio and Bill Nelson and Rep. Patrick Murphy to urge the Army Corps of Engineers to stop immediately the nutrient-laden discharges from Lake Okeechobee.
Although I am a property owner and tax payer in Martin County, I am also a Canadian snowbird and therefore do not have a vote, which is a little constraining when trying to influence political decisions. Therefore, I decided to put my energies into assessing what is known about the current situation of the blue-green blooms. I am a geologist by training and I do have a specialized knowledge in particular of fossil algae that have been extremely important in oil and gas exploration over the decades gone by. I am not a biologist but I do have some knowledge of the literature on algae – their ecology, morphology and distribution in various environments. I have published hundreds of scientific papers on fossil algae and related topics and hope that the following – largely based on biological and agricultural literature – will pass muster.
In the following presentation my aims are twofold:
Firstly, to try and answer commonly asked questions about blue green algae (which are actually bacteria) that might be helpful in clarifying some of the technicalities of a complex subject.
Secondly, to highlight what to my mind is the ultimate cause of the blue-green outbreak: that is, the heavy application of phosphate-bearing fertilizers and herbicides around Lake Okeechobee together with back pumping of agricultural run-off into the Lake. In particular I believe that the well-known weed killer glyphosate (e.g. Roundup) may be implicated as a major contributor to the problem. South Florida and somewhat later Central Florida became major users of Roundup in the early 1990s, long before its popularity spread north into the corn and bean belt.
Feel free to pass this article on to others. I would welcome comments by email at firstname.lastname@example.org
What are blue-green algae?
Well, for starters they are not actually algae at all. They were discovered in the 19th century by biologists using newly invented high-powered microscopes. They noticed a variety of microorganisms living in water, some of them with green pigments in the cells that allowed photosynthesis to occur, similar to the well-known photosynthesis occurring in the much larger land plants and driven by chlorophyll. But they were much simpler in organization than the large land plants so were called “algae” (singular alga, from the Latin word for seaweed). Some of these microorganisms contain a rather different bluish pigment and were therefore referred to as “blue-green”, and in these early days were judged nevertheless to be algae – hence blue-green algae.
It was only later that biologists realized that the blue-green microorganisms were crucially different from algae because they had no nucleus in the cell and their pigment was not organized into a “blob” within the cell like most other algae. In the scientific literature they are now regarded as bacteria and the blue-greens are referred to as cyanobacteria – that is, photosynthetic bacteria that use a blue-green pigment to facilitate the use of the sun’s energy to produce organic compounds needed by these organisms.
It is important to understand this difference between the blue-green cyanobacteria on the one hand and the “true” algae on the other. I will come back to the difference between bacteria and algae later, and how this impacts on bloom formation.
Meanwhile, the term “blue-green algae” has gained traction in the news media and is now widely understood to be implicated in the blooms of microorganisms that occur from time to time in lakes and rivers in Florida and elsewhere. I will use either of the terms “blue-green algae” or “cyanobacteria” depending on the context, or just the neutral term “blue-greens”. But remember they are actually bacteria.
What are algal blooms?
An algal bloom is the result of rapid increase or accumulation of algae in a body of water. They can occur in freshwater (lakes, rivers) or in marine water (estuaries, lagoons, coastal embayments). Different types of algae (including the blue-green cyanobacteria) produce different blooms characterized by green, bluish, yellow, brown or red colors. The density of pigmented cells in a bloom is enormous, and measured in the hundreds of thousands to billions of cells per liter (1 liter is almost a quart) depending on the species.
Blooms can be quite localized and appear as a streak on the water or can be very large and visible from space, such as the algal blooms that occur from time to time in Lake Erie and measure tens to hundreds of miles in extent. The recent blue-green algal bloom in Lake Okeechobee was reported to be more than 30 square miles in extent.
What causes blooms?
Blooms occur naturally when the water contains an excess of nutrients such as phosphorus and other compounds. This causes an increase in the growth of algae leading to very high concentrations of cells that become visible as colored streaks and patches in the water. Other factors involved in triggering algal blooms include temperature changes, sunlight intensity, changes in water chemistry and changes in water currents.
What are the red tides that occur in Florida?
A red tide is just another name for a bloom of “true” algae in marine water, and in this case a particular algal group called dinoflagellates. Red tides can be red but more often occur as greenish or yellowish colored water in the coastal areas of Florida. The term “harmful algal bloom” is often preferred in referring to these dinoflagellate blooms that do indeed harm wildlife and human life in different ways e.g. toxic shellfish poisoning; respiratory illness; mass fish kills.
So what caused the blue-green algal blooms in Lake Okeechobee?
First, it is important to understand that blue green algae are uniquely different. Not only are they photosynthetic bacteria but they are also capable of manufacturing their own supply of nitrates from nitrogen in the atmosphere, one of their crucial nutritional requirements. So the blue-greens have plenty of nitrogen to live on but they also need other important elements and compounds to thrive. One of these is phosphorus, which often occurs naturally in water in trace amounts as phosphates. If phosphorus is scarce, then this limits the growth of the blue-greens even though they have potentially a lot of nitrates available. The amount of phosphorus available becomes a limiting factor for growth of the blue-green algae. If phosphorus becomes more abundant in the water, then the blue-green algae thrive and multiply until they become visible as a bloom. It is believed that high phosphorus concentrations in Lake Okeechobee are capable of triggering blue-green algal blooms.
So where did the phosphorus come from in Lake Okeechobee?
Lake Okeechobee is surrounded by agricultural land that is being intensively farmed. Run-off from the farmland appears to be entering Lake Okeechobee, and this includes various phosphate-rich fertilizers and herbicides such as Roundup (glyphosate).
But Lake Okeechobee water levels are higher than the surrounding plain. How can run-off into the Lake happen?
Well, firstly, Lake Okeechobee and the surrounding farmland share a common water table. Transfer of minerals and soluble organic compounds can occur through the groundwater. But probably more importantly, until recently it was common farming practice to back pump excess run-off water from the agricultural land into Lake Okeechobee. Almost certainly this had led to the accumulation of phosphorus and other nutrients in the Lake as well as unused agricultural chemicals. Aerial transmission into the Lake from crop dusting is also possible.
So now that back pumping has been discontinued will this solve the problem?
Not really, because although farmers now are not allowed to back pump into the Lake, the South Florida Water Management District has responsibility to alleviate the threat of flooding. They can – and do – back pump surface water from the surrounding land into Lake Okeechobee, if excessive rainfall conditions threaten to flood the communities around the Lake. Rainwater running off the agricultural land will still contain phosphorus and other compounds derived from fertilizers. Furthermore, from time to time the Army Corps of Engineers controls the level of Lake Okeechobee by releases of lake water into the canals, which in turn feed into the estuaries around Stuart and other coastal communities.
Are there any other agricultural products that are contributing to the appearance of blue-green algal blooms?
Yes, there is one in particular that is of great concern. Glyphosate is the active ingredient in the well-known weed killer Roundup. It is used intensively by farmers over much of North America. South Florida is one of the areas where it is being used very heavily in agriculture, and has been since at least 1992 (the earliest available data). A little further to the north, Central Florida’s usage of glyphosate surged in 1993 and continued until 2013 (the last available data) and may also be a source of glyphosate in Lake Okeechobee but originating further upstream in the Kissimmee River watershed and its interconnected lakes.
Glyphosate is an organic compound with phosphorus as an important component as well as nitrogen in its chemical make-up. It was invented by Monsanto chemists, brought to market in 1974, and its chemical name is N-(phosphonomethyl)glycine (aka 2-[(phosphonomethyl)amino]acetic acid) – glyphosate for short and much more easily remembered. Monsanto’s patent on glyphosate expired in 2000 and since then it has been manufactured by dozens of companies with a significant drop in price and therefore increasing popularity with farmers. In 2007 it became the most-used herbicide in agriculture in USA. It works as a weed killer by inhibiting the production of certain plant amino acids and enzymes. After it has done its deadly work, some of it can break down in the soil into simpler molecules of carbon, hydrogen, oxygen, nitrogen and phosphorus. Excess glyphosate can run off into water, particularly at peak farming times. Its use has been expanding in the agricultural sector by about 20% per year for the last several years.
So far, so good. It kills most green plants, if that is what you want. I personally use it to kill poison ivy on my property. Unfortunately, it has become apparent through a number of recent laboratory-based studies that glyphosate does not act as a killer for some blue-green algae, aka cyanobacteria. Firstly, the blue-greens love the phosphorus in glyphosate or its degradation products, which otherwise is a limiting factor in their survival. They thrive on increased phosphorus. Secondly and more insidiously, recent research has indicated that glyphosate actually enhances the growth of blue-greens. The blue-greens apparently have the ability to absorb glyphosate directly from the water and some are tolerant to it or become adapted to it by rare genetic mutations.
OK, but rare genetic mutations are just that – rare! So what?
Well, you remember that blue-greens are actually bacteria, not true algae. As such their genetic material is distributed throughout the cell, and they reproduce by binary fission producing endless clones. There is no “mix-and-matching” of chromosomes and genes such as occur in nucleated organisms using sexual reproduction that tends to dissipate the effects of mutant genes. Once a cyanobacterium has undergone a mutation, that mutant gene is replicated again and again as the cell divides. It produces clones of the mutant cell, and if that mutant has an advantage (such as resistance to or affinity for glyphosate), it will rapidly spread.
A more familiar example is the recent rise to prominence of so-called superbugs that are resistant to antibiotics. Human infections are often related to bacteria that enter the body, and are treated by the intake of prescribed antibiotics as a course of treatment for a number of days. If the antibiotics are not taken for an adequate period of time, the residual bacterial population includes mutants that resist the drug in question, and in turn that drug becomes less and less effective against new infections. This way a superbug is created e.g. MRSA (methicillin-resistant Staphylococcus aureus). So think of the blue-greens as bacteria (which they are) and glyphosate as an antibiotic (which it is). Those blue-green cyanobacteria that survive the glyphosate thrive as mutants and have the capacity to spread widely.
Do blue-green blooms last forever?
No. Eventually the blue-green bloom uses up available resources and requires more nutrients than are available leading to a decline in the number of cells in the water column. Also in temperate climates, the onset of winter temperatures can put an end to algal blooming for that season.
Then what happens?
The blue-green cells die off and sink to the bottom of the lake or estuary. Other bacteria move in and use the debris from the dead blue-greens as a source of carbon, and use oxygen in the water to fuel their own growth. This in turn leads to oxygen depletion that can be very severe. Without oxygen in the water, normal aquatic life becomes impossible and a dead zone is created: fish move away, and other organisms die that can’t move into more oxygen-rich environments.
How many blue-green algae/cyanobacteria exist?
About 2500 living species have been described in the literature but probably double or treble that number exist and await discovery and description. They have a very long geological history. Fossilized blue-greens have been discovered in rocks 3.5 billion years old.
How many are harmful?
Only a dozen or so species are actually harmful when they form blue-green blooms and emit toxic substances. In the recent outbreak, Microcystis aeruginosa has been identified as a bloom-forming cyanobacterium together with a couple of others.
So which blue-greens are responsible for the Lake Okeechobee and St Lucie River blooms?
The Florida Dept of Environmental Protection (DEP) took a number of samples from sites in Martin County and adjacent areas from Late May to Late June 2016 and the results are available at their website:
Most samples are reported as “mixed algae; no dominant species in the sample”, but a few are reported with more detail (numbers are depth in meters):
St. Lucie River, Central Marine Marina (N 27° 12′ 55″, W -80° 15′ 18″)
Dominant taxon: Microcystis aeruginosa
Dire Point Canal (N 27° 12′ 24.47″, W -80° 16′ 16.90″)
mixed algae; no dominant species in sample though specks of Microcystis aeruginosa present.
SE Harbor Pointe Dr. (N 27° 12′ 12.44″, W -80° 12′ 44.77″)
mixed algae; no dominant species in sample though specks of Microcystis aeruginosa present.
C-44 and S. Fork Mouth (N 27° 7′ 46.13″, W -80° 15′ 58.02″)
mixed algae; no dominant species in sample though specks of Microcystis aeruginosa present.
S-80 (N 27° 06′ 41.87″, W -80° 17′ 06.08″)
Dominant taxon: Planktolyngbya limnetica
Lake Okeechobee – Port Mayaca S 308 C Upstream Lake Side
N 26° 59′ 6″
W -80° 37′ 16.5″
Dominant: Microcystis aeruginosa
Lake Okeechobee near Channel Marker 9B
N 26° 46′ 36.6954″
W -80° 54′ 8.676″
Co-dominant taxa: Microcystis aeruginosa and Dolichospermum circinalis
Clearly, Microcystis appears to be important in several blooms, but quantitative and qualitative data are not provided for the majority of samples, making further evaluation impossible at this time. Dolichospermum (aka Anabaena) is a well known blue-green that produces nerve toxins and liver-damaging toxins, as does Microcystis. Planktolyngbya limnetica is another well known toxic blue-green.
How adequate has the sampling and analysis program by DEP been?
It is difficult to say for sure, since DEP only provides results of their program, not the sampling and analytical strategies themselves. However, from what can be gleaned from their website it would seem that during the month of June 2016 DEP collected 24 samples from 7 counties (Martin, Palm Beach, St Lucie, Lee, Charlotte, Hendry, Glades) over a 29 day period, covering a transect from the Atlantic coast to the Gulf of Mexico (Stuart/Palm Beach to Fort Myers). Of those 24 samples, 83% were reported “mixed algae; no dominant species in the sample” without further details. I would judge this to be a token response to what is clearly a major emergency. The analytical results appear to be lackluster to judge from details available on the website. No doubt DEP activities are constrained by their budget, but the lack of urgency in attempting to characterize these blooms is disappointing at best and may eventually be judged negligent to some degree.
What is known about Microcystis aeruginosa?
Quite a lot. It is the most common harmful algal bloom-forming species in freshwater. The cells are tiny but colonies can be macroscopic in size and contain gas vesicles that allow the colonies to be buoyant and float to the surface of the lake. It produces both neurotoxins and hepatotoxins that contaminate the water and have been known to kill dogs, other large animals and livestock in general that drink the polluted water. The toxins may be carcinogenic. Microcystis has a drastic effect on dissolved oxygen in the water that can lead to mass fish kills.
Can blue-green algae live in salt water?
This depends on the species. Many truly marine blue-greens are known in seas and oceans where they play an important role in nitrogen fixation and are important components of the marine ecosystem. In the case of Stuart and the St Lucie inlet and estuary, these natural estuarine waters have been diluted and/or replaced by fresher water discharges from Lake Okeechobee as shown in recent Florida Oceanographic Society water quality reports:
In turn this has allowed freshwater blue-greens such as Microcystis to establish colonies and blooms in areas that otherwise would support more saline organisms. So, for example, on June 30th 2016, the north and south forks of the St Lucie River, the St lucie River adjacent to Sewells Point, and the Manatee Pocket were reporting salinity values in the range of zero to 13 parts per thousand, areas which otherwise would be in the range of 15 to 30 parts per thousand. Hence some of these diluted saline waters can now support freshwater blue-greens.
Alarmingly, recent laboratory-based research has shown that some blue-greens – such as Microcystis – can build up resistance to increased salinity and, therefore, if this happens in the natural habitat can expand their range from freshwater to higher salinities.
What can be done to improve the situation?
If you have a vote at any level of government, contact your elected politicians to highlight the urgent nature of the blue-green blooms and to bring pressure to bear to use available resources to solve the matter.
Stop the back pumping of run-off water by anyone into Lake Okeechobee.
Curtail the heavy application of phosphorus-rich agricultural chemicals in farmland surrounding Lake Okeechobee.
In particular, request a thorough scientific investigation into the effects of glyphosate (Roundup) on blue-green algae (cyanobacteria) and their blooms.
In the long run, demand that the dike surrounding Lake Okeechobee be rebuilt with a view to diverting southwards the impounded waters back into the Everglades.
