Simple Version, Canal Network of SF w/Historic Imagery 1940-53, SFWMD

Current Canal Network of SF w/Historic Imagery 1940-1953 Map (Simple Version), SFWMD, created by supervisor of Geospatial Mapping, Dr Ken Chen, and his team: Lexie Hoffart, Nicole Miller, and Erika Moylan.

~Today’s map has almost the same name as July 11, 2020’s shared map, but it is “simple,” as the 298 drainage districts are not marked. To best view this image go to South Florida Water Management District’s Featured Map Gallery, click on the image, and then export the PDF to your desktop. An easy way is to link here to the image entitled SFWMD Current Canal Network with 1940-1953 Historic Images Simple Version  (2nd row, 3rd to right) then go to “File” and “Export as a PDF.”

Once downloaded to you desktop, you can zoom in and move up and down wherever you wish to go. North, south, east, west, central. What will you see? You will perceive the modern mapped canal network of South Florida atop hundreds of historic aerial photographs that have been stitched together. These maps are the first of their kind. 

This image gives us a clear idea of what canals drain South Florida. I don’t think ever in one place has this information been so visually available.

I will use the east coast of Florida to zoom into with screen shots for examples, as this is my home. Later, hopefully, you can use your zoom feature as described at the beginning of this blog post to downloaded the map as a  PDF for an even closer view. It will blow you away! 

In the images below, from north to south, we see St Lucie; Martin; Palm Beach; Broward; and Miami-Dade Counties with in the footprint of the  Central and South Florida Plan, now managed by the South Florida Water Management District. Mind you many of these canals in the map pre-date the SFWMD. 

Oh my gosh! Look at all these canals! Look at the wetland images they rest upon. Most children grow up today not even knowing…

The canals are almost everywhere draining what was once of the largest wetlands in the world. Think of all the animals that once roamed and swam here. According to Mark Perry, CEO of Florida Oceanographic, through these canals approximately  1.7 million gallons of fresh water a day is drained to tide.

Kind of weird isn’t it. Like we are living on a squeezed out sponge. Looking at this map makes me want to rethink Florida. How about you?

To understand the creation and complexity of the maps I am including the following words of Dr Ken Chen  Ph.D., GISP, Supervisor, Geospatial Mapping Services UnitInformation Technology Bureau, South Florida Water Management District. I had asked him to describe what was entailed with the historic imaging. Thank you to Dr Chen and Team whose talent, research, and time made these maps possible. 

  1. Historical aerials (1940 – 1953)

“Sources of historical aerials, especially 1940s and 1950s, are very scarce, especially for such a large area in South Florida. Therefore our focus was to get whatever we could find online regardless cloud cover or quality of images. As you know, all of those old images were recorded in an analog format (i.e. film or paper), instead of digital. Some (maybe all) of those films/paper images were later scanned and saved to a digital format and made available online. Scanning usually results in loss of imagery quality. For this canal map project, we were fortunately able to locate aerial index images (I would call them aerials index panels), after weeks of online research including data download and review. Each index panel displays a group of aerials in sequence over a specific area. For instance, say 200 images from #1 to #200 over an entire county. These index panels are usually used for aerial imagery management and archival purposes, just like a library index card for images. There is no information at all regarding how those index panels were created, but they are seemingly made via camera shooting or scanning of a group of stacked paper images or positive films. The index panels are simple graphics or pictures without any geospatial information, such as projection, coordinate system etc. The first step to process these index panels, prior to mosaicking, was to geo-rectify and inject geospatial information into the images. To do so staff needed to identify ground control points. It’s very challenging to identify those points in those very old images due to lack of apparent landmarks, e.g. road intersections. This is particularly difficult in the middle of nowhere across the vast wetlands in 1940s-1950s. So staff tried to use a very few of the intersections between rivers, canals and a few major roads to geo-rectify the panels and assigned appropriate geospatial information into them to make them georeferenced images. Then staff clipped each panel image to trim out the white or black edges before stitching all of them together for the majority of south Florida.

The original aerials were collected by the U.S. Dept of Agriculture. The aerials index panels were obtained from the Univ. of Florida’s Imagery Library. One thing to note – it’s very evident that there are strong image vignetting effects in the old aerials – bright in the center and getting darker toward the edges. That is an inherent optical artifact in the analog images and can not be corrected during the post processing.

This may be more than you asked for. I’m not sure if I have explained this clearly. To summarize it, this process can be simply illustrated in the following format:

Online search of available sources of data -> data download and review to accept or reject -> identify ground control points (GCP) in prep for image processing -> Using GCPs to georectify the index panels -> inject geospatial information into the panel pictures to make them georeferenced images -> remove the white/black edges -> Mosaick all georectified index panel images -> clip the mosaic to the district’s boundaries before use in the maps.

I forgot to mention the number of historical aerials we used to create the historical mosaic. We used totally 84 aerial index panels. Each panel consists of roughly 50+ to 200+ individual aerials, depending upon the geographic area each panel covers. I can’t get the exact number of aerials, my best guess the number would be ~7,000+-12,000.”

Color-Coded Maps – Help Us to Understand the Flow of Lake O

MAP 1.

New maps denoting volumes in 1000 acre feet as presented by John Mitnick P.E., SFWMD – please note for readability, slides have been enlarged into two images.

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!

 

Map 2

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!

The Heart of the 1947 Central and South Florida Project, the SFWMD

Everglades National Park, JTL

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.

The country as a whole was empowered with its post World War II success and prosperity, and with that same determination, the U.S. Congress came to Florida’s rescue…

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 including environmental 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)

Documenting the Discharges, 12-4-17, SLR/IRL

12-4-17, ca. 2:45 pm, photos: Ed Lippisch & Jacqui Thurlow-Lippisch

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!

Documenting the Discharges 11-19-17, SLR/IRL

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…”

*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: 

Last Thursday Shall Be Proclaimed “Water Tower Day,” as Lake O discharges reached the top! SLR/IRL


If the discharge waters of Lake Okeechobee filled up the City of Stuart, Florida. Last Thursday, they would have reached the top of Stuart’s iconic water tower that stands at 134 feet.

 

Stuart, North of Monterey.

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!”

Stop the Discharges

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…

Documenting the Discharges, 10-29-17, SLR/IRL

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

Irma’s Waters Ravage the St Lucie River/Indian River Lagoon, SLR/IRL

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…

Florida’s Flood System Built on 1947 Hurricane Season, Now Irma, SLR/IRL

Florida hurricane of 1947 https://www.youtube.com/watch?v=PgAHv_Z5wqE

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.”

Cover of the “Weeping Cow” book. (South Florida Water Management District)

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.

Map showing the Jacksonville District’s initial comprehensive proposal, 1947. (Claude Pepper Collection, Claude Pepper Library, Florida State University, Tallahassee, Florida)

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…

FPL revoir, Google Earth

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?

Water Quality Assessment of the St. Lucie River Watershed – Water Year 2017 – DRAFT- Gary Goforth, P.E., PhD. SLR/IRL

Dr. Gary Goforth ready to tour the SLR & Lake O.

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!

Reflections in the St Lucie River, JTL

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?)

Key Findings:
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[1] (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[2], exhibited a slight improvement in nutrient levels compared to their base periods, however, collectively these WY2017 loads did not achieve the alternative BMAP Phase 1 load target (Figures ES-1 and ES-2). The C-23 and Tidal Basins met the alternative BMAP Phase 1 target for TP, while the C-23, C-24 and Tidal Basins met the alternative BMAP Phase 1 target for TN. The predominantly agricultural C-44 Canal Basin exhibited poor nutrient conditions, and in fact, continued a trend of deteriorating nutrient conditions compared to its 1996-2005 base period. As a whole, the water quality entering the SLRE remains poor, although a slight improvement over the 1996-2005 period was observed.

The Line Between Past and Present: Corbett Wildlife Area, SLR/IRL

Ed looks outside the plane: a  “line” divides agricultural fields and the wetlands of J.W. Corbett Wildlife Area. 7-8-17.

An overview…
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!”

Pond apple blossom. Photo by Lisa Jefferson. There was a 32,000 acre pond apple forest on the Southern rim of Lake O prior to development.
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.

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…
Early rendition of the Everglades area including the rivers of the SLR/IRL. (Thurlow Collection.)
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…

“Algae Hunters” Track Significant Bloom Living in the Middle of Lake Okeechobee, SLR/IRL

My husband and I have decided we are algae hunters…

Hello Readers. Hope you are having a good summer!

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.

PRESS RELEASE:

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.

Goforth Graph Showing C-44 Basin Runoff into Lake Okeechobee, 2017, SLR/IRL

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.”

SLR basins. C-44 and surrounding man-made basin is in pink. This is the area that is being back pumped into Lake O as the lake has been low due to drought. But area rains in southern Water Conservation Areas are so full water “cannot be sent south…” South Florida Conundrum…SFMWD, 2017.
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:

This satellite photo shows water on lands in 2005. One can see the lands in the EAA are devoid of water. This water has been pumped off the lands into the Water Conservation Areas, sometimes back pumped into the lake, and also stored in other canals. *This slide is similar to what is going on today in June of 2017. Wildlife is drowning in the Water Conservation Areas (south of EAA) while the Everglades Agricultural Area is pumped dry to protect agriculture. (just south Lake O) Crazy. (Captiva Conservation 2005.)
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.”

Deadlines for EAA Reservoir and SB10, SLR/IRL

Aerials of A-1/A-2 region of the EAA, JTL/EL 2017

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.

WPTV’s “Changing Seas” Features St Lucie River’s Toxic Algae Saga, SLR/IRL

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.

CHANGING SEAS
Toxic Algae: Complex Sources and Solutions:

http://video.wpbt2.org/video/3002101897/

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.

Aerials of Our Rain Stained Lagoon, SLR/IRL

Recently, it seems to rain almost every day!

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.

Why are C-44 and S-2 flowing backwards into Lake Okeechobee? 

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

Jacqui,

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…

“Tainted Waters, Threats to Public Health, and the People’s Right to Know,” SLR/IRL

Cover to ACLU report, “Tainted Waters,” by John Lantigua, released  6-7-17.

Civil Lib·er·ty/(definition)
noun
“the state of being subject only to laws established for the good of the community, especially with regard to freedom of action and speech.
individual rights protected by law from unjust governmental or other interference.”

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.

Hurricanes, Discharges, and Monitoring Seagrass Loss in the Indian River Lagoon, SLR/IRL

IRL in Jensen, ca. 1948 Seymour Gideon property, courtesy Sandra Henderson Thurlow Archives. (Note clear water and abundant seagrasses.)

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.

Lake Okeechobee Blue-Green Bacterial Blooms in Florida: Lessons From Lake Erie, Prof. Geoff Norris, SLR/IRL

 

Blue-green algae bloom St Lucie River, 2016, JTL

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 rosalex@interlog.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

By Geoff Norris, PhD

University of Toronto: http://www.es.utoronto.ca/people/faculty/norris-geof/

rosalex@interlog.com

May 2017

 

Preamble

 

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.

 

 

Steel Town

 

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.

 

The Fix

 

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:

 

https://www.nwf.org/~/media/PDFs/Regional/Great-Lakes/GreatLakes-Feast-and-Famine-Nutrient-Report.ashx

 

The Monster Returns

 

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 hole
