The Dramatic Shifting Sands of Ft Lauderdale, SLR/IRL

Comparison of 1883 historic map and Google Earth image 2017, Ft Lauderdale’s New River Inlet

Today I am sharing two creations of my brother, Todd Thurlow. Entitled “Ft Lauderdale House of Refuge/Life Saving Station,” and “Short Version,”they were originally for my mother, Sandra Henderson Thurlow and Timothy Dring’s “Image of America, U.S. Life Savings Service” book presentation at the Elliott Museum.

For me, Todd’s videos are mind-boggling as they bear witness to how much and how fast we humans can change the  environment. Like an army of ants, we organize; we build; we destroy; we create…

By comparing and contrasting Google Earth maps of today with historic maps from 1883, 1887, and 1935, Todd’s “time capsule flight,” takes us through time and space to see the shifting sands of the multiple New River Inlets; Lake Mabel that morphed into Port Everglades; remnants of the forgotten Middle River that spread and contracted into new canals and developments; and of course, for mom, House of Refuge #4, that once rested north of a New River Inlet that today we can see is completely filled in, while beach-goers relax in reclining chairs like nothing ever happened!

Maybe one day we humans can use all this energy and ability to really fix our waters that have been destroyed during all this construction? Wouldn’t that be a dramatic video?

In closing, in the early 1900s, the New River… that was believed by the Seminoles to once be an underground river that collapsed and the Great Spirit revealed during an earthquake… was selected by modern-day humans as the “natural channel” to connect two of the largest drainage canals from Lake Okeechobee to the Atlantic Coast, the North New River/South New River, and the Miami.

Please watch and enjoy Todd’s videos below!

How to Alleviate the Lake O Destruction to the St Lucie River/Indian River Lagoon, SLR/IRL

The chart below provides a good visual of 2016 Lake O releases though the C-44 Canal from S-80 comparing 2016, 2013, and 2015. S-80 discharges include the surrounding man-made basin as well as releases from Lake Okeechobee. This info has been compiled by my brother, Todd Thurlow, http://www.thurlowpa.com/LakeOLiveData/ via SFWMD. (Automatic updates every 7 days.)

In order to fix a problem, you have to know what the problem is…..yesterday’s visual makes clear to all the problem. Don’t be mistaken, this problem although overwhelming, can be greatly alleviated –“fixed.”

In March of 2015, the University of Florida published: OPTIONS TO REDUCE HIGH VOLUME FRESHWATER FLOWS TO THE ST LUCIE AND CALOOSAHATCHEE ESTUARIES AND MOVE MORE WATER FROM LAKE OKEECHOBEE TO THE SOUTHERN EVERGLADES. This was an independent technical review by the University of Florida Water Institute.

(http://waterinstitute.ufl.edu/research/downloads/contract95139/UF%20Water%20Institute%20Final%20Report%20March%202015.pdf)

The 134 document summarizes three things necessary to give relief to the estuaries:

  1. 200,000 acre-feet of water storage within the St Lucie River watershed. (*For C-23, C-24, C-25 and C-44 canal alone—not including releases from Lake Okeechobee through C-44 JTL)
  2. 400,000 acre-feet of water storage within the Caloosahatchee watershed.
  3. approximately 1,000,000 acres of water storage distributed north and south of Lake Okeechobee.

Senate President Elect Joe Negron’s plan for land purchase in the EAA fulfills part of #3. This reservoir would be “dynamic,” meaning that in simple terms it would hold, clean, and move water south to the Everglades. In other words, it would move multiple acre feet over time.

Our St Lucie River is degrading in ways that may not be reversible. We must work for land purchase south of Lake Okeechobee to begin to alleviate the destruction. —We must not just support, but also help Joe Negron. Get ready for Florida’s legislative session 2017.file-page1

Dodging the Bullet, St Lucie River Shot In The Chest, SLR/IRL

Martin County was fortunate to “dodge the bullet” of category 4 Hurricane Matthew, but as long as the St Lucie Indian/River Lagoon is attached to Lake Okeechobee via the C-44 canal, the river cannot. She is shot in the chest each time.

These photos taken yesterday morning by my husband, Ed, show the discharges, like blood, gushing out of the St Lucie Inlet. Melodramatic personification? Perhaps, but true.

A press release by the Army Corp of Engineers on October 7th stated:

“Lake Okeechobee continues to rise; today’s stage is 15.93 feet… 

The Corps has resumed discharges from Lake Okeechobee after suspending them during the storm. Water managers have removed target flows and will release as much water as practical through Moore Haven Lock (S-77) located on the west side of the lake, and the Port Mayaca Lock (S-308) located on the east side of the lake…

‘We anticipate inflows to the lake will increase as a result of Hurricane Matthew,’ said Col. Kirk. ‘Therefore, we must maximize outflows in order to slow the rise in the lake and be as prepared as possible for additional hurricane season uncertainty…”

“Additional uncertainty?” Not for the river.

As the Corp has been discharging from the lake since January 29th, 2016 and now the gates are wide open to save life and property south of the lake, the St Lucie did not really dodge a bullet at all. She is hemorrhaging once again.

Until Lake Okeechobee is redirected south as God designed, “dodging a bullet” in Martin County remains an illusion.

I am lucky to know a lot of people who are smarter than me. And one of them is my brother. Ever since we were kids Todd read meteorological books or the Guinness Book of World Records. He likes data.  Today, over forty years later, he is helping me apply his knowledge of data to the St Luce River/Indian River Lagoon.

If you are a regular blog reader, you know that this past summer Todd helped publicly identify what became a 240 square mile algae bloom in Lake Okeechobee that was being released into the C-44 causing our river to become toxic. Today, I will share his ideas on avoiding the perfect toxic algae storm.

Here is a photo of Todd and I when we were young in the 70s, when the river was in better shape and we were having fun fishing on Ronnie Nelson’s dock on Hutchinson Island.001 (485).jpg

Here is a photo of Todd and me today. As you can see we have changed a lot and the river has changed too…

IMG_3163 - Version 2.JPG

So recently, this Friday when the Army Corp increased releases to the St Lucie Estuary I wrote Todd. (Press release: http://www.saj.usace.army.mil/Media/News-Releases/Article/952594/lake-okeechobee-flows-to-increase/)
I think the exchange is insightful so I am going to share:

Jacqui: “Todd, how does the lake look? ”

Todd: “Clear. I have been posting every 8 days.

After studying these satellite aerials for a while, I can tell that the blooms are definitely related to sunlight and wind..Our scientists friends would sarcastically say, “no kidding?!”

High pressure system -> a lot of sunlight + no wind = bloom. Clouds + wind = less algae.

The fresh water, phosphorus and nitrogen are always in the lake, but not necessarily the river. Luckily, cloudless days are also the perfect time to spot the algae by satellite.

Maybe the ACOE  should add to their discharge schedule that they will hold back the releases when it is forecast to be calm and sunny for several days to prevent the risk of and bloom in the estuaries? Then they can pulse the releases again when the clouds and wind pick up and the algae blows away in the lake – kind of like mother nature.

Jacqui: “Always better if we go with Mother Nature so we don’t end up with such ecological disasters…”
Todd: ” I think Gary Goforth, Mark Perry and others would tell us that the disaster timeline sets up like this:

– A low pressure weather system moves into Florida and dumps a bunch of rain, local runoff begins and the lake starts to rise
– They keep S-308 at Mayaca an other lakeside gates closed and open S-80 because the priority is always to transport the “local” runnoff first and not add to flooding problems by sending lake water through the coastal canals
– The local basins start to drain out and a high pressure weather system moves in. It gets sunny, hot, and the wind dies down to zero.
– With a lot of sun and no wind, the lake starts to bloom. With local runoff subsiding, the tides help flush all to local runoff out to sea but not completely.
– Just when conditions in the lake are “the perfect storm”, the estuaries would otherwise be recovering from the local runoff, the lake is in full bloom and rising, S-308 is now opened to drop the lake at the worst time. All the algae that just exploded in the lake is transported down C-44 through S-80 and into to estuaries. Salinity in the estuaries stays low instead of naturally recovering. With the sunny conditions and unnatural discharges, the estuaries explode with algae blooms.

If they would just delay opening S-308 for just a few days, maybe a week, allowing clouds and wind to return, could the perfect storm be avoided?”

Thank you Todd! Hope the ACOE thinks on this. We don’t want to get in the Guinness Book of World Records 2016 for the estuary with the most toxic algae blooms!

Do Lake Okeechobee’s Algae Blooms Grow on “Rocky Reef” Above Clewiston?

(Movie showing a close-up of the Rocky Reef overlaid with today’s image and a NOAA Chart-By Todd Thurlow)

 

As we know, my brother Todd has been keeping his eye on the Landsat satellite images as they provide tremendous insight into the condition of Lake Okeechobee and potential algae blooms that affect the health, safely and welfare of those living around the St Lucie River/Indian River Lagoon. Todd notes that in studying the Landsat images: “Perhaps the algae grows on Rocky Reef? The area just north of this location is were some of the earlier blooms originated.”

Hmmm? Could the Rocky Reef be an area where the water cannot flow in the lake as easily due to its nature? Could it be possible that nutrient rich back pumped waters from the sugar fields fester in this area feeding a lake wide bloom? Worth a thought as we try to fix our problems…

The toxic algae blooms –people are still talking about them….

You may have noticed recently in various publications and “Letters to the Editor” across the state that some are calmly claiming that “algae blooms have been occurring in Florida since the beginning of time…” This may be true, however, this summer’s 240 square mile algae bloom in Lake Okeechobee that led to the outbreak in the St Lucie River was unprecedented. Comparing the situation to prior algae bloom outbreaks of 2013, 2014, or any other is like comparing a dog to a wolf. The same but very different.

Another interesting thing Todd stumbled upon while researching the “Rocky Reef” located basically above Clewiston was a 1977 joint NASA/SFWMD report on, of all things, using Landsat radiance data to study the turbidity and chlorophyll concentrations in Lake Okeechobee.

The report is entitled: LANDSAT INVESTIGATION OF WATER QUALITY IN LAKE OKEECHOBEE, PRESENTED AT THE 1977 ASP-ACSM CONVENTION IN WASHINGTON DC FEB 27-March 5, 1977. (http://www.sfwmd.gov/portal/page/portal/pg_grp_tech_pubs/portlet_tech_pubs/dre-71.pdf)

Since obviously the South Florida Water Management District has been using the Landsat information since 1977, and Martin County has been paying taxes to the District since around the same time, I think it would have been polite if the District had let us know when Lake Okeechobee’s then poisonous waters were overflowing with algae and headed this way. Don’t you as well?

You can learn about Todd’s discoveries about the Rocky Reef below.

That 16.8 square mile area in the southwest looks like algae but part of it is apparently the “Rock Reef”.

Satellite Images Reveal Another Significant Algae Bloom in Lake O, SLR/IRL

Because the Army Corp of Engineers has been discharging into the St Lucie River for the past months and the nightmare of June’s algae situation, my brother has been monitoring satellite images of Lake Okeechobee. Unfortunately, another large bloom has been documented. For awhile the large bloom that reached a size of over 200 square miles seemed to subside and was not not very visible via satellite …

Since August 19th, 2016 a visible bloom is back.

Considering what happened in June and July of this year, we as a community should be prepared for another possible river algae outbreak if this bloom significantly grows or other conditions are right–presently, Todd measured the bloom at just over 40 square miles. (See below)

Many reports and Facebook posts have already surfaced about algae blooms building up again in marinas and along shorelines. Hopefully if there is an outbreak, it won’t be as extreme as earlier this year when the Governor declared a state of emergency.

Thank you Todd for the information and the images.

We will keep reporting.
