This email came in via my brother Todd this morning, amazing how similar the paths of the two hurricanes are. I thought I’d share. In any case, to all “be safe.” Jacqui

I continue to take great pleasure in featuring the “time-capsule flight” historic map and Google Earth work of my brother, Todd Thurlow.(http://thurlowpa.com)
Today’s short video focuses on our beloved South Fork area of the St Lucie River. This video visually juxtaposes 1940s U.S. Government maps to Google Earth images of today. The video begins over an undeveloped Horseshoe Point, Sewall’s Point, and St Lucie River proper and then travels in a southern direction to the wide fork of the St Lucie River and deep along its wild, winding, and African-looking curves. One sees the old Palm City and new Veteran’s Memorial bridges come and go, and notices the build up over time of sand in the fork (maybe some from dredging and some from sediment build-up from Lake Okeechobee releases.) This serpentine and beautiful section of the South Fork is southerly of Highway 76 that runs out to Lake Okeechobee alone the C-44 canal. Today’s I-95 exchange is also visible.

And the little ponds! My favorite! Just everywhere!This is most incredible to me as today they are “gone.” These hundreds, if not thousands of little ponds, once slowly increased and decreased in depth and size based on rainfall, overflowing at times, into the winding South Fork. One can still see the lush vegetation surrounding some of these areas. Can you imaging the wildlife that used to be in our area? I so would have loved to have seen it but this trip is better than nothing!
As the flight continues, “today’s” development is neatly stacked right up to the winding edge of the fork on the south side in particular…makes me think of septic tanks???
I have to say it nice that there is some land around the areas of the fork and I am sure local environmentalist have fought to keep this over the years. Nonetheless, if we had it to do over again, I think we would decide to leave a much wider birth around these important watersheds.
In the final minutes of the video we travel over the dreaded C-44 canal built in the 1920s, known in its early years as the “St Lucie Canal.” This canal of course, connects Lake Okeechobee to a section of a second prong (fork) in the winding South Fork. The canal itself is wider and apparently the “connection is just “above” today’s Four Rivers which lies beyond the I-95 bridge and exchange and All American Marina.
Zooming in and out in time and place, one can see the cleared lands around St Lucie Locks and Dam and white sand piled high from dredging on the north side of the canal….The picture fades in and out as we view the old locks structure compared to its “new and improved” version today….
I just love this stuff. It makes it all so easy to “see.”
The environmental destruction that is…I guess for others it is the sight of money and making a swamp “useful.” How ever you view it, the journey is an education.
Thank you to Todd for opening my eyes and for allowing me to travel in time and “place.”

It is an amazing thing to fly through time and space, and this is exactly what I did yesterday with my brother, Todd. He took me on a “flight” over a 1958/Today St Lucie River, North Fork, and Ten Mile Creek. All the while, the images flashing in and out of past and present….Please watch this short video yourself by clicking the link or image above.
At one point along our armchair journey, I said to myself, “Wow, I don’t feel so great,” –just like sometimes when I am with Ed, my husband, in the airplane. I actually got motion sickness having plastered my face right up to the screen to see every moving detail!
A few deep breathing exercises put the feeling off, but next time I’ll take my Dramamine!
Google Earth image at the northern reaches of what was Ten Mile Creek in St Lucie County. Algae in agriculture canals is very visible.
This flight, as the others you may have experienced on my blog with Todd, is amazing. It allows one to really see what the lands were originally like and how they have been developed as residential homes and endless agriculture fields.
Towards the end of the video, you can even see algae growing in the agriculture canals, off of Ten Mile Creek, St Lucie County–“bright green,” for all to see on Google Earth. I have witnessed these green canals too from an airplane.
Due to drainage canals— leading to drainage canals—leading to drainage canals, this water from the ag fields, and from all of our yards, ends up in the now sickly St Lucie River. This problem is exacerbated by ACOE/SFWMD releases from Lake Okeechobee and the basin area of C-44 in Southern Martin County. These canals and the expanded engineered runoff from the lands is what is killing our river.
It is my hope that with visuals like the video above, future generations will find a way, and want to be a part of a new water and land management generation “seeing” how to improve St Lucie River/Indian River Lagoon. Our generation seems stuck in a quagmire….
Like they say: “seeing is believing,” and seeing provides insight for change.

Northern reaches of the North Fork of St Lucie River, Ten Mile Creek in St Lucie County, 1958. Wetlands showing multiple small ponds are visible. These lands were drained in the 1950s by canals C-24, and further south C-23 and further north by C-25. These canals were part of the USACOE and SFWMD’s effort for more flood control and to expand agriculture and development: These canals are part of the Central and South Florida Flood Control Project of the 1950s which allowed more non flooding development and agriculture, but also destroyed our valuable south Florida waterways.

Link to short video journey showing the former swamp “Alpatiokee” juxtaposed to today’s agriculture and development– Post St Lucie and western Martin County,
The first map in the video is a 1823 U.S. Army Map showing “Al-pa-ti-o-kee Swamp,” as it was known. The second is a 1846 map by Bruff. We then fly in to view Green Ridge, and the ridge just east of Indiantown. Next, we then overlay the 1983 Topo maps to view Green Ridge again, fly up, and around, Ten-mile Creek, and then back down the North Fork of the St. Lucie River. —-Todd Thurlow
Not only was the city of Port St Lucie a swamp, but western Martin County was too. Please view the above video and “see” for yourself! It must have been a fabulous place, now long gone, know as “Alpatiokee,” or “Halpatiokee Swamp.”
Meaning “alligator waters” by the Seminoles, these lands/waterways were traversed for centuries in hand-made canoes. The native people and the Seminoles traveled many miles through the St Lucie River/Indian River Lagoon, and during rainy season they could travel all the way up into the St Johns River. How? Because these lands, when flooded, were “connected.” Now they are not only no longer connected but water that flowed north into the St John’s flows south into the St Lucie River….
Back to Port St Lucie…..
Recently, I kept noticing that the 1856 “Everglades” Military Map I like so much showed an expansive swamp close to where Port St Lucie and western Martin County are located today.
“This is weird,” I thought. “What happened to the old swamp?”
So, I contacted my brother, Todd, who loves maps and can combine them together with technology. (See link/video above.)
Below you’ll find an edited version of Todd’s notes to me.
I find all of this absolutely fascinating, and sometimes a bit unsettling….The natural ridges in the land we seem to ignore; how we blew canals through them; how the water USED to flow; how humans have developed and built agricultural empires, and changed everything….Maybe one day with visual tools like these, future land planners, and water district employees can change back some of our landscape to it’s former glory, and maybe even return a few gators to the landscape, since it’s named after them.
That would be nice, something more to look at while driving the Turnpike than “concrete.” 🙂
Halpatiokee or Alpatiokee translates as “alligator water” in the Seminole language. (Public photo.)

TODD’S NOTES REGARDING VIDEO:
THE OLD MAPS: The old maps are not necessarily accurate, but they give an idea… They show basically what was known as the “Hal-pa-ti-o-kee Swamp.” On some other maps it is labeled the “Al-pa-ti-o-kee Swamp.” On almost all old maps, it would cover the area that is labeled Allapattah Flats on the modern topographical maps — but Hal-pa-ti-o-kee was probably more to the east.
———————-
Google Earth image 2015, Todd Thurlow.
TOPOGRAPHY AND RIDGES: There are two distinct ridges in western Martin County. Green Ridge is about 4.6 miles west of the turnpike, (12.5 miles west of the ocean), and can be seen on aerials. The western edge of Allapattah flats is a ridge where the elevation goes quickly from about 30 fee to 40 feet. This ridge (an obvious ancient ocean shoreline) can be seen running all the way to Cape Canaveral parallel to the coast. This ridge is about 12.5 miles west of the turnpike (20 miles from the ocean). Indiantown sits on the high side of the ridge. This Hal-pa-ti-o-kee Swamp on those old maps would be the we area east of the Indiantown ridge – so it is basically all of western Martin and St. Lucie County.
FORMER WATER FLOW: Probably everything east of the Green Ridge flowed east into the St. Lucie. Everything between the two ridges flowed north to the St. Johns watershed and everything West of the Indiantown ridge (not much) flowed west into Lake Okeechobee via the little creeks on the east bank of the
….Somewhere between the St. Johns and the St. Lucie so everything between the two ridges, but north of that point, went north to the St. Johns River. Everything south would have gotten picked up by Ten-mile creek in the extreme North Fork of the St. Lucie River, which actually flowed north-east before turning back south to the St. Lucie.
CONCLUSION: There are academics that would know this stuff for sure and all the proper names. These ridges are like little continental divides, separating water flows into separate directions like the Rocky Mountains. When they busted all these canals through the ridges they changed the direction of all the water flows from mostly north/south to east/west. But that was the goal — get it to sea level as quickly as possible and drain the swamps…

From the time I was a baby until growing up, I remember lots of ponds here in the region of the St Lucie River/Indian River Lagoon. Hundreds of ponds intertwined with scrub lands…
Some of these boggy ponds were right outside my neighborhood in St Lucie Estates, just off of East Ocean Boulevard. It was the 1960s and 70s. Over time, especially in the 80s and 90s, when I had grown up and was off to University of Florida and beyond, these ponds simply dried up and “disappeared.” These lands became shopping centers, an expanded Witham Field, gas stations, schools, golf courses, and more neighborhoods. The same thing happened to the lands out west of town, but they became expanded agricultural lands. At a kid, I didn’t think too much about it. Today it blows my mind.
The aerial at the top of this blog post is from 1940. I was born in 1964. The small dark areas are ponds. When I asked my brother Todd, who is very knowledgeable on these old photos and land use, where all the ponds went, he noted that when our area canals were constructed by the water districts and Army Corp of Engineers, from about 1920 to the 1960s, the canals not only drained the lands, but over time, the water table dropped, (the water below the surface of the soil that you don’t see) drying out the many of little ponds, so that these lands could be developed.
Canals in Martin and St Lucie counties, C-23, C-24, C-25 were constructed in the 50s and 60s. C-44 is connected to Lake Okeechobee but also drains the agricultural lands around it. It was constructed in the 1920s.
So most of the 1940 wetlands you see in the aerials throughout this blog are now gone, and “we are here.” This happened all over Martin, St Lucie and almost all counties of south Florida. This on top of the shrinkage and drainage of giant Lake Okeechobee!
Yikes!
There is something is really odd about this. Millions of people living in former wetlands. Like sitting atop a dry sponge. No wonder all the wildlife is gone and the rivers are polluted. I’ve heard people talk about this change forever, and I have lived it myself, but seeing my brother’s video below, really bring the whole thing “home.” Watch and wonder where we should go from here…
Click here to see Martin County’s land use change over time, and watch the little ponds/wetlands “disappear. ” Time flight video by Todd Thurlow:
The flight starts in the area around Pratt & Whitney in northern Palm Beach County / southern Martin County where the land still looks like much of Martin County used to look. We then fly to the area around Bridge Road where the headwaters of the South Fork used to be nice and wet in the 1940s. Hundreds of interconnected ponds and bogs eventually coalesced into the tributaries of the South Fork. Today the ponds have been drained for farming and a few neighborhoods. The smallest tributaries are now drainage ditches. Next we fly over the area around the City of Stuart and Witham Field. You can see how the old ponds and bogs lined up between low ridges that run parallel to the ocean. Many of the bogs are now low-lying dry nature preserves in the neighborhoods and golf courses. –Todd Thurlow

“The only thing that is constant is change…” Heraclitus
In a world that is constantly in flux, it is natural to try to make things permanent. Nonetheless, this is to no avail. Nowhere is this as strikingly apparent as our barrier islands off the U.S. Atlantic coastline, right here at home, along our beautiful Indian River Lagoon.
As you know, over thousands of years, storms, winds and tides, along with other forces, have caused the openings of natural inlets along the Indian River Lagoon. Since the late 1800s, humankind, with the help of the Army Corp of Engineers, has “determined” where “permanent” inlets should be located, and filled in those otherwise forming…
My brother, Todd Thurlow, (http://thurlowpa.com) has finalized his Time Capsule Flight video of “The Inlets of Peck’s Lake and the Jupiter Narrows,” that I first shared with you in “trial version” last week. His result is even more remarkable.
Through the overlay of Google Earth, historic aerial photographs, NOAA, and USGS maps, his work provides a look back in history to see that our coastline south of today’s St Lucie Inlet has broken through at least four times to form four natural inlets since 1947.
They are: 1947 (1.1 mile south); 1952 (0.5 miles south); 1958 (1.1 south again or another in close proximity; and 1962 at Peck’s Lake during the famous Ash Wed storm.
At one point, I tried to pin Todd down about the number of barrier island breakthroughs. This was his reply:
“Jacqui – at least four breaks sounds right, but I am sure there have been an infinite number of breaks over the centuries – Joes point, Herman Bay, the Cove at IRP, Big and Little Mud creeks… “
I also tried to get an answer out of him that I have been wondering about for years: “How much shoreline along Jupiter Island near Peck’s Lake has “disappeared?” Todd was quick to say that it is “not that easy” and that this area has probably been coming and going for a long, long time…
Nonetheless, it is cool to think about. Here is his map. According to Todd, the red polygon in the attached image measures 445 Acres – approximately the amount of land that disappeared between Peck’s Lake and the Inlet since the 1887 NOAA chart. The yellow line measures 1770 feet – a third of a mile.
Yikes! 🙂

I am excited that Todd is sharing his “evolved” Thurlow map talents, and I am looking forward to a 2015 where he is a regular guest on my blog, taking us all to a high and fluid perspective where we can see change along the St Lucie River/Indian River Lagoon in a way never before.
Spoil island history, MC, FL (A time-capsule “flight” by Todd Thurlow.)
For today’s post, I am partnering up with my younger brother, attorney, Todd Thurlow. Todd, as all members of my family, is intrigued by history and maps. As he is a technology buff as well, he has learned to use Google Earth Pro (in this case a trial version) to superimpose old maps over today’s Google Earth aerials. The effect is amazing in that one can literally “see” the changes over time in land, shoreline, and in today’s case, IRL spoil islands. The islands that one sees in the IRL are not natural, they are dredge fill from the creation of a channel with its government beginnings in 1881. This includes some islands that are now exclusive neighborhoods, such as Island Edition and Archipelago, in Sewall’s Point. Fortunately, the birds got one too–“Bird Island” now a Critical Wildlife Area, (CWA) or MC2. MC2 is located just north, off the Archipelago.
Today our channels are managed by FIND, the Florida Inland Navigation District.
I will provide a summary TIME LINE of Todd’s notes below; nonetheless, be sure to watch the video in the link below, so you can “see!” It is amazing: you will feel like you are taking a time-capsule flight right over our beautiful and ever-changing Indian River Lagoon:
Question: “When Did Spoil Islands “appear” in the Martin County Area of the Indian River Lagoon?”
TIME LINE
1881: Florida Coastline Canal and Transportation Company was formed
1887: Aerial shows no spoil islands in IRL
1890: Dredging complete from Haulover Cut in Merritt Island to Jupiter
1892: Locals dig St Lucie Inlet by hand
1920: No spoil islands east of Sewall’s Point. US ACOE recommends dredging 8 feet deep and 75 foot wide from Jacksonville to Miami
1930: ACOE increases recommended width to 100 feet from 75
1935: Work complete-8 feet deep and 100 feet wide channel
1940: USDA map aerial shows spoil islands deposits on east side of Sewall’s Point (these became Island Edition and the Archipelago developments among other things…)
1945: Congress authorizes ACOE to dredge 12 foot deep 125 foot wide channel
1952: USDA map showing spoil islands DIRECTLY EAST of Sewall’s Point
1958: USDA aerial still shows no spoil islands on EAST SIDE of channel near Sewall’s Point (these are new islands, not the ones already deposited off of the near east side of SP)
1960: Due to ACOE determination, IRL portion between Ft Pierce to Miami is dredged to 10 feet rather than the 12 feet wanted in 1945
1963: NOAA chart shows new channel but no new islands still on the EAST SIDE of the channel off of Sewall’s Point
1965: ACOE work complete– based on 1945 and 1960 determinations
1970: Aerial finally does show spoil islands on EAST SIDE of channel off of Sewall’s Point from dredging/channel projects
1970: Aerial reveals, if one looks closely, that the smallest of the spoil islands to the EAST of the channel off of Sewall’s Point has since disappeared….
Todd Thurlow has given presentations at Stuart Heritage and Florida Oceanographic (http://thurlowpa.com) Call him if your club would like a presentation. Todd and I will be doing more work together in the future!
*I must also credit my dear river activist friend, Ezra Appel, who recently got me interested in spoil islands all over again. Ezra got involved two years ago with the Indian River Lagoon Aquatic Preserves (IRLAP), when his company adopted a spoil island in Vero Beach. Now he is involved with a newly formed group “Friends of the Spoil Islands, Inc, ” a 501 (c) non-profit, Community Service Organization working in partnership with the DEP and IRLAP. Ezra sits on the board as the Treasurer. They have a Facebook page: (https://www.facebook.com/spoilislands) Check it out! Ezra also shares with me aerial photos from INDIAN RIVER BY AIR; they have some great shots of the spoil islands in their neck of the woods: (http://www.indianriverbyair.com/tagged/spoil%20island)
