Killing the Heart of Barley Barber Swamp

Every time I post, I learn something.  After reading “The Once Great Forests of Indiantown,” Stuart’s multi-generational resident, and dear friend of my mother, wrote:

“Jacqui, about 1968-9 my 4 hunting buddies and I went hunting in Indiantown in the Barley Swamp, there were huge cypress trees laying over?? Also walking through woods we came up on a mountain,”large Indian mound.” I have never found anyone who knew about the mound. Mid 70s I built a house that all the interior was don w/cypress from Barley Swamp, a sawmill north of Okeechobee cut it. Years later I was talking to a man I built for and he said his brother worked for FPL digging the dike, when digging, he found a carved stone face about 3x2x10 that “I thought looked like images found in Mexico and south,” I guess FPL might have dug up that mound…”

I’d like to thank Boo for his comment questioning why there were gigantic felled cypress trees in Barley Barber Swamp as late as 1968/69.  I had written in my blog that according to a 1930 Stuart News article, most of the cypress and pine trees five miles NW of Indiantown were timbered from 1920 through the later years of the 1930s.

Well, my brother Todd and I went back and tried to deduce a theory. The theory is that the timber companies, as reported in the July, 19, 1930 Stuart News article, had cut most of the trees “five miles west of Indiantown,” but no matter how they tried, their trams and tracks and axes and saws could not reach the deep interior of the swamp. Its heart! So some of the largest trees, as Boo, notes, were felled later, leading up to Florida Power and Lights digging, construction and diking of its Indiantown cooling reservoir.

For perspective, Todd shades below the visible dark river shape of Barley Barber Swamp over a 1940s Department of Agriculture aerial. The shaded area is 3078 acres or 4.81 square miles.

Below, in these Florida Department of Transportation aerials from 1971, at a lower altitude, we can clearly see the Barley Barber Swamp and encroaching agricultural lands that have already been cleared and de-stumped.

The remaining and distinctive thimble shape of Barley Barber Swamp remains today as seen in the 1971/Google Earth 2023 comparison. This would have been just two or three years after Boo Lowrey and his hunting buddy visited the area in 1968/69 and witnessed the giant cypress trees lying on their sides.

Todd also created a remarkable slider for comparison.  

By 1974, the remaining cypress forest of the once great Barley Barber Swamp was being burned, smoke rising to Heaven, to make way for the reservoir as can be viewed and compared in the slides below.

Heartbreaking. But as I am often told such is “progress.” I disagree.

And the Indian Mound? Of course it was right were the FPL reservoir was today. Boo saw it before most of it was drowned. It is no reach to make this deduction as  Big Mound City is known worldwide as “the largest prehistoric Native American earthwork in southeastern Florida.” It was huge and lies a few miles south from Indiantown, not far from the lake, in J.W. Corbett Wildlife Area. These were ancient “cities” along Lake Okeechobee. In fact, when Indiantown was named “Annie” in 1915, long after the native people were gone, the year the St. Lucie Canal was started, there was actually an Everglades Drainage District survey documenting the road from Annie to Big Mound City. Indiantown to Big Mound City? Not far at all.

I hope this sheds light on the history of the heart of the “once great forests of Indiantown,” and unfortunately, how they were killed.

From FPL’s website. I came across this after I wrote my blog post and  felt I should share.

Also a great image showing how the swamp lay right in the middle today’s FPL cooling pond-from Wikipedia’s article on Barley Barber Swamp.

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?
