Alapaha Swallets Dye Trace Project 2016-10-01

Down at the designation of the new Jennings Bluff State Geological Site with Dead River Sink 2023-03-17 the Florida Geological Survey (FGS) was giving out links to a report on the Alapaha Swallets Dye Trace Project.

That’s where FGS, FDEP, and SRWMD put fluorescent green dye in the Dead River Sink, back on June 22, 2016, and watched for it to come back up.

Before and After

As you can see by the graph, the dye came back up four days later in the ALapaha River Rise, and eight days later in Holton Creek Rise.

Withlacoochee Springs and Slough, Sullivan Launch 2023-07-15

Join us for a leisurely paddle by second magnitude Hardee Spring and other springs, as well as Fennels Funnel, a sinkhole leading to the extensive M2 Blue cave system, and Chitty Bend East Distributary, where some of the Withlacoochee River runs into the woods into some swallets.

When: Gather 9 AM, launch 9:30 AM, end 2:30 PM, Saturday, July 15, 2023

Put In: Sullivan Launch, The first public access point in Florida to the blackwater Withlacoochee River, Sullivan launch is a narrow concrete launch with free parking and a picnic area, but no picnic tables. It is in the Sullivan Tract of Twin Rivers State Park. From Pinetta, Madison County, FL, travel east on CR 150; turn right at the bridge and follow road to the launch south of the river bridge. Downstream it’s 8.8 miles or about 4.4 miles to paddle to Florida Campsites Ramp. First thing you’ll see is the twisted remains of the old Bellville Bridge, and on the right bank the Pinetta gauge.

Pictures: Jennings Bluff Florida State Geological Site with Dead River Sink 2023-03-17

Update 2023-05-01: Alapaha Swallets Dye Trace Project 2016-10-01.

A congenial time was had by all on a balmy north Florida day at the Dead River Sink (or swallet) as the Florida Geological Survey incorporated it into the new Jennings Bluff Tract State Geological Site.

The Dead River Sink in the Suwannee River Water Management District (SRWMD) Jennings Bluff Tract is one of the most popular spots for WWALS outings on the Alapaha River Water Trail.

Here is a WWALS video playlist by Gretchen Quarterman, who also took the still pictures except where otherwise indicated:

KUR: M2 Blue cave system, Madison County, Florida

Update 2022-01-10: Chitty Bend East Distributary, Withlacoochee River –Shirley Kokidko 2022-01-07.

What’s underneath the Mystery: Withlacoochee River Distributary 2021-01-01? The M2 Blue cave system in Madison and Hamilton Counties, explored by Karst Underwater Research (KUR).

There’s a “Gully / Swallet” marked on this KUR map of the M2 caves, very close to where the sinkhole at the end of the distributary. Both maps in this post are credited to KUR. Please follow the links for the rest of KUR’s descriptions, pictures, and videos. Continue reading

Sulak’s Defeat at Jennings Defeat 2020-08-26

Explorer Dr. Ken Sulak has solved an Alapaha River rapids naming mystery. He recounts:


So in 1797, Samuel Taylor Coleridge wrote a poem inspired by a dream.

Where Alph, the sacred river, ran
Through caverns measureless to man
   Down to a sunless sea.

So twice five miles of fertile ground
With walls and towers were girdled round:
And there were gardens bright with sinuous rills,
Where blossomed many an incense-bearing tree;
And here were forests ancient as the hills,
Enfolding sunny spots of greenery.

Insert three ‘A” and the dreamscape river becomes the Alapaha, and appropriately so. Yesterday, I embarked on the foolish idea of a solo kayak journey up 3 miles of the Alapaha from Sasser Landing (just below the confluence of the Alapaha and the Alapahoochee rivers) to the site of the 1800s Roebucks Ferry and later Roebucks Bridge.

That crossing brought settlers and other travelers from Jacksonville and Fernandina along the GA/FL border across the Alapaha to Miccotown, the old Seminole Indian town in the triangle of land protected by the two flanking rivers. The road/trail (gone now on both sides) continued west across the Alapahoochee at the site of the early 1900s Beatty Bridge (undoubtedly preceded in the mid-1800s by an undocumented ferry), and on to Hickstown in Madison County and westward. Miccotown became the first county seat of Hamilton County as the settlers suppressed the Seminoles and the old Indian town faded into obscurity in 1839. Continue reading

Delineation of Spring Protection Areas

These figures tell the story of springsheds in a coastal lowland karst plain such as much of the Suwannee River Basin. Maybe you already know all this, but if you don’t, these pictures may help make sense of Springsheds and Water Withdrawal Permits in the Suwannee River Basin.

Where to look for dye from Alapaha Dye test

Update 2023-05-01: Alapaha Swallets Dye Trace Project 2016-10-01.

Tom Greenhalgh dying the Dead River, Harley Means, and a drone Tom Greenhalgh started putting the dye in the Dead River Swallet about 11:06 this morning, with Harley Means observing in this picture, plus a drone also taking pictures. See below for where to look for the dye coming back up in the next few days. If you see it, please take a water sample for SRWMD. Continue reading

Get Sabal Trail out of vulnerable karst –EPA to FERC

Avoid the whole most vulnerable area of the Floridan Aquifer, you risk drinking water wells and environmental justice communities, you didn’t even identify Clean Water Act mitigations, neglect isn’t mitigation, and stop just tweaking Sabal Trail’s preferred route even if Sabal Trail is at risk by its contract: your process is broken, FERC! Furthermore, all agencies means you, too, FERC, about the December 2014 Revised Draft Guidance for Greenhouse Gas Emissions and Climate Change Impacts. This project is so bad EPA is setting aside its stance that natural gas is cleaner and demanding a full life cycle analysis of the Transco – Sabal Trail – FSC project.

Above I paraphrase, but I do not exaggerate the severity and extent of EPA’s criticisms of FERC’s DEIS for the proposed Sabal Trail pipeline. Read it for yourself below.

EPA specifically criticizes the proposed HDD drilling under the Withlacoochee River slightly upstream from Blue (Wade) Spring, and going anywhere through the eroded karst sinkhole-prone terrain of southern Brooks and Lowndes Counties, Georgia, as well as in Florida through the Cody Scarp with its springs, swallets, siphons, and merging sinkholes, under the Suwannee River, over Falmouth Cave, and under the Santa Fe River.

Florida Sierra Club did this: Continue reading
