Video: Okefenokee Swamp leaks into the Floridan Aquifer peer-reviewed evidence, WWALS Webinar, 2026-01-15

2 Replies

Thanks to UGA Professors Jaivime Evaristo (isotope data) and Todd Rasmussen (water levels) for reviewing their two lines of evidence that the Okefenokee Swamp leaks through the underlying limestone into the Upper Floridan Aquifer.

This webinar explains their recent scientific paper on this subject.

Note that this means that nearby water withdrawals draw more water down from the Swamp into the Aquifer.

This paper is more incentive to pass Georgia House Bill 561 to protect the Okefenokee Swamp from mining, at least on its east side. Georgians, please ask your statehouse delegation to pass HB 561. Floridians, please ask your Georgia friends and relatives to do the same. Here’s how to contact Georgia Statehouse members:

Update 2025-01-17: Video.

Hahira, Georgia, January 12, 2026 — For thirty years it was suspected that the Okefenokee Swamp leaks water into the groundwater from which we all drink. Now we have much stronger evidence, that the Swamp leaks not a little but a lot of water into the Floridan Aquifer.

At noon by zoom this Thursday, you can watch the UGA professors who published it explain that evidence.

They will also mention some consequences, such as nearby water withdrawals pull more water from the Swamp into the Aquifer.

Lead author Prof. Jaivime Evaristo will explain the isotope evidence. Prof. Todd Rasmussen will explain the water level evidence.

Prof. Evaristo and Rasmussen will speak for about 45 minutes.

Questions and answers will be at the end.

Filthy Hightower Creek 2026-01-08 but clean upstream ILM Pond 2026-01-09

1 Reply

Update 2026-01-16: Clean Ichetucknee, Santa Fe, Withlacoochee Rivers 2026-01-14.

Thanks to the landowners, on Friday John S. Quarterman tested ILM Pond at the top of Hightower Creek, west of I-75, and found its level well below its outflow pipes. Also, it tested pretty clean, despite the geese that land there. So that can’t be the source of contamination into Hightower Creek.

On Thursday, Suzy Hall tested Hightower Creek at St. Augustine Road and found it still dirty. Downstream, she also tested Sugar Creek at the WaterGoat and found it OK, not far upstream from the Withlacoochee River.

There’s no water in Hightower Creek all the way from ILM Pond under I-75. Until just below the Sam’s Club detention pond. So that seems like a good place to test next.

This image is an overview. Scroll down for the details.

This is an update to the WWALS Friday Weekly Water Quality Report in which we found the Withlacoochee River clean, and the Santa Fe River.

The inch of rain Saturday last week had little effect, and the drizzle this Saturday probably even less.

No new sewage spills have been reported since then in Georgia or Florida.

The weather is supposed to be fine but cold today, so if you can find a river with enough water, and happy paddling, motoring, swimming, and fishing.

Clean Withlacoochee River downstream 2025-11-22

Update 2025-11-28: Clean Withlacoochee River, Mostly Clean Sugar Creek 2025-11-26.

Better news from two recent Withlacoochee River water quality samples.

Apparently the effects of the small Valdosta sewage spill into Sugar Creek Wednesday have washed out of the Withlacoochee River downstream, at least where we tested.

Suzy Hall got zero (0) E. coli for Friday at State Line Boat Ramp, aka Mozell Spells.

John S. Quarterman got 100 cfu/100 mL for Saturday nine miles upstream at Clyattville-Nankin Boat Ramp.

Those are both less than the 126 cfu/100 mL three-test average limit, so quite clean.

This image is an overview. Scroll down for the details.

Clean downstream Withlacoochee River, State Line 2025-11-21, Nankin Boat Ramp 2025-11-22

Nankin Boat Ramp is also 15 river miles downstream from US 84 and 27 miles downstream from GA 133 where Valdosta Utilities got way-too-high E. coli for Thursday. And about 30 miles downstream from Sugar Creek, where WWALS tester Suzy Hall got even worse Too Numerous to Count (TNTC) for Wednesday.

These new WWALS results match the zero (0) that WWALS tester Russ Tatum got for Wednesday at Holly Point, on the Withlacoochee River in Florida a few miles upstream from the Suwannee River.

So if you can find enough water, happy paddling, motoring, swimming, and fishing, at least downstream on the Withlacoochee River.

Videos: Bradford Road Denied @ Berrien County Commission 2025-11-04

The Berrien County Commission denied the subdividing issue before them: the six lots on Bradford Road, at their November 4, 2025, regular meeting.

However, many irregularities were raised.

[Bradford Road Denied @ Berrien County Commission. Many irregularities raised, 2025-11-04]
Bradford Road Denied @ Berrien County Commission. Many irregularities raised, 2025-11-04

The other lots on Old Valdosta Highway were already decided by the same Commission in 2024, and the minutes for that meeting say at the request of John and Tonia Beville.

At this meeting, John Beville said he and she had not requested that, and never saw any Public Hearing signs posted, even though they lived there at the time. When questioned by the Commission, Zoning Coordinator Teresa Willis said it was done for South Auction, and “Russ” brought the plat to her. She did not say who Russ was.

Della Gladieux pointed out that the three Planning Commission Public Hearings this year all had both plats advertised, for the lots on Old Valdosta Highway, and for the other lots on Bradford Road. She also pointed out other issues in the document she handed the Commissioners: Formal Complaint and Demand for Investigation Re Bradford Road –Della Gladieux 2025-11-04.

Lisa Sumner also spelled out numerous issues.

Below you can see the entire Berrien County Commission meeting of November 4, 2025 in the WWALS videos of each agenda item and speaker, plus a few still pictures, followed by a WWALS video playlist.

Valdosta sewage spill into Sugar Creek –WCTV 2025-11-20

Update 2025-11-25: Clean Withlacoochee River downstream 2025-11-22.

The WCTV report includes:

Earlier this year, the North Florida Rivers Task Force met with Valdosta leaders about several spills along the same water way.

One riverkeeper said he wants to see more improvements.

[Valdosta sewage spill into Sugar Creek, Suwannee Riverkeeper --WCTV 2025-11-20]
Valdosta sewage spill into Sugar Creek, Suwannee Riverkeeper –WCTV 2025-11-20

“The positive side is they seem to be getting smaller, so that is good,” executive director of [WWALS Watershed Coalition] John Quarterman said. “Valdosta utilities fixed it pretty quick and they put out a press release as well, in less than 24 hours, so that is good. Of course, nobody is going to be happy until there are no more sewage spills.”

See Mishalynn Brown, WCTV, Nov. 20, 2025, Sewage spill reported in Sugar Creek, Valdosta utilities says: The utilities department advised that residents avoid the area.

Thanks to WCTV producer Michael Clark for interviewing me via zoom. I must work on my halo.

The WCTV report starts by reviewing the Valdosta press release, which Continue reading →

Filthy Sugar Creek and Withlacoochee River upstream; downstream and Alapaha River OK 2025-11-20

Update 2025-11-25: Clean Withlacoochee River downstream 2025-11-22.

Update 2025-11-23: Valdosta sewage spill into Sugar Creek –WCTV 2025-11-20.

Apparently the small Valdosta sewage spill into Sugar Creek Wednesday affected that creek and the Withlacoochee River more than expected.

WWALS tester Suzy Hall for Wednesday got TNTC (Too Numerous to Count) at the WaterGoat, just before the river. Downstream on the river, Valdosta Utilities for Thursday got 2,670 at GA 133 and 1,035 at US 84, both higher than the 1,000 alert limit for E. coli.

Yet WWALS tester Russ Tatum got zero (0) for Wednesday at Holly Point, on the Withlacoochee River in Florida a few miles upstream from the Suwannee River.

Also for Wednesday, WWALS tester Heather Brasell got OK results for the Alapaha River at Sheboggy Boat Ramp at US 82. WWALS testers Bob Mills and Kurt Hurzeler got good tentative results at their Santa Fe River site upstream from Poe Springs.

Of course, the high results could be due to the so far unknown source upstream of St. Augustine Road on Hightower Creek.

No other sewage spills have been reported in the Suwannee River Basin in the past week in Georgia or Florida, so far as we can tell, although FDEP’s Pollution Reports web page and map are both not working corectly. At least we didn’t get any emailed reports for Florida this week.

No rain is expected for the next ten days.

So I’d avoid Sugar Creek and the Withlacoochee River near it. Other than that, happy paddling, swimming, fishing, and boating this weekend. If you can find enough water to do those things. Maybe far downstream on the Withlacoochee or Suwannee Rivers.

Or join us tomorrow for Knights Ferry to Nankin Clean Up, Withlacoochee River 2025-11-22.

Clean Santa Fe River and Withlacoochee downstream; Dirty Hightower and Sugar Creek 2025-11-12

The Santa Fe River and the Withlacoochee River downstream tested clean for Wednesday.

But WWALS got too-high results at the WaterGoat on Sugar Creek for Monday, and both WWALS and Valdosta Utilities got too-high results upstream on Hightower Creek at St. Augustine Road. In addition, Valdosta Utilities got too high at GA 133 on the Withlacoochee River downstream from Sugar Creek.

These continuing high Sugar Creek results are still mysterious, especially given no rain to wash residue downstream.

No sewage spills have been reported in the Suwannee River Basin in the past week in Georgia or Florida, except a small spill from a force main break Monday in downtown Chiefland, Levy County, Florida.

No rain is expected for the next week.

So I’d avoid Sugar Creek and the Withlacoochee River near it. Other than that, happy paddling, swimming, fishing, and boating this weekend. If you can find enough water to do those things. Maybe far downstream on the Withlacoochee or Suwannee Rivers.

Or join us next Saturday, November 22, for Knights Ferry to Nankin Clean Up, Withlacoochee River 2025-11-22.
