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

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:

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

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.

Videos: Geography of Opportunity, by Vickie Everitte, a WWALS Webinar, 2025-12-11

History Instructor Vickie Everitte conducted a historical exploration of Georgia’s Wiregrass Region and the complex stories of survival, resistance, and adaptation that unfolded there after the 1814 Treaty of Fort Jackson.

WWALS Board Member Janet Martin gave a brief introduction to this WWALS Webinar. Questions and answers were at the end, including a distinguished guest.

Native American and Passageways to Freedom within the Wiregrass Region1

As settlers moved south of the Oconee River, drawn by the land’s economic promise, waves of migration and militia efforts reshaped the landscape—and the lives of the Native American families who called it home. Through rivers, streams, and the vast Okefenokee Swamp, Indigenous people found ways not only to endure but to carve out paths of freedom and self-determination amid the U.S. Indian Removal Policy of the 1830s.

Drawing from original correspondence between settlers, militia, and Georgia’s governors in Milledgeville, this presentation reveals how waterways became corridors of escape and survival. As Everitte reminds us, “Swamps are places on the margins — as much, they are places of transition, opportunity, and challenge.”2

Video: How Humans Affect the Aquifer, a WWALS Webinar by Dennis Price, 2025-06-19

Update 2025-07-25: SRWMD & SJRWMD aquifer recharge project update @ SRWMD 2025-07-08.

Dennis Price, P.G., of Hamilton County, Florida, asked, “Are we just a water tower for Jacksonville?”

He showed us “the history of surface and ground water in the flatwoods in south Georgia and north Florida in the Suwannee River Basin. Historic water levels and how we have changed these levels. Changes beginning with forestry then farming, and population growth. Ideas for correcting the problems.”
