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

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.”

This applies to the Floridan Aquifer proper and the other aquifers above it, all below the Suwannee, Alapaha, and Withlacoochee Rivers, the Okefenokee Swamp, and their tributaries.

Waterkeeper Alliance advocates EPA and USACE restore longstanding protections for the nation’s waters 2025-04-23

Suwannee Riverkeeper, among 64 U.S. Waterkeepers, joined Waterkeeper Alliance and Environmental Integrity Project in asking the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers to maintain and restore longstanding protections for the nation’s waters.

Most of this long comment letter is applicable to the Suwannee River Basin. For example, related to the ongoing Georgia attempts to define which rivers and creeks are navigable: “lUnder the agencies’ Pre-2015 Regulatory Definition, all tributaries to traditionally navigable waters, interstate waters, impoundments, and ‘other waters’ are categorically defined as ‘waters of the United States.’” For example, see Valdosta sewage into Sugar Creek and Quitman sewage and cattle manure into Okapilco Creek, both into the Withlacoochee River in Georgia, upstream from Florida and the Suwannee River.

The comment doesn’t mention the Floridan Aquifer, but there are mentions of “Large numbers of rivers and streams… that briefly flow subsurface and then reemerge as surface waters.” and river-connected “subsurface flows and springs” elsewhere. Subsurface flows are important in the Suwannee River Basin and the Floridan Aquifer.

The Florida Basin Managment Action Plans (BMAPs) supposedly intend to reduce by 85-95% the leaching of fertilizer nitrates through the soil and subsurface limestone into springs and rivers, causing algae blooms and crowding out native vegetation, to the detriment of manatees and other wildlife.

Dock work at Gibson Park Ramp 2023-05-25

Gibson Park Ramp will not be closed for upcoming work, except possibly briefly.

Inquiring minds wanted to know, so I called Chuck Burnett, Director, Hamilton County Parks & Recreation.

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]
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.

The report is available Continue reading

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:

We last did a WWALS hike to the Dead River Sink on October 2, 2022, after paddling down the Alapaha River in the Alapaha River Water Trail (ARWT).

Not many miles, but packed with sinks, a beach, two rivers, and the big one: the Dead River Sink, on October 2, 2022. Thanks, Dennis Price, for leading us, and for chainsawing our way in.

Thanks to Phil Royce for helping haul a couple of boats up the Jennings Bluff stairs.

Sunday: Paddle Sasser Landing to Jennings Bluff, Hike to Dead River Sink, Alapaha River, 2022-10-02

Update 2022-10-02: Directions: Sasser Landing and Jennings Bluff, Alapaha River 2022-10-02.

Rescheduled a day later, to Sunday, October 2, 2022. Yes, probably the fastest reschedule ever. Turns out that Saturday is the Hahira Honeybee Parade, and we don’t want to disappoint 25,000 of our closest friends. So Sunday, October 2nd it is for the Alapaha River paddle and Dead River Sink hike.

A two-hour paddle down the Alapaha River, and a two-hour hike roundtrip up the Dead River to the Dead River Sink and back, with Practicing Geologist Dennis Price. If the Alapaha is low enough, we will also see two sinks in that river just before the Dead River Confluence.

There is nothing else quite like this in Florida (or Georgia). Dennis Price for years has been recommending a state park here, at these jewels of the Alapaha River Water Trail. Hamilton County is making a county park nearby on land it owns.

The Dead River itself is a distributary: the Alapaha River runs into it, down into the Dead River Sink, and does not come back up for twenty miles and three days until the Alapaha River Rise on the Suwannee River.
