Pictures: Alapaha River Rise Hike 2025-11-01

Thanks to landowner Byron Herder for inviting us to go see the Alapaha River Rise from his surrounding property after we hiked from the Dead River Sink to the Dry Alapaha River. About half a dozen of us took him up on that, include WWALS Board member Bret Wagenhorst.

The Rise is just upstream of the CR 249 or CR 751 Bridge, aka Nobles Ferry Bridge, which is just upstream of Gibson County Park and the Alapaha River Confluence with the Suwannee River. That’s about eighteen river miles downstream from the Dead River.

As Byron pointed out, the Alapaha River Rise is not just a first magnitude spring, at a daily flow of 383.9 million gallons per day (mgd), it dwarfs all the others in the Suwannee River Basin. (There are five with more flow, on Crystal River and Rainbow River.)

Second most flow in the Suwannee River Basin is Holton Creek Rise at 157 mgd, a bit upstream on the Suwannee River. That’s also the other place dye came back up from the Dead River Sink in the 2016 Alapaha Swallets Dye Trace Project.

Both Rises have more flow than can be accounted for by the Dead River Sink alone, even adding in the other sinks in the Alapaha River slightly upstream of the Dead River. Continue reading

We climbed over, under, and around much Hurricane Helene deadfall on what Dottie Price called a “Class 5 Meander” from the Dead River Sink to the Dry Alapaha River.

Thanks to 30 people who came, to Practicing Geologist Dennis J. Price for leading this expedition, and to Dottie Price for the additional pictures. See also the facebook video by Christiaan Ard.

There was a false start at Jennings Bluff Cemetery, where Dennis told the lemmings to go back up the bluff, because of too much deadfall. Continue reading

Hike with a Geologist to a Spring, the Dead River Sink, and the Dry Alapaha River

Hahira, Georgia, October 30, 2025 — Join us this Saturday, November 1, 2025, on an approximately 3 mile or 4 hour hike on the Dead River and the dry Alapaha River bed, led by Practicing Geologist Dennis James Price of Hamilton County, Florida.

Hahira, Georgia, October 30, 2025 — Join us this Saturday, November 1, 2025, on an approximately 3 mile or 4 hour hike on the Dead River and the dry Alapaha River bed, led by Practicing Geologist Dennis James Price of Hamilton County, Florida.

[Hike to Dead River Sink, Alapaha River, Jennings Bluff, with Practicing Geologist Dennis Price 2025-11-01]

We will meet at 9:30 AM at Jennings Bluff Cemetery. On a short stop there, we will climb down a steep bank to explore a spring. Then we will drive into public lands to the Dead River Sink where we will hike out to the Alapaha River and hike the river bed.

From Jennings, Florida, go south on US 41 approximately 2.25 miles and turn left onto NW 25th Lane, which dead ends at the Jennings Bluff Cemetery on the Alapaha River. GPS: 30.56693, -83.035297

This area has recently been designated a State of Florida Geological Site.

Much of the year, the Alapaha River is dry for the last eighteen miles from Jennings Bluff to the Suwannee River, because its water flows into the Dead River and down into the Dead River Sink. On June 22, 2016, several Florida agencies put fluorescent green dye into the Dead River Sink. The dye came back up four days later in the Alapaha River Rise, and eight days later in Holton Creek Rise, both off of the Suwannee River.

Bring sturdy boots or shoes, clothes for woods with stickers, water, and snacks.

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.”

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
