Sneads Smokehouse Lake: Dried-Down Headwater of the Aucilla River

1.3K

A few weeks ago, I began to visit sinkhole lakes that have dried down during this “exceptional drought” we’ve been experiencing. Last year, I started a different mission, to trace the headwaters of the Aucilla River. Today, these two storylines converge at Sneads Smokehouse Lake.

Our first stop on the Aucilla mission was Lost Creek Forest, north of Thomasville, Georgia. Here, hillside seeps turn to marshy creeks, joining together to form an Aucilla Creek that flows into Florida. As you can see in the map below, it’s hard to make out a channel as it flows into the water body we see north of Asheville Highway, in north Jefferson County. South of the bridge, we can see where the Aucilla flows into Sneads Smokehouse Lake. The round section off to the left is the lake’s main sinkhole.

This is the area we’re exploring today.

It’s April of 2026, and the map I’m embedding shows water that is not present today. If it stays dry for long enough, the imagery will update to show that. Today, we’ll be walking on dried out lake and river beds.

Freeing the Sinkholes in Sinkhole Lakes

This drought is harsh, and it could have lasting ecological and economic repercussions. And yet, now is a time to witness a landscape normally hidden from us. The bathtub is empty, and we can walk lake and river bottoms. Today, I’m joined by someone who may well have walked more of these drained bathtubs than anyone.

We’ve explored numerous sinkhole lakes with Michael Hill over the years. Before he retired from FWC twelve years ago, he worked on restoring lakes whose sinkholes had been dammed or otherwise altered. The story here is similar to Lake Miccosukee or Lake Lafayette. When a lake dries down, people see water flowing into a sinkhole, and they see fish flopping around on exposed lake bed. They worry about the health of this ecosystem. So, decades ago, people isolated sinkholes from several local lakes.

As Michael told us when Lake Jackson dried down in 2021, by the time water starts to empty into the sinkhole, the lake has already lost a lot of its water by other means. It evaporates, and is consumed by plants that transpire it into the atmosphere. It sublimes through the sandy bottom into the underlying limestone.

Michael points out that these lakes have done this for many thousands of years. The plants and animals here have evolved with these wet and dry cycles. Altering these cycles alters the character of the water bodies.

Here at Sneads Smokehouse, the additional concern for some people was that, when this lake dries down, it affects the flow of the Aucilla River. Over a decade ago, though, Michael removed its dam and let this part of the river go dry from time to time. It seems unusual to see a dry riverbed in north Florida. But then, the Aucilla is an unusual river.

Aucilla, the Quintessential Sinkhole River

If Lake Jackson is the quintessential sinkhole lake, the Aucilla might be the quintessential sinkhole river.

I learned this while producing Finding the First Floridians, an archeology documentary that spends a lot of time on the Aucilla. This river is a hotbed for old archeological sites as well as ancient animal fossils. During filming, I found myself in a fossil warehouse at the Florida Museum of Natural History, in front of long shelves of Aucilla and Wacissa River sloths, mastodons, bison, and other ice age residents of the area.

Dr. Richard Hulbert, the retired Director of Vertebrate Paleontology at the Museum, explained that sinkholes are extremely effective at preserving fossils and artifacts. As he describes it, the river is full of them. “The modern Aucilla River is essentially a fairly shallow, small flowing body that’s sort of connecting a series of sinkholes.”

When humans first arrived in this area at least 14,700 years ago, the water table was lower, and the river did not flow regularly. These sinkholes were gathering places for animals and humans alike. Some of their encounters are recorded in sediments within the sinks.

There were likely less trees then, but the First Floridians would have seen the river as we’re seeing it today. I do want to make clear that seeing the river dry near its headwaters doesn’t mean that it’s dry all the way down. As Michael points out, many other sources feed the river as it flows into the Gulf (after making a few subterranean detours into the aquifer).

Let’s follow the Aucilla to the sinkhole in Sneads Smokehouse Lake

In the riverbed leading into the lake, there are puddles of various sizes, and several wood storks take turns foraging in mucky spots. As we learned on Lake Jackson a couple of years ago, a moving shoreline creates new feeding habitats for birds. Storks find food in shallow, muddy water.

We can see a lot of dead vegetation lying in mats. We can also see that grasses and living vegetation have greened the empty river bed outside of a small channel. This area has been dried-down for a while.

Now, closer to the lake:

From the spot above, we can head east and see this:

“When you see the organic material that starts cracking like this, it’s a good time to really scrape it out,” Michael says. “When there’s too much muck, then it interferes with the successful reproduction of all the sunfish, and even our largemouth bass is in the sunfish family. It’s called a bass, but it’s a really a sunfish.”

When a sinkhole lake dries down, this organic matter dries up and breaks down. When it doesn’t, it will form floating islands of vegetation called tussocks. Plants as large as trees will grow on these islands, and what had once been an open and grassy lake can become a forested wetland. If you recently read our Upper Lake Lafayette sinkhole story, this may be repetitive. Lower Lake Lafayette is what happens when a lake is cut off from its sinkhole.

And now, we approach the sinkholes

In the image above, at the top of the water body, we can see where a stream bed leads into the sinkhole basin from the rest of the lake. We see this kind of stream leading to all of our dried down sinkholes. This one has run dry. The small trench at the lower right is a connection to an adjacent sinkhole.

A moment before we stepped down to the lake, I heard something like a fireworks display, if all the explosions were splashes. These were the alligators we had just photographed from across the sinkhole. I think I spooked them.

WFSU News Director Regan McCarthy is tagging along today, and she took the time to count the alligators before they all jumped in. Her tally was 41, but those are just the ones she could see at the surface.

Once the gators are all in the water, an osprey flies in over the sink and pauses as if to dive. We all watch expectantly, but it must see what we see and thinks better than to try its luck here.

This had once been a much larger water body. Alligators, and the fish they eat, have concentrated into this submerged sinkhole basin. When animals fill a small water body and eat, pee, and poop in it, it can affect that water body in a highly visual way.

Algae Bloom in Sneads Smokehouse Lake

The northern end of the sink basin is tinted bright green. Michael says this is cyanobacteria, also known as blue-green algae. The wind has pushed it to one side of the water body.

This is a small water body with a lot of wildlife. Nutrients are concentrating in it, and the weather is getting warmer. Michael says that cyanobacteria blooms aren’t always toxic, and there are plenty of living animals here. But it is a concern, as is the lake’s oxygen level.

“There’s quite a bit of organic material there,” Michael says. “And as it’s decomposing, the bacteria uses up oxygen… the fish that are in there are using the oxygen. And, if it’s real still and really hot, the water can’t hold as much oxygen. So it compounds in there.”

If the oxygen level gets too low, it could spur a fish kill. He says the alligators would likely eat them until they started to rot. Then, they would have to move on.

A river shaped by sinkholes

Here’s another fun thing Michael pointed out. In the map above (embedded April 2026), we can see the river heading south and east into the lake. But we can also see the ghost of a bygone Aucilla channel to the west. Michael says that when the sinkhole first formed, it started taking in water and slowly pulled the river to it over geologic time.

The river flows for over thirty miles before another sinkhole swallows it up. The Aucilla River paddling guide only recommends kayaking or canoeing 15 of the river’s total 75 miles, adding ten for expert paddlers who don’t mind a lot of portaging. We kayaked part of this upper stretch of the trail with Doug Alderson a few years back, and we did spend a lot of time hopping over fallen trees or lugging canoes and kayaks around them.

Even this longer version of the paddling trail starts several miles downstream of Sneads Smokehouse Lake. The stretch between is not navigable.

To recap for those who didn’t read our first headwaters story: Where the paddling trail ends, the river enters the aquifer. It next appears in a series of karst windows known as the Aucilla River Sinks. After that, it rises and falls for a couple of short stretches. In one of those, known as Half-Mile Rise, contains our area’s oldest confirmed archeological site: Page-Ladson. The Aucilla River finally re-emerges for good at Nutall Rise, flowing into the Gulf.

The spring-fed Wacissa River joins with the Aucilla at Half-Mile Rise, and also at Nutall Rise. This watershed is a masterclass in north Florida karst features.
