Coastal Dune Lakes: Rare, Beautiful, and Right In Our Backyard!

Beautiful view of a coastal lake. We have vacation rentals nearby.

If you’ve been to South Walton, Florida you know what a magical place it is. The crisp, white sand beaches and clear, turquoise water are exactly what you think of when you imagine the perfect beach.

But has your vision of the perfect beach ever included a lake— hidden behind the dunes?

Probably not.

Did you know that South Walton is home to this extremely rare natural phenomenon? And not just one. There are fifteen coastal dune lakes here!

Coastal dune lakes are bodies of water formed on the coastline by high winds. Over time, the winds moved the sand to form shallow basins near the shore. These lakes only exist in a few areas of the world— Madagascar, New Zealand, Australia, Oregon— and right here in South Walton, Florida.

How cool is that?

South Walton’s dune lakes are said to have formed over 10,000 years ago by wind patterns coming in off the Gulf of Mexico. They are fed by a combination of rain, streams, and groundwater. Most of the lakes are about five feet deep.

What makes them so special is that their mainly freshwater contents are a few feet from the salty Gulf of Mexico. During periods of high tides or excessive rains, the lakes will breach the sand berm and empty into the Gulf.

This process is called “outfall.”

During that time, the salty water from the sea also enters the dune lake. This creates a rare brackish water environment that is home to both fresh and saltwater species of plants and animals.

Thankfully, Walton County and organizations like the Choctawatchee Basin Alliance protect these fragile lakes. They track the water quality and don’t allow anything invasive to upset the delicate natural balance.

During your stay on our coast, take advantage of these rare and precious wonders by renting a kayak or a stand-up paddleboard to go exploring. Topsail Hill park also offers guided tours through Campbell Lake with a park ranger.

Fishing in the lakes is allowed and is generally freshwater. But some saltwater species are caught here, too. Panfish, flounder, catfish, and redfish are most common.

Plants and animals that are native to the area help to maintain the lakes’ rare ecosystems. Wetland plants like sawgrass, saltbush, sand cordgrass, and duck potato perform essential water filtration functions. They also are a food source and habitat for wildlife.

Each lake’s water quality is different depending on the season, amount of rainfall, and its rhythm of outfall. Some lakes can be completely fresh, while others can be significantly salty.

When visiting the lakes, stay on marked trails and boardwalks and avoid walking across dunes or seagrass.

While all the dune lakes are beautiful, some lakes are easier to access than others and offer more activities for exploring. Be sure to check them out during your stay.
