Dune lakes are found in very few places in the world.
These are lakes that create an opening to the Gulf of Mexico in times of high water levels which causes the fresh and salt water to mix and create some of the most distinct ecosystems in the world, harboring many different marine species. The Beaches of South Walton are home to 15 of the most unique and rare coastal dune lakes.
These rare dune lake systems can only be found along the coasts of New Zealand, Australia, Madagascar and in the United States they are found along the Oregon, South Carolina and Northwest Florida coast lines. Because the ecosystems are so rare and they provide such a unique habitat for different plants and animals they are considered wetlands and are therefore protected by the state.
What makes these lakes so unique is called the outfall. Depending on the tide this is where a channel forms between the lake and the Gulf. Salt water can flow from the Gulf into the fresh water of the lake or from the lake to the Gulf.
The water in the lakes is dark brown or tea-colored with natural tannins from leaves falling into the lake, and is not harmful. These outfalls and lakes are favorite recreation areas for visitors and residents. These lakes provide an excellent scenic escape for kayaking, canoeing, and fishing.
