Disclosures Required in South Walton County

Coastal Dune Lakes are extremely rare ecosystems, which exist in just a few places around the world. They are primarily freshwater systems that sit along the coastline, but in South Walton County, the lakes periodically break through the beach and connect to the Gulf of Mexico. A saltwater exchange occurs, which supports an incredible biological community.

4.       Why are these lakes important? These coastal features are recognized by the Florida Natural Areas Inventory as globally rare and critically imperiled throughout the state of Florida. The changing condition of water chemistry in the coastal dune lakes makes them dynamic, biologically diverse ecosystems, Temporary estuaries and nursery grounds are formed when the fresh and saltwater mix, providing important breeding areas for birds and mammals. Beach dunes around the lakes provide habitat for the endangered Choctawhatchee beach mouse and threatened piper plover.

5.      What can you do to help preserve these unique natural treasures? Stay on the marked trails and boardwalks and avoid walking across dunes and trampling vegetation. Be respectful of the lakes and their natural process, do not dig in or around the lake outfalls. See 4.02.06(B)9 of the Land Development Code. It states that a 50 foot vegetated buffer will be left undisturbed along either side of the natural outlet from the lake.
