They have only been found in a few places around the world, including Australia, Madagascar, New Zealand, Oregon, and South Walton County, Florida, with the largest of the lakes–Lake Powell–also stretching into Florida’s Bay County.

Believed to be as much as 10,000 years old, South Waltonâs dune lakes were originally formed by wind and waves and are constantly changing. The lakesâ water levels sometimes rise due to rainfall and inflow from streams, causing them to overflow, breach sand dunes, and send fresh water into the Gulf. Depending on the tides and other conditions such as shifting sands, water from the Gulf also flows into the lakes, carrying saltwater plants, fish, and other marine life along with it.

Habitats for Diverse Fish, Wildlife & Plants

Because theyâre made up of both salt and fresh water, coastal dune lakes are hosts to a diverse fish and animal populations, with species ranging from largemouth bass, bream, and catfish to flounder, shark, and speckled trout. They also provide homes for American alligators, eastern mud turtles, North American river otters, and more. And The lakes offer a habitat suitable for both fresh and saltwater plants.
