Campbell Lake is a freshwater body located in Walton County, Florida, nestled within the beautiful coastal dune lake system that runs along the area's beaches. This lake, found within Topsail Hill Preserve State Park, is part of a rare geological feature that only occurs in the Florida Panhandle, Madagascar, Australia, New Zealand, and the northern Pacific coast of the United States. As one of Florida's coastal dune lakes, Campbell Lake offers a unique fishing environment where anglers can target various freshwater and occasional saltwater species. The lake is fed by streams, groundwater seepage, and rain, with periodic connections to the Gulf of Mexico through outfalls, creating a distinctive ecosystem for fishing.
