Florida Panhandle Region

The Northwest Florida Water Management District, the state agency charged with the water resources of the Florida panhandle, defines its region as 16 counties covering 11,305 square miles and about 1.5 million residents (NWFWMD).

Those counties are Bay, Calhoun, Escambia, Franklin, Gadsden, Gulf, Holmes, Jackson, Leon, Liberty, Okaloosa, Santa Rosa, Wakulla, Walton, Washington and the western part of Jefferson County (Northwest Florida Water Management District). The district is one of five created by the Water Resources Act of 1972, and it takes in only the western part of Jefferson County.

This guide uses the district's 16-county region as its working definition of the Panhandle. It runs from Escambia County, which FDEP calls the Panhandle's westernmost county, east to Leon, Wakulla and western Jefferson counties (FDEP Escambia County guide).

In the Panhandle the Eastern and Central time line follows the Apalachicola River south from Jim Woodruff Dam, then the Jackson River and the Intracoastal Waterway west to the west line of Gulf County, and that line south to the Gulf (49 CFR 71.5).

The federal rule that sets the line starts at the southwest corner of Georgia, runs to the midpoint of the Apalachicola River on the downstream side of Jim Woodruff Dam, and follows the middle of the river's main channel south to the Jackson River (eCFR). The same section places every municipality located on the boundary line in the central standard time zone.

The Citronelle Formation, a Pliocene deltaic deposit of poorly sorted sand with significant clay, silt and gravel, is mapped in 11 Panhandle counties, while the Ocala Limestone is at or near the surface in the Dougherty Plain District of the north-central Panhandle (USGS; USGS).

USGS describes the Citronelle Formation as gray to orange, often mottled sand that ranges from clean to clayey, with beds and lenses of gravel that change over short distances (USGS, Citronelle Formation). It is mapped in Bay, Calhoun, Escambia, Gadsden, Holmes, Jackson, Liberty, Okaloosa, Santa Rosa, Walton and Washington counties. Much of it is highly permeable, and it forms the Sand and Gravel Aquifer of the surficial aquifer system. Laterally it grades, through a broad facies transition, into the Miccosukee Formation of the eastern Panhandle.

The limestone country is different. Within the Dougherty Plain District of the north-central Panhandle the Ocala Limestone shows extensive karst, with relief of tens of feet and numerous disappearing streams and springs (USGS, Ocala Limestone). The same limestone is at or near the surface in the Ocala Karst District of the west-central to northwestern peninsula, and USGS calls it one of the most permeable rock units in the Floridan aquifer system.

Florida's highest point is in the northern end of Walton County in the Panhandle, at 345 feet, which FDEP notes is the lowest state high point in the country (FDEP Walton County guide).

FDEP places the high point at Lakewood Park, marked by a monument with nature trails around it (FDEP). FDEP describes the county as running from turquoise Gulf waters and white sand dunes in the south to that high point in the north.

The Panhandle coast includes Walton County's 15 coastal dune lakes, a type of lake FDEP says can be seen in only four other places in the world (FDEP).

FDEP names those four places as Australia, New Zealand, Madagascar and Oregon, and estimates the Walton County lakes formed between 2,000 and 10,000 years ago. Large sand dunes up to 30 feet tall separate the lakes from the Gulf, but they exchange water with it intermittently through an outlet, and Topsail Hill Preserve, Grayton Beach and Deer Lake state parks protect several of them (FDEP Walton County). Behind the beaches, Choctawhatchee Bay covers about 129 square miles in Okaloosa and Walton counties.

At the western end, Escambia is the Panhandle's westernmost county, and the Santa Rosa Island and Perdido Key barrier islands shelter its coastline, and FDEP lists 39 miles of sandy beaches in the county (FDEP Escambia County guide). FDEP notes that the same sheltered geography once made Pensacola sought after by Spain, France and Britain.

At the eastern end, Franklin County is known as the Forgotten Coast for its 53 miles of mainland coast, sheltered by the St. Vincent, Cape St. George, St. George and Dog Island barrier islands (FDEP Franklin County guide). St. George Island is a 22-mile island reached across a 4-mile bridge, FDEP's text says the Apalachicola National Estuarine Research Reserve conducts research and stewardship over 245,000 acres of the Apalachicola River and Bay system, while the same guide's at-a-glance table lists the reserve at 246,766 acres. FDEP describes the Apalachicola Bay Aquatic Preserve inside it, with seagrass beds, mollusk reef and salt marsh, as one of the most productive estuarine systems in the Northern Hemisphere, and the region's oysters have been sold locally since 1836 (FDEP).

Three state geological sites on the Florida Geological Survey list show Panhandle geology: Florida Caverns in Jackson County, Rock Bluff in Torreya State Park on the Apalachicola River and Wakulla Spring in Wakulla County (Florida Geological Survey).

Florida Caverns State Park, designated in 2000, sits along the Chipola River in Jackson County, where limestone more than 30 million years old is exposed, and FGS says it is the only Florida state park with guided tours through a large cave system (FGS). Its cave formations include stalactites, stalagmites, columns and flowstone.

Rock Bluff in Torreya State Park, designated in 2022, is a 100-foot outcrop at the eastern edge of the Apalachicola River floodplain and one of the tallest natural geologic exposures of rock and sediment in Florida (FGS state geological sites). Wakulla Spring, designated in 2018, lies in the Woodville Karst Plain of Wakulla County; its cave system extends more than 44 miles and feeds more than 250 million gallons of water a day to the spring.
