bout the St. Marys River

About the St. Marys River

The St. Marys River is a remote blackwater stream, located in southeastern Georgia and northeastern Florida, forming the easternmost border between the two states.

While visiting the river, you may see many native plant species, including bald cypress, longleaf pine, black gum, southern magnolia, red maple, American holly, poplar, black willow, river birch and a variety of oaks.

The St. Marys serves as critical habitat for numerous rare, threatened or endangered species, including 23 kinds of plants and 54 kinds of animals. Wildlife in this area include porpoise, manatee, osprey, bald eagle, white-tailed deer, black bear, bobcat, raccoon, otter, beaver, gopher tortoise, alligator and indigo snake.

Canoeing, boating, fishing, camping and water-skiing can be enjoyed on the river.

Shorelines are fragile and susceptible to erosion. The following guidelines will help to minimize erosion and maximize river aesthetics:

  • Maximize and/or retain native shoreline vegetation.
  • Maintain a vegetative buffer between the river and structures.
  • Construct access walkways and smaller docks.

More than 65 species of fish have been identified in the St. Marys River. At the river’s mouth, the estuarine system provides fishing enthusiasts with an abundance of redfish, spotted sea trout and flounder. Largemouth bass, panfish and catfish inhabit much of the middle and upper portions of the St. Marys.

Anglers may fish either side of the river and need a valid Florida or Georgia fishing license.

Launching Watercraft

The channel of the St. Marys River is tidally influenced for 50 miles upriver with an average depth of 20‒30 feet. Visitors should check weather conditions and tides before launching.

  • Along the upper river, there are many “S” turns and oxbows, with numerous white sandbars.
  • The upper stretches are unsuitable for powered craft.
  • Heavy rainfall or dry conditions can affect sections of the river, such as from the headwaters in Moniac, Ga., to the State Road 121 bridge just north of Macclenny, Fla.
  • Reliable paddling depth starts at the State Road 121 bridge north of Macclenny.
  • Conditions favorable for water-skiing are found from Camp Pickney eastward. The sport is not allowed from the railroad trestle westward and is limited between the trestle and Camp Pickney.
  • Boaters should be aware of sandbars, shoals, blind curves, and floating and underwater logs and take appropriate safety measures when encountering these hazards. High water conditions can also present dangers.

Various camping sites exist along the St. Marys River.

Much of the land bordering the river is privately owned; therefore, permission should be obtained from the landowner to camp.

When camping, please respect the environment and remember to do the following:

  • Take out what you bring in.
  • Use only down and dead vegetation for fires.
  • Extinguish all campfires.
