- Coastal Plain: The Coastal Plain is the region of Georgia that lies between the Atlantic Ocean and the Piedmont Plateau. It includes the Okefenokee Swamp and the Altamaha River basin, which are important habitats for Georgia river otters.
- Piedmont Plateau: The Piedmont Plateau is the region of Georgia that lies between the Coastal Plain and the Appalachian Mountains. It includes the Chattahoochee River basin and the Flint River basin, which are also important habitats for Georgia river otters.
- Ridge and Valley: The Ridge and Valley is the region of Georgia that lies between the Piedmont Plateau and the Appalachian Mountains. It includes the Coosawattee River basin and the Conasauga River basin, which are less common habitats for Georgia river otters.
Georgia river otters are found in all 159 counties of the state, but they are most common in the coastal plain and the piedmont plateau regions.
