Located in Central South Carolina, Lexington is the largest town and county seat in Lexington County. Lexington is seated between the North Fork Edisto River to the southwest and the city of Columbia and the Congaree River to the east. The county is drained by the Saluda River, which is impounded by the Saluda Dam to form Lake Murray. Lexington county’s southernmost portion lies in gently rolling Coastal Plain terrain, the central portions lie in Fall Line hills, and the northern sections, with pine and hardwood forests, fall in the Piedmont.
