Guntersville Lake (generally referred to locally as Lake Guntersville) is located in north Alabama between Bridgeport and Guntersville. Created by Guntersville Dam along the Tennessee River, it stretches 75 miles (121 km) from Guntersville Dam to Nickajack Dam. It is Alabama's largest lake at 69,000 acres (280 km²).
The lake and dam received its name from the town of Guntersville, which received its name from an early settler of the area, John Gunter.
