Located between the cities of Guntersville and Bridgeport, Guntersville Lake is the largest man-made lake in Alabama. At just over 69,000 surface acres, it also ranks as the largest lake in the state. This freshwater reservoir serves an important role in the state economy. In addition to generating power via the nearby Guntersville and Nickajack Dams, the reservoir also provides water for local agricultural production, controls flooding in the region, and offers recreational opportunities for residents and visitors.

Guntersville Lake was formed due to the construction of Guntersville Dam in 1939. The dam impounds the reservoir and feeds into nearby Wheeler Lake. Meanwhile, the Tennessee River feeds into the reservoir via the Nickajack Dam further upstream. When measured from Guntersville Dam to Nickajack Dam, the lake measures nearly 75 miles long.  Multiple other waterways flow into the reservoir, including Scarham Creek, Big Spring Creek, and Honeycomb Creek. The lake features numerous coves and inlets, as well as approximately 949 miles of shoreline. While the lake encompasses a large area, it doesn’t measure that deep. Although it has a maximum depth of 60 feet, most measure no more than 15 feet deep. That said, unlike some reservoirs, the water levels of Guntersville Lake barely fluctuate throughout the year, averaging just 2 feet per year. Therefore, the lake maintains a storage capacity of around 1,049,000 acre feet year-round.

History of Guntersville Lake

Prior to the arrival of European settlers, numerous native tribes lived along and around the Tennessee River. Notable tribes include the Cherokee, Chickasaw, and Muscogee, all of which belonged to the unofficial group the Five Civilized Tribes. For hundreds of years, these tribes lived and hunted on the lands where Guntersville Lake now resides. Before the creation of the lake, the largest archeological project in the state found dozens of tribal sites in the area. Unfortunately, most of these sites now rest at the bottom of the lake. 

By the early 19th century, authorities and residents of the Tennessee River Valley faced numerous obstacles. The canals on the river were narrow, and the traffic on the river had become unbearable. Moreover, frequent floods affected agricultural yields from nearby farms and the viability of residential communities. However, it took nearly 100 years before authorities came up with a long-term solution to these problems. In 1933, President Franklin D. Roosevelt signed the Tennessee Valley Authority Act. The act provided the funds to develop nearly 640 miles of the Tennessee River. Proposed projects included 9 dams along the river and the creation of numerous reservoirs and canals to control flooding, generate power, and improve the irrigation of farmland.

Construction of the Guntersville Dam began on December 4, 1935 and finished on January 17, 1939. The dam measures 94 feet high and 3,979 feet long. Today, Guntersville Dam generates approximately 140,400 kilowatts of electric energy. The dam also features a navigation lock that can move watercraft up to 45 feet long between Guntersville Lake and Wheeler Lake. The Tennessee Valley Authority continues to own and operate the dam to this day.  

Guntersville Lake and Guntersville Dam both get their name from the nearby city of Guntersville, Alabama. The city in turn gets its name from John Gunter, the founder of Guntersville and great-grandfather of the famous American humorist, Will Rogers. Gunter operated a successful salt mine in the area in the late 18th and early 19th century. In order to expand his mining operation, Gunter married the daughter of a nearby Cherokee tribe that lived on the land he wanted. Over the years, a town grew next to his mine. Originally known as Gunter’s Ferry and then Gunter’s Landing, the town changed its name to Guntersville in 1854. Today, the town features numerous lakefront properties and serves as the county seat of Marshall County.
