Created by the construction of the Thomas Wesley Martin Dam, Lake Martin (not to be confused with Logan Martin Lake) on the Tallapoosa River covers approximately 40,000 acres when the reservoir is full and has more than 700 miles of shoreline, making it one of the largest manmade lakes in Alabama. At the time of its construction, it was the largest manmade lake in the world. The Thomas Wesley Martin Dam, which stopped the flow of the Tallapoosa River just southwest of Dadeville, is one of several built on the Tallapoosa during the first half of the twentieth century. The dam and lake are important economic and recreational centers for the state, providing boating, fishing, and other opportunities to visitors and 154,200 kilowatts of hydroelectric power.

Land clearing began in July 1923, and tracks were laid from the nearest railhead at Kent so supplies could reach the isolated construction site. Through its construction company, Dixie Construction, Alabama Power built a complete village for workers, including housing, a mess hall, a commissary, a recreation hall, and a hospital. The dam included 431,000 yards of concrete and was completed and the gates closed in 1926; however, the lake did not fill completely until heavy rains on April 23, 1928, forced the company to open several of the 20 floodgates for the first time. The total floodgate capacity is 3,016,000 gallons per minute. In 1926 the dam was named for Alabama Power president Thomas Wesley Martin but was not dedicated officially until 1936.

Lake Martin is fed by a watershed that encompasses 3,000 square miles in east-central Alabama at the end of the southern Piedmont Upland physiographic section. Kowaliga Creek, Big and Little Sandy Creeks, and Blue Creek join the Tallapoosa River north of the dam and are important tributaries. The lake is 490 feet above sea level at full capacity, but its level fluctuates to accommodate seasonal rainfall and to maintain hydroelectric power generation in the dry season. Lake Martin is crossed by the Central of Georgia railroad bridge to the north and by three vehicular bridges, including a four-lane bridge on U.S. Highway 280 east of Alexander City. Bridges also cross Kowaliga Creek and Blue Creek. Kowaliga, a Creek Indian name, was made famous by Alabama country music star Hank Williams Sr. in his song "Kaw-Liga," about the legend of a wooden Indian statue. Shortly after Williams' death in 1953, a wooden Indian was placed at the fish camp and café on the south side of the Kowaliga Creek Bridge, a place Williams knew well and often visited.
