Lake Martin is located in Tallapoosa, Elmore and Coosa counties in Alabama, USA. Encompassing more than 40,000-acres and over 800 miles of wooded shoreline Lake Martin was created by the construction of Martin Dam on the Tallapoosa River. The Martin Dam powerhouse is used to generate hydroelectric power for the Alabama Power Company. Construction on Martin Dam began in 1923 and was completed in 1926, creating what was at that time the largest man-made body of water in the world. Originally known as Cherokee Bluffs for the geological formation upon which it was built (which recognized the historic indigenous people of the area), the dam was renamed in 1936 in honor of Thomas Martin, the then-president of Alabama Power Company. Alabama Power and Russell Lands own the majority of the shoreline.
