The Martin Project is located on the Tallapoosa River in Alabama in Tallapoosa, Elmore and Coosa Counties.
The Martin Dam Project includes a dam, powerhouse, impoundment, and recreation facilities, described in more detail below.
The project includes Lake Martin, an approximately 31-mile-long, 41,450-acre reservoir at the maximum full pool elevation of 491 feet mean sea level (msl). Lake Martin is formed by a 2,255-foot-long concrete gravity dam and earth dike section (Martin Dam), which includes a 720-foot-long gated spillway section with 20 vertical lift spillway gates, a 255-foot-long concrete gravity non-overflow section, an approximately 1,000-foot-long earth embankment on the left abutment, and a 280-foot-long concrete gravity intake structure with 12 intake gates fitted with trashracks. There are two, 450-foot-long transmission lines that lead from the powerhouse to the project’s switchyard; and appurtenant facilities include a low auxiliary dam that forms a stilling basin for spillway discharges, and a powerhouse access road.
