Lake Martin is located in Tallapoosa, Elmore and Coosa counties in Alabama. It is a 44,000-acre (178 km2) reservoir with over 750 miles (1,200 km) of wooded shoreline. Lake Martin is a reservoir, enlarged 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 human-made body of water in the world. Originally known as Cherokee Bluffs for the geological formation upon which it was built, the dam was renamed in 1936 in honor of Thomas Martin, the then-president of Alabama Power Company.[2] Alabama Power and Russell Lands own some of the shoreline.
Tourism
[edit]The third largest lake in Alabama, Lake Martin, is a popular recreation area for swimming, boating, water skiing, camping, and golfing. Many waterfront neighborhoods and luxury homes are located on Lake Martin. The cities of Alexander City, Dadeville, Jackson's Gap, and Eclectic are nearby.
Lake Martin hosts many events throughout the year, including fishing tournaments, a 4 July fireworks event, the Alexander City Jazz Festival (an annual event every June in downtown Alexander City), and entertainment at the Route 63 Lake Martin Amphitheater.
Lake Martin includes many popular attractions, including eagle nests, sand beaches, restaurants, camping areas and popular islands such as Goat Island.[3] The lake has several landmarks, such as the Smith Mountain Fire Tower,[4] Kowaliga Bridge, and several marinas, but perhaps the most recognized landmark on the lake is Chimney Rock, a large rock formation that resembles a chimney. Although Chimney Rock is located several hundred yards away, the formation most people call Chimney Rock is actually Acapulco Rock. The area was the Tallapoosa River gorge before Martin Dam was built, and the water is more than 150 feet (46 m) deep. The spot is visited by thousands of boaters yearly, who park in front of "The Rock" to watch people climb up 60 feet (18 m) and jump off into the water. In July 2006, a teenager died after jumping from the rock.[5]
Alabama has a lake of a similar name, the Logan Martin Lake on the Coosa River. Lake Martin and Logan Martin Lake are not part of the same river system.
Islands on Lake Martin
[edit]Small islands are popular spots on Lake Martin:
- Cemetery Island - A small county graveyard from before the construction of Martin Dam is located on what is now a tiny island in Lake Martin. About 30 by 30 yards (27 m) around, it is in the Bay Pine area.
- Chimney Rock Island - Chimney Rock Island has long been a famous landmark on Lake Martin. Its name came from a tall rock resembling a chimney that protrudes from the top of the island.
- Acapulco Rock Island - Acapulco Rock Island is adjacent to Chimney Rock Island at the Tallapoosa River Gorge. It is often mistaken for Chimney Rock.
- Deer Island - A small island located less than half a mile northwest of Kowaliga Marina. At low water levels, it is connected to the mainland by a land bridge. Deer often cross to the island during the winter when the water levels are lowest and become trapped when the water level rises. Its shore has wide banks of fine-grain sand and thus many residents dock boats on the islands.
- Doctor's Island - So named because a group of doctors used the island as a fishing base camp.
- Goat Island - Goat Island is north of Martin Dam. It has become the residence for a family of goats.
- Real Island - Not an island or distinct community, residents named it for "Real Island Road," which runs through it, and a nearby marina.
- Sand Island - Sand Island is a small island located between Willow Point and Kowaliga Marina. Over the years, erosion has taken its toll on the island, but rocks have recently been placed around the island to prevent it from being completely washed away. Boats frequently park on its sandy, shallow beach. It is likely the smallest island on the lake.
- Young's Island - The Young residence (of Young's ferry) was here and was destroyed by fire in the early 1990s. The foundation remains, and there are historic markers for the graves of the family's children.
- Weed Hill Island - Weed Hill is a small island almost directly across from the Pleasure Point Marina boat ramp. Although at one time it was much larger, erosion has reduced the landmass.
- Wood's Island - Wood's Island is a larger island, connected to the mainland by a land bridge during low water times. It has several trails for hiking. It can be found at the end of Young's Ferry Rd on the West side of the lake.
- Wilmarth's Island- only inhabited island on the lake.
Tornadoes
[edit]On April 27, 2011, an EF4 tornado ripped across Lake Martin. Several valuable houses and businesses were destroyed along its path. Some vehicles were carried over 100 yards. The tornado resulted in seven deaths across the region. Its path through Elmore, Tallapoosa, and Chambers counties was 44.2 miles (71.1 km) long.[6]
Another tornado went through the northern side of the lake on January 12, 2023. The tornado was rated EF3; however, the maximum damage near the lake was rated EF2.[7]

Location and Physical Characteristics
Lake Martin is a reservoir located in Coosa, Elmore, and Tallapoosa counties in east-central Alabama, impounding the Tallapoosa River approximately 61 miles upstream from its junction with the Coosa River.[5] The lake borders communities including Alexander City, Dadeville, Jackson's Gap, and Eclectic, and lies within the Piedmont physiographic region characterized by rolling hills and forested terrain.[5] The reservoir extends about 31 miles upstream from Martin Dam, covering a surface area of 41,150 acres at full pool elevation of 491 feet above mean sea level.[5] [6] It possesses 880 miles of shoreline, predominantly wooded and irregular due to the pre-impoundment riverine topography.[5] The maximum depth reaches 155 feet near the dam, with an average depth of 41 feet across the basin.[5] [7] The storage volume at full pool totals 1,622,000 acre-feet, supporting seasonal fluctuations between summer (higher) and winter (lower) levels for hydropower and flood control operations.[8]Watershed and Water Levels
The watershed draining into Lake Martin encompasses approximately 3,000 square miles (7,800 km²) in east-central Alabama and extends into western Georgia, primarily along the Tallapoosa River basin.[3][9] This area includes upstream contributions from the Tallapoosa River and its tributaries, such as Hillabee Creek and Shoal Creek, which deliver runoff influenced by the southern Piedmont Upland physiographic region.[2] The drainage supports the reservoir's hydrology, with inflow varying based on regional precipitation patterns and upstream land use, though specific retention time averages around 190 days due to the lake's volume relative to inflow rates.[10] Water levels in Lake Martin are regulated by Alabama Power Company under a Federal Energy Regulatory Commission (FERC) license, balancing hydroelectric generation, flood control, recreation, and downstream water supply. The full summer pool elevation is maintained at 491 feet (150 m) above mean sea level from approximately March to August to support boating, fishing, and shoreline activities.[3][11] Drawdown begins around September 1 and continues through November 30, reducing levels to a winter pool of 484 feet (148 m) to provide flood storage capacity ahead of seasonal rains.[12][13] This rule curve is coordinated with the U.S. Army Corps of Engineers and can include temporary extensions or adjustments based on rainfall forecasts and inflow conditions, as evaluated annually.[3] Levels are monitored in real-time, with discharges managed via the dam's turbines and spillways to prevent uncontrolled flooding while optimizing power output.[3]History
Pre-Impoundment Era
The Tallapoosa River valley, which would later form the basin of Lake Martin, was originally inhabited by the Creek (Muscogee) Indians, who had established villages and utilized the river's resources for centuries prior to European contact.[14] The Creeks formed part of a broader alliance of river chiefdoms spanning the Tallapoosa, Coosa, and Chattahoochee valleys, engaging in agriculture, hunting, and trade along the waterway.[15] Following the Creek War of 1813–1814 and the subsequent Treaty of Cusseta in 1832, the Creek Nation ceded remaining lands in the region, leading to the forced removal of most indigenous populations via the Trail of Tears in the 1830s and the establishment of Tallapoosa County in 1832.[14] European-American settlement in the Tallapoosa County area began in the 1830s, with migrants primarily from the Carolinas, Georgia, and Tennessee establishing farms and small hamlets along the river.[16] The economy centered on agriculture, including cotton cultivation, livestock rearing, and subsistence farming, supplemented by river-based activities such as ferries, grist mills, and occasional gold prospecting tied to the broader Alabama gold rush of the 1830s.[17] By the late 19th and early 20th centuries, the valley remained predominantly rural, dotted with scattered communities like Susanna and Irma, where residents relied on the unimpounded Tallapoosa for transportation, fishing, and limited hydropower from small mills.[18] Cherokee Bluffs, a deep gorge with towering rock cliffs along the river, served as a notable natural landmark popular for picnics and camping in this era.[2] Post-Civil War, several African American communities emerged in the valley, including Kowaliga, founded by freedmen such as John Benson, a former slave, who developed farming operations and later supported educational efforts through his son William Benson's establishment of the Kowaliga Academic and Industrial School around 1895.[19] These settlements featured self-sustaining agriculture, churches, and schools, reflecting resilient post-emancipation economies amid sharecropping and tenant farming prevalent in rural Alabama.[20] By the early 1900s, the population density remained low, with dozens of small, unnamed hamlets and family homesteads vulnerable to eventual flooding; Alabama Power Company initiated land acquisitions as early as 1916, prompting gradual displacement of residents well before construction commenced.[2]Construction Period (1920s)
The construction of Martin Dam, which formed Lake Martin, was undertaken by the Alabama Power Company to generate hydroelectric power from the Tallapoosa River.[2] Work began in 1923, marking it as the company's largest construction project to date.[21] [22] Engineers designed the dam to impound water across approximately 44,000 acres, utilizing 431,000 cubic yards of concrete in its structure.[2] [5] Construction progressed through the mid-1920s, with the dam completed and gates closed in 1926, enabling initial power generation from the on-site powerhouse.[21] At that time, the resulting reservoir was the largest man-made lake in the world by surface area.[5] [2] Full impoundment was delayed by insufficient rainfall, with the lake reaching capacity only after heavy rains in April 1928 prompted the opening of floodgates for the first time.[23] The project was renamed Martin Dam in honor of Thomas Wesley Martin, a key executive at Alabama Power who oversaw its development.[2]Engineering and Power Generation
Dam Structure and Design
Martin Dam is a concrete gravity structure with an integrated earth dike section, designed to impound the Tallapoosa River for hydroelectric generation and flood control.[6] The main concrete portion spans 2,000 feet, achieving a maximum height of 168 feet, while the total embankment length, including the dike, measures approximately 2,255 feet.[24][5][25] The dam incorporates 431,000 cubic yards of concrete, poured during construction from 1923 to 1926 by Alabama Power's Dixie Construction subsidiary.[5][21] Key components include a 720-foot gated spillway with twenty vertical lift gates—each 30 feet wide by 16 feet high—capable of discharging up to 133,000 cubic feet per second at the full pool elevation of 491 feet mean sea level.[6] This spillway adjoins a 255-foot non-overflow section and feeds into a stilling basin to dissipate energy and reduce downstream scour.[6] The design also features four steel penstocks equipped with twelve intake gates protected by trashracks, facilitating controlled water flow to the turbines.[6] The integral powerhouse is a steel-frame edifice clad in brick and concrete, measuring 307 feet long, 58 feet wide, and 99 feet high, housing four vertical Francis turbines.[6] It is distinguished by intricate brickwork detailing and tiled flooring, hallmarks of early 20th-century industrial architecture employed by Alabama Power.[21] Chief engineer Oscar Thurlow oversaw the overall design, including the original spillgates, emphasizing durability and efficient power extraction from the river's gradient.[26]| Feature | Specification |
