The following table lists the largest man-made dams by volume of fill/structure. By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list.
Hirakud Dam is built across the Mahanadi River, about 10 kilometres (6.2 mi) from Sambalpur in the state of Odisha in India. It is the longest earthen dam in the world. Behind the dam extends a 55 km (34 mi) long lake, Hirakud Reservoir .
The dam, measuring 185 meters in height and 2,309 meters in width, significantly surpasses Brazil’s 12,600 MW Itaipu facility and is one of the world's largest hydroelectric plants. [13] Each of the main water turbines, state-of-the-art at their installation, [14] has a capacity of 700 MW.
The Three Gorges Dam in Hubei, China, has the world's largest instantaneous generating capacity at 22,500 MW of power. In second place is the Baihetan Dam, also in China, with a capacity of 16,000 MW. The Itaipu Dam in Paraguay and Brazil is the third largest with 14,000 MW of power.
The list below largely ignores many natural lakes that have been augmented with the addition of a relatively minor dam. For example, a small dam, two hydroelectric plants, and locks on the outlet of Lake Superior make it possible to artificially control the lake level.
The tallest embankment dam and second tallest dam in the world is the 300 m (984 ft) Nurek Dam in Tajikistan. The tallest gravity dam is the 285 m (935 ft) high Grande Dixence Dam in Switzerland. The tallest natural dam, the 567 m (1,860 ft) Usoi Dam in Tajikistan, is 262 m (860 ft) taller than the tallest existing man-made one.
The dam is 214 m (702 ft) tall, 1,314 m (4,311 ft) long and contains 2,200,000 m 3 (2,900,000 cu yd) of concrete, making it the largest dam of its type in the world. [2] [4] The dam was named after Daniel Johnson Sr., the 20th Premier of Quebec, responsible for starting the project while serving as a minister in Duplessis's government.
The Adam T. Bower Memorial Dam (formerly known as the Sunbury Fabridam) is the world's longest inflatable dam. [2] The dam is located just below the confluence of the Western and Main Branches of the Susquehanna River, in Upper Augusta Township, between the town of Shamokin Dam and the city of Sunbury, Pennsylvania. The dam is 2,100 feet (640 m ...
