Here is the list of top 10 longest Dams in the world of 2017-18. Dams have been built by human beings for a long time to stop the flow of water and divert it for agriculture but these traditional dams were much smaller in size as compared to the large structures we see today. Dams are constructing for the Purpose of Irrigation, Flood Control, Power Generation, Water Supply, Land Reclamation, Water Diversion, Navigation, Recreation and Aquatic Beauty. The height of the dam depends on many factors like the surrounding topography, the proposed purpose of the dam, the flow of the river and rainfall pattern in the area. The Following largest Dams in the World are listed in Top 10 by Volume of Structure.
10. Robert-Bourassa Dam, Canada
The Robert-Bourassa dam is located 117.5 kilometers (73.0 mi) from the mouth of the La Grande River, in the transition zone between the Laurentian Plateau (the elevated Canadian Shield) and the coastal plain.

By 1978, the capacity had been upgraded to 2065 MW, generated by ten turbines.
4. Daniel Johnson Dam, Canada
The dam is composed of 14 buttresses and 13 arches and is 214 km (133 mi) north of Baie-Comeau in Quebec, Canada. The dam was constructed between 1959 and 1970 for the purpose of hydro electric power production and supplies water to the Manic-5 and Manic-5-PA powerhouses with a combined capacity of 2,596 MW. The dam is 214 m (702 ft) tall, 1,314 m (4,311 ft) long and contains 2,200,000 m3 (2,900,000 yds) of concrete, making it the largest dam of its type in the world.
3. Akosombo Dam, Ghana
The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority. The construction of the dam flooded part of the Volta River Basin and led to the subsequent creation of Lake Volta.The dam is 660 m (2,170 ft) long and 114 m (374 ft), comprising a high rock-fill embankment dam. It has a base width of 366 m (1,201 ft) and a structural volume of 7,900,000 m3 (10,300,000 yd). The reservoir created by the dam, Lake Volta, has a capacity of 148 km3 (120,000,000 acre·ft) and a surface area of 8,502 km2 (3,283 sq mi).
2. Bratsk Dam, Russia
