(3) Bhakra Dam Explanation: Currently, the tallest dam in the world is the Nurek Dam, an embankment dam in Tajikistan at 300 m high. The tallest arch dam is the recently completed 292 m high Xiaowan Dam in China. For gravity dams, the tallest is the 285 m high Grande Dixence Dam in Switzerland. When completed, a 335 m tall Rogun Dam also in Tajikistan could be the tallest, depending on the chosen design. Next in line is the 312 m Shuangjiangkou Dam currently under construction in China. Natural landslide dams are also quite competitive in height but not listed here.
