This is a list of the tallest dams in the world over 135 m (443 ft) in height. Currently, the tallest dam in the world is the Jinping-I Dam, an arch dam in China at 305 m (1,001 ft) high. The tallest embankment dam is the 300 m (984 ft) high Nurek Dam in Tajikistan, which was built in Soviet-era. It is also the second tallest dam in the world. For gravity dams, the tallest is the 285 m (935 ft) high Grande Dixence Dam in Switzerland. When completed, the 335 m (1,099 ft) tall Rogun Dam also in Tajikistan could be the tallest, depending on the chosen design. Next in line are the 325 m (1,066 ft) Bakhtiari Dam currently under construction in Iran and the 312 m (1,024 ft) Shuangjiangkou Dam currently under construction in China. Natural landslide dams are also quite competitive in height, but are not listed here. In particular, the highest natural dam, Usoi Dam, is higher than the highest existing man-made one.
