List of tallest dams in China: The tallest dams in China are some of the tallest dams in the world.  Nearly 22,000 dams over 15 m in height – about half the world's total – have been constructed in China since the 1950s.  Many of the tallest are located in the southwestern part of the country (Guizhou, Sichuan, Yunnan) on rivers such as the Mekong, the Yangtze, and its upper stretch (Jinsha River) and tributaries (Yalong, Dadu, Min and Wu).  The Yellow River in the western part of the country also hosts several among the tallest.  Purposes for these high structures include flood control, irrigation and, predominantly, hydroelectric power.  While beneficial, many throughout the country have been criticized for their effects on the environment, displacement of locals and effect on transboundary river flows.  Currently, the country's and world's tallest, Jinping-I Dam, an arch dam 305 m high, is located in Sichuan.  The tallest embankment dam in China is the 261 m Nuozhadu Dam in Yunnan.  The country's highest gravity dam is Longtan Dam at 216.2 m , which can be found in Guangxi.  At 233 m , Shuibuya Dam in Hubei is the world's tallest concrete-face rock-fill dam.  In Sichuan, the government is constructing the 312 m tall Shuangjiangkou Dam which, when complete, will become the world's tallest dam.
