Goupitan Dam
The Goupitan Dam (simplified Chinese: 构皮滩大坝; traditional Chinese: 構皮灘大壩; pinyin: Gòupítān Dàbà) is an arch dam on the Wu River, a tributary of the Yangtze River in Guizhou Province, southwest of China. The dam's hydroelectric facility will operate on five turbines, each with a hydroelectric generating capacity of 600 MW, for a total of 3,000 MW. Constructions began on in 2003 and the first generator was operational in June 2009.[1] All works were completed in 2011.[2][3][4]

By mean of this ship-lift a water level difference of 199 meters is overcome by mean of 3 stage of lifting, the 2nd stage alone being 127 meters, more than the overall high of the Three Gorges dam.
