The Yingzidu Dam is a concrete-face rock-fill dam on the Sancha River, a tributary of the Wu River, in Pingba County of Guizhou Province, China. The purpose of the dam is hydroelectric power production and flood control. It supports a 360 MW power station located just downstream. At a normal elevation of 1086m (3,563feet) the reservoir withholds 455000000abbr=onNaNabbr=on but it can hold up to 531000000abbr=onNaNabbr=on in the event of a flood. The spillway on the dam can also discharge up to 8386m3/s of water. Construction on the dam began on 8 November 2000 and on 10 April 2003 it began to impound its reservoir. On 22 May of the same year the first generator was commissioned, the second in August. By June 2004, the project was complete.[1] [2]
