The Longma Dam (simplified Chinese: 龙马大坝; traditional Chinese: 龍馬大壩; pinyin: lóng mǎ dà bà) is a concrete-face rock-fill dam on the Lixian River in Mojiang Hani Autonomous County, Pu'er City, Yunnan Province, China. The primary purpose of the dam is hydroelectric power generation and it is the fourth of seven dams in the Lixian River Project. It supports a 240 MW power station. Construction on the dam began on 23 December 2003 and the reservoir began to impound 20 July 2005. In July 2007, the first generator was commissioned and the last two were in December 2007. The project was complete in June 2008 at a cost of US$332 million. The 135 m (443 ft) tall dam withholds a reservoir with a 590,000,000 m3 (478,321 acre·ft) capacity.[1]
