Bashan Dam

The Bashan Dam is an embankment dam on the Renhe River located 15 km (9 mi) northwest of Chengkou County's seat in Chongqing, China. The primary purpose of the dam is hydroelectric power generation and it supports a 140 MW power station containing two 70 MW Pelton turbine-generators. It is a concrete-face rock-fill type with a height of 155 m (509 ft); creating a reservoir with a capacity of 315,000,000 m3 (412,004,445 cu yd). The dam is located before a bend in the river and diverts water through a 2,181 m (7,156 ft) long headrace tunnel that leads to the power station.[2] Construction on the project began in 2005, the river was diverted by 2006 and the generators operational in 2009.[3][4]
