Overview
editConstruction of the concrete-faced rock-filled dam began in 2006, before it was officially approved in December 2010 and impounded in 2016. The power station was fully operational in December 2017.[2][a]
The dam wall is 240 metres (790 ft) high and 1,697 metres (5,568 ft) long. When full, the resultant reservoir, has a capacity of 1,075 gigalitres (872,000 acre⋅ft).[4][5] In July 2009, a landslide at the construction site killed four people while causing damage and temporarily blocking the river.[6]
