The Longjiang Dam is an arch dam on the Long River (upper of Shweli River) near Mangshi in Dehong Prefecture of Yunnan Province, China. It is a multiple-purpose project aimed at flood control, irrigation and hydroelectric power generation. Its reservoir has a storage capacity of 1,217,000,000 m3 (986,638 acre⋅ft), of which 679,000,000 m3 (550,474 acre⋅ft) is reserved for river these purposes. The dam's power station is located on its left bank and contains three 80 MW Francis turbine-generators for a total installed capacity if 240 MW.[1][2] Construction on the project began on 28 November 2006 and all generators were commissioned in 2010.[3]
