The Danjiangkou Dam is a concrete gravity dam on the Han river near Danjiangkou in Hubei Province, China. The 162 m (531 ft) dam is part of the South-North Water Transfer Project and was heightened to 176.6 m (579 ft) in order to increase reservoir capacity. The original dam was constructed between 1958 and 1973 and heightened from 2005 to 2009.
The original dam was 97 m (318 ft) tall and 2,494 m (8,182 ft) long. Since its heightening, the dam is now 111.6 m (366 ft) tall and 3,442 m (11,293 ft) long. The increase in height will add 11,600,000,000 m3 (9,404,273 acre·ft) to the reservoir's capacity bring it to 29,050,000,000 m3 (23,551,218 acre·ft). Currently, the reservoir has a capacity of 17,450,000,000 m3 (14,146,945 acre·ft).[1][2][3]
The dam's power plant also contains 6 x 150 MW turbine generators for an installed capacity of 900 MW. This will increase with the heightened reservoir.[4]
