The Dongjiang Dam is an arch dam on the Lishui River 140NaN0 southwest of Zixing in Hunan Province, China. The dam was constructed between 1978 and 1992 and supports a 500 MW hydroelectric power station. The dam also provides for flood control, navigation and water supply. The dam's first generator was operational in 1987 and the reservoir, Dongjiang Lake, forced the relocation of 52 thousand people.[2]
The Dongjiang is a 1570NaN0 tall and 4380NaN0 long variable-radius arch dam. The dam is 70NaN0 wide at its crest, 350NaN0 at its base and has a curve radius of 302.30NaN0. Situated at the head of a 47190NaN0 catchment area, the dam withholds a reservoir of up to 95650000000NaN0 of water. The dam's power station lies at its base and contains four 125 MW Francis turbine-generators. The height of the dam affords each generator an effective hydraulic head of 118.50NaN0. The dam is also equipped with a boat/lumber lift.[2] [3]
