Danjiangkou Dam
Encyclopedia
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.
's capacity bring it to 29050000000 cubic metre. Currently, the reservoir has a capacity of 17450000000 cubic metre.
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.

Heightening
The original dam was 97 m (318 ft) tall and 2494 m (8,182 ft) long. Since its heightening, the dam is now 111.6 m (366 ft) tall and 3442 m (11,293 ft) long. The increase in height will add 11600000000 cubic metre to the reservoirReservoir
