The Danjiangkou Dam (Chinese: 丹江口大坝; pinyin: Dānjiāngkǒu Dàbà) is a concrete gravity dam on the Han river near Danjiangkou in Hubei Province, China. The original dam was constructed between 1958 and 1973. The dam creates a large Danjiangkou Reservoir.

In the 21st century, the Danjiangkou Dam became part of the South-North Water Transfer Project. In 2005-2009, its height was raised in order to increase the reservoir's capacity.
Heightening
Originally, the 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 original crest elevation was 162 m (531 ft) and is now 176.6 m (579 ft). 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]

Die Danjiangkou-Talsperre (.mw-parser-output .Hans{font-size:110%}丹江口水利枢纽工程, Danjiangkou shuili shuniu gongcheng – „Danjiangkou-Schlüsselprojekt für den Wasserbau“) ist ein 1958 begonnenes und 1974 fertiggestelltes, sogenanntes Schlüsselprojekt für den chinesischen Wasserbau in Danjiangkou in der Provinz Hubei. Die Talsperre liegt am Oberlauf des Han Jiang (ein linker Nebenfluss des Jangtsekiang) und an dessen größten Nebenfluss Dan Jiang (丹江). Der Stausee hat eine Speicherkapazität von 29,05 Milliarden Kubikmetern (vor der Erhöhung 20,89 Mrd. m³).[1] Die Höhe der Gewichtsstaumauer beträgt seit 2009 176,6 Meter (vor der Erhöhung 162 m). Neben Schleusen gibt es auch ein Schiffshebewerk mit einer Hubhöhe von 50 m für Schiffe bis zu 450 t.- [en] Danjiangkou Dam
