The Andong Dam is an embankment dam on the Nakdong River, 4 km (2 mi) east of Andong in Gyeongsangbuk-do province, South Korea.

The purpose of the dam is flood control, water supply and hydroelectric power generation. Construction of the dam began in 1971 and was complete in 1976.[2] The 83 m (272 ft) tall rock-fill, central clay core dam withholds a reservoir of 1,248,000,000 m3 (1,011,770 acre⋅ft) and provides water to an 90 MW pumped-storage power station. The lower reservoir (afterbay) for the power station is created by a 20 m (66 ft) high and 238 m (781 ft) long weir.[3][4] The power plant is operated by the Korea Hydro and Nuclear Power (KHNP) organisation.[5]
