The Supung Dam (also Sup'ung, Shuifeng, Sui-ho) near Sinŭiju on the Yalu River is on the border between the People's Republic of China and North Korea .
Construction began in 1941 when Korea was a province of Japan and was the fourth tallest dam on earth at the time .
The dam is a 106 m high and 853 m long gravity dam made of concrete. It is 97 m wide at the base and 18 m wide at the crown. The reservoir has a capacity of 14,670 million cubic meters (20,000 million m³ are also given). The area of the reservoir is given as 274 or 284.5 km².
The hydropower plant has six turbines with 100 MW each . It supplies large parts of North Korea and the Lüshunkou (Port Arthur) and Dairen regions in northeast China with energy.
On June 23, 1952, the dam was attacked and partially destroyed by the Americans in the Korean War, along with three other dams . By then, it had supplied 90% of North Korea's electricity, so North Korea's electricity supply was paralyzed for two weeks.
