Sup'ung Dam

The Sup'ung Dam (traditional, simplified), also referred to as the Shuifeng Dam and originally the Suihō Dam, is a gravity dam on the Yalu River between Kuandian Manchu Autonomous County, Liaoning Province in China and Sakju County, North Pyongan Province in North Korea. The reservoir is called Supung Lake. The dam was constructed by the Japanese between 1937 and 1943 in order to generate electricity and has been repaired and renovated several times throughout the years, mainly due to damage from the Korean War and spillway damage from flooding. During the Korean War, the dam was bombed by the United Nations Command three separate times in order to disrupt power generation for the North Koreans. At the time of its completion, the dam was the largest in Asia, and power station was third-largest (after Hoover Dam and Wilson Dam) hydroelectric power station in the world. It is still the largest hydroelectric power station on the Yalu (Amnok) River. Power produced at the dam's main 630 MW power station is evenly shared between China and North Korea. The dam is featured on the national emblem of North Korea.
