The Sup'ung Dam, 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 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 spillway damage from flooding.

The Yalu River or Amnok River is a river on the border between China and North Korea. Together with the Tumen River to its east, and a small portion of Paektu Mountain, the Yalu forms the border between China and North Korea. Its valley became the scene of several military conflicts in the past centuries.
It borders North Korea to the south, borders Russia to the northeast and borders China to the north.
