Hwacheon Dam
The 928th tallest dam in the world
Hwacheon Dam is a concrete gravity dam on the North Han (Pukhan) River in Hwacheon County, Gangwon-do Province, South Korea. The dam was completed in 1944 as a primary source of electricity in southern Korea. It was the focal point of a raid during the Korean War and also provides flood protection from North Korea's Imnam Dam upstream.
