Construction began in 1986. The dam was immediately seen as a threat by the South Korean government. The Bukhan River is a tributary of the Han River, and war scenarios foresaw North Korea releasing flood waters that could engulf the South Korean capital of Seoul. Though fears of a "water attack" have diminished, 2002 satellite photos of cracks in the North Korean dam caused fears it could collapse following heavy rains. In September 2005, without warning, North Korea released a massive amount of water from a dam, causing large floods in South Korea.
To protect itself against the perceived threat, South Korea built the Peace Dam across the border, 22 miles to the south.
Since Imnam Dam was built, water inflow to the Han River has decreased by 12 percent. This has caused environmental problems and water shortages in the Seoul metropolitan area.
Imnam Dam is 710 meters wide, 121.5 meters high, and has a claimed capacity of 2.62 billion tons of water.

Like the two Koreas, the two dams are twin brothers, born at the same time, facing each other across DMZ
