Hantangang Dam
The 928th tallest dam in the world
The Hantangang Dam is a gravity dam on the Hantan River in Yeoncheon County, Gyeonggi Province, South Korea. Construction on the dam began in 2007 and was completed in 2015. The primary purpose of the dam is flood control : it was proposed in 1998 after a series of floods in the late 1990s that killed 128 people, displaced over 31,000 and caused about US$900 million in property damage. Initially designed as a multi-purpose project, the design was changed solely to flood control in 2006 due to the concerns of residents upstream. It is being implemented by Korea Water Resources Corporation (K-water).
