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.[1][2] 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.[3] It is being implemented by Korea Water Resources Corporation (K-water).
