The Wunonglong Dam is a gravity dam situated on the Lancang (Mekong) River in Weixi Lisu Autonomous County, Yunnan of Yunnan Province, China. The primary purpose of the dam is hydroelectric power production. Construction on the dam began in 2010 and the river was diverted around the foundation in November 2014. In 2016, construction began on the main dam, which was subsequently completed in 2017.
