The Lianghekou Dam (meaning: "mouth of two rivers") is a concrete-face rock-fill dam currently under construction on the Yalong River in Yajiang County, Sichuan Province, China. The dam is located at the confluence of the Yalong, Xianshui and Qingda Rivers.[1] The 295 m (968 ft) tall dam will be the highest embankment dam in the country and support a 3,000 MW power station.[2] Studies for the dam were completed between 2005 and 2009 with preliminary construction beginning that year.[3] Major works on the dam officially began in October 2014. The first generator is expected to be commissioned in 2021 and the project complete in 2023.[4]
