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. The 295 m (968 ft) tall dam will be the highest embankment dam in the country and support a 3,000 MW power station. Studies for the dam were completed between 2005 and 2009 with preliminary construction beginning that year. 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.
When the dam's reservoir fills, it will force the relocation of over 4,900 people.
