The Liuxihe Dam is an arch dam on the Liuxi River in Conghua District, Guangzhou, Guangdong Province, China. The main purpose of the project is hydroelectric power generation with additional purposes of flood control and irrigation. The dam is 78 metres (256 ft) tall and was constructed between 1956 and 1958.
In September 1955, planning for dams in the Liuxi River basin began and by January 1956, plans for the Liuxihe Dam were complete. In August 1956, construction on the dam began and excavation commenced the next month and continued until April 1957, removing 680,000 cubic metres (24,013,973 cu ft) of rock and material. The same month that excavation was complete, concrete placement began and continued until September 1958. Earlier in August, the first generator was placed online and the rest were operational by the end of 1958. Originally, the dam supported 4 × 10.5 MW generators but in 1993, they were upgraded to 12 MW each.[1]
