The main purpose of the project is hydroelectric power generation with additional purposes of water regulation and irrigation. It creates the uppermost or head reservoir on the Beipan and was constructed between 2003 and 2008. ConstructionConstruction on the dam began in May 2003 and the river was diverted in October 2004.[1] Reservoir filling began in 2007 and by 2008, the dam and power plant were complete. On June 28, 2010, a landslide in the area of the dam that killed 99 locals was believed to be caused by seismic effects from the reservoir.[2] SpecificationsThe dam is {{Convert|200.5|m|ft|0}} tall and {{Convert|410|m|ft|0}} wide and composed of roller-compacted concrete. It also contains three spillway chutes on its surface. Each spillway is controlled by a {{Convert|16|m|ft|0}} wide and {{Convert|20|m|ft|0}} tall floodgate and they have a combined maximum discharge of {{Convert|9857|m3/s|ft3/s|0}}. The dam also contains a bottom outlet works for draining the reservoir which a maximum discharge capacity of {{Convert|799|m3/s|ft3/s|0}}.[1] See also{{stack|{{Portal|China|Water|Renewable energy}}}}
