In 1995 the report was reviewed and approved by the Chinese government. Three years later in 1998, a consortium to fund and construct the dam was organized. In 1999, preliminary construction (roads, bridges, river diversion) began. Official construction on the dam started on 1 January 2002. The river was diverted by November 2003 and concrete pouring began in 2005. The river diversion was closed and the reservoir began to impound in November 2007.〔 The first generator was commissioned in September 2009 and the dam was complete in March 2010.〔 The last of the six generators went operational on 22 August 2010. The creation of the dam's reservoir submerged of land and displaced 32,737 people.〔
