In 1980, work on the dam continued faster. The National People's Congress voted in 1992 for the dam. The dam was accepted by the government, and on December 14, 1994, construction began. In 2009, the dam began to make hydroelectricity. Some new plans, such as a set of 6 new power generators under construction, became operational in the year 2011. The reservoir filled to capacity at the end of 2008.
