Xiaonanhai Dam Xiaonanhai Dam The Xiaonanhai Dam was a proposed dam on the Yangtze River in Chongqing, China. It was to have an associated 1,760 MW hydroelectric power station. Preliminary construction on the dam began on 29 March 2012 and earliest completion was expected in 2019. However, it was cancelled in March 2015 due to environmental concerns. The project, under responsibility of the Chongqing municipal government, was initiated under the stewardship of Bo Xilai prior to his fall from grace in 2012. The dam was to be constructed by China Three Gorges Corporation 40 km upstream of the city, and 700 km
Three Gorges Dam spillway gates of the dam might pose a risk of cavitation, similar to that which severely damaged the poorly designed and cavitating spillways of the Glen Canyon Dam in the US state of Arizona, which was unable to properly withstand the Colorado river floods of 1983. However, 163,000 concrete units of the Three Gorges dam all passed quality testing and the deformation was within design limits. An experts group gave the project overall a good quality rating. In order to maximize the utility of the Three Gorges Dam and cut down on sedimentation from the Jinsha River, the upper course
