Three Gorges people mentioned it once again, but after repeated discussions and investigations, it was again postponed. On March 6, 1992, a feasibility report was presented at the 5th Session of the 7th National People's Congress (NPC) for discussion and resolution. On April 3 of that year, 2,633 NPC members, one-third of the whole body, voted for the Resolution on the Development of the Three Gorges Project, and this was unprecedented in the voting history of the People's Republic of China. The Three Gorges Project officially began on December 14, 1994. The Three Gorges Dam was constructed at Sandouping (), Yichang ()
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
