Biggest Flood Control Benefit in the World

Although the TGP Reservoir is not the reservoir with the biggest capacity in the world, its reserved flood control capacity can help cut flood peak by 27,000 33,000 m3/s, the biggest for a water conservancy project in the world.

When the TGP is completed, the flood control standard of the middle and lower reaches of the Yangtze, especially the Jingjiang Section, will be largely upgraded from the present level of preventing under-10-year floods to that of preventing 100-year floods. So 15 million people and 1.5 million hectares of farmland in the Jianghan Plain are relieved from flood threats, and devastating plagues of massive death caused by big floods are avoided.
