Extended data:

The Three Gorges Dam Project consists of two parts: the main project and the diversion project. The dam is a concrete gravity dam with a total length of 3,035 m, an elevation of 185m, a normal water level of 175m, and a total storage capacity of 39.3 billion cubic meters, of which the storage capacity of the flood control reservoir is 22,654.38+500 million cubic meters, which can resist the once-in-a-century flood.

There are 32 hydroelectric generating units with a single capacity of 700,000 kilowatts and two power stations with a power supply capacity of 50,000 kilowatts installed on the left and right banks of the Three Gorges Dam, with a total installed capacity of 22.5 million kilowatts ranking first in the world. The Three Gorges Dam won the world record for the largest water control project in world record association.

According to the inundation treatment plan of the Three Gorges Reservoir, the total area is about 79,000 square kilometers, and the inundated cultivated land 1.94 million hectares, involving immigrants1.71.5 million people. The whole reservoir area plans to resettle 405,000 rural migrants, 322,000 people in the county and 83,000 people outside the county during the flood. It is planned to relocate 440,000 people (65,000 in Hubei Province and 375,000 in Chongqing) and 322,000 people in the county (40,000 in Hubei Province and 282,000 in Chongqing).

There are 129 flooded towns in the Three Gorges reservoir area, including two medium-sized cities, Wanzhou (originally Wanxian City, prefecture level) and Fuling City (prefecture level), and more than a dozen small cities, which will generate1130,000 immigrants. Immigration is the biggest difficulty of the Three Gorges Project, and 45% of the total investment is used for resettlement.
