The Three Gorges Dam 长江三峡大坝


This photo displays a model of China's Three Gorges Dam. The controversial project includes the 2300 meter long dam (which runs across the center of the model); the world's largest hydro-electric station; and massive locks which allow access for navigation up-river and down-river of the dam. The completed project was 17 years under development (1994-2009) and cost the equivalent of 31 billion US dollars.

The Chinese government reports that 1.3 million people were relocated before and during construction. Touted benefits (outweighing the mass relocation of families) include flood control, protecting 15 million people and 1.5 million hectares of arable land downriver; maintaining water supply and irrigation potential for areas downriver during the dry season; and, the production of electricity (saving 57 million tons of coal).

The model depicts the expansive reservoir in the foreground, the Yangtze continuing east to Shanghai and its eventual outlet into the East China Sea, and the locks (on the left) which allow for barge and boat traffic in both directions.

It would never be possible to take such a "virtual" photo except from an airplane, but not from where tourists are permitted to view the dam.
