Three Gorges Dam: They don’t come any more colossal than China’s massive hydroelectric dam spanning the Yangtze River. Visitors to the U.S.’s Hoover Dam may wish to know that the Three Gorges is more than five times as large, at 2,335 meters in length and 185 meters high—over 600 feet. It began doing its damming job in 2003, but won’t be fully operational until 2009. Over 1 million people are expected to be displaced by the rising waters.
