The history of such projects in China has two different aspects. The country has been controlling and harnessing water for centuries—no other civilization on earth has such a long and successful history of turning rivers to man’s use. The development of central Sichuan province was originally sparked by the construction of Dujiangyan, a brilliantly designed irrigation project that was constructed twenty-three centuries ago and even today still functions perfectly, turning the Chengdu Basin into one of the most fertile rice-growing regions in the country. Even the Yangtze has been tamed before, albeit on a much smaller scale; the Gezhou Dam was completed in 1981 on a site downstream from the location of the current project.
But there is also the history of Henan province, where heavy rains in 1975 caused sixty-two modern dams to fall like dominoes, one after another, and 230,000 people died. Although the scale of that particular disaster was unique, the poor engineering was less unusual: 3,200 Chinese dams have burst since 1949. In this [= 20th] century, the failure rate of Chinese dams is 3.7 percent, compared to 0.6 percent in the rest of the world.
