Now that Three Gorges Dam has closed its gates, the stage is set for the Yangtze River to flood the Sichuan and Hubei provinces of China. The Dam will provide billions of kilowatts of electricity to the growing nation and as yet, unnumbered complications.
In 1992, despite widespread opposition, the National Peoples Congress approved the Three Gorges Project, with a third of the delegates opposing or abstaining from the proposal. Although ecologists, archaeologists, and human rights advocates openly criticized the Dams construction, the first stage of the 17 year-long projectbuilding the initial dam structurewas completed in November of 1997. In a speech at the damming ceremony, former President Jiang Zemin had this to say:
[The Dam] embodies the great industrious and dauntless spirit of the Chinese nation and displays the daring vision of the Chinese people for new horizons and better future in the course of their reform and opening-up.
On June 1st of this year, engineers completed the second phase of the Three Gorges Project. Nineteen of the Dams 22 gates were closed causing the level of the newly formed lake to rise over a 100 meters on the first morning of its operation, inundating hundreds of towns. By the projects completion in 2009, 365 towns in over 20 counties will be covered by the rising Yangtze River. The rising waters have already displaced over 700,000 people with officials predicting 1.2 million people to be relocated due to unforeseen factors.
Beginning in August, several of the Dams 26 power generators will come on line, each producing over a half a million kilowatts of energy, producing 5.5 billion kilowatts of energy by the close of the year. By 2009, the Dam will generate over 80 billion kilowatts of energy annually. The Three Gorges Project will also allow the passage of 10,000-ton freight ships to navigate through the Dams canal locks.
In addition one of primary goals of the project, touted as the worlds largest water conservation facility, is to have Three Gorges Dam act as a reservoir during Chinas flood season. When the dammed waters reach the intermediary level of 440 feet above sea level, the reservoir will store over 70 billion cubic feet of floodwater. By the end of the project, the reservoir capacity will increase ten-fold. However, this increased capacity will do nothing to deter flooding that has routinely occurred downstream of the Dam.
Questions now remain about the Dams impact on pollutants that normally flowed from the Yangtze into the East China Sea. The backup of pollutantsrunoff of industrial and agricultural activitiesalong with E.coli pollution from human waste, may cause the reservoir to become undrinkable. The reservoir may also suffer a loss of wildlife due to the build up of silt levels during the Dams operation. Chen Yiyu, the vice-president of the Chinese Academy of Sciences has said protection measures for both animal and plants will be in place by 2010.
As President Jiang Zemin cautioned six years earlier:
In short, we should take into consideration the overall situation and a long-term perspective, formulate plans on a scientific basis and adopt practical and effective measures to achieve a coordinated economic, social and ecological development.
However, less than two weeks since its official operation, the Three Gorges Dam already has shown 80 hairline cracks in its surface. Head of the inspection committee, Pan Jiazhong, stated that though the cracks do not pose a threat to safety, leaking could occur if they are not promptly repaired.
