Facts


The 16-year project is due to be completed in 2009. The river's level is expected to rise to 175 metres. By mid-June 2003 the dam was holding back 12 billion cubic metres of water. The dam's storage capacity is nearly 40 billion cubic metres. It will create a 658-sq.-km reservoir. Its concrete wall is 192 metres high. It has a total of 22 sluice gates. It will have 26 700-megawatt turbine generators. They are expected to produce 18.2 million kilowatts by 2009. Eleven of the reactors were in place as of January 2005. It has the world's largest lock system, 6?kilometres in length. The lock lifts and lowers ships in five stages. The dam is located in Yichang, in the central province of Hubei. It's China's biggest engineering project since the Great Wall was built more than 2,000 years ago. Total projected cost: 180 billion yuan ($26.5 billion).

Cons and Pros of the Three Gorges Project
Introduction



China's massive Three Gorges hydroelectric project has generated plenty of controversy from the start. It was first proposed in 1919 by revolutionary leader Sun Yat-sen as a way of providing energy to fuel the nation's industrial development. The plan was revived in 1954 as a way to control the chronic overflow of the legendary Yangtze river after tens of thousands were killed in widespread flooding. After several false starts, work began in earnest in 1979. Advocates say China's development depends on it. They say it will provide a clean source of energy for future generations. But critics say it could be a monumental ecological disaster. The dam's sluice gates were closed on June 1, 2003, allowing the reservoir behind it to begin filling. By June 10, 2003, the water was 135 metres deep, and it's expected to be 175 metres deep by 2009.
