The Three Gorges Dam( 三峡大坝 ) the largest dam in the world is also the largest engineering project on the surface of the earth. It aims to make the mother of all floods the Yangtze River into a tame river make electricity and power much of eastern and central China with his 18 200 megawatts( 兆瓦 ) electricity. It will create a huge deep water lake and make it possible for 10 000 ton ocean going ships to sail 1 500 miles inland from the Pacific to the city of Chongqing with its 15 million people making it the world’s largest seaport. Construction has already started. The dam will be about 6 860 feet wide and 611 feet high at a spot called Sandouping near Yichang.

It is obvious that such a grand project will do a great deal of good. The most important is flood control. By building a dam instead of new coal plants to meet its growing demand for electricity. China will give off much less poisonous gases into the air.

However some scientists don’t agree to the project. They say that Chongqing and dozens of other cities along the river will put much waste into the reservoir( 水库 ) which can do harm to people fish and other living things that depend on the river. Sedimentation( 沉积 ) the damage of a breach( 决口 ) are problems too.

The Three Gorges Dam could be considered when it is finished in 2009 a new eighth wonder of the world as to size alone.
