The Three Gorges Dam is a hydroelectric river dam which spans the Yangtze River in Sandouping, Yichang, Hubei, China. As of 2007, it is the largest hydroelectric river dam in the world.
The dam wall is made of concrete and is about 2,335 metres (7,661 ft) long, and 185 metres (607 ft) high. The wall is 115 metres (377.3 ft) wide on the bottom and 40 metres (131.2 ft) wide on top. The project used 28,000,000 m³ (36,600,000 cu yd) of concrete, 463,000 tons[vague] of steel, and moved about 134,000,000 m³ (175,000,000 cu yd) of earth. The reservoir is over 600 kilometres (373 mi) long and can hold 39.3 cu km (9.43 cu mi) of water. The project will flood 632 square kilometers (395 square miles) of land to create a reservoir about 644 kilometers (400 miles) long by 112 kilometers (70 miles) wide. The total electric generating capacity will reach 22,500 MW and claims the title to being the largest hydro-electric power station in the world by capacity when it is completed. Several generators still have to be installed, and the dam is not expected to become fully operational until about 2011.
