This enormous endeavor has displaced more than 1.3 million people, swallowed about 1,500 municipalities, and has created a reservoir more than 373 miles long.
The project is seen as an important future source of energy for China’s growing electrical consumption and is expected to produce 100 billion kilowatt-hours of electricity a year when it reaches capacity.
But some environmentalists are worried that the silt buildup behind the dam could pose navigation problems and that the huge reservoir could result in seismic activity. They are also concerned that there may be accumulations of toxic materials and other potential pollutants from inundated industrial sites.
Three Gorges Dam plan, which cost $37.24 billion, was controversial some time before being implemented in 1994.
