Built in 1994 and completed in 2009, the Three Gorges Dam
is the largest water conservancy project ever undertaken by man. The
Three Gorges Dam is located near Sandouping, which is in the middle of
the Xiling Gorge, the longest of the Three Gorges.
The
Three Gorges Dam is 2,335m long, 185m high, 18m wide on the top and
130m wide at the bottom. The dam has raised the river to a level of 175
meters above sea level, creating a 600 kilometers long reservoir with
storage capacity of 39.9 billion cubic meters extending from the dam
site all the way to Chongqing. 570,000 acres of farmland, villages, and
cities in 19 counties have been flooded, causing 1.5 million people to
be relocated.
The estimate for construction of the project is 26
billion US dollars. The building of this huge dam was for the purpose of
flood control, electricity, navigation, and irrigation.
History of the Three Gorges Dam
The idea for the Three Gorges Dam was first proposed by Dr. Sun
Yat-Sen, the pioneer of the Republic of China, in 1919. In his article,
entitled "A Plan to Development Industry", Sun Yat-Sen mentions the
possibility of damming the Yangtze River to help control floods and
generate electricity.
In 1944, an American dam expert named J.L.
Savage was invited to do field research on possible locations for the
project. Two years later, the Republic of China signed a contract with
the U.S. Bureau of Reclamation to design the dam. More than 50 Chinese
technicians were then sent to the United States to study and participate
in the creation process. However, the project was shortly abandoned due
to the Chinese civil war that followed World War II.
Talks of the
Three Gorges Dam resurfaced in 1953 due to continuous floods that
occurred on the Yangtze that year, killing over 30,000 people. One year
later, the planning phase began once more, this time under the
collaboration of Soviet experts. After two years of political debates
over the size of the dam, the project was finally approved by the
Communist Party. Unfortunately, plans for the construction were once
again interrupted, this time by the disastrous political campaigns of
the "Great Leap Forward" and the "Proletarian Cultural Revolution".
The
market reforms introduced by Deng Xiaoping in 1979 emphasized the
necessity to produce more electricity for economic growth. With approval
from the new leader, the location of the Three Gorges Dam was then
officially determined, to be located at Sandouping, a town in the Yiling
District of the Yichang prefecture, in the province of Hubei. Finally,
on December 14, 1994, 75-years since inception, the construction of the
Three Gorges Dam finally began.
Four goals for the Three Gorges Dam Project
1. Flood Control
The history of the Yangtze River includes many devastating floods over
the centuries killing thousands of people and causing millions of
dollars in damages. The dam will reduce the impacts of flooding since it
will have a flood control capacity of 22.15 billion cubic meters.
2. Power Generation
The use of hydroelectric turbine generators will reduce China's
dependency on coal, a hydro carbon that produces greenhouse gases. The
Three Gorges Dam will produce about 84.6 billion kilowatt hours of clean
energy annually.
3. Navigation
The presence of the dam, the
reservoir, and the ship locks will allow large ships to travel up and
downstream for the first time. Ships from Chongqing will be able to
transport goods all the way to the sea at Shanghai.
4. Tourism
Since the Three Gorges Dam Project is the largest hydroelectric dam in
the world, it is expected to be popular among tourists visiting China.
Three gorges dam tour is a must-do for Chongqing package tour.
