Selection Of The Site
Sandouping, 7 km from the entrance of Xiling Gorge at the lower reaches of the Yangtze River, was selected as the site of the Three Gorges Dam in 1959. The river here is much bigger than it is in other area. There is a small island named Zhongbaodao in the middle of this part of the river. It is the best choice of the site for the dam.
The 1st Phase Of The Construction: 1993 - Nov.1997
The planning of the project was started in 1993. The actual building of the Dam started on 14 Dec. 1994. ZhongbaoIsland was used to build dyke A to dam the river water and to connect the right bank with the other dyke. In order to build the main part of the Dam and the diversion channel afterwards, foundation work B and foundation work C which is long and thin were built in the dry riverbed. At the same time, channel construction such as Lock D started.
The 2nd Phase Of The Construction: Nov. 1997 - 2003
Dyke A was built and the left bank was connected to another dyke. Later, the flood-relief dam and the main part of the Dam B for the installation of generators were built in the dry riverbed and then, 14 generators were installed. Diversion Channel C was opened to navigation and it was dammed again in Nov. 2002.
The 3rd Phase Of The Construction: 2003-2009
Diversion channel is dammed. Dyke A is being built and the right bank with the other dyke will be connected again.
