Gezhou Ship Lock / Gezhou Dam

Gezhou Ship LockThe Gezhou Dam is located at the lower end of the Three Gorges in the suburbs of Yichang City, Hubei Province, 38
Km from the Three Gorages Dam. This huge modern construction has become one of the important scenic spots in
Yichang and over ten thousand of visitors come to visit each year. It is the first dam on the Yangtze River and the
largest hydroelectric project in China.

The dam is 2.3 kilometers from Nanjin pass in Xiling Gorge narrows. After passing through Nanjin, the surface of the
Yangtze River is suddenly enlightened, with the surface of the river widened to over 2200 meters from original 300
meters suddenly. The water of the river has been divided into three streams by Gezhou Dam and Western Dam of the
river, called Big River, the Second River and the Third River from right to left, and only in flood period it discharges. Gezhou Dam hydro-junction project is built here.

The major components of Gezhou Dam are its power stations and its ship locks and sluices for permitting the passage of ships up and down the Yangtze. There are ship locks for the usual variety of tonnage categories, from those for lighter craft to those designed for the passage of heavy ships carrying massive loads.

Gezhou Dam project is mainly made of ship lock, power station, sluice gate, scouring sluice and check dam used for stopping water. The dam is 2595 meters long and its top is 70 meters high and 30 meters in breadth. The project needs to dig out 113 million cubic meters of earth and stone. The total capacity of the big dam is 1580 million cubic meters, which controls dam drainage area of 100 square kilometers.

It has two power stations. One is in the second river and the other in the big river, with 21 generators which produce 2,715 million kilowatt. And its generated energy annually is 14.1 billion degree and it is one of the large hydroelectric stations all over the world. After completion of the Three Gorges Dam, the annual guaranteed output of electricity from the Gezhouba Hydro Power Plant was increased by about 430,000kw.

Gezhou DamWhen crossing the Gezhou Dam by boarding a giant ship, you yourself may experience the wonder created by man with their wisdom and will be delighted to see that in very short time, the giant ship is raised several dozen meters high through the water level readjustment equipment of the dam and with the rise of water level, the giant ship can sail from lower level water into higher level water of the Yangtze River.
