Gezhouba
Water Conservancy Project
 The
Gezhouba Water Conservancy Project includes
the barrage, the power plant, the ship brake,
the flood discharge brake, and the fishway,
etc. It is currently the largest hydropower
station in China.
The embankment is 2,561m long
and 70m high, which controls a drainage
area of 1,000,000km2 with total content
of 1.58 billion steres. The station possesses
of 21 dynamos, with electricenergy production
of 2,715 kilowatts, about 13.8 billion kilowatt-hours
annually.
The project was carried on by
2 stages. The first stage started in 1970,
and now has been completed. The navigation
was kept unobstructed during the stage.
In the second stage the river was blocked
and navigation was stopped so as to ensure
that the dam could be built smoothly.
The Gezhouba Project will be
a conveyance system to the "Three Gorges
Project" in the future. After the Gezhouba
project was finished, the water level of
the river100 km up to the Three Gorges was
elevated 20m, and the sea-route was largely
improved consequently.
The ship lock chamber 3 is 18m
in breadth and 120m in length, which allow
passenger-cargo vessels and civil fleet
less than 3000 tons to pass.
The ship lock chamber
2 is 34 meters wide and 280 meters long
and able to contain ships over 10,000 tons.
It takes about 50 minutes for a ship to
go through it. The second ship lock is one
of the rare giant ship locks in the world.
