Here, after rushing out of Nanjin Pass ("South Ford Pass"), the Yangtze River slows down and widens from 300 m (980 ft) to about 2,200 m (7,200 ft) at the dam site. Two small islands, Gezhouba and Xiba, divided the river into three channels. There the Gezhouba Project was built.
The Gezhouba Hydroelectric Power Plant generating capacity of 3.11 GW along with three ship locks, two power stations that generate 14,100 GWh of electricity annually, the 27 gates of the spillway, and the no flowing Dam on both banks. The dam is 2,595 m (8,514 ft) long with a maximum height of 47 m (154 ft). The reservoir has a total volume of 1,580 m3 (55,797 cu ft).
The navigation lock No.2 on the third channel was, when built, among the 100 largest in the world. The lock chamber is 280 m (920 ft) long and 34 m (112 ft) wide, with a minimum draft of 5 m (16 ft) at the sill. It provides passage for 10000 ton ships.
