Located in Yichang City of Hubei Province, 38 km away from the Three Gorges Project, the Gezhouba Water Conservancy Project is stared in 1970 and finished in 1988. Until the Three Gorges Project finished, Gezhou Dam will remain as the biggest water conservation project along the Yangtze River.

When the Yangtze River goes through the Nanjin Pass, the river suddenly becomes a lot broader, widening from 300 meters (0.2 miles) to 2,200 meters (1.4 miles). 2,606 meters (1.6 miles) long and 53 meters (173 feet) high, the dam divided the Yangtze River into three parts, Da Jiang, Er Jiang and San Jiang in a south to north order.

The process of passing the dam itself is an interesting experience. Since the water level on one side of the dam is 30m higher than that on the other side, the boat has to ascend to the other side of the dam to continue its voyage.
