The upstream is about 34.9km away from the proposed Baihe Hub, and the downstream is 179.5 km away from the dam site of Danjiangkou Water Control Hub. This is the eighth cascade recommended in the comprehensive planning report of the main stream of the Han River. The dam site controls a watershed area of 60440km2, with an average annual runoff of 24.5 billion m3. It is a comprehensive utilization project focusing on power generation and taking into account shipping.

Gushan Hydropower Station is mainly composed of discharge structures, power stations, navigation structure and dams on both banks. The dam is a concrete gravity dam with a crest elevation of 188m, a dam length of 640.45m and a maximum dam height of 49.2m The normal water level of the power station reservoir is 177.23m, and the corresponding storage capacity is109000 m3. Four tubular hydrogenerators were installed, with a single unit capacity of 45MW, a total installed capacity of 180MW, and an average annual power generation of 6120,000 kW·h, thus improving the navigation channel in the reservoir area by 34.9km.

The static investment is RMB, and the total construction period is about 4.5 years.
