Main tributaries of Bama County:

General situation of water conservancy

The middle and upper reaches of the river meander between Chongshan gorge, with many rapids and abundant water energy. The theoretical reserve of water energy is 88000 kW. Three hydropower stations have been built in Bama County, with an installed capacity of 7120 kW (the installed capacity of Cifu hydropower station is 2400 kW, which was abandoned in 1992 due to the submergence of Yantan Hydropower Station), 41 electric irrigation stations and water turbine pumping stations
