Nanxi Reservoir started construction in August 1974 and was completed in December 1983. The reservoir is located in the middle reaches of Nanxi, a tributary of the Beixi River, 18 km away from Fuding Chengguan, with a catchment area of 164 km 2 above the dam site, with a total storage capacity of 680072 cubic meters and a storage capacity of 50.1 million cubic meters below the normal high water level. With a capacity of 46.45 million cubic meters, the average annual runoff in the reservoir area is 1.36 meters with an average runoff of 223 million cubic meters. It is a comprehensive medium-sized reservoir integrating flood control, urban water supply, power generation and irrigation. The reservoir hub is dominated by the dam
