Water surface storage capacity of Foziling Hydropower Station

The reservoir water surface is sandwiched between rolling mountains on both sides. The main river channel of the basin is 77 kilometers long. When the normal water storage level is 124.96 meters, the storage capacity is 384 million cubic meters and the flood detention capacity is 251 million cubic meters. The Xingli storage capacity is 271 million cubic meters, the dead storage capacity is 125 million cubic meters, the verified flood level is 130 meters, the maximum restricted water level in the flood season is 114 meters, and the historical highest water level is 130.64 meters. The normal water storage level of the reservoir is 124.96 meters. The water surface area is 20.15 square kilometers. The water from the reservoir is mainly supplied by rainfall. The water quality is good, basically pollution-free, and the water quality is Class II.

The sediment content in the incoming reservoir water is concentrated during the flood period, and the sediment content is very small during the dry season. According to measurements: 13 million cubic meters of sediment entered the reservoir before 1969, with an annual average of 1 million cubic meters per square kilometer. A loss of 7.9 million cubic meters. In 1979, it was measured that 40 million cubic meters of sediment entered the reservoir. In the next 10 years, the annual average was 2.7 million cubic meters, with a loss of 2,126 cubic meters per square kilometer. In 2002, preliminary measurements were taken during the risk removal and reinforcement work, and it was found that cubic meters of sediment had accumulated. 2.1 Immigration to the reservoir area

Before the reservoir area was flooded, there were many valleys and plains, with fertile land and rich products. The submerged market towns such as Guanjiadu, Mozitan, Longjingchong, Broom River, Caochang River, Wuqi River, and Meijiadu were all once water and land transportation hubs and important commodity distribution centers in mountainous areas. After the reservoir was built and stored, the submerged area reached 23.84 square kilometers (10,000 tons), 6,048 houses were demolished, and 9,148 villagers were relocated. Most of them migrated to nearby areas, so the population around the reservoir increased, the cultivated land decreased, the resources were depleted, and the immigrants' life became difficult. In order to solve this problem, the local government made readjustments, moved some people out, and provided certain living subsidies, which solved the remaining problems of resettlement.
