From 2111 to 2111, the hydrology of Chenghai was very complicated. According to the data of hydrological observation station, the average precipitation from 1961 to 1981 was 725.5 mm, while the average evaporation from 1967 to 1974 was 2269.4 mm. From 1961 to 1972, the water level dropped by 1.73 meters, with an average annual drop of 1.14 meters; Through reduction calculation, the average annual income of water is 12 million cubic meters, accounting for 92.7% of the total loss, and the annual water shortage is 24 million cubic meters. According to the disparity between evaporation and precipitation, the water level will drop by 1.73m in 2112. If there is no other water supply, the status quo cannot be maintained. Nanjing Institute of Geography, China Academy of Sciences observed the bottom topography of Chenghai Lake in Yongsheng in May, 1981, and came to the conclusion that Chenghai Lake can basically maintain a balanced state for many years, mainly relying on groundwater recharge in the east and west mountains; According to the year of Yongsheng County Records, there are three sources of water in Chenghai: first, there are underground springs in the northeast of Chenghai, which originate from the lake and are the main sources; Second, the old record: the dam tube river flows into Chenghai from the Jiming Mountain side of Qingquan Township; 3. On the water surface, there are Liujia River, Pumi River, Tuanshan River and Jiguan River in the east of the lake; West Lake Second Construction Pass, Jinzaolang Camp; Heiwu, Hubei.
