Baisha Reservoir is located in the upper reaches of the Shaying River in the Huaihe River Basin. The dam site is located 300 meters north of Baisha Village, where Yuzhou City and Dengfeng City, Henan Province, are located. Baisha Reservoir is one of the large-scale reservoirs built in Henan Province in early Huaihe River in the early 1950s. It is a provincial-level large-scale reservoir under the control of flood control and irrigation, industrial water supply, aquaculture and tourism. Reservoir dam buildings have a main dam and east and west, deputy dam, water spillway and water diversion tunnel construction. The original sluice flood gate is located on strong weathered quartz sandstone with developed fissures and obvious bedding. The rock mass is moderate to strong water permeable, with poor engineering geological conditions, such as gate base leakage and uneven subsidence. Provincial Planning Commission in
