1 Project Overview Banqiao Reservoir is located in the upper reaches of the Ru River tributary of the Huaihe River, 45 km west of Zhumadian Banqiao Town, Biyang County. Construction started in March 1951, completed in 1952 and expanded in 1956. It is one of the earliest large-scale reservoir projects newly built in New China. Reservoir control basin area of 762km ~ 2, once in 100 years, the design water level of 114.76m, storage capacity of 418 million m ~ 3; in 1000 once the check water level 116.14m, storage capacity of 492 million m ~ 3. The dam type is a clay core wall sand dam with a crest width of 6m, a maximum dam height of 24.5m, a dam length of 2020m, a crest elevation of 116.34m and a crest elevation of 117.64m.
