The reconstructed Banqiao Reservoir is designed for 100-year floods and may be subject to maximum flood checking. Reservoir control basin area of 768km ~ 2. The average annual runoff is 280 million m 3, with a total storage capacity of 675 million m 3. The reservoir is mainly flood control, both irrigation and urban supply
