Gangnan Reservoir and Huangbizhuang Reservoir under combined operation often can not reach normal pooling level in past years. This problem is discussed in this paper, and the possibility to raise the limit flood water level of Gangnan Reservoir is given on basis of comparing the additional inundation loss and the marginal benefits. This research is important to North China where water resources are very deficient.
