Flood control and water use regulation by dam operation play important roles in total management of a large-scale river basin. A new method of discharge control intended to increase the efficiency of flood control and water use is proposed in this paper. This method is based on the idea that there is no risk to reduce reservoir level if the amount of anticipatory release equal to the amount of inflow which flows into a dam certainly from the rainfall that has already fallen. With this method, it is possible to achieve higher storage level in reservoirs even during the flooding season, providing more opportunities for water use in addition to flood control. Furthermore, large amount of water is discharged from time to time as the anticipatory release which is useful to maintain river environment.
