The rule curve is principal topic in the water resource management. It’s purpose that is remind the time of the restrictions of water supply, stabilize water supply, resuce the impact of water shortage and the opportunity of empty reservior. But if the position of rule curve is too high to subjoin the unnecessary restrictions of water supply. If the position of rule curve is too low to accelerate the reduction of storage and make the shortage be centralized. So we need to fine the better position of rule curve for the minimize impact of water shortage. 　　This research modified the optimal storage trajectories of reservoir. And manufacture the candidate rule curve by two methods: 1.Original optimal storage trajectories, 2.Sorting the water level of reservoir in every ten-day, and let each water level had the probability by weibull formulation and count the curve in particular probability by using interpolation. Finally, we combined the candidate rule curve in each method and simulated by WRASIM-E to find the rule curve in best effect. 　　The case study is rule curve of the Feitsui reservoir.First,we optimize the optimal storage trajectories in different condition of water demand.And the optimal storage trajectories transform to candidate rule curve according to above description. There was no combination of candidate rule curve in Original optimal storage trajectories.Another, we can get rule curve of the minimize impact of water shortage by using the sorting and interpolative candidate rule curve of different water demand.
