The ordinary operation figure for perennial regulation reservoir with many objects has many shortcomings such as random runoff, overlapping operation areas and so on. This paper establishes a multi-levels operation figure for the Jinxiuchuan reservoir in Jinan city to meet the different water users. Using chronological method a series of arid year is selected to calculate the water supply limited line and control failure line which respectively concerns the part of and all of water supply demands, and then the comprehensive failure control line which take enhanced power generation into account. A serial of annual runoff is used to validate this multi-levels figure and the results show that compared to the ordinary way the guarantee rate of irrigation rises from 75% to 77%, municipal supply from 74% to 90%, and generation from 90% to 91%, which indicate that this study can optimize the operation of this kind of reservoir.
