Reservoirs are built for various purposes such as storage water during the rainy season. The water fluctuation of the reservoir is strongly influenced by the climate indicating the inflow and outflow of the reservoir. The reservoir inflow is incoming water in the form of river and rain stream, while outflow reservoir is evaporation, seepage and water irrigation requirement. El-Nino is an event of low intensity of rain below the average and occurs over a long period of time. The current El-Nino is can only identified from the high evaporation and the low depth of rain, making it very difficult to predict the occurrence of EL-Nino. The reservoir storage has a measurable volume that can be used to predict the occurrence of El-Nino events very easily and very accurately. This study aims to identify the characteristics of El-Nino based on the volumetric changes of reservoirs in the ZOM region from the reservoir site. Semi-monthly data in the year of El-Nino occur are used in this investigation. The results showed that strong, moderate and weak El-Nino indicated by decreasing reservoirs volumetric of ≥50 %, 30-50%, and ≤ 30%, respectively.
