On this study, an operation of Bening Reservoir has been observed. The observation was directly done on the Bening reservoir location, which is located in Lamongan, East Java, Indonesia. As the Indonesian Government decided that water resources development in Indonesia is one program to target the supply water needs, where water resources development used for irrigation is an important aspect. One of other advantages on the use of water as irrigation is the electric power hydro generation. There is a need for a water optimization capacity and reservoir operation system for the anticipation of surface water resources water restriction and a higher cost of hydraulic structures to intensify the need for an optimum capacity and an effective operation for reservoir systems. It is a must that allocating the water use as efficient and effective as possible. An optimization system model was then erected on this study. As mentioned above that the case study for this observation selected was the Bening reservoir in Lamongan. The optimization analysis result would give a lot of information for the water allocation for every objective function. The Basic Irrigation Allocation Optimization is based on the yearly reservoir data. The reservoir yearly data is the reservoir data which could reserve water during the rainy season and could support the activities on the dry season. On this type of reservoir, that should be understood, is that the water reservoir inflow quantity has a different water outflow quantity. The methodology used in this study is concentrating on the water irrigation allocation optimization. The result of this optimization could be used as the rule curved pattern to design the basic of reservoir operation. The rule curve considered the irrigation outflow water optimization discharge, the head and the hydro electrical power energy prediction. © Research India Publications.
