        Optimal operation of local resources can be effected in conservation water resources of paddy fields and corrected water distribution. Therefore, in this study, a simulation-optimization model of exploit ponds has been developed for investigate the role of ponds to store local water and use it to supply irrigation water requirement of paddy fields. Evapotranspiration, irrigation water requirement, irrigation interval and pond balance were simulated and then number of canal intake, storage volume and released volume of pond were optimized by binary genetic algorithm. The developed model was applied for Fashtam pond in Sangar, Gilan province. The result showed that in normal year 54% of irrigation requirement of paddy fields were supplied by rainfall and runoff water saved in Fashtam pond and the rate of over flow water of pond to maximum volume of that were74%. The model result for scenario of increasing pond storage two times showed the rate of pond in supplying irrigation requirement of paddy fields is increased to 91% Manuscript profile
