One of the most important problems in water resources management is the optimum exploitation of dams reservoirs. This task has been accomplished by various ways. Application of the heuristic algorithms has been noticed because of the old methods are difficult and expensive. One of the most important algorithm is the ant colony algorithm. In this study to resolve the problem of optimum exploitation of reservoir system of the Alavian dam, located in the Soofi Chay basin in Maragheh, acquired data of 21 years were used. The current study shows that the spillway out flow occurs when the reservoir in flow is more and the irrigation demand has been supplied. Noting that the reservoir inputs were discrete the model was forced to select the discontinuous data leading to optimum values being different from the irrigation demand and spill or storage of water in the reservoir occurred. The rate of this situation is reduceable by decreasing the discretization intervals.
