This researchwas carriedout by predicting potentialwater resources useWatershedModeling System, calculate cropwater requirements todetermine the surplus-deficit water. The results were obtained monthly discharge based predictionWMS 1,32-24,7 m3/sec, which the lowest discharge in September and the highest in February. Crop water requirements,shortage ofwaterf or 7months (May-November). Utilization of the damme driverwater at the weir Pamukkulucan supply these needs, with a surplus of water, 0,1-3,85m3/sec/month
