One of the basis of planning to exploit the country's water resources, is determine the water potentials of the country and assessment the quality of water content. Babaheydar dam is one the most important dam in country which is located in Chaharmahal bakhtiari province and has important role in supplying drinkable water for Farsan county. In this regard, the present study aimed to evaluate the dam water quality by using NFSWQI index. In this index 9 chemical and physical parameters used in order to determine water quality. Therefore seven stations for sampling determined and during 2012-13 samples collected and at last by using GIS software, dam condition in according to that index had analyzed. The results show that water of dam overall by earning  points within 71-90, set in moderate class and among all stations, station 6 has best condition because only zero coliform was found in this station. In this study, the most important factor which is affected water quality was decreasing the water discharge of dam that means By reducing water rights downstream of the dam, the water discharge  is reduced and thus the water quality has also declined.
