 This study was aimed to determine national sanitation foundation water quality index (NSFWQI), sodium adsorption ratio (SAR) and some other parameters such as electricity conductivity (EC) and sodium percent (%Na) to investigate the quality of the Jajrood and the Damavand rivers, the mix of them and Mamloo dam. 

 The tested parameters were pH, dissolved oxygen, biochemical oxygen demand, total solids, nitrate, phosphate, turbidity, temperature, fecal coliform, EC, Na, potassium (K), calcium and magnesium. The used indices were NSFWQI, SAR, %Na and magnesium hazard. 

 average WQI for the Jajrood river (S1), Damavand river (S2), mix of S1 and S2(S3) and the Mamloo dam (S4) were 71.7 (good), 64.5 (medium), 70.6 (medium) and 77.3 (good), respectively. According to USA Laboratory Diagram and Wilcox diagram, all the sampling points were in C3-S1(very good to good classes), C2-S1(good to permissible classes) categories. 

 According to the results, the water of sampling points is unsuitable for direct human consumption. However, for the S1, S2 and S3 as drinking water, advanced treatment may be needed. For S4 as a drinking water source, conventional treatment may be necessary. All the sampling points are suitable for irrigation purposes under normal conditions.
