Material & Methods: This study is a descriptive cross sectional one the sampling occurred in 12 months of 2014 in seven different stations. Quality parameters that were measured include: pH, TS, BOD, DO, nitrate, phosphate, temperature, turbidity and fecal coliforms. Data were analyzed by NSFWQI.
Results: According to NSFWQI index, in the studied stations during the year, the highest quality was observed in station No.4 with the score of 69 and the lowest quality in station No.1 with the score of 65.
