In this study, water quality of surface waters of downstream from Tunceli Uzuncayir Dam was determined. The purpose of determining the water quality is to evaluate for what purpose the water mass downstream from the dams can or can not be used. In this context, waters that show “very good” water status, also referred to as high quality waters, are specified as Class-1 waters. These waters include surface waters with high potential for drinking water, water that can be used for recreational purposes, including those that require body contact, such as swimming, water that can be used for trout production, and water that can be used for animal production and farm needs. The waters showing the status of “good water”, which is also referred to as less polluted water, are referred to as Class-2 quality waters. These waters include surface waters with the potential to be drinking water, waters that can be used for recreational purposes, waters that can be used for fish production other than trout, and waters that can be used as irrigation water provided that they meet the irrigation water quality criteria determined by the regulation. In this study, surface water samples were taken in June, July, and August (Summer) in 2019 and the data obtained were compared with the water quality values given in the Surface Water Quality Regulation (SWQR). According to the results of the analysis, pH values were between 7.92-8.01 and the water quality class was determined as Class-1. Temperature values were show changes between 17.2-23.1oC. The electrical conductivity (EC) values took values between 322-384 µS/cm and the water quality class was determined as Class-1. Nitrate nitrogen (NO3--N) concentrations determined between 0.91-1.26 mg/L and according to these results, water quality class was determined as Class-1. Biochemical oxygen demand (BOD5) concentrations were between 2.1-3.5 mg/L while chemical oxygen demand (COD) concentrations ranged between 17.3-25.1 mg/L. As a result, it was determined that surface waters of downstream from Uzunçayır Dam are Class-1 quality in terms of pH, temperature, EC, NO3--N, BOD5 concentrations and Class-2 quality in terms of COD.
