In this study, it was aimed to determine the water quality in the Atasu Dam reservoir basin according to the parameters recommended in national and international standards. In accordance with this purpose, pH, electrical conductivity (EC), total dissolved substance (TDS) and dissolved oxygen (DO) parameters were measured in situ at two-month intervals from the branches feeding the dam lake and the dam lake. Main anions and cations, nutrient parameters (such as nitrate, nitrite), inorganic pollution, bacteriological parameters and trace metals were analyzed in the samples taken from the designated points. It has been determined that the pH value of the waters in the basin is between 6.60 and 8.78 and the EC value is between 42 - 134 mu S/cm. The DO value varies seasonally depending on the water temperature in the side branches. It varies between 8.11-9.36 mg/L in the dam lake. The waters in the basin are in the water class with Ca-HCO3 in terms of main anion cations. Nitrate values vary between 0.7-12.74 mg/L, and nitrite values vary between 0.01-0.07 mg/L. When the analysis results of the samples taken from the side branches and the mainstream in the Atasu Dam reservoir basin were evaluated according to the Water Pollution Control Regulation (2008), it was determined that the waters were of Class I Water Quality in terms of general conditions and oxygenation parameters (DO and COD). According to the NH(4)(+)value, one of the Nutrient Element Parameters, the waters outside the dam lake are class I, and the waters of the dam lake are class II in summer. class is water type. In terms of. NO2-, NO3- and total phosphorus, it is in II. and III. class is water type. It was determined that trace elements were class I in terms of parameters other than Cu and Ni. Trace element concentrations vary between rainy and dry periods. These differences tend to decrease during the rainy season for many elements. Water quality is rated as excellent at every point in the basin, with water quality (WQI) values between 95.45 and 96.56.
