Dukan Lake is a key source of drinking water for the residents of Sulaimani city in the Kurdistan Region of Iraq. Recently, concerns regarding its water quality have grown; however, there has been limited research on the lake’s condition. Therefore, this study was undertaken to evaluate the water quality of Dukan Lake using the Water Quality Index (WQI). Water samples were collected from three locations in the lake during 2022and 2023. Nine water quality parameters, namely, dissolved oxygen, biochemical oxygen demand, pH, turbidity, electrical conductivity, hardness, alkalinity, sodium, and nitrate were analyzed in the samples. It was noted that all water quality parameters, except for alkalinity and hardness, were within the permissible limits. The average WQI value was calculated to be 63, with a range between 56 and 69. All water samples fell within the “Good water” category. It is concluded that the water from Dukan Lake is safe for drinking. However, ongoing monitoring of water quality is recommended.
