Acta Aquatica Turcica, 16(3), 305- 312. https://doi.org/10.22392/actaquatr.626918 Abstract Murat River is the most important tributary of the Euphrates River, which has the highest water potential in Turkey. The seasonal variation of water quality parameters and water quality status of Murat River were determined according to the “Regulation on Surface Water Quality Management” criteria. 19 different parameters were measured in water samples taken from four different stations during the research. These parameters were temperature, pH, dissolved oxygen, electrical conductivity,
