Water Quality Assessment of Karaidemir Dam Lake (Tekirdağ, Turkey): In terms of Agricultural Irrigation and Drinking Water Supply

Tekirdağ Province is located in the Thrace part of Marmara Region and the region can be declared as an agriculture and industry city. Karaidemir Dam Lake, which is being used for agricultural irrigation and drinking water supply and flood protection, is located in the Tekirdağ Province of Turkey. In this study, water quality of Karaidemir Dam Lake was evaluated in terms of agricultural irrigation and drinking water supply. For this purpose, water samples were collected from 3 stations selected on the reservoir in spring season of 2018 and total of 16 physical, chemical and biological water quality parameters were measured. According to detected data, Karaidemir Dam Lake has moderate salty water (C2) in terms of total concentration of soluble salts and the water of reservoir can be used for irrigation except stenohaline plants. Karaidemir Dam Lake has I. – II. Class water quality in terms of temperature, dissolved oxygen, oxygen saturation, pH, TDS, nitrate, sulphate, fluorine, EC and phosphate parameters; and III. – IV. Class water quality in terms of BOD, FC and nitrite parameters in general. It was also determined that any investigated parameters except turbidity have not exceeded the drinking water limits.
