Özet:

This study was carried out in the Kayalıköy reservoir (Kırklareli, Turkey), that is used for agricultural irrigation and aquaculture and to provide drinking and domestic water supply of Edirne province. The study was performed at 3 stations determined in the reservoir during a year from May 2018 to April 2019. The water samples were taken with Ruttner water sample bottles from 15 to 20 cm below the water surface. Water temperature, Secchi disk depth, conductivity, pH, and dissolved oxygen were measured on-site simultaneously with the sampling time. Other physicochemical parameters were analyzed in the laboratory. A total of 43 physicochemical parameters were measured in the Kayalıköy reservoir. Analysis results obtained are compared with Regulation on Modification of Surface Water Quality Management (RSWQM) and Regulation on the Quality and Treatment of Water Provided for Drinking Water (RDWQ). According to the average values of the analysis results the water quality in Kayalıköy reservoir determined generally to be Class I and A1 water. In conclusion, Kayalıköy reservoir has water suitable for drinking, agricultural irrigation, and aquaculture and was classified as having oligomesotrophic character.
