Buyuk Menderes River basin is one of the most important agricultural basins in Turkey, and Buyuk Menderes River and its tributaries have long been considered as receiving water body for disposal of industrial and municipal wastewaters. Due to rapid urban and industrial development in the basin after 1980's, the status and decline of water quality of Buyuk Menderes River have become an important public concern. In this study it was aimed to investigate the spatial variability of total dissolved solids (TDS), chloride (Cl), sulphate (SO(4)), sodium (Na), potassium (K), calcium (Ca), magnesium (Mg) and chemical oxygen demand (COD) along Buyuk Menderes River with special emphasis on the effect of the tributary Curuksu Creek on the water quality of Buyuk Menderes River using long-term water quality monitoring data recorded at nine sites from 1995 to 2006. The results showed that the water quality of Buyuk Menderes River deteriorates dramatically after the confluence of Curuksu Creek with Buyuk Menderes River. When mean values of constituent concentrations considered, percent increases in TDS, Cl, SO(4), Na, K, Ca, Mg and COD after the confluence were calculated as 104.8, 156.1, 334.7, 148.2, 39.0, 85.6, 140.9 and 170.8, respectively. Based on these results, basin management action plans in Buyuk Menderes River basin should focus primarily on the improvement of water quality of Curuksu Creek, which necessitates the construction and proper operation of wastewater treatment plants for industrial and municipal communities around Denizli and Saraykoy.
