Therefore, because Kizilca creek (Karasu) feeding Akkaya reservoir (Nigde, Turkey) is contaminated with high bacterial loadings, and its ecosystem also becomes dysfunctional, it is examined the change in water quality of Kizilca creek and Akkaya reservoir depending on the distance, their water guality parameters was analyzed between October 2014 to September 2015 periods, and determined their quality classes according to Water Pollution Control Regulation. Water samples were collected at monthly intervals from five stations chosen on creek toward downstream from upstream. The values and degrees of flowing rate, temperature, pH, Dissolved Oxygen (DO), and Faecal Coliform (F.Coli.) were determined for each station separately. Data obtained from the experiment results shown that Kicilca creek was in low quality standard (Class III) in terms of F. Coli. according to intra-continental water quality standards declared in water pollution law. As a results of studies, it was determined that creek was excessively polluted and a most significant threat to Akkaya reservoir.trinfo:eu-repo/semantics/closedAccessIn-stream pollutionlake pollutioncontrol of drinking water sourcesnatural wastewater treatment systemsArticle1412837WOS:000453165300004N/A
