The importance of preservation and improvement of the quality of surface waters implies the consideration of the current ecological state of water quality. The aim of this paper is to present the two methodologies used for determination of the ecological status of the Ibar River. The analysis of measured concentrations of selected physical and chemical parameters, which are the indicators of water quality, is based on the data obtained from the stations along the river. Ecological classification of watercourse is defined in accordance with the methodology prescribed by Regulation on the parameters of the ecological and chemical status of surface water and the parameters of the chemical and quantitative status of groundwater. The research data were obtained from the Serbian Environmental Protection Agency from 2013. It was found that some parameters exceeded the limit values of required good status, and therefore, the Ibar is given moderate ecological status. Moderate ecological status of the river Ibar corresponds to Class III watercourses. The conditions that correspond to biological parameters are typical for a given status. The ecosystem approach clearly indicates the need to take continuous monitoring in order to prevent disruption and to improve water quality as an integral part of the environment protection.
