This paper analyzes the results on water quality in the Medjuvrsje water reservoir (Serbia, Yugoslavia) in the period 1994-1997. The water reservoir was erected for the needs of electric engineering in 1953 as far as 182 km along the Zapadna Morava river stream issuing from the Ovcarsko-Kablarska crag. All the tributaries of the Zapadna Morava flow in torrents, thereby depositing drift onto reservoir and inducing eutrophication process. Water regime in the water reservoir is conditioned by power plant operation, with daily oscillations about 30 cm causing turbulence in aquatic biota, including fish as the most developed aquatic vertebrate by their evolution level and greatest in biomass. Hydrochemical and some hydrobiological parameters influencing productivity of the water reservoir, were assessed. From hydrochemical aspect, this water reservoir contained water, the quality of which was found to be within 2nd-3rd class. The water was, however, loaded with high concentration of NH3, Fe, BPK5 and suspended substances inducing its quality to be out of the class range.
