The paper presents the results of a study of the water quality in the Vrutci reservoir on the river Djetinja in the Užice region. A long-term monitoring of the surface water of the river Đetinja upstream from the city of Užice has shown that the water in the profile of the village Vrutci has been extremely clean at different times of the year. Due to 30-year long human activities on the lake water and in the coastal area the water can no longer be safely used for basic water supply needs of the population. The analysis of the quality of the water in the reservoir and the analysis of phytoplankton revealed the presence of 65 taxa and 7 blue-green algae (Cyanobacteria, Chrysophyta, Bacillariophyta, Dinophyta, Cryptophyta, Euglenophyta and Chlorophyta). The communities of phytoplanktons at the sites near the dam and in the middle part of the reservoir are dominated by Cryptophyta and Bacillariophyta species and the entrance to the reservoir is exclusively dominated by Bacillariophyta species. Plagioselmis nannoplanctica (syn. Rhodomonas minuta) Skuja is the most abundant species of Cryptophyta and Cyclotella ocellata Pantocsek of Bacillariophyta genus. The dominant species in the lake water is the cyanobacteria Planktothrix rubescens, whose presence on a number of profiles in the Vrutci lake water storage exceeds 95%.
