Water quality impact assessment of the river Ibar hydropower cascade project is analyzed in this paper, as one of possible aspects of environmental impact assessment. Based on available data provided by authorized institutions, the current state of River Ibar ecological and chemical status is determined in accordance with the methodology prescribed by legislation. The ecological status of the water course between Raska and Kraljevo is rated as moderate, with evaluation considered as reliable. At the same time, the chemical status is rated as good. Quantitative assessment of possible impacts on water quality is conducted by dual approach: 1) application of hydrodynamic model, utilized for analysis of possible thermal regimes in cascade reservoirs, and 2) application of the „method of analogy“ to the existing, well studied reservoir „Celije“, the reservoir with similar morphological characteristics and water quality conditions at the entrance of the system.Results indicate that future cascade reservoir system will represent a number of aquatic ecosystems that will perform as a transitional form between river and lake systems. From the environmental perspective, it is important that thermal stratification of reservoirs during the warm seasons is not expected to be established. Consequently, the eutrophic potential of the river Ibar, based on significant content of macroelements in water, is not expected to be fully realized.
