Lakes and reservoirs, except groundwater and surface water, are in use for water supplying. In most cases, the reservoir was considered as a physical object from the hydroconstrucional and hydrogeological aspects and the ecological and biological aspects was ignored. Reservoirs are objects that were created by anthropogenic activities in the basin. They have their own singularity and their developmental stages. In the last-the evolution phase reservoir is affected by eutrophication, whose intensity depends on the amount of nutrients from the basin. Natural and anthropogenic influences give them more characteristic of unstable aquatic systems, dominated by the processes of eutrophication. With regard to development of eutrophication in reservoirs with water suppling as the main purpose, becomes actual again after frequent blooms, significant amounts of cyanotoxins and consumer complaints about sensory properties of drinking water. The aim of this study was to identify the causes that le...ad to the degradation of the water quality in the reservoir, and the factors that they have a long term effect on its trophicity. The establishment of sanitary protection zones are the key factors for the maintenance of water quality in reservoirs.
