In order to increased the amount of water in Sjenica water reservoir (because of higher production of electric energy by hydroelectrical power plant), stagnant waters of Pester field were irrigated to Vapa river and Sjenica lake. Former swamp areas and theirs life communities, represented specific biological filter in Pester high, a kind of natural lagoons, where big amounts of polluted water with nutrients were spent a processed (especially salts of P and N) were characteristic for exact area because of intensive cattle production. After the irrigation on Pester field, raw, polluted water with the large amount of nutrients by Vapa river get to the Sjenica water reservoir where they represented main cause of eutrophication and degradation of water quality in this aquatorium. Heterogenic and numerous algal association in canal of the Pester field is nearly leftover of previous specific algological flora which testifies the presence of species Chaetophora incrassata Hazen (new habitat in Serbia), the first class water indicator.
