The study was carried out in the Polish Lowlands in the summer periods of 2005-2008. The results from almost half of the sites were very similar and showed that rivers were of moderate quality. Chlorophyta, Cryptophyta and Euglenophyta were common at sites with higher concentrations of phosphorus and nitrates, the presence of modifications, silty river bottom and higher pH. Nuphar lutea or Cladophora agg. were dominant species in the group of macrophytes and macroscopic algae. Diatoms occurred in significantly higher densities at sites with lower concentrations of nutrients, no or minor modifications, sandy river bottom and higher water conductivity, where Elodea canadensis, Glyceria maxima and Sparganium emersum were dominant macrophyte species.
