The article presents the results of the analysis of the systematic structure of the algae flora of the studied reservoirs of the Orenburg region. The revealed richness of flora includes 104 species and varieties belonging to 7 divisions, 12 classes, 23 orders, 32 families, 58 genera. The dominant divisions are Chlorophyta, Bacillariophyta and Cyanophyta. The total number of microalgae at the study points was dependent on the anthropogenic load on the reservoir. Certain indices of saprobity of reservoirs indicate the presence of dissolved organic matter in the bulk of the studied reservoirs and pollution of natural waters.
