Data on the composition of the flora of cyanobacteria and algae Vtoraya Rechka River were obtained; it is represented by 88 species (92 species, varieties, and forms) from six divisions: Cyanobacteria, Bacillariophyta, Chlorophyta, Charophyta, Rhodophyta, and Euglenozoa. Twelve species were classified as dominants and subdominants: Navicula lanceolata, Nitzschia palea, N. inconspicua, Nitzschia sp., Diatoma vulgare, Encyonema silesiacum, Gomphonema angustatum, Rhoicosphenia abbreviata, Ulnaria ulna, Craticula subminuscula, Sellaphora obesa, Phormidium uncinatum. The assessment of the water quality of the Vtoraya Rechka River using the Pantle-Buck’s method. It was found that the river waters belong to the oligo- and betamezosaprobic zones and correspond to the II–III class of water quality. Clarification of species identification of one of the main dominants, correction of individual indices of saprobity (s) of dominant species will be performed to correct the obtained data on Vtoraya Rechka River water quality.
