RÉSUMÉ

On the whole, 108 species (121 infraspecific taxa, including those containing nomenclatural types of species) of plankton algae of 7 divisions were found in the cascade of ponds. Euglenophyta, Chlorophyta, and Bacillariophyta were represented by the largest number of species. Phytoplankton of the studied water bodies was not diverse in its species composition. It was characterized by a predominance of Euglenophyta and Chlorophyta. In terms of the saprobiological characteristics of indicator species, the studied water bodies belong to the class "slightly contaminated". They were characterized by a predominance of plankton and plankton and benthos, eurythermal, and indifferent in relation to water salinity and pH algal species. Valid correlation was established between the concentration of ammonium and phytoplankton biomass, and also between permanganate oxidizability and phytoplankton numbers.
