摘要：

Based on the data of long-term studies of phytoplankton, an assessment of the current ecological state and the direction of changes in the Saltaim-Tenis lake system (Omsk region) has been carried out. Species composition, structure, abundance, and dominant complexes of phytoplankton are described. The predominance of cyanobacteria in the formation of the population and the dominant phytoplankton complex is established. The trophic level of the lakes corresponds to the eutrophic and polytrophic water category. The saprobity index of water varies from the alpha-oligosaprobic to the beta-mesosaprobic zone. Compared to the mid-20th century, the ecological state of the lake system is stable.
