Aquatic ecosystems are in balance with the external environment factors and have a complex system of biological connections, disturbed under the influence of anthropogenic factors. First of all, the influence of anthropogenic factors affect the taxonomic composition of aquatic communities. Assessment of the degree of water pollution on the composition of living organisms to quickly establish its ecological condition. In summer 2016 the first time studied the planktonic algae Kuchane Lake located in Pushkinogorsky district of the Pskov Region on the territory of the Museum-Reserve of A.S. Pushkin Mikhailovskoye. Phytoplankton is one of the main components of the aquatic ecosystem, quickly responding to any changes in the environmental conditions, and its structural characteristics are the important elements in evaluating the ecological state of the pond. The article discusses the use of phytoplankton to assess the water quality of Kuchane Lake. Showed taxonomic composition of phytoplankton of the lake in the summer. Algae is characterized by relatively high species diversity. One hundred twenty six species taxa of phytoplankton belonging to 8 phylums were identified during the research: Chlorophyta (45), Bacillariophyta (38), Euglenohyta (15), Cyanophyta/Cyanoprokaryota (9), Dinophyta (7), Chrysohyta (6), Сryptophyta (5), Xanthophyta (1). The basis of phytoplankton up green and diatoms. Investigated ecological and geographical analysis of phytoplankton and saprobiological analysis of the quality of the lake water.
