The material was collected during the open water period from March to the end of November 2019. In the period of our research in the basin of the Chirchik river (Boshkizylsay river, Ugam river (pre-settlement site), Chirchik river) were discovered several types of zoobenthos and periphyton. The monitoring was carried out on 8 stations, in total of 64 quantitative samples of macrozoobenthos and periphyton were taken. Anthropogenic pollution causes changes in the composition and structure of aquatic communities, expressed in the change of dominant complexes of organisms, the simplification of the ecological structure, the appearance of highly saprobic species in the composition of the dominants.
