To date very little research has been carried out on zooplankton ecology in artificial reservoirs in Chelyabinsk region. The paper considers the current state of the zooplankton community in six reservoirs of the Chelyabinsk region (Russia). The species composition (32 species) and quantitative characteristics of the zooplankton community of reservoirs in summers of 2016 and 2017 were studied. The species common to all reservoirs belong to widespread palearct or cosmopolitan. It is studied the ratio of major groups. The results of the study showed that the share of Cladocera in mesotrophic reservoirs is 2.5 times higher than in eutrophic reservoirs. Unlike Cladocera , the Rotifera group is 10 times more abundant in eutrophic reservoirs compared to mesotrophic ones. Copepoda were common to all bodies of water, as they belong to widespread Palearctic or cosmopolitan. Changes in species diversity were recorded depending on the eutrophication of the reservoir. The increased anthropogenic load influenced the decrease in both the composition and the structure of zooplankton communities in water bodies.
