The modern state and functioning of the zooplankton community of Lake Munozero has been assessed. The species composition and dominant zooplankton complex of Lake Munozero has not changed since the 1950s. The Shannon–Weaver index in terms of biomass corresponds to the oligo- and mesotrophic type of lakes in the northwestern and southern areas of the lake, respectively. Saprobity indicators refer to the β-mesosaprobic zone (moderately polluted water). Seasonal changes in the zooplankton community correspond to the dynamics common for the lakes of Karelia. Zooplankton community of the southern area of Lake Munozero is under anthropogenic load, this is expressed in noticeable differences in the species composition, Shannon–Weaver index, saprobity index, and in quantitative and functional characteristics.
