We consider the peculiarities of the process of sulfate reduction in three freshwater lakes with different anthropogenic impacts and groundwater types. Quantitative indicators of this process are presented. The results obtained are compared and the features of sulfate reduction in each of the reservoirs are highlighted. It is shown that the intensive sulfate reduction in water in summer is recorded for the most anthropogenically loaded lake. For a reservoir with the receipt of a sulfate type of groundwater, the process proceeds with the greatest accumulation of reduced sulfur compounds both in water and in bottom sediments.
