Bottom sediments of the Lake Plescheevo is a valuable lake record for the central part of the East European Plain. During this study, we analyzed the lithological characteristics of the upper 4 m of the lake sediment and calculate the sedimentation rate and mass accumulation rate of the lace sediments during last 3500 years. We established that the main part of the increase in the mass accumulation of the Lake Plescheevo bottom sediments is due to the silicate deposits associated with the introduction of terrigenous material into its water area. High values of mass accumulation rates about 3500-3000 cal BP. correspond to a stage of high fluvial activity for the East European Plain. The rapid increase in the rate of mass accumulation rate in the last few decades may be associated with the anthropogenic impact - possibly with the influence of a dam on the Vyoksa River flowing into the lake.
