The average long-term ratios of biogenic elements in atmospheric precipitation and the surface layer of lake water in the cold and warm seasons are analysed. It is shown that the role of atmospheric precipitation in the formation of primary lake production may be underestimated. Directions for more detailed research of the role of atmospheric nitrogen and phosphorus inputs in the functioning of the lake ecosystem are proposed.
