    We studied the atmospheric deposition of phosphorus (P) forms along an elevation gradient and its contribution to the total external P loading of alpine and forest lakes. The aim was to evaluate how topographical (soil and vegetation pools in the catchment) and morphological (catchment to lake area ratio) characteristics of catchment–lake systems affect in-lake nutrient structures in remote mountain areas. The C:N and C:P ratios of external nutrient inputs to the lakes were higher for terrestrial than atmospheric sources and the relative atmospheric contribution to the total external P loading of lakes was inversely related to the soil cover of catchments and the ratio between catchment and lake areas. The different composition and proportion of terrestrial and atmospheric nutrient inputs to mountain lakes along the vegetation zones determine the stoichiometric balance between the DOC and P available as nutrients for the food webs of natural mountain lakes.
