We provide a characterization of the natural formation factors for the chemical composition of the waters in the lakes of Polar Ural. Morphometric and hydrodynamical characteristics of the lakes are given. The lakes under consideration are notable for ultrafresh (ranging from weakly acidic to alkaline), hydrocarbonate and, more rarely, sulfate-hydrocarbonate waters, with different cationic composition. An investigation into the interrelationship of morphometric and hydrodynamical characteristics of the lakes revealed a special role played by the runoff function in the formation of the chemical composition of the waters in the lakes under study.
