In this paper first data of the complex analysis of the hydrogen, oxygen and carbon isotope composition in waters and dissolved inorganic carbon (DIC) of the largest East Siberia river Vitim and some of its inflows are presented. The δD and δO values for waters under investigation indicating meteoric origin of waters and varies from -173,0 to -149,1 ‰ for hydrogen and from -23,3 to -20,2 ‰ for oxygen. Concentration of the DIC in waters depends on the type of landscape while δС values varies from -17,1 to -9,0 ‰ and pointed out the participation of soil diffusion and vegetative CO in formation of hydrocarbonate-ion.
