We report the results from a comprehensive hydrologo-hydrochemical investigation of the rivers and lakes in the upper reaches of the Multa river basin (Gorny Altai) as made in July–August 2008. The study revealed the characteristic features of the water regime, and the formation mechanism for dissolved matter runoff in an almost impassable portion of the mountain-glacier basin. Variations of the chemical composition indices of natural waters for a 75-year period have been estimated on the basis of analyzing the observational evidence from O. A. Alekin’s field expeditions in 1933, and the research findings obtained by the Land Hydrology Department of Moscow University in 2008.
