Abstract: The article, based on the catalog of glacial lakes, compiled from satellite images and data of specialized field studies for 2009-2017, presents the results of an assessment of the potential danger of breakthrough glacial lakes as a source of destructive glacial mudflows in the Ile (Zailiisky Alatau). The climatic changes on 6 meteorological stations located at the altitudes from 1100 to 3450 m above sea level are considered. According to the methodology of Kazselezaschita and known criteria of mudflow hazard assessment [Huggel et al. 2002] 17 most dangerous lakes were identified with definition of probable costs in case of their breakthrough.
