The paper presents the results of the remote sensing studies of distributions of small thermokarst lakes’ sizes using Canopus-V satellite images with high spatial resolution (2 m) obtained during the summer months of 2013–2014. In this research, a total of 18 test sites have been investigated within the area of discontinuous permafrost in Western Siberia. Results of the interpretation of satellite images have allowed determining the number of lakes, their areas, and limnicity of the territory for each test site. It has been determined that the size-distribution of small thermokarst lakes within the study area corresponds to a power law.
