The changing climate in the 20th and 21st centuries has had a profound impact on glacial lake formation and downwasting. The rapid receding of glaciers due to increased atmospheric temperature has caused glacial lake outburst floods (GLOFs) in the nival–glacial belt region on the northern slopes of the Kyrgyz mountain range over the last 20 years. Catastrophic events downstream due to GLOFs are increasing in this region and could affect the natural environment, human lives, and property. This study aims to evaluate the spatial distribution and growth of glacial lakes on the northern slopes of the Kyrgyz range using semiautomated remote sensing and field techniques. We recorded 273 glacial lakes and examined the characteristics of 5 small GLOFs that occurred between 2000 and 2012 due to moraine collapse. Further, the findings highlight alarmingly rapid changes and a high probability that these lakes will burst soon. Remote sensing, geographic information system, and statistical techniques combined with field-based knowledge are effective in identifying and monitoring the catastrophic nature of GLOFs on the northern slopes of the Kyrgyz range. The study recommends creating a spatial database inventory of both glacial lakes and GLOFs in the region using high-resolution satellite images and in-situ field techniques
