The present study used Landsat-8 and Sentinel-2A data to prepare an updated and detailed glacial lake inventory of Dibang river basin for the year 2020. Furthermore, Landsat-5 TM (1985) data was used to analyze the spatio-temporal dynamics of selected glacial lakes having size greater than 0.1 km2. The study reveals 403 glacial lakes having size >0.01 km2 and 55.73 km2 of total area in 2020. Area of selected lakes has shown a clear growth in area from 29.96 km2 in 1985 to 32.56 km2 in 2020, thus a total area of 2.60 km2 has increased over the period of 35 years at the rate of 0.07 km2/year. A total of 16 Potentially Dangerous Glacial Lakes (PDGLs) and 6 Most Vulnerable Glacial Lakes (MVGLs) were identified in the region using various parameters reported in the scholarly literature. Hence, we suggest continuous monitoring and assessment of PDGLs and MVGLs in the study region.
