Explanation:

The present glacial lake atlas is based on the inventoried glacial lakes in part of Ganga River basin from its origin to foothills of Himalayas covering a catchment area of 2,47,109 sq. km.

• The study portion of Ganga River basin covers part of India and transboundary region.
• The Atlas is available on Bhuvan portal of NRSC, ISRO, India WRIS Portal and National Hydrology Project (NHP) web site of DoWR, RD & GR.
• The expected utility of the atlas is:
• The atlas provides a comprehensive and systematic glacial lake database for Ganga River basin with size > 0.25 ha
• In the context of climate change impact analysis, the atlas can be used as reference data for carrying out change analysis, both with respect to historical and future time periods
• The atlas also provides authentic database for regular or periodic monitoring changes in spatial extent (expansion/shrinkage), and formation of new lakes
• The atlas can also be used in conjunction with glacier information for their retreat and climate impact studies.

Hence only statement 1st is correct.
