Context
Following the recent Glacial Lake Outburst Flood (GLOF) in Nepal, the Lahaul-Spiti district administration has decided to strengthen monitoring and precautionary measures for Ghepan Glacial Lake.
About Ghepan Lake
- Ghepan Lake, also known as Ghepang Ghat, is a high-altitude glacial lake in the Lahaul region of Himachal Pradesh.
- It is situated at an elevation of about 4,070 metres above sea level.
- The lake is associated with Ghepan, the protector deity of Lahaul, and holds cultural and religious significance for local communities.
- Three hanging glaciers supply meltwater to the lake.
Environmental Concerns
- Accelerated glacier melt over the past three decades has contributed to significant expansion of the lake.
- This reflects the wider effects of climate change in the Western Himalayas.
- The expanding lake raises concerns about a possible Glacial Lake Outburst Flood (GLOF).
- A GLOF occurs when water stored in a glacial lake is suddenly released, potentially carrying large quantities of water, rocks and debris downstream.
- Such an event can threaten settlements, infrastructure and ecosystems in downstream areas.
