Geographical and Geological Background

Gangapurna Lake was formed by glacial melt from the surrounding Himalayan giants, including Mount Gangapurna, Annapurna III and IV, and Tilicho Peak. Over decades, sedimentation from the glacier and moraine activities helped shape the lake’s basin.

The lake sits just below the Gangapurna Glacier, which is retreating due to climate change, affecting the size and water level of the lake over time. The turquoise color of the water is due to rock flour (fine glacial silt) suspended in the water, reflecting sunlight in a unique way.

Environmental Concerns and Climate Change

Like many glacial lakes in the Himalayas, Gangapurna Lake faces ecological threats due to glacial retreat and rising temperatures.

Key Concerns:

• Shrinking glacier feeding the lake

• Sedimentation gradually filling the lake basin

• Potential threat of Glacial Lake Outburst Floods (GLOFs) in the region

Researchers and environmentalists monitor the area to study long-term climate impacts in the Annapurna Conservation Area Project (ACAP) zone.
