GLOFs occur relatively infrequently, but are the most hazardous flood risk in the High Mountains, due to the impacts of Climate Change.

Imja Lake is located in Solukhumbu district, Khumbu region – a popular tourist destination in the country, is considered as one of the rapidly growing lakes in the Hindu Kush Himalayan region, which poses a high risk to the local inhabitants and thousands of tourists visiting the area every year.

In 2000, Department of Hydrology and Meteorology has successfully mitigated Tsho Rolpa Glacial Lake by lowering the lake level by 3 meter through the construction of drainage channel for controlled discharge of water, the first of its kind in Nepal.

The project aims to replicate the knowledge and experiences gained from Tsho Rolpa to mitigate GLOF risk arising from Imja Lake by reducing the lake volume through an artificial controlled drainage system combined with a community-based early warning system.
