Nepal plans to drain four glacial lakes after deadly floods - Reuters

Heavy monsoon rains in August triggered a deadly flooding disaster across Nepal, causing widespread damage and loss of life. The flooding, which swept through low‑lying valleys and river basins, prompted authorities to reassess the country's vulnerability to water‑related hazards.

In response, the Nepalese government announced a plan to drain four glacial lakes situated in the high Himalayas. The initiative is aimed at reducing the risk of sudden glacial lake outburst floods that could exacerbate future flood events in downstream communities.

Officials indicated that the drainage works could take up to six years to complete. The project will involve engineering measures to lower water levels in the lakes safely, with the goal of stabilising the surrounding terrain and preventing uncontrolled releases of water.

The decision follows assessments that the rapid expansion of glacial lakes, driven by climate change and melting ice, has increased the potential for catastrophic outbursts. By lowering the lake volumes, authorities hope to mitigate the threat to populated areas and critical infrastructure.

The drainage program forms part of a broader effort by Nepal to strengthen disaster preparedness and improve resilience against extreme weather events, complementing other flood‑control and early‑warning initiatives underway in the country.
