New glacial lake poses flood risk at Nepal-China border

A previously undetected lake is swelling at an alarming rate near Nepal's border with China, raising concerns about potential downstream flooding in both nations. Satellite analysis shows the lake has formed above the Rasuwagadhi crossing point, where accumulated debris has obstructed the Lhende River's normal flow.

The obstruction appears to have been caused by rockfall or glacial material, creating a natural dam that is allowing water to accumulate at an accelerating pace. Remote sensing data indicates the lake continues to expand, prompting authorities in both countries to monitor the situation closely.

Authorities have issued new flood warnings for settlements downstream as a precautionary measure. The formation of such lakes, often triggered by glacial retreat or unstable mountain terrain, poses a significant hazard in the Himalayan region, where catastrophic outburst floods can occur with little warning.

The Rasuwagadhi border crossing, a key trade route between Nepal and China's Tibet region, lies directly downstream of the developing lake. Officials are assessing whether the situation poses an immediate risk to infrastructure or populations in the area.
