Nepal Disaster: How Nepal Raced to Drain a Glacial Lake Before It Could Destroy an Entire Valley

Nepal Disaster: How Nepal Raced to Drain a Glacial Lake Before It Could Destroy an Entire Valley High in the Nepalese Himalayas, a glacial lake called Tsho Rolpa grew from a small meltwater pond into one of the most dangerous bodies of water on the planet — over 100 million cubic meters of water held back by nothing but loose, unstable rock. A nearby lake had already burst a decade earlier, destroying a nearly finished hydropower project in minutes. Rather than wait for the same disaster on a larger scale, Nepali and Dutch engineers raced to lower Tsho Rolpa's water level using an excavated channel and a system of siphon pipes, working at 4,580 meters where the air holds half the oxygen of sea level. This is the story of how they did it, and how it became a blueprint for defusing glacial lake threats across the Himalayas. 📌 Disclaimer This video is created for educational and informational purposes only.
