Ten days in total darkness can strip a person of everything except instinct. When 30-year-old hydropower worker Sanjay Sah finally saw daylight after a disaster response team broke through to him, his mind was so disoriented his first words were simple and startling. "How many days has it been?" He thought only a short time had passed. In reality, a catastrophic flash flood had transformed the mountain tunnel he worked in into an underwater trap for nearly a week and a half.
The August 26 disaster caught workers off guard when a massive glacial collapse on the China-Nepal border sent tsunami-like waves roaring down river valleys. The human toll was devastating, killing over 1,400 people and leaving thousands missing, mostly across Nepal. But stories like Sah's offer a look at the sheer endurance required when modern infrastructure fails against sudden climate extremes in the Himalayas.
The Strike of the Mountain Waters
Workers received early alerts that high water was coming, but the speed of the surge left virtually no time to clear the complex network of hydropower tunnels. When the water hit, it rushed through the subterranean chambers with immense kinetic force. Sah was on duty when the torrent trapped him underground.
Surviving the initial impact required hanging onto whatever metal or infrastructure was within reach. Raging water filled the lower sections, forcing workers to climb onto trucks, elevated platforms, and pipes. The physical danger was immediate, but the psychological toll of isolation proved equally punishing. Sah leaned heavily on his faith to anchor his mind. He chanted Hindu prayers, focusing his energy inward to fight off panic as he stood knee-deep or waist-deep in cold water.
Ten Days on Muddy Water and Resilience
Water is life, but underground after a flood, the only available hydration was thick, muddy runoff. Sah drank what he could find to stay alive while completely cut off from the outside world. He wasn't entirely alone in the subterranean labyrinth—another worker, Kabir Maharjan, was trapped nearby, and the two men managed to communicate across the dark distance. Hearing another human voice became a lifeline, keeping despair at bay while rescue teams raced against time above ground.
Outside, families kept vigil. Sah's wife, Lakshmi Kumari Sah, refused to give up hope as days dragged on without news. Rescue operations involving the Nepali Army and local authorities faced monumental obstacles, having to clear massive blockages of mud and debris just to inch forward through the tunnels.
The Miracle Rescue and What Comes Next
On September 4, emergency teams finally broke through and pulled Sah and Maharjan to safety. Covered in mud and physically depleted, they were rushed to a hospital in Kathmandu for urgent care. While the rescue brought immense relief, Sah's emotions remain mixed. He calls his survival a second life, yet he mourns the colleagues who didn't make it out.
The catastrophe has laid bare the extreme vulnerabilities of hydropower projects tucked into vulnerable Himalayan gorges. As search efforts wind down, survivors like Sah remind us how fragile human infrastructure is when faced with the raw power of melting glaciers and unstable mountain terrain.
