Time is running out in the rugged terrain of Nuwakot. Heavy floods have locked down the Upper Trishuli hydropower site, leaving workers stranded deep underground and emergency crews racing against a ticking clock.
You're looking at one of the most tense technical rescue operations in recent Himalayan history. Following devastating flash floods, the Upper Trishuli tunnel rescue has entered its most critical phase. Military teams, technical specialists, and international experts are fighting every hour to reach dozens of men trapped inside a dark, waterlogged underground labyrinth.

The Ground Reality in Nuwakot
The situation on the ground is chaotic and physically brutal. Flash floods slammed the region on August 26, crippling infrastructure across Rasuwa and Nuwakot districts. Independent power associations reported that nearly nine hundred workers and staff across multiple projects went missing in the immediate aftermath.
At the center of this crisis stands the Upper Trishuli project. The numbers don't paint a clear picture yet, which makes the rescue mission even harder. Military estimates suggest at least 35 individuals are trapped inside the main conduit. Meanwhile, local police assessments push that number much higher, near 200, based on shift logs and technical headcounts. For another angle on this development, refer to the latest coverage from USA.gov.
Nobody knows the exact body count waiting in the dark. That uncertainty turns every drilling decision into a high-stakes gamble.
Breaking Through the Crown
Rescue teams didn't just walk in. They had to cut their way through solid rock and debris.
After three grueling days of round-the-clock drilling, excavating, and using heavy hydraulic cutters, the Nepali Army managed to locate the crown—the absolute uppermost section—of the Upper Trishuli tunnel.
Army spokesperson Rajaram Basnet noted that drilling a specialized entry hole revealed an alarming sight. The water level inside the seven-meter diameter tunnel extends dangerously high up.
Despite pumping water and drilling emergency oxygen inlets to keep anyone trapped alive, the first breakthrough teams met complete silence. When rescuers shouted into the newly drilled access port, nobody answered back. It's a heavy psychological blow, but hope persists because oxygen lines are active. Workers are estimated to be stuck roughly 180 meters deep from the primary entry point.
International Help Steps In
Local resources hit their absolute limit days ago. Nepal's military is stretched thin, managing multiple landslide and flood zones simultaneously across the country.
That's why foreign technical aid arrived swiftly. An Indian Air Force contingent touched down with specialized gear, thermal imaging, and DNA collection kits deployed at Syafrubesi. At the same time, a Chinese technical unit landed in Kathmandu equipped with advanced drilling machinery, air-pumping systems, and thermal sensors, taking position at Hakubesi.
Heavy machinery, controlled blasting, and widening the tunnel crown are now underway to speed up the entry of rescue specialists carrying cameras and portable oxygen supplies.
The next few hours will determine the fate of everyone trapped inside. If you're tracking this disaster, keep your eyes on the tactical updates coming out of Nuwakot as heavy equipment finally punches a wider path underground.
