For 933 workers buried after Nepal floods, time is against them
5 min readUpdated: Aug 31, 2026 12:33 PM IST
An estimated 933 people are still trapped in tunnels beneath 11 hydropower electric projects across Nepal, most of which are along the Bhotekoshi-Trishul river corridor devastated by the August 26 flash flood.
Many of the plants are in Rasuwa district, which is near the border with Tibet, and in neighbouring Nuwakot. Authorities believe many of the missing are either trapped inside silt‑filled tunnels or have been swept downstream.
Details about the missing or trapped workers is sketchy at this time, but data available at this time suggests the majority – over 500 – are from the Upper Trishuli 1 project, with another 122 from the Upper Trishuli 3B facility.
| Hydropower Project / Site | Missing (approx.) | Notes |
|---|---|---|
| Upper Trishuli‑1 | 576 | Largest cluster; Korea‑led project (Doosan/KOEN). Many feared trapped in tunnels or buried near weir/base camp. |
| Upper Trishuli‑3B | 122 | Major construction workforce along Bhote Koshi–Trishuli corridor. |
| Rasuwagadhi Hydropower Project | 93 | Significant damage reported at project site. |
| Upper Trishuli‑3A | 42 | Part of Upper Trishuli cascade in Rasuwa/Nuwakot. |
| Langtang River | 42 | Project on Langtang river system in flood‑affected district. |
| Chilime | 8 | Existing plant; tunnel access reported as extremely difficult. |
| Melung River | 7 | — |
| Rasuwa–Bhotekoshi | 4 | Smaller project in flood‑affected district. |
| Middle Trishuli Ganga | 2 | — |
| Trishuli Hydropower Project | 1 | — |
| Devighat Hydropower Project | 1 | Older plant on Trishuli river. |
| Total (approx.) | 900 | Figures as provided; subject to change as rescue operations continue. |

The Express aggregated data from multiple sources, including the Nepali government and global news reports, to arrive at a similar conclusion. The two Upper Trishuli projects account for over 700 missing people.
| Hydropower Project | Capacity (MW) | Missing (approx.) | Notes |

In a macabre race against time, rescue teams are working with experts from India and China to save as many as possible. But access to these tunnels has been compromised by the wall of mud and boulders that swept down the valley, causing cave-ins in each shaft.
Nepal has intensified rescue efforts to free hundreds of people trapped inside tunnels at hydropower projects, including the Trishuli-3A site, following Wednesday’s flash floods.

Pictures and videos shared by rescue teams show earth-moving equipment digging through tonnes of mud and rock, and working through the night. In one video Nepalese soldiers – deployed in large numbers to boost rescue ops – shine torchlights into a pit dug so rescuers can crawl into one tunnel.

“A large amount of debris has been deposited and that poses a big challenge…,” Army spokesperson Raja Ram Basnet told Reuters. “Our main focus is on opening the tunnels.”

Nepal Prime Minister Balendra Shah – who was sworn in less than six months ago after a violent student-led uprising – called the flood an ‘unprecedented and devastating natural disaster’ and has called for international aid for Nepal.
The floods have claimed over 900 lives so far and that number will increase over the next few weeks, as rescuers recover more bodies and re-establish links with remote areas cut-off after roads and bridges were destroyed. Over 4,200 people, including those in the tunnels, are still missing on the Nepal side of the border. An additional 546 are missing on the China side.
