On a bright, hot morning in the remote outskirts of the Trishuli valley, two workers from the Trishuli 3A Hydropower Project were pulled alive from a tunnel that had been sealed behind the sudden flood that demolished the region weeks earlier.
Local rescue teams, equipped with heavy machinery and a sound‑attuned GPS, navigated the rubble to reach the tunnel’s entrance. They then hauled the two men—one a young, local engineer and the other a seasoned laborer who had lived in the valley for decades—out of the water‑logged passage. The workers, while shivering and bruised, were greeted by the relief of an emergency k‑i21. They received bottled water and were transported to a medical facility for a full assessment.
The flood, which occurred near the Nepal‑China border, was a flash flood with no warning, which in turn was a result of a sudden burst of water from the mountain reservoirs and a catastrophic failure of a small culvert upstream. According to the hydrologists, the incident showed that the hydropower infrastructure was vulnerable to extraordinary events, especially in regions that have high rainfall, snowmelt, and mountainous terrains.
Indigenous communities in the valley, who manage land use, eco‑friendly energy initiatives, and local heritage sites, have existed in the area for several generations, and have been playing a vital role in collaborative efforts with the government. The heavy rains hit many people’s houses or home bases. The incident highlighted early warning systems that could better protect the tribal people that live in communities near the same place.
In addition to the immediate relief, discussions about water management reforms and the resilience of hydropower infrastructure continue. Indigenous experts, environmental scientists, and the government will work together to ensure that future projects can withstand the natural disasters that are growing with climate change or unpredictable seasonal variations.
