Rescue operations ended after six days [1] following a tunnel collapse in the Chamoli district of Uttarakhand.
The incident highlights the extreme risks associated with large-scale infrastructure projects in the fragile Himalayan terrain, where geological instability often complicates construction.
The collapse occurred on Aug. 13, 2024 [1] inside the race tunnel of the 444-megawatt Tapovan-Vishnugad hydroelectric project [1]. A surge of water and debris entered the tunnel, causing the structure to cave in [1]. The project is located near the Bheri River.
Reports on the casualties vary across sources. One report said that 10 people died [1], while other reports list the death toll as eight [2] or seven [3]. Initial reports indicated that 22 workers were trapped in the tunnel [3].
Rescue teams managed to save 12 workers from the debris [3]. Following those rescues, reports differed on the number of people remaining missing, with estimates ranging from two [2] to three [3]. Additional reports noted that 12 workers were injured [1].
The operation concluded with the recovery of the last missing worker. The recovery marks the end of the search and rescue phase at the site.

The disparity in casualty figures, ranging from seven to 10 deaths, reflects the chaotic nature of rescue efforts in remote mountain regions. This incident underscores the recurring tension between India's push for hydroelectric energy independence and the environmental volatility of the Uttarakhand region, where landslides and flash floods frequently jeopardize industrial sites.
