Debris and Water Surge Into Uttarakhand Tunnel, Trapping Workers in Chamoli

Current Summary

A landslide sent debris and water surging into an under-construction THDC hydropower tunnel in Chamoli district on August 13, trapping workers inside. CM Dhami has said 22 workers were at the site, of whom 19 have now been rescued and 3 remain trapped, with operations continuing to reach them. Earlier reports gave conflicting death tolls: India Today reported seven dead and 14 injured, while Deccan Herald put the toll at six dead and 14 injured — a discrepancy that remains officially unresolved alongside the rescue count. Underwater rescue operations were earlier launched to locate workers trapped. CM Dhami has been at the site monitoring operations, which continue at war footing. The precise location within the project, the lead rescue agencies, and a final officially confirmed casualty count have not been disclosed.
