Over the past one and a half months of the 2026 monsoon season (since June 24), at least eight (& counting) major accidents and disasters have affected hydropower and dam projects across the Himalayan region. In addition, two recurring landslide lakes have emerged as significant hazards that are either linked to HEP construction activities or have the potential to impact downstream hydropower infrastructure. Notably, these incidents span the Teesta, Brahmaputra, Chenab, Ravi, Beas, Sutlej and Yamuna basins underlining that almost no major Himalayan river basin remains untouched by recurring hydro-related disasters.
