The Dhauliganga is a turbulent Himalayan river which rises in the border regions of India and China and flows south into the Garhwal region of Uttarakhand, India. It joins the Alaknanda, the major source stream of the Ganges river.
On 7 February 2021, part of Nanda Devi Glacier, a Himalayan glacier in the Nanda Devi National Park, broke away and caused water levels in the Rishiganga and Dhauliganga rivers to rise. The Dhauliganga Dam at the Dhauliganga hydropower project at Reni village () was destroyed and another suffered partial collapse. Initial reports said nine people were killed and 140 missing. Water levels on the Alaknanda also rose. ==References==
