The 2021 Uttarakhand flood began on 7 February 2021 in the environs of the Nanda Devi National Park, a UNESCO World Heritage Site[1] in the outer Garhwal Himalayas in Uttarakhand state, India (Maps 1 and 2).[2] It is believed to have been caused by a landslide, an avalanche or a glacial lake outburst flood.[3] It has caused flooding in the Chamoli district, most notably in the Rishiganga river, the Dhauliganga river, and in turn the Alaknanda—the major headstream of the Ganges (Maps 2 and 3).[4][5] At least 72 people are confirmed to have been killed.[6]
