2025 Uttarakhand flash flood


The 2025 Uttarakhand flash flood occurred on 5 August 2025 in Uttarkashi, Uttarakhand, India. The disaster killed at least five people and left more than 50 others missing.

Cause

The cause of the event is still investigated. Media initially reported a cloudburst as the trigger for the disaster, but scientists are now exploring the possibility that a glacial lake outburst flood (GLOF), a glacier collapse, a landslide, or a combination of those different events may have caused the Kheer Ganga river to overflow with immense force. The floodwaters, carrying a large amount of debris and mud, tore through the Dharali village and surrounding areas. The India Meteorological Department had previously issued a warning for heavy rainfall in the region until 10 August.

Casualties and damage

The debris flow caused widespread destruction, particularly in the Dharali village, which lies on the pilgrim route to Gangotri Dham. Initial reports confirmed five fatalities, with many more people feared missing. More than 70 people were presumed dead as of 14 August. The Indian Army said injured individuals are receiving medical treatment at the Indian Army medical facility in Harsil. Locals estimate that hundreds of people could possibly be trapped under the debris. Dramatic visuals from the scene showed houses, shops, and other infrastructure being crushed and obliterated by periodic waves of boulders and mud. The Dharali market was submerged, causing a fear of several casualties. Preliminary assessments suggest that at least 50 hotels were destroyed and around 40–50 houses were swept away. A portion of the Harsil Army camp and helipad was damaged by debris flow. Eleven soldiers were reported to be among the missing.

Rescue operations

Upon receiving news of the disaster, the Indian Army's Ibex brigade, along with teams from the National Disaster Response Force
and State Disaster Response Force, were immediately mobilized and dispatched to the affected areas. The Uttarkashi district magistrate confirmed that rescue teams are currently assessing the extent of the damage and are engaged in search and rescue operations. Uttarkashi police have urged residents and tourists to stay away from the swollen rivers. Chief Minister Pushkar Singh Dhami was in contact with senior officials to monitor the situation and oversee relief efforts. Dhami said 190 people were successfully rescued.
Two Boeing CH-47 Chinooks, two Mil Mi-17s, an Aérospatiale SA 315B Lama and a HAL Dhruv of the Indian Air Force were placed on standby as poor weather hampered rescue operations.
By late August 2025, the Air Force, from its Northern Secor, deployed five of its Mi-17 helicopters along with a Chinook and C-130J transport aircraft each for the flood relief operations following the Uttarakhand and Kishtwar district flash floods. The C-130J aircraft boarded by an NDRF team reached Jammu to supply rescue materials, supplies and trained personnel. So far, 50 Army personnel, 21 BSF personnel and over 40 civilians have been rescued by the fleet from regions including Akhnoor, Pathankot and Dera Baba Nanak. Additionally, over 750 kg of relief materials were also air dropped into Pathankot as part of the operation. Additional helicopters and transport aircraft also remained on standby to join the operations if deemed necessary.

Aftermath

The uttarakhand flash flood and cloudburst had a significant impact on the region's infrastructure and travel. The disaster led to the disruption of connectivity to Gangotri Dham, and the Char Dham Yatra was impacted by rain-triggered landslides and flash floods. The IMD's forecast for continued heavy rainfall raised concerns about the potential for further emergencies. The events in Uttarakhand and other parts of the Himalayan region, such as Jammu and Kashmir, have highlighted the devastating effects of extreme weather, and officials are maintaining round-the-clock vigilance in vulnerable zones. Residents in the affected areas were in a state of shock, with many families displaced and businesses in ruins. A second cloud burst struck Sukhi Top near Dharali shortly after the first. The extent of the damage is currently being assessed.

Geological and hydrological impact

A temporary lake approximately 400-500 m long formed upstream in Harsil, raising fears of further flooding if the natural dam were to breach. The IMD issued warnings of continued heavy rainfall through mid-August.
