Shintaphu glacial lake outburst floods Himalayan hot springs in Gasa, washing away infrastructure with no casualties reported.

A flash flood triggered by the bursting of the Shintaphu glacial lake has washed away infrastructure at the Gasa Tshachu natural hot springs in the Himalayan kingdom of Bhutan, state broadcaster BBS reported on Friday.

No injuries or loss of life had been reported from Thursday night's flood, though authorities said the full extent of the damage remained unknown because of darkness and the strong flow of floodwaters.

The flooding has cut off access to a major tourist destination in northern Bhutan and prompted safety advisories along two river valleys, while also raising concerns across the border in India. Glacial lake outbursts are increasingly linked to climate-driven warming in the Himalayas, and this event follows a similar flash flood that struck the same hot springs in 2021.

Damage and Safety Advisories

Two Bailey bridges, portable prefabricated structures, may have been washed away in the flood, according to BBS. The extent of the destruction was still being assessed as of Friday.

Kuensel, Bhutan's national newspaper, reported that part of the road leading to the village of Laya, where the springs are located, had been washed away and rendered impassable. The road has been closed to traffic indefinitely.

Residents along the Mochhu and Punatsangchhu river valleys were advised to remain vigilant and avoid riverbanks and flood-prone areas.

Background and Previous Incidents

Gasa Tshachu is a well-known hot springs destination in the northern part of Bhutan, a country nestled between India and China. The site draws significant tourist interest for its natural thermal waters.

The hot springs were previously hit by a flash flood in 2021, when the Mochhu River changed course and swept through the area. Glacial lake outburst floods occur when natural dams holding meltwater fail, releasing large volumes of water downstream and posing a recurring hazard in mountainous regions.

Concerns Over Artificial Lake and Cross-Border Impact

As authorities assessed the damage, Kuensel reported that concerns had emerged about a large artificial lake formed after flood-affected river channels conjoined following the outburst. Officials were monitoring the situation closely.

In neighbouring India, flood warnings were issued in parts of West Bengal and Assam following the glacial lake outburst, according to broadcaster NDTV. The warnings underscored the transboundary nature of the hazard posed by Himalayan glacial flooding.

Current Status and Next Steps

Authorities in Bhutan are continuing to assess the damage to roads, bridges and hot springs infrastructure. The road to Laya remains closed indefinitely, and residents in affected river valleys have been urged to exercise caution.

No casualties have been confirmed, and further updates are expected as daylight and receding floodwaters allow officials to complete a full evaluation of the affected areas.
