Bhutan GLOF: NDRF on High Alert as India Adopts 'Whole-of-Government' Response
NDRF adopts a 'Whole-of-Government' approach to monitor the Bhutan Glacial Lake Outburst Flood (GLOF) and its potential impact on India.
Following reports of a Glacial Lake Outburst Flood (GLOF) in Bhutan, the National Disaster Response Force (NDRF) has placed its teams on high alert. While Director General Piyush Anand stated there is currently "no cause for concern," the Indian government has mobilized a comprehensive strategy to monitor potential downstream impacts on Indian territory.
A Unified Strategic Response
Speaking to reporters in Delhi on Friday, NDRF DG Piyush Anand revealed that the response is being managed under a 'Whole-of-Government Approach'. This governance model ensures that various ministries, departments, and public agencies operate in unison rather than in isolation to tackle complex crises.
Anand emphasized that this coordinated effort follows strict and clear directives from Prime Minister Narendra Modi and Union Home Minister Amit Shah. To ensure real-time monitoring and accuracy, the NDRF is working closely with key agencies, including:
- The India Meteorological Department (IMD)
- The Central Water Commission (CWC)
Threat to Assam and West Bengal
The alert comes after a reported outburst at Sintaphu Lake, located in Bhutan's Gasa district. The Central Water Commission (CWC) issued a special flood advisory on October 29, warning that a flash flood in the upper reaches of the Punatsangchhu River—known as the Sankosh River once it enters India—could lead to a sudden rise in water levels.
State-Level Vigilance
The advisory specifically highlighted the risk to the Alipurduar and Dhubri districts. In response, regional leaders have stepped up monitoring:
- Assam: Chief Minister Himanta Biswa Sarma confirmed that the state is closely monitoring vulnerable revenue circles in the Dhubri and Kokrajhar districts. He noted that state teams are in constant contact with the NDRF and urged residents to follow official updates.
- West Bengal: Tourism Minister Dr Sankar Ghosh stated that the administration is on high alert. While no devastating incidents have been reported in Alipurduar so far, precautionary advisories have been issued to ensure public safety.
Devastation in Bhutan
While India remains in a state of precaution, the impact within Bhutan has been significant. According to reports from Daily Bhutan, the outburst on the evening of October 29 caused substantial infrastructure damage:
- The Gasa Tshachu hot spring complex, situated beside the Mo Chhu river, was washed away by floodwaters.
- A section of the Punakha-Gasa Secondary National Highway was completely destroyed near the 31.85-kilometre mark, leading to the closure of the road.
- Floodwaters reached Taktsemakhang around 8:15 pm on Thursday, damaging roads leading toward Laya.
Authorities in Bhutan activated warning sirens and carried out precautionary evacuations in high-risk areas. Fortunately, as of the morning of October 30, no deaths or injuries had been reported.
The Geography of the Risk
The danger stems from the path of the water. Water from the high-altitude Sintaphu Lake—one of 17 glacial lakes officially listed as potentially dangerous by Bhutan—flows into the Mo Chhu. This river travels through Gasa and Punakha, where it meets the Pho Chhu to form the Punatsangchhu. This combined river eventually crosses the border into India as the Sankosh River, creating the potential for flash floods in the plains of Assam and West Bengal.
NDRF Day Tributes
Amidst the ongoing crisis management, DG Piyush Anand also took a moment to mark October 30 as the NDRF's official day. He paid tribute to the personnel of the force who have lost their lives in the line of duty, honoring their sacrifice and commitment to saving lives during national disasters.
