China’s Ministry of Water Resources has flagged a high risk of the barrier lake at the Chhochen‑Purep Sangpo confluence breaking within 72 hours, raising concerns for downstream areas in India that receive water via the Gandaki river.
The Ministry of Water Resources of China has issued a high‑risk alert that the barrier lake formed at the junction of the Chhochen and Purep Sangpo streams could breach within the next 72 hours. The warning was released after recent assessments indicated rising water levels and structural stress on the natural dam.
The lake sits in a remote part of the Tibetan plateau and feeds into a river system that becomes the Gandaki River once it crosses into Nepal. From there, the waters flow southward into the Indian states of Bihar and Uttar Pradesh, making any sudden release a trans‑border concern.
Indian and Nepali authorities have been notified of the Chinese warning and are closely monitoring river gauges downstream. Early‑warning mechanisms are being readied to alert communities in flood‑prone districts, and disaster‑management agencies are reviewing evacuation and relief plans.
Barrier lakes in the Himalayas have a history of sudden failures, often triggered by rapid snowmelt or seismic activity. While no immediate evacuation orders have been issued, officials stress that residents should stay informed through local bulletins.
The situation underscores the interconnected nature of Himalayan water resources and the need for coordinated monitoring among the three neighboring countries.
