Threat of Lake Burst at China-Nepal Border Eases as Reservoir Shrinks

The perilous situation at the China-Nepal border has shown signs of easing as the threat of a lake formed after a devastating glacier collapse appears to be diminishing. Chinese authorities reported on Saturday that the risk of the lake bursting has decreased, as its size has shrunk, according to state broadcaster CCTV.

Satellite imagery from Thursday to Saturday morning revealed that water in the lake, situated at the confluence of two rivers straddling the border, has been gradually flowing through, reducing the reservoir size. The Water Resources Ministry reported that the lake's surface area was 99,000 square meters early Saturday morning, down by 21,000 square meters from Thursday's measurements – approximately the size of 14 football fields combined.

The glacier collapse on Wednesday triggered a massive torrent of rock, ice, mud, and debris that swept away a border port complex, killing hundreds and leaving thousands missing. The formation of the lake, created by the debris, raised concerns about secondary disasters, particularly for rescue operations in the area.

State-owned engineering and rescue enterprise China Anneng has been monitoring the lake since Thursday. The company dispatched a 15-member team on Friday equipped with reconnaissance drones, portable satellite stations, and mobile surveillance cameras to gather more data. An overflow from the lake on Friday temporarily halted rescue work, but further assessments deemed the risks manageable.

In addition to the lake at the site of the glacial collapse, authorities have flagged another larger body of water at the bottom of the glacier. "We estimate its area to be over 120,000 square meters, but its depth is currently unknown," said Chen Hongqi, a senior engineer at the Ministry of Natural Resources' Geological Disaster Technical Guidance Center.

Flood risks will remain until both lakes have fully drained, according to an official with Nepal's Disaster Management Authority. In the meantime, rescue workers continue their efforts amidst challenging conditions. On Saturday morning, over 50 rescue workers combed through the rubble of boulders and mud, searching for signs of life and calling out to survivors.

The first team of rescuers and a search-and-rescue dog reached the location of the Gyirong border crossing complex on Friday afternoon, describing it as nothing but ruins. The dangerous conditions at the main disaster zone, made more complex by road and communication disruptions, continue to pose significant challenges to the Chinese relief efforts, according to state news agency Xinhua.

China's death toll from the disaster rose to seven early Saturday, with 554 still missing. Nearly 500 villagers and construction workers, as well as all 555 tourists from the area, have been evacuated. The disaster has highlighted the fragility of the region and the potential for catastrophic events due to natural disasters.

As the situation stabilizes, authorities and experts are closely monitoring the lakes and the surrounding area to ensure the safety of the communities and to prevent further loss of life. The international community has offered support and solidarity to the affected nations, recognizing the severe impact of such natural disasters on vulnerable populations.
