China Warns New Barrier Lake Could Trigger Another Nepal Flood
A river near the Nepal-China border was blocked by rocks and ice.
The blocked water formed a new lake upstream.
The lake is still getting bigger and could break through its barrier.
If that happens, a large amount of water could rush downstream and cause another flood.
China warned Nepal about this danger.
Nepal’s disaster agency told people near the lower river areas to stay alert and move to safer places.
The warning came after a deadly flood on Wednesday.
Authorities are still searching for missing people, rescuing residents and clearing damaged roads.
A blockage in the Lhende River upstream of Nepal’s Rasuwagadhi border has created a lake covering about 0.11 square kilometres.
China warned Nepal that the rising lake could breach and cause another major flood in the Bhotekoshi River system.
The lake could receive another 3 million cubic metres of water over the next three days, according to the report.
Nepal’s disaster authorities urged downstream residents, passengers and rescuers to remain vigilant and move away from riverbanks and risky areas.
The warning follows Wednesday’s deadly flooding, in which Nepal’s reported death toll reached 359 by Thursday evening.
