Nepal Barrier Lake Breaches Banks, Raising Fresh Flood Threat
A mudslide in Nepal created a lake near the border with China.
The lake was held back by a natural wall of earth.
That wall broke or started to overflow.
The water level then began rising.
This could send more water downstream and cause new floods.
China warned people about the danger and paused rescue work on its side.
China also sent an engineering team to help assess the situation.
Nepal stopped rescue work for about 90 minutes while officials checked the risks.
A barrier lake formed after a mudslide in Nepal’s Rasuwa District on Wednesday.
Nepal officials said the lake’s embankment along the Nepal-China border gave way and water levels were rising.
The lake began overflowing, raising concerns about another surge of water downstream.
China warned of fresh flooding, paused rescue efforts on its side, and deployed an engineering team.
Nepal authorities halted rescue operations for about 90 minutes as officials assessed the danger.
