At least 115 households were evacuated and a town submerged after a dam collapsed early Thursday in the northern province of Quang Ninh; no casualties have been reported.
The secondary dam of the Dam Ha Dong irrigation dam broke at 5:30, flooding Dam Ha Town, the provincial paper quoted Hoang Giang, a Dam Ha District spokesman, as saying.
Giang said that incessant rains that began on Wednesday night overloaded the reservoir.
“Water began spilling over the dam wall at around 4 in the morning and collapsing one of the three secondary dams,” he said, adding that water level in the dam has increased to 60 meters deep at around 10:30 am on Thursday.
Dang Huy Hau, Quang Ninh's vice mayor, arrived at the site on the same day and oversaw the evacuation of 115 households in Dam Ha Town and Quang Tan Commune.
Relevant forces, including military units, were mobilized to repair the collapsed dam and provide emergency assistance as the flood waters began receding around noon on Thursday.
The material damages have yet to be calculated.
Located on the Dam Ha River, the Dam Ha Dong serves as a reservoir for the irrigation of nearly 3,500 hectares (8,648 acres) of agriculture land.
It also provides water to a community of roughly 29,000 people.
The VND500-billion (US$23.5 million) dam, which broke ground in 2006 and finished in late 2011, also prevents floods to the river’s lowlands.
