An under-construction dam in southeast Laos collapsed on the evening of Monday, July 23rd, unleashing flash floods on nearby communities. An estimated 17.7 billion cubic feet of water had spilled over the dam, enough to cover an area the size of Manhattan in water 28 feet deep. At least 27 people have been killed, and many more remain missing, as well as displacing at least 6,600 others. State media reports that as many as 25,000 more people were being evacuated. Rescue efforts are underway, but flood levels could rise with expected rainfall.
