Caddo Gap, Jun 12: People camping on in western Arkansas, known for its scenic beauty and countryside, turned victims to flash floods, which swept through a campground killing at least 16.
Heavy rains swelled the Little Missouri River to 20 feet (6 metres) leading to flash floods.
Officials informed that the victims were asleep in their tents at the Albert Pike campground in the Ouachita Mountains west of Little Rock.
While the death toll was reduced to 16 from the earlier eastimate of 20, the authorities are still unsure as to how many people are missing.
"There was a significant amount of rainfall last night and water quickly rose along the campsites," said Arkansas State Police spokesman Bill Sadler.
The footage of the flood sit showed cabins reduced to rubble and mobile homes and vehicles overturned by the waters.
