The Khone Falls and Pha Pheng Falls (Lao: ນ້ຳຕົກຕາດຄອນພະເພັງ; Khmer: ល្បាក់ខោន, Lbak Khaon) together form a waterfall located in Champasak Province on the Mekong River in southern Laos, near the border with Cambodia. It is the widest waterfall in the world at 10,783 metres (35,376 feet or 6.7 miles) in width from one edge of its multiple channels to the other.[1][2]
The Khone Falls are the largest in southeast Asia, and are the main reason that the Mekong is not fully navigable into China. The falls are characterised by thousands of islands and countless waterways, giving the area its name Si Phan Don or 'the 4,000 islands'.
The highest falls reach to 21 metres (69 ft); the succession of rapids stretch 9.7 km (6.0 mi) of the river's length. The average discharge of the cataract is nearly 11,000 m3/s (390,000 cu ft/s), with the highest flow on record at over 49,000 m3/s (1,700,000 cu ft/s).
