**Khone Falls**

Khone Falls rapids
Location	Mekong River Champasak Province Laos
Type	Tiered
Total height	21 m (69 ft)
Watercourse	Mekong River

The Khone Falls is a waterfall on the Mekong River in Laos in the Champasak Province near its border with Cambodia. The Khone Falls are the main reason that the Mekong is not navigable into China.

The falls' total height is 21 meters (69 feet) in segmented cascades (or rapids) stretching over 10 kilometers (six miles) of the river's length. The average discharge of the cataract is nearly 11,000 cubic meters per second (3 million U.S. gallons per second), though the highest volume on record was reached at over 49,000 cubic meters per second (13 million U.S. gallons per second).

The area of the falls is dotted with islands and countless waterways, known as Si Phan Don (meaning 4000 islands).

[edit] Navigable efforts

The Khone Falls are well known as the prime reason why the Mekong river is not navigable into China. In the late 19th century French colonialists made repeated efforts to navigate the falls but they all failed. The first time they succeeded in bringing vessels of any size to the part of the river above the falls was when they had built a railway between two islands on the falls, circumventing the steepest rapids and allowing trans-shipment.

[edit] Plabuck in the falls

The falls are home to the plabuck, an endangered species of catfish said to be the largest freshwater fish in the world. The plabuck is alleged to reach lengths of 3 meters (10 feet) and weights of up to 646 pounds (293 kilograms). ^[1]
