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 70 feet in segmented cascades stretching over six miles of the river's length. The average discharge of the cataract is nearly 3 million gallons per second, though the highest volume on record was reached at over 13 million gallons per second.
