Nam Theun River

Nam Theun river is a river in Laos that flows through the provinces of Khammouane and Bolikhamsai. It has a total length of 138 km (86 mi) [a] and drains an area of 2,800 km2 with its tributaries Nam One, Nam Noy, and Nam Theun (1,100 sq mi).

Nam Theun River also refers to three dam alternatives on the same river: Nam Theun 1, Nam Theun 1-2, and Nam Theun 2. Nam Theun 2, the most cost-effective of the three choices, is now operational. A 62,000-hectare national park, part of the river corridor, is one of Laos' protected places. The Nakai-Nam Theun Biodiversity Conservation Area (NBCA), located upstream of South Theun, is one of Southeast Asia's most pristine areas.

The Truong Son mountain range and the Nakai Plateau are part of the Nakai-Nam Theun region, which spans 3,445 kilometers in Khammouan and Bolikhamxai provinces. This location is close to Vietnam's Vu Quang National Park. The management headquarters are situated in Muang Nakai's capital city. In the South Kading National Reserve in Laos, a 62,000-hectare river corridor was built in 1993.
