Nam Ou

The Nam Ou (Laotian: ນ້ຳອູ [nâːm ùː], literally: "rice bowl river") is one of the most important rivers of Laos. It runs 448 km from Phongsaly Province to Luang Prabang Province.^[1] The river rises in Muang Ou Nua near the Lao-Chinese border, and traverses the northern Laos mountains and gorges until meeting the Mekong River in Ban Pak Ou.^[2] Along with the Mekong, the Nam Ou is the only natural channel suitable for large-draft boat transportation. The Nam Ou is one of the 12 principal tributaries of the Mekong River.^[2] The river has a total area of nearly 26,000 km².^[3] Near its confluence with the Mekong are the Pak Ou Caves, famous for their Buddha statues. The river is also surrounded by limestone karts, forests, and valleys. The river supports Lao rice cultivation. The Nam Ou placed in the top 80th percentile for river health according to the Mekong River Commission's aquatic health index.^[3]
