Songkhram River

The Songkhram River (RTGS: Maenam Songkhram, pronounced [mɛ̂ː.náːm sǒŋ.kʰrāːm], Northeastern, pronounced [mɛ̄ː.nȁːm sǒŋ.kâːm]) is a tributary of the Mekong River. It originates in the hills between Nong Han District, Udon Thani Province and Sawang Daen Din District, Sakon Nakhon Province. It flows through Seka District (Nong Khai Province), Wanon Niwat (Sakon Nakhon Province), and Si Songkhram District and empties into the Mekong River in tambon Chai Buri, Tha Uthen District, Nakhon Phanom Province. It is 420 kilometres (260 mi) long. The Songkhram is one of the more important but lesser known rivers in Thailand's northeast. It is the last Mekong tributary in Thailand free of developments blocking river flow. Fish can swim freely into the Songkhram River from the Mekong and use it as a spawning ground. This replenishes the fish stocks that are an indispensable food source for inhabitants of the Mekong region.

Flows through: Thailand.
