The Barak River and its tributaries flow through the Barak Valley, which is located in the state of Assam, India. The river's tributaries include: Kushiyara, Katakhal, Jiri, Chiri, Modhura, Longai, Sonai, Rukni, and Singla. The Barak River is 564 kilometers long and flows through the states of Manipur, Mizoram, and Assam, before entering Bangladesh, where it splits into the Surma and Kushiyara rivers. These rivers then merge to form the Meghna river, which eventually forms the Ganges Delta. The Barak River's basin drains 52,000 square kilometers, of which 41,723 square kilometers is in India.
