The Irrawaddy River is formed by the confluence of the N'mai and Mali Rivers, both being fed by the glaciers of the Himalaya Mountains. The river flows from north to south for 2,170 kilometers and enters the Andaman Sea. The Irrawaddy has served as an important waterway for Myanmar since the early 16th century. The mouth of the river forms the Irrawaddy Delta, an important agricultural region able to produce a substantial portion of Myanmar’s rice. Two thirds of the delta is dedicated to growing rice.
