Minbu is a city in Magwe Division, Myanmar. As of 2014, the city has an urban population of 22,962. The area consists of low plain-land towards the Ayeyarwady River, and of undulating country inland rising higher and higher westwards towards the Arakan Mountains. Between the plain and the Arakan Yoma range is a distinct line of hills running north and south, and usually called the Nwa-Madaung hills. The chief streams besides the Ayeyarwady are the Mon, the Maw, and the Salin, which are largely used for irrigation. At Minbu the Ayeyarwady is 3 miles (4.8 km) wide, with many islands and sandbanks. There are considerable fisheries along the Ayeyarwady and on the Paunglin Lake, which is a lagoon fed from the Ayeyarwady. Oil has been discovered near the mud volcanoes of Minbu, but it seems to lie at too great a depth to be profitably worked.
