Min Bu is a city in Magwe Division, Myanmar. As of 2004, the city has a population of 56,200. The area consists of low plain-land towards the Ayeyarwady River, and of undulating country inland rising higher and higher westwards towards the Arakan hills. 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 submontane valleys are largely cultivated, but are deadly except to those born in them[clarification needed]. The chief streams besides the Ayeyarwady are the Mn, the Maw, and the Salin, which are largely used for irrigation. At Minbu the Ayeyarwady is 3 miles 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.
