Bago River (Burmese: ပဲခူးမြစ်; Pegu River) is a river of southern Burma. It flows through Bago and Yangon. It arises in the hills of the Pegu Range and flows into the Myitmaka River which below that point is called the Yangon River. In 1608 the Portuguese adventurer Philip de Brito e Nicote, known as Nga Zinka to the Burmese, plundered the Shwedagon Pagoda. His men took the 300-ton Great Bell of Dhammazedi. De Brito's intention was to melt the bell down to make cannons, but it fell into this river when he was carrying it across. To this date, it has not been recovered.
