Bamu

The Bamu River runs from the country south of Mount Bosavi through the swamp forests of the Papuan lowlands to the Gulf of Papua. Near its mouth the river broadens into a tidal estuary, fed by tributaries including the Wawoi and Aramia. Bamu, or Bamu Kiwai, is a Papuan language spoken along this river; its varieties include Upper and Lower Bamu.
