Fly River Crossing Papua New Guinea7.4S 141.0E
Visible as a tan line crossing Papua New Guinea from the center to the center-bottom of this image is the Fly River. At 1,050 kilometres (650 mi) in length, it is the second longest river in the country. The Fly is the largest river in Oceania, the largest in the world without a single dam in its catchment, and overall ranks as the twenty-fifth largest river in the world by volume of discharge.
The Fly River rises in the Victor Emanuel Range arm of the Star Mountains, and crosses the south-western lowlands before flowing into the Gulf of Papua in a large delta. The river flows mostly through the Western Province, though for a small stretch it forms the boundary between Papua New Guinea and the Indonesia province of Papua.
