About Ramu
The Ramu River is a major river in northern Papua New Guinea. The headwaters of the river are formed in the Kratke Range from where it then travels about 640 km (398 mi) northwest to the Bismarck Sea.
Along the Ramu's course, it receives numerous tributaries from the Bismarck Range to the south and the Finisterre and Adelbert.

History
For many millennia, people have lived along the river, and the river has formed the basis for food, transport, and culture.
The area encompassed by the Ramu was part of Kaiser-Wilhelmsland when Germany established German New Guinea in 1884. The Germans were quick to explore their territory, and the mouth of the Ramu was discovered in 1886 by Vice-Admiral Freiherr von Schleinitz after returning to Finschhafen from an expedition to the nearby Sepik. Schleinitz called the Ramu, Ottilien after his ship the Ottilie.
The course of the river was first discovered 10 years later in 1896 after Dr Carl Lauterbach, a botanist, led an expedition organised by the German New Guinea Company (Neu Guinea Kompagnie) to find the headwaters of the Markham River.
