Mamberamo River
The Mamberamo (Indonesian: Sungai Mamberamo) is the second longest river on the island of New Guinea, after Sepik River (1,146 km) and third largest in Oceania by discharge (5,500 m3/s) volume after Fly River (7,500 m3/s) and Sepik (7,000 m3/s). It is located in the Indonesian province of Papua. It is the second largest river in Indonesia by volume of discharge after Kapuas River (6,500 m3/s) and also the widest. The river is formed from the confluence of its upper tributaries, the Tariku and Taritatu rivers in the Lakes Plains region, an interior basin with extensive freshwater swamp forests and grasslands. It flows northwards between the Van Rees Range (Pegunungan Van Rees) and Foja Mountains through a series of rapids and gorges. The last 160 km of the river are navigable. In the coastal lowlands the river is lined with marshes and forms a broad river delta. The Mamberamo discharges into the Pacific Ocean at the northern point of Point D'Urville or Cape Narwaku (Tanjung Narwaku). The river's huge valley is home to various uncontacted peoples and incredible biodiversity. In the 1990s, the Indonesian Government had plans to construct a large hydroelectric dam on the Mamberamo that would have submerged
