Kikori River
Gulf
The Kikori River, stretching 445 kilometers, is a significant river in southern Papua New Guinea on the island of New Guinea. Originating from the confluence of the Hegigio and Mubi Rivers in the southeastern Muller plateau, it flows southeast into the Gulf of Papua, forming a large marshy delta where the settlement of Kikori is located. The river basin spans diverse landscapes from alpine grasslands in the Southern Highlands to mangrove wetlands at the river's mouth. The region experiences high rainfall, averaging 5,900 millimeters annually, contributing to its lush environment and high sediment load. The Kikori catchment area is sparsely populated but ecologically rich, with notable biodiversity including over 100 fish species, many endemic, as well as unique freshwater turtles and crustaceans. The basin also hosts significant oil and gas fields, with infrastructure such as pipelines supporting extraction activities since the 1990s. Mount Bosavi, known for its biodiversity, lies on the western edge of the basin, highlighting the ecological importance of the region.
