Sepik River

The Sepik River is the longest river on the island of New Guinea, and after the Fly and the Mamberamo the third largest by volume. The majority of the river flows through the Papua New Guinea provinces of Sandaun and East Sepik, with a small section flowing through the Indonesian province of Papua.

The Sepik, pronounced "sea-pick", is one of the great river systems of the World. It has a large catchment area and landforms that include swamplands, tropical rainforests and mountains. Biologically, the river system is possibly the largest uncontaminated freshwater wetland system in the Asia-Pacific region. The only larger rivers in the world with no dams in their catchments are the Fly, the Mamberano, and the Pechora in Russia.
