Sepik

Sepik

The Sepik River (/ˈseɪpɪk/) 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 (PNG) provinces of Sandaun and East Sepik, with a small section flowing through the Indonesian province of Papua.

The Sepik 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 drainage basins are the Fly River, the Mamberamo River (both also in New Guinea), and the Pechora in Russia. The Amazon River has no dams, but its tributaries do.
