The Digul River (Dutch: Digoel) is a major river in South Papua province, Indonesia, on the island of New Guinea. It is the fourth longest river in New Guinea after the Sepik River, Mamberamo River, and Fly River. With a total length of 853 km (530 mi) and a drainage basin of 45,900 km2 (17,700 sq mi).[3]
History
The swamplands upstream were known by the name "Boven-Digoel" (Above the Digul, in Dutch) and hosted a penal colony at Tanahmerah (Red Earth) in the early 20th century, when Indonesia was a colony of Holland. As a result of the abortive 1926 revolt by the Communist Party of Indonesia (PKI), the Dutch exiled 823 of the most troublesome revolutionaries here.[4]
Hydrology
Rising on the southern slopes of the Maoke Mountains, the Digul flows first south and then west to empty into the Arafura Sea. For much of its length, it travels across a low region of extensive swamps and creates a delta near Dolak (Yos Sudarso Island, formerly Frederik Hendrik) Island. The river has a length of 853 km (530 mi) and is navigable as far as Tanahmerah.
