The Digul (Dutch: Digoel) is a major river in southern Papua province, Indonesia, on the island of New Guinea.[1]

History[edit]

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.[2]

Hydrology[edit]

Rising on the southern slopes of 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 (Frederik Hendrik) Island. The river has a length of 525 kilometres (326 mi) and is navigable as far as Tanahmerah.
