Description

The headwaters are located on the sandstone plateau fed by springs in Arnhem Land at an elevation of 274 metres (899 ft) and flows in a northerly direction through mostly uninhabited lands and eventually discharges into Junction Bay and the Arafura Sea. The only tributary of the river is the Gumardir River.

The estuary formed at the river mouth is in near pristine condition and occupies an area of 24.9 hectares (62 acres) of open water. It is riverdominated in nature with a tide dominated delta having a single channel and is surrounded by an area of 11.2 square kilometres (4 sq mi) covered with mangroves.

The catchment occupies an area of 5,684 square kilometres (2,195 sq mi) and is situated between the East Alligator River catchment to the west and the Liverpool River catchment to the east. It has an annual discharge of 1,140 gigalitres (1.491×109 cu yd).

Flora and fauna

The riparian vegetation of the river is in good condition but are declining as a result of the proliferation of feral pigs and buffalo and the invasion of some weed species.

19 species of fish are found in the river including; the Macleay's Glassfish, Barred Grunter, Sooty Grunter, Fly-specked Hardyhead, Northern Trout Gudgeon, Gulf Saratoga, Barramundi, Oxeye Herring, Rainbowfish, Black-banded Rainbowfish, Bony Bream, Catfish, Freshwater Longtom, Seven-spot Archerfish and the Sleepy Cod.

The pig-nosed turtle, a threatened species of turtle, is known to inhabit sections of the river, but only in small populations.
