Location and features
Formed by the confluence of the Waterhouse River and Roper Creek, the Roper River rises east of Mataranka in the Elsey National Park and flows generally east for over 1,000 kilometres (620 mi) to meet the sea in Limmen Bight on the Gulf of Carpentaria. The river is joined by fifteen tributaries including the Chambers, Strangways, Jalboi, Hodgson and the Wilton Rivers. The river descends 126 metres (413 ft) over its 1,010-kilometre (630 mi) course and has a catchment area of 81,794 square kilometres (31,581 sq mi), which is one of the largest river catchment areas in the Northern Territory. The Roper River is navigable for about 145 kilometres (90 mi), until the tidal limit at Roper Bar, and forms the southern boundary of the region known as Arnhem Land. Mataranka Hot Springs and the township of Mataranka lie close to the river at its western end. Port Roper lies near its mouth on Limmen Bight.
The river has a mean annual outflow of 5,000 gigalitres (1.100×1012 imp gal; 1.321×1012 US gal).
Etymology
The first European to explore the Roper River was Ludwig Leichhardt in 1845 as he made his way from Moreton Bay to Port Essington. Leichhardt crossed the river at Roper Bar, a rocky shelf which conveniently lies at the high tide limit on the river. He named the river after John Roper, a member of the expedition.
