What is the longest river in the Northern Territory in Australia?

Answer 1

The Victoria River is published on the Australian Government Geoscience website as the longest, but the Katherine-Daly River figures indicate that this river is longer. These figures would need to be confirmed by more than one official scientific source before a definitive answer is published. This would then answer the question of the second longest river in the NT.

Also, some tributaries of the Victoria river may need to be verified for an accurate answer.

The internationally accepted measurement of a river is the total length from its furthest source to its end. This includes the distance from the source of its longest permanent tributarie/s. This source is therefore, also the river source.

With this in mind, the Victoria river is 510KM (unofficial), and the Katherine River 328Km (unofficial) combining with the Daly 361Km (unofficial) is a single river of 689Km.

Until this is verified by reliable official sources, no correct answer is available at this time.

Answer 2

The largest river in the Australian Capital Territory is the Murrumbidgee River, with a total length of 59km.

The Cotter River in the ACT is a major tributary of the Murrumbidgee River, draining the western area and providing most of Canberra's water supply from three storage lakes.

Answer 3

This is probably more of a perspective question and response than a definitive one due to many variables.

There is no 'One' Main river in the Northern Territory. But Darwin River can be considered the most important, population reliant wise.

Darwin and Palmerston, and many of its' rural neighbours, rely almost exclusively for its' water supply from Darwin River which flows into the recreational man-made Darwin River Dam.

Most major population centres, excluding Alice Springs and Tennant Creek, rely mainly on their own specific permanent waterway and, at times, their aquifers. To each area, these are the main rivers for their respective areas.

Katherine township relies on the majority of its' water from the Katherine River, and less frequently, on the Lime impregnated aquifers, or underground water supply, in the latter part of the the Dry season when the river flows the least, and may be subject to turbidity. Katherine is currently in the process of an environmental impact study into the building of an artificial recreational lake, similar to that of Darwin River Dam which may then place it as a contender for the Main River in some categories such as tourism, water supply, fishing, crocodile research, cane toad eradication research, CSIRO foodcrop research, and, recreation.

Alice Springs and Tennant Creek rely almost solely on aquifers and therefore are not considered in contention for the main river of the Northern Territory.

Tourism wise, it is contentious that the Adelaide River attracts most out of state visitors than any other single river destination due to it's renown jumping Crocodiles. But the Howard River, within Darwins' environs, may be more mainstream tourism due its' Barramundi hand feeding, recreational facilities, crocodile breeding centre and and close proximity to a major City.

Answer 4

According to the Australian Government's GeoScience website, the longest river in the Northern Territory is the Victoria River. Its official length is 510 km (not the 560km given in Wikipedia). It begins south of the Gregory National Park, and emptiles into the Joseph Bonaparte Gulf in the Timor Sea.

Answer 5

There is some dispute over this.

The Victoria River is published on the Australian Government Geoscience website as the longest, but the Katherine-Daly River figures indicate that this river is longer. The Victoria river is 510 km in length (unofficial), while the Katherine River 328 km (unofficial) combining with the Daly 361 km (unofficial) is considered by some to be a single river of 689 km.
