The Murrumbidgee River ( //) is a major river in the state of New South Wales, Australia, and the Australian Capital Territory (ACT). A major tributary of the Murray River, the Murrumbidgee flows 900 kilometres (559 mi) in a west-northwesterly direction from the foot of Peppercorn Hill in the Fiery Range of the Snowy Mountains, through the ACT, and to a confluence with the Murray.
The reaches of the Murrumbidgee in the Australian Capital Territory (ACT) are now affected by the complete elimination of large spring snow melt flows and a reduction of average annual flows of almost 50%, due to Tantangara Dam. Tantangara Dam was completed in 1960 on the headwaters of Murrumbidgee River and diverts approximately 99% of the river's flow at that point into Lake Eucumbene. This had extremely serious effects on native fish populations and other native aquatic life and has led to serious habitat loss. It is said that the Murrumbidgee River through the ACT is only half the river it used to be.[weasel words]
The mainstream of the river system flows for 900 km (559 mi). The river's headwaters arise from the wet heath and bog at the foot of Peppercorn Hill situated along Long Plain which is within the Fiery Range of the Snowy Mountains; and about 50 kilometres north of Kiandra. From its headwaters it flows to its confluence with the Murray River. The river flows for 66 km (41 mi) through the Australian Capital Territory near Canberra, picking up the important tributaries of the Molonglo and Cotter Rivers. The Murrumbidgee drains much of southern New South Wales and all of the Australian Capital Territory, and is an important source of irrigation water for the Riverina farming area.
The river system's current channels are relatively new with the Upper Murrumbidgee being an anabranch of the Tumut River (that once continued north along Mutta Mutta Creek) when geological uplift near Adaminaby diverted its flow. The contemporary Murrumbidgee starts at Gundagai but generally the stream that now includes the Upper Murrumbidgee is described as being part of the full river.
In June 2008 the Murray-Darling Basin Commission released a report on the condition of the Murray-Darling basin, with the Goulburn and Murrumbidgee Rivers rated in a very poor condition in the Murray-Darling basin with fish stocks in both rivers were also rated as extremely poor, with 13 of the 22 native fish species found in the Murrumbidgee River.
The Murrumbidgee River was known to Europeans before it was actually discovered by them. In 1820 the explorer Charles Throsby informed the Governor of New South Wales that he anticipated finding "a considerable river of salt water (except at very wet seasons), called by the natives Mur-rum-big-gee". In the expedition journal, Throsby wrote as a marginal note: "This river or stream is called by the natives Yeal-am-bid-gie ...". The river he had stumbled upon was in fact the Molonglo River, Throsby reached the actual river in April 1821.
In 1823, Brigade-Major John Ovens and Captain Mark Currie reached the upper Murrumbidgee when exploring south of Lake George. In 1829, Charles Sturt and his party rowed and sailed down the length of the river from Narrandera to the Murray, and then down the Murray to the sea. They also rowed, sailing when possible, back up against the current. The Murrumbidgee basin was opened to settlement in the 1830s and soon became an important farming area.
Here we may remark on the tenacity with which the Murrumbidgee River long eluded the eye of the white man. It is scarcely probable that Meehan and Hume, who on this occasion were within comparatively easy reach of the head waters, could have seen a new inland river at that time without mentioning the fact, but there is no record traceable anywhere as to the date of its discovery, or the name of its finder. When in 1823 Captain Currie and Major Ovens were led along its bank on to the beautiful Maneroo country by Joseph Wild, the stream was then familiar to the early settlers and called the Morumbidgee. Even in 1821, when Hume found the Yass Plains, almost on its bank, he makes no special mention of the river. From all this we may deduce the extremely probable fact that the position of the river was shown to some stockrider by a native, who also confided the aboriginal name, and so it gradually worked the knowledge of its identity into general belief. This theory is the more feasible as the river has retained its native name. If a white man of any known position had made the discovery, it would at once have received the name of some person holding official sway.
The river has risen above 7 metres (23 ft) at Gundagai nine times between 1852 and 2010, an average of just under once every eleven years. Since 1925, flooding has been minor with the exception of floods in 1974 and in December 2010, when the river rose to 10.2 metres (33 ft) at Gundagai. In the 1852 disaster, the river rose to just over 12.2 m (40 ft). The following year the river again rose to just over 12.5 m (41 ft). The construction of Burrinjuck Dam from 1907 has significantly reduced flooding but, despite the dam, there were major floods in 1925 and 1974.
In 1925, four people died and the flooding lasted for eight days.
The reduction in floods has consequences for wildlife, birds and trees. There has been a decline in bird populations and black box flood plain eucalypt forest trees are starting to lose their crowns.
Major wetlands along the Murrumbidgee or associated with the Murrumbidgee catchment include:
- Lowbidgee Floodplain, 2,000 square kilometres (772 sq mi) between Maude and Balranald
- Mid-Murrumbidgee Wetlands along the river from Narrandera to Carathool
- Fivebough and Tuckerbil Swamps
- Tomneys Plain
- Micalong Swamp

- Yaouk Swamp
- Black Swamp & Coopers Swamp
- Big Badja Swamp
- Gudgenby River
- Naas River (Naas flows into Gudgenby before Murrumbidgee despite what appears on the 1:100000 topographic map)
- Molonglo River
- Cotter River
- Tumut River
- Yass River
- Lachlan River
- Canberra particularly Tuggeranong
