Murray–Darling basin
The Murray–Darling Basin is a large geographical area in the interior of southeastern Australia, whose name is derived from its two major rivers, the Murray River and the Darling River. It drains around one-seventh of the Australian land mass,[1] and is one of the most significant agricultural areas in Australia. It spans most of the states of New South Wales, Victoria, and the Australian Capital Territory, and parts of the states of Queensland (lower third) and South Australia (south-east corner). It is 3,375 kilometres (2,097 mi) in length (the Murray River is 2,530 km (1,570 mi) long).
Most of the 1,061,469 km2 (409,835 sq mi) basin is flat, low-lying and far inland, and receives little direct rainfall. The many rivers it contains tend to be long and slow-flowing, and carry a volume of water that is large only by Australian standards.

Native fauna [edit]
The Murray Darling Basin is home for many native animal species. The true numbers are not known, but a fairly confident estimate has been made of these animals and the current status of their population. Among the aboriginal fauna in the region, the study found[citation needed] that there were:
- 80 species of mammals, with 20 extinct and 16 endangered.
- 53 species of frogs, with none endangered.
- 46 species of snakes, with 5 endangered.
- 5 species of tortoises, with none endangered
- 34 species of fish, with up to half either threatened or of conservation significance.[2]
Introduced species [edit]
The Basin has also played host to a variety of introduced species. One of the most well known is the carp. The timing of the introduction of carp into the system is not known.[3] By the 1920s the carp had become established in the Basin.
Four varieties of carp were used to stock up fish dams. Since then they have made their way into the river systems, where they spread quite quickly. Human introduction, possibly by anglers using carp illegally as live bait or stocking dams has also increased their distribution.[3] These fish are very mobile, as they can travel easily on flood waters and their eggs can be transported by birds.
These fish are a problem because they feed by sucking gravel from the river bed and taking all the edible material off it, before returning the rest to the water. This stirs up all the sediment, reducing the quality of the water. When caught by a fisherman, it must be killed by law.
Physiography [edit]
This area is one of the physiographic provinces of the larger East Australian Basins division, and encompasses the smaller Naracoorte Platform and Encounter Shelf physiographic sections. Total water flow in the Murray–Darling basin 1885 to the present has averaged around 24,000 gigalitres per year. This is the lowest rate of the world's major river systems.[1] About 6% of Australia's total rainwater falls into the basin.[4] In most years only half of this quantity reaches the sea and in dry years much less. Estimated total annual flows for the basin have ranged from 5,000 gigalitres in 1902 to 57,000 gigalitres in 1956[citation needed]. Despite the magnitude of the basin, the hydrology of the streams within it is quite varied.
These waters are divided into four types:[5]
- The Darling and Lachlan basins. These have extremely variable flows from year to year, with the smallest annual flow being typically as little as 1 percent of the long-term mean and the largest often more than ten times the mean. Periods of zero flow in most rivers can extend to months and in the drier parts (Warrego, Paroo and Lower Darling basins) to years.[5] Flows in these rivers are not strongly seasonal. In the northern regions the majority of floods occur in the summer from monsoonal penetration. For most of the Darling and Lachlan catchments it is typical to see high or low flows begin in winter and extend to the following autumn (see El Niño). High water extraction rates for irrigation and mining have heavily compromised these rivers.
- The south-western basins (Campaspe, Loddon, Avoca, Wimmera). These have a marked winter rainfall maximum and relatively lower precipitation variability than the Lachlan or Darling. However, the age and infertility of the soils mean that run-off ratios are exceedingly low (for comparison, around a tenth that of a European or North American catchment with a similar climate[6]). Thus, variability of runoff is very high and most of the terminal lakes found in these basins very frequently dry up. Almost all runoff occurs in the winter and spring and, in the absence of large dams for regulation, these rivers are often seasonally dry during summer and autumn.
- A number of small catchments in South Australia, of which the largest are the Angas River flowing through Strathalbyn and the Finniss River further west, are part of the Murray–Darling Basin. These catchments lead to Lake Alexandrina, one of the lakes at the end of the Murray system. The Angas River is often dry in summer because of high levels of water extraction. The Finniss River has permanent flow which previously went into Lake Alexandrina but now has been cut off by a weir. The Finniss now fills the Goolwa Channel for recreational boating.
- The Murrumbidgee, Murray and Goulburn basins (except the Broken River which resembles the south-western basins). Because these catchments have headwaters in alpine country with relatively young peaty soils, the runoff ratios are much higher than in other parts of the basin. Consequently, although gross precipitation variability is no lower than in the Lachlan or Darling basins, runoff variability is markedly lower than in other parts of the basin. Typically these rivers never cease to flow and the smallest annual flow is typically around 30 percent of the long-term mean and the largest around three times the mean. In most cases the flow peaks very strongly with the spring snow melt and troughs in mid-autumn.
Of the approximately 13,000 gigalitres of flow in the basin, which studies have shown to be divertible, 11,500 gigalitres are removed for irrigation, industrial use, and domestic supply. Agricultural irrigation accounts for about 95% of the water removed,[1] including for the growing of rice and cotton. This extraction is highly controversial among scientists in Australia, regarding the agriculture industry's high water use in a region extremely short of water (as much due to exceptionally low run-off coefficients as to low rainfall).[7]
Rivers in the Murray–Darling Basin [edit]
The rivers listed below comprise the Murray–Darling basin and its direct significant tributaries, with elevations of their confluence with the downstream river. The tributary with the highest elevation is Swampy Plain River that rises in the Snowy Mountains, below Mount Kosciuszko at an elevation of 2,120 metres (6,960 ft), and ends merging with the Murray River, descending 1,860 metres (6,100 ft).

Management [edit]
The basin covers five states and territory governments, who according to the Constitution, are responsible for managing water resources. The River Murray Commission was established in 1917.[1] Under the River Murray Waters Agreement, which never included Queensland despite the state containing about a quarter of the basin, the Commission's role was only as an advisory body with no authority for the enforcement of provisions. For a long time the Commission was only concerned with water quantity until salinity became a problem. This led to minor reforms in 1982 in which water quality became part of the Commission's responsibilities.[1] However, it was soon recognised that a new organisational structure which considered the national perspective was needed for effective management.
The Murray–Darling Basin Agreement was first adopted in 1985 but it wasn't until 1993 that its full legal status was in-acted.[1] The Agreement led to the creation of a number of new organisations under what is known as the Murray-Darling Basin Initiative. These included the Murray-Darling Basin Ministerial Council and the Murray Darling Basin Commission.
The Murray–Darling Basin plan [edit]
The Murray-Darling Basin Plan was signed off by Tony Burke, Minister for Sustainability, Environment, Water, Population and Communities on 22 November 2012, and passed its final hurdle in the Australian Parliament on the 29 November 2012. Following is the history leading up to this significant occasion in the history of Australian water reform.
In October 2010, The Murray–Darling Basin Authority released a draft plan to secure the long-term ecological health of the Murray–Darling Basin. This entailed cutting existing water allocations and increasing environmental flows.[8] The document is officially titled the Guide to the Proposed Murray–Darling Basin Plan. It is the first part of a three-stage process to address the problems of the Murray–Darling Basin.[9] MDBA is responsible for preparing and overseeing a legally-enforceable management plan — the Basin Plan.
The Basin Plan is designed to set environmentally sustainable limits on the quantities of water that may be taken from Basin water resources, to set Basin-wide environmental, water quality and salinity objectives, to develop efficient water trading regimes across the Basin, to set requirements for state water resource plans and to improve water security for all Basin users.[10] It also intends to minimise social and economic impacts whilst achieving the plan's environmental outcomes.[11]
With the release of the Guide to the Proposed Murray–Darling Basin Plan there have been a number of protests and voiced concerns about the plan in rural towns that the MDBA visited to present the plan to consultation meetings.[12] More than 5,000 people attended a MDBA meeting in Griffith where Griffith Mayor, Mike Neville, said the plan would "obliterate" Murrumbidgee valley communities.[13] Other groups also echo this feeling, such as the Victorian Farmers Federation[14] and Wine Group Growers' Australia.[15] Conversely, support for the Murray–Darling Basin plan has been received by various groups, including Australian Conservation Foundation,[16] and Environment Victoria.[17]
New legal advice from lawyers for the Federal Government is changing the plan. The Government's reading is that the plan must give equal weight to the environmental, social and economic impacts of proposed cuts to irrigation. Environmentalists and South Australian irrigators, at the end of the river in South Australia, say the authority should stick to its original figure.[18]
In October 2010, a parliamentary inquiry into the economic impacts of the plan was announced.[19]
In late October 2010 the Water Minister, Tony Burke, played down the prospect of a High Court challenge to the Murray–Darling Basin plan, as confusion continued over new legal advice released by the Government. In response to community concerns that the Murray–Darling Basin Authority had put environmental issues first over social and economic needs, Burke released new advice on the requirements of the Water Act. Burke stated that the Act does allow for the authority to 'optimise' the needs of all three areas, but constitutional lawyer, George Williams, had cast doubts over the interpretation of the laws, stating it could be subject to a legal challenge.[20]
The MDBA announced in November 2010 that it might be forced to push back the release of its final plan for the river system until early 2012.[21]
The then MDBA chairman, Mike Taylor, reassured the public meeting that more work is being done to look at how the proposed cuts would affect regional communities. He stated; "Importantly, we want to make sure the social and economic impacts—which under any sort of scenario is very significant—were fully teased out".[22] Taylor resigned as he allegedly believed that the overriding principle should be the environmental outcome which was in conflict with the Gillard Government and following a period of sustained criticism of the Authority and the implementation of the proposed draft basin plan.[23] He was replaced by former New South Wales Planning Minister, Craig Knowles.[24][25][26]
In late May 2012, the revised plan was forwarded to state water ministers.[27] It did not alter the recommendation to cut 2,750 gigalitres of water entitlements.
Following much negotiation between the Commonwealth and State governments and numerous submissions from interested stakeholders and the community,the Basin Plan finally became law in November 2012 and can now be implemented. Sustainability Although the MDBPG is a positive step towards sustainability the policy cannot be considered sustainable due to the conservative level of water that is being allocated for the environment. The Environmental Water Requirement found that 7600gl per year is required to be certain that the river systems would maintain their health. However due to fear of socio economic impacts on local communities such as … (Eg less jbs, reduction in land price) only 3000-4000gl/y allocation is being considered. This was also due to strong opposition of the policy by the Victorian farmers federation. For this policy to be considered sustainable the MDBA should have been willing to compromise the short term economic losses of the irrigators and in order to allow a larger allocation of water for environmental flows by going forward with the 7600GL/y allocation. In order to preserve the health of the river systems within the murray darling system for the future, these environmental flows are nessesart. Without healthy river systems economic and social impacts will occur in the future. Such as a less stable economy and additional stress on our ability to feed our growing population. Both a result of reduced water security due to the policies that do not support the needs of the environment for sustainablitiy specifically the MDBPG
