Murray–Darling Basin

Water rights, entitlements, allocations and trade

The National Water Account 2010 acknowledges the varying jurisdictional legislative water resource management frameworks related to Australian rights to water that support water resource management in Australia. The jurisdictional legislative water resource management frameworks vary greatly between jurisdictions, sometimes making comparisons difficult. To facilitate meaningful comparison between the water accounting reports included in the National Water Account 2010, the Bureau of Meteorology has developed and applied an accounting concept to classify and report water entitlements within a water-asset/water-liability framework. The accounting concepts for ‘regulated’ and ‘unregulated’ may differ from the legislative interpretation in some jurisdictions.

The application of the 2010 Account water accounting conceptual framework of regulated and unregulated to the entitlements and claims to water in the Murray–Darling Basin (MDB) region results in the classification and reporting of water rights, allocations and abstraction in the 2010 Account as detailed in the table in the following page for the 2009–10 reporting period. Details of the information presented in the table are provided in the subsequent pages. The following jurisdiction-specific characteristics apply to the information presented in the table:

In Queensland – entitlement giving access to unregulated (unsupplemented) flows may report either of these values:
- The ‘volumetric limit’: the maximum volume of water that can be extracted over a given period, or
- The ‘nominal volume’: for water allocations with flow conditions, the nominal volume approximates the long-term annual average volume of water that the entitlement is expected to give access to (under the run of the model).
In Queensland – entitlement giving access to regulated (supplemented) flows may report the ‘nominal volume’, against which allocations are announced.
In New South Wales – entitlements giving access to unregulated flows may report the ‘entitled volume’, which specifies an upper limit to the volume of water that can be extracted over a given period:
- In case the entitlement exists within a water sharing plan (commenced or in draft), defined under the Water Act 2000, that period is 12 months.
- In case the entitlement exists within an area that is still under theWater Act 1912, and consequently has no Water Sharing Plan, that period can be 12 months or several years. The actual duration of the period is unspecified in the table, as the data source used was the water audit monitoring (WAM), which did not contain this information.
In New South Wales – entitlement giving access to regulated flows may report the ‘entitled volume’, against which allocations are announced.
In Victoria – entitlements giving access to unregulated flows may report the ‘entitled volume’, which specifies an upper limit to the volume of water that can be extracted over a 12-month period.
In Victoria – entitlement giving access to regulated flows may report the ‘entitled volume’, against which allocations are announced.
In South Australia – all entitlements have been classified as giving access to regulated flow and may report the ‘entitled volume’, against which allocations are announced.

The table above provides information about New South Wales, Queensland and Victoria. Information about surface water unregulated flows urban class rights in other states:

Australian Capital Territory – no information available to be reported in this account.
South Australia – all water has been treated as regulated, see ‘Water access entitlements from regulated flows – high-security class: R1.3.2.4 Urban holder’ for information about urban class in South Australia.

Water allocations

No information available to be reported in this account. In unregulated systems the availability of urban water is subject to minimum passing flow requirements and the volumes in local weirs or town dams. Allocations are not normally made.

Water restrictions

For Victoria, due to minimal inflows and low storage volumes, restrictions were applied to this class of entitlement during the reporting period. All Victorian towns are subject to a uniform scale of water restrictions under the Victorian Uniform Drought Water Restriction Guidelines, which provide for four restriction stages. Water businesses may grant exemptions from water restrictions. Each urban water business also has a permanent water savings plan that applies at all times. These plans set basic conditions around water use when water restrictions are not in place.

For Queensland, no restrictions are known for this entitlement category.

Quantification approach

Approximations, assumptions, caveats/limitations

Some of the volumes reported under this entitlement category may actually relate to other purpose than irrigation (e.g. urban purpose in Paroo): see the breakdown table in ‘Supporting information’.

When water management plans have been used as data sources, the entitlement volumes reported are the volumes at the commencement of the water plans. The actual volumes of entitlements for a given class on issue during the reporting period may be different from the volumes at the commencement of the water plan, due to conversions between classes or issue of new entitlements. Note that trade (ownership transfer), water savings projects or buy back of entitlements for environmental purpose do not change the volume entitled within a class but only its ownership.

Water access entitlements from unregulated flows: R1.2.5.6 Other lumped holders (environment)

Supporting information

The volumes reported in the table below are a subset of R1.2.5.6 Water access entitlement on unregulated flows – other lumped holder.

Included in this category are entitlements in both regulated and unregulated systems that give access to unregulated flows (e.g. unsupplemented water allocations in Queensland or supplementary water access in regulated rivers in New South Wales).

Data provider

Murray–Darling Basin Authority.

Method

The volumes were extracted from Murray–Darling Basin Environmental Water Recovery Report.

Uncertainty

Ungraded.

Approximations, assumptions, caveats/limitations

Entitlement volumes shown reflect only those that have been recorded as being legally held (or under the administrative operations of the environmental water manager) as at 30 June 2010 to provide a benefit for the environment. The volumes will be subject to change as water is continually acquired under some programs. In particular, the volumes held by Commonwealth Environmental Water Holder (CEWH) will increase as more licences are acquired. These volumes do not reflect the progress with water recoveries as some transactions are yet to be settled at the reporting date.

For Queensland, volumetric limit, which is higher than the nominal volume, has been reported as the entitlement value for majority of the regions in the above table.

The table above provides information about New South Wales, Queensland and Victoria. Information about surface water unregulated flows other lumped holders rights in other states:

Australian Capital Territory – no information available to be reported in this account.
South Australia – all water has been treated as regulated, as unregulated licences do not exist except for in the Marne Saunders Prescribed Water Resource Area.

Included in the category are entitlements in both regulated and unregulated systems, and are unregulated flows (e.g. unsupplemented water allocations in Queensland or supplementary water access in regulated rivers in New South Wales).

Where the purpose of the licence could not be distinguished, it was included in this class. Although many licences can be assumed to be used for irrigation, they may also include some urban, commercial or industrial uses.

Water allocations

No information available to be reported in this account. In unregulated systems the availability of other lumped holders’ water is subject to minimum flow requirements and conditions on licences. Allocations are not normally made. In regulated systems the availability of other lumped holders’ water may be subject to announcements during the year that an event has occurred and water will be available for a period of time or until flows recede.

Water restrictions

In general, licence conditions (e.g. specific flow conditions to trigger availability) limit the ability to access water. For Victorian unregulated licences, rostering and restrictions were applied during 2009–10 (source: Annual Report 2009–10 for Goulburn–Murray Water).

Quantification approach

Data source

Approximations, assumptions, caveats/limitations

When water management plans have been used as data sources, the entitlements’ volumes reported are the initial volumes of the water plans. The actual volumes of entitlements for a given class on issue during the reporting period may be different from the initial volumes on issue at the time of the water plans’ commencement, due to conversions between classes or issue of new entitlements. Note that trade (ownership transfer), water savings projects or buy back of entitlements for environmental purpose do not change the volume entitled within a class but only its ownership.

The following table gives the percentage of allocations announced on the various Basin Plan regions.

Note that the actual volume of allocations announced reported (in Line item 25.1.2.4) for a given entitlement may be different from the product of the entitled volume reported by the percentage of allocation announced. Several reasons can explain this difference:

the percentage of allocations announced and the actual allocated volumes may be given for different water plan areas within a same region

the actual volumes of entitlements for a given class on issue during the reporting period may be different from the initial volumes on issue at the time of the water plans’ commencement, due to conversions between classes, issue of new entitlements or cancellations of existing entitlement.

The table above provides information about New South Wales and Victoria. These two states are the only states to have this class of water ‘general security’ in New South Wales and ‘low reliability’ in Victoria.

Information about surface water regulated flows general/low security class in other states:

Australian Capital Territory – no information available to be reported in this account. No such class applies in the Australian Capital Territory.
Queensland – no information available to be reported in this account. No such class applies in Queensland.
South Australia – no information available to be reported in this account. No such class applies in South Australia.

For those states (Australian Capital Territory, Queensland and South Australia), regulated flows are reported under other entitlement categories: R1.3.4 (urban class) or R 1.3.9.2 (Other – lumped class – Individual irrigator holder)

Water allocations and restrictions

See Line item 25.1.3.6 in the water accounting statement note for allocations.

The following table gives the percentage of allocations announced on the various Basin Plan regions.

Note that the actual volume of allocations announced reported (in Line item 25.1.3.6) for a given entitlement may be different from the product of the entitled volume reported by the percentage of allocation announced. Several reasons can explain this difference:

the percentage of allocations announced and the actual allocated volumes may be given for different water plan areas within a same region
the actual volumes of entitlements for a given class on issue during the reporting period may be different from the initial volumes on issue at the time of the Water Plans’ commencement, due to conversions between classes, issue of new entitlements or cancellations of existing entitlement.

The table above provides information about Australian Capital Territory, New South Wales, Queensland, South Australia and Victoria. Where it is clear that the purpose of the entitlement is for urban use in regulated systems, it has been classified in this entitlement category. Where the water is used for urban purposes and is an unregulated system, the volume has been recorded in ‘Water access entitlements from unregulated flows: R1.2.2 Urban class’. In some regions it was not clear whether there is an urban purpose, therefore this entitlement category may not include all urban uses.

1. Includes Nebine catchment in addition to Condamine–Balonne catchment. This includes some entitlement volumes that are for unsupplemented areas but were not able to be separated. Allocation percentage varies depending upon the priority and stretch of river. Allocations in the Upper Condamine (Cecil Plains Weir) were 70% at 1 July 2009, increased to 94% on 1 August 2009 then to 100% on 1 February 2010. The Chinchilla Weir Water Supply Scheme and Maranoa River Water Supply Scheme had an allocation of 100%. As the St George Water Supply Scheme is predominantly a capacity share scheme and does not have an annual announced allocation, the effective percentage was 100%.
2. Includes some entitlement volumes that are for unsupplemented areas but were not able to be separated. As the Border Rivers Water Supply Scheme is a continuous accounting scheme and does not have an annual announced allocation, the effective allocation was 24%. As part of the Macintyre Brook Water Supply Scheme is subject to announced allocation and is gradually moving to continuous accounting, the effective allocation was 72% in 2009–10.

The table above provides information about New South Wales, which is the only state within the Murray–Darling Basin that has this class of entitlement. The volumes shown here represent volumes for conveyance losses in the regulated Murray River and the volumes held by Irrigation Trust for the conveyance of irrigation water to members. As these water entitlements receive allocations and as usage volumes (abstractions) are recorded against them, they have been included in this report.

The bulk entitlements in Victoria have a similar concept that provides for losses within the distribution of irrigation licences. However, as these do not record an allocation or a usage, they have not been included within this report.

The actual volumes held by the irrigators within the irrigation areas stated in the above table are recorded in:

Water access entitlements from regulated flows – high-security class: R1.3.2.7 other lumped holders
Water access entitlements from regulated flows – general or low-security class: R1.3.3.6 other lumped holders.

Water allocations and restrictions

See Line item 25.1.9.1 in the water accounting statement notes for allocations. The following table gives the percentage of allocations announced on the various Basin Plan regions.

the percentage of allocations announced and the actual allocated volumes may be given for different water plan areas within a same region
the actual volumes of entitlements for a given class on issue during the reporting period may be different from the initial volumes on issue at the time of the Water Plans’ commencement, due to transfer or conversions between classes, issue of new entitlements, cancellations' of licences resulting from water savings projects or buy back of entitlements for environmental purpose.

– = no data available

The table above provides information about Queensland and South Australia. The volumes shown here represent the volumes in regulated systems where the purpose is clearly for irrigation. In most regions licences are issued for a class not a purpose, unless specifically for urban or environmental use. Although it may be assumed that licences are used for irrigation, they may also be traded and used for commercial, industrial, environmental or urban purposes. Information is not available about the final use of the traded water. Therefore, most regions have been assessed as ‘other lumped holders’ purpose rather than describing them as ‘irrigation’, even though that may still be the dominant purpose.

Water allocations and restrictions

See Line item 25.1.9.2 in the water accounting statement notes for allocations.

The following table gives the percentage of allocations announced on the various Basin Plan regions.

Note that the actual volume of allocations announced reported (in Line item 25.1.9.2) for a given entitlement may be different from the product of the entitled volume reported by the percentage of allocation announced. Several reasons can explain this difference:

the percentage of allocations announced and the actual allocated volumes may be given for different water plan areas within a same region
the actual volumes of entitlements for a given class on issue during the reporting period may be different from the initial volumes on issue at the time of the Water Plans’ commencement, due to transfer or conversions between classes, issue of new entitlements, cancellations' of licences resulting from water savings projects or buy back of entitlements for environmental purpose.


Region no.	Region name	Entitlement class	State	Allocation (%)
2.1	Warrego – Qld	Supplemented Water Allocations	Qld	100%
3.1	Condamine–Balonne – Qld	Supplemented Water Allocations	Qld	See Note 1

18.3	Murray – SA		SA	62%
18.3.a	Murray – SA	Non-swamp irrigation	SA	62%
18.3.b	Murray – SA	Swamp irrigation	SA	62%

Notes

Includes Nebine catchment in addition to Condamine–Balonne catchment. Allocation percentage varies depending upon the priority and stretch of river

The Upper Condamine Water Supply Scheme had an announced allocation from Leslie Dam of 0%; however, the % allocation has been adjusted to reflect water permitted to be taken under stream flow period rules, this was equal to 70%. The Chinchilla Weir Water Supply Scheme and Maranoa River Water Supply Scheme had an allocation of 100%. The St George Water Supply Scheme is predominantly a capacity share scheme and doesn't have an annual announced allocation, the effective percentage was 100% for 2009–10.
The Border Rivers Water Supply Scheme is a continuous accounting scheme and doesn't have an annual announced allocation, the effective allocation was 24%. Part of the Macintyre Brook Water Supply Scheme is subject to announced allocation and is gradually moving to continuous sharing, the effective allocation was 72% for 2009–10.

– = no data available

The above table provides information about New South Wales.

Information about groundwater basic rights in other states:

Australian Capital Territory – no groundwater management units from Australian Capital Territory are being reported in this account.
Victoria – in addition to licensed groundwater entitlements in Victoria there is a 'domestic and stock' groundwater entitlement. This is associated with an approval to construct a bore and there is no formal volumes assigned to these entitlements. All Victorian groundwater basic rights are included in ‘Groundwater entitlement: R2.2.3.7 Other lumped holders’.
Queensland and South Australia – no information available to be reported in this right category.

Water allocations

Groundwater basic rights do not generally have an allocation announcement. The maximum groundwater volume that can be extracted each year is up to the licensed entitlement volume. Where no formal licence exists, the volume that may be extracted is limited and restricted to purposes such as domestic and stock use. This is similar in concept to surface water riparian rights.

Water restrictions

No restrictions known for this right category.

The table above provides information about New South Wales and Victoria. Information about groundwater entitlements not able to be separately classified in other states are:

Australian Capital Territory – no groundwater management units from the Australian Capital Territory are being reported in this account.
Queensland – no information available to be reported.
South Australia – groundwater rights are described as hectare irrigation equivalents (haIEs); no information available about volumetric rights.
Vic–SA border – The Victoria – South Australia Border Groundwaters Agreement is supported by legislation in both states. It provides for equitable sharing in the border zone, which extends from the coast to the Murray and is a 40-km wide zone centred on the border. The states agree on setting permissible consumptive volumes, etc within this zone. Various alluviums selected for reporting are either within or partly within this border zone. These are the Murrayville Water Sharing Plan Area (WSPA), Kaniva TCSA and Telopia Downs WSPA in Victoria, and Mallee Prescribed Water Area (PWA) and Tintinara-Coonalpyn PWA in SA. These are state groundwater management units and licensed entitlements, and extractions are included within the state groundwater management unit – not within the border zone. Therefore, separate reporting on the border zone is not needed and would be double-counting.
The Tintinara–Coonalpyn PWA is not included as part of this region. It is not considered to be part of the MDB resources and is excluded from the MDB by Water Act regulations.

Data Source

When water management plans have been used as data sources, the entitlement volumes reported are the initial volumes of the water plans. The actual volumes of entitlements for a given class on issue during the reporting period may be different from the initial volumes on issue at the time of the water plans’ commencement, due to conversions between classes or issue of new entitlements. Note that trade (ownership transfer), water savings projects or buy back of entitlements for environmental purpose do not change the volume entitled within a class but only its ownership.

R3.1 Run-off harvesting entitlement

Supporting information

Entitlement volumes were not available for inclusion in the accounting statements. Following is an explanation of the different terms used within the Murray–Darling Basin and how each jurisdiction manages run-off that may be taken from the land, thus preventing it from reaching a watercourse.

Queensland

Queensland uses the term ’overland flow’. Overland flow is water that runs across the land after rainfall, either before it enters a watercourse, after it leaves a watercourse as floodwater, or after it rises to the surface naturally from underground. Most water in rivers and underground reserves originates as overland flow. If too much water is intercepted before it reaches a watercourse, or if too much floodwater is intercepted before it returns to a watercourse, there can be serious implications for:

towns, industries and farms that rely on watercourses for water supplies
landholders who rely on beneficial flooding
the maintenance of healthy waterways
groundwater recharge
ecosystems relying on periodic inundation.

A person may take overland flow for any purpose unless there is a moratorium notice, a water resource plan or wild river declaration that limits or alters the water that may be taken. Rules in water resource plans established under the Water Act 2000 (Qld) regulate the building of works that take overland flow either actively or passively.

Works that take it actively include:

pumps, storages, sumps, drains and pipes used to take and store it
any storage connected to another one used to take it, and the connecting infrastructure
structures used to hold it for ponded pastures.

Works that take it passively include:

levees or diversion banks used to direct it into dams, or to slow it down to increase the amount taken. This does not include works used in soil conservation.

Water resource plans do not regulate works that ‘interfere’ with, but were not built specifically to take overland flow. However, local planning laws may still regulate the building of these structures, which include contour banks, fences and roads.

Where the construction of overland flow works is regulated, the development may be either assessable or self-assessable development under the Sustainable Planning Act 2009 (Qld). See Codes for assessable and self-assessable development for information on constructing works for taking overland flow.

Currently, the taking of overland flow is regulated in the following water resource plan areas:

In all of these areas, it is required to have:

an authorisation to take overland flow
a development permit under the Sustainable Planning Act 2009 (Qld) for most works for taking overland flow.

New South Wales

Landholders in most New South Wales rural areas are allowed to collect a proportion of the rainfall run-off on their property and store it in one or more dams up to a certain size. This is known as a 'harvestable right'. Harvestable right water is generally intended for essential stock and household use but can be used for any purpose.

All rural landholders in New South Wales are able to maintain or build farm dams. There are several categories of farm dams that do not require a licence:

harvestable right dams
dams built before 1999 used only for stock and domestic purposes
dams up to one megalitre on small properties.

In addition to rainfall run-off harvesting, New South Wales has addressed floodplain harvesting. Floodplain harvesting is the collection, extraction or impoundment of water flowing across floodplains.

Harvesting of on-farm rainfall run-off is not included within the definition of floodplain harvesting. However, because rainfall run-off can be harvested by the same infrastructure as floodplain extractions, it is important to specify the regulatory distinction between the two types of water extraction. All rainfall run-off harvesting must be in accordance with the Harvestable Rights Order by which the area is constituted as provided for under Chapter 3, Part 1, Division 2 of the Water Management Act 2000 (NSW). Within most of New South Wales, the allowable maximum harvestable right is currently 10% of average annual run-off. The run-off is primarily a function of rainfall, evaporation, soil type, topography and vegetation cover. The allowable run-off harvesting volume is converted to a Maximum Harvestable Right Dam Capacity, using a publicly available, web-based calculator. The allowable harvestable right volume of run-off will be assumed to have been taken and will be factored into the assessment of floodplain harvesting extractions.

In April 2010, the New South Wales Government issued the draft NSW Floodplain Harvesting Policy. The draft policy outlines how floodplain harvesting extractions will be managed within long-term average annual extraction limits under water sharing plans and the Murray–Darling Basin Ministerial Council Cap where applicable. There will be no growth in overall extractions on a valley-wide basis as a result of the implementation of this policy. All floodplain harvesting activities will require a water supply work approval and a floodplain harvesting water access licence issued under the Water Management Act 2000 (NSW).

Australian Capital Territory

The Australian Capital Territory Government’s Think Water Act Water strategy for sustainable water resource management in the ACT, outlines actions the ACT Government plans to improve management of stormwater run-off, including adopting water sensitive urban design principles.

Victoria

The Northern Region Sustainable Water Strategy (Chapter 2) discusses the impacts of interception activities. Interception activities are a risk to water availability because they capture rainfall before it becomes surface run-off or groundwater recharge. These activities include small catchment dams (for farms or domestic and stock use), changes in land use and the impact of forest regeneration due to bushfires. These activities have not historically required a water entitlement (except for small catchment dams for irrigation or commercial purposes, which have required a licence since 2002). However, they can reduce the amount of water available to downstream entitlement holders and the environment.

Unlike dams for commercial and irrigation use, dams for domestic and stock use are not licensed and therefore can continue to be built without scrutiny of their impact on downstream users and the environment. Based on current estimates, unlicensed dams capture six per cent of the available surface water in northern Victoria. At a local level, the impact of unlicensed dams can be even greater.

Several actions have been listed in Chapter 4 of the Northern Region Sustainable Water Strategy to manage the impacts of stock and domestic use. Some key actions will be:

requiring the registration of all new or altered domestic and stock dams within rural residential areas and promoting sustainable use in accordance with guidelines for reasonable domestic and stock use
monitoring growth in domestic and stock use
clarifying the need to obtain a Section 51 licence for harvesting water for uses other than domestic and stock purposes.

South Australia

The South Australia Government’s Water for Good strategy identifies a number of projects to increase the volume of water collected from stormwater harvesting, both within Adelaide and in rural South Australia. These projects involve storing and treating stormwater in wetlands and aquifers.

R4.1 Interbasin agreement to transfer water in

Supporting information

See Line item 7.1 in the water accounting statement notes for details.

The value reported for the agreement category includes only the claim, at 30 June 2010, to have water transferred into the MDB from the Snowy Hydro Scheme (see note of Line item 7.1 for detailed information).

Water transfer from the Glenelg River Catchment to the Wimmera–Mallee supply system, made by Grampians Wimmera–Mallee Water under a Victorian bulk entitlement (see note of Line item 13.6.3) is also considered in this agreement category. However, information on this transfer is not included in Line Item 7.1 because there is no claim remaining at the end of the year.

The following water transfers into the MDB are not reported in this agreement category, because they are made not by the reporting region but rather by water distribution systems that are not part of the region:

Water transfers from Cressbrook and Perseverance reservoirs on Cressbrook Creek in South East Queensland region, made by Toowoomba Regional Council under an entitlement it holds within the Moreton Water Resource Plan Area (see note of Line item 13.6.3).

Quantification approach

See Line item 7.1 in the water accounting statement note.

R4.2 Interbasin agreement to transfer water out

Supporting information

The water transfers occurring out of the Murray–Darling Basin (MDB) are not made under interbasin agreements, but rather under water entitlements held by organisations outside the MDB:

Water transfers from the Goulburn–Broken region to Sugarloaf Reservoir in Melbourne region, via the North–South Pipeline. On 27 January 2010, the Melbourne retail water businesses received bulk entitlements for their share of water savings from the Northern Victoria Irrigation Renewal Project. The retailers’ bulk entitlements were disallowed by the Victorian Legislative Council on 25 June 2010. Between 26 and 30 June, water was supplied to the retailers under a supply agreement with Goulburn–Murray Water.
Water transfers from the Goulburn–Broken region to Ballarat (in the Barwon River Basin) via ‘Goldfields Superpipe’ since May 2008.
Water transfers from the Goulburn–Broken region (from Silver and Wallaby creeks which are tributaries of the Goulburn River) to the Melbourne urban supply system (see Line item 14.6.2 in the water accounting statement notes).
Water transfers from the River Murray in South Australia to the storages in Adelaide region for urban purpose are made under a water entitlement (River Murray Licence) held by SA Water (see Line item 13.6.3 in the water accounting statement notes). Water transfers also occur to country towns such as Whyalla.

Quantification approach

Water market activity

Scope and structure of information reported

Only surface water trade is reported for the Murray–Darling Basin (MDB) region during 2009–10. Groundwater trade is not reported as there was limited information in relation to groundwater trade (at the data collection period for the 2010 Account) within the region during 2009–10.

During the 2009–10 reporting period, no water was traded across the boundaries of the MDB region.

Because all water trades occurred within the boundaries of the MDB region, they did not increase or decrease the water asset and water liabilities of the MDB region as a whole. Therefore, water trade is not reported in the National Water Account 2010 water accounting statements.

Nevertheless, water trades between different Basin Plan regions of the MDB had a significant impact on the allocations announced, diverted, forfeited and carried-over under specific classes of water access entitlements over the whole MDB region, as illustrated in the example below:

An allocation is announced in the source valley of the trade against an entitlement – of a certain class – held by the future seller of the allocation.
The allocation is sold to another entitlement holder in the destination valley of the trade. When the trade is completed, the volume traded will be added to the allocation account of the buyer.
The allocation account of the buyer may relate to another entitlement class than the one under which the seller had the original allocation announced: hence an allocation announced under a given entitlement class may be reported as being diverted, forfeited and carried over under another class.

The following information on water trades is reported in detail further down:

approved permanent trade of surface water entitlements
approved trade of surface water allocations
impact of Inter-Valley Trade on regions’ water assets and liabilities.

No information on lease of water access entitlement is reported because of lack of sufficient information. It is noted that some lease arrangements would be reported as allocation trade.

Permanent entitlement trade of surface water

The table below reports on the volume of permanent trades approved during 2009–10 in the MDB region and not on the volumes of water physically delivered. During this period, permanent entitlement trade only occurred in regulated systems. There was no trade in the unregulated systems within the Murray–Darling Basin region.

During 2009–10, tagging of entitlements, resulting from permanent entitlement trade into and out of Basin Plan regions occurred, but it was very small in volume compared to allocation trade and the tagged trades have not been reconciled across states (see National Water Commission Australian Water Markets Report 2009–10, p. 29 Table 3.2). The table below does not include information on tagged trade (into or out of Basin Plan regions) due to lack of necessary data.

Method

WAM-supplied data are obtained from water trade registers.

Uncertainty

WAM-sourced data do not have any uncertainty information on entitlement permanent trade.

Assumptions, approximations, caveats/limitations

It is assumed that all trade is occurring within regions that are predominantly regulated or supplemented. Where volumes are reported in a region that is both regulated (supplemented) and unregulated (unsupplemented), it is assumed that the trade occurred in the regulated (supplemented) systems of the region only.

Allocation trade of surface water

Surface water allocation trade occurred in regulated surface water systems, within and between the Basin Plan regions during 2009–10 and is reported in the table below, which reports on the volume of allocation trades approved during 2009–10 and not on the physical volumes of water physically delivered. During this period, allocation trade was only possible in the regulated systems and not in the unregulated systems.

– = no data available

In the above table, the volume of water allocations reported as being traded into the Basin Plan regions did not equate the volume of water allocations traded out of the Basin Plan regions as it logically should. This could have occurred for the following reasons:

state reporting of actual trades can differ if a trade is approved and then cancelled
differences in the recording the volume of water traded and approved between the originating region and the destination region of the water trade. This may result if an exchange rate or a transmission loss is applied against the original volume of water traded in the originating state versus the state of destination for the water trade
the timing differences, as to when the trade was actually approved in each of the states or regions.

For these reasons, the inter-state reconciliation of trade is an important part of confirming total trade.

Impact of inter-valley trade on regions’ water assets and liabilities

Water traded into or out of valleys (or regions) impacts on their water assets and water liabilities in several ways including:

• creation of claims and obligations between valleys

• transfer of the obligation to deliver allocated water to the water users.

Claims (water assets) and obligations (water liabilities) between valleys

Schematically, in the case of trade into a valley:

when the trade transaction is approved, there is the creation of a claim (non-physical water asset) in the destination valley of the trade (i.e. where the purchaser is registered), against the source valley (i.e. where the seller is registered)
delivery obligation is moved from the selling valley to buying valley
when water is physically transferred to the destination valley, it decreases its claim (non-physical water asset) against the source valley.

In the case of trade out of a valley, the reverse occurs:

when the trade transaction is approved, an obligation (water liability) in the source valley of the trade towards the destination valley is created
when water is physically transferred out of the source valley, its obligation (water liability) towards the destination valley is decreased.

Note that in both cases the inter-valley transfer may occur in a subsequent water year to the year to when the trade was approved, the inter-valley transfer may be cancelled by back-trade or the inter-valley transfer account may spill which cancels the obligation to the destination valley.

For instance, water traded to South Australia up to 31 March in a water year is delivered from September to April in that water year in the same pattern of delivery as the remaining South Australian monthly diversion entitlements over that period. Water traded from 01 April to 31 August is delivered over the following September to April.

The table below shows the opening (01 July 2009) and closing (30 June 2010) balances on the inter-valley trade accounts in the southern connected Murray–Darling Basin for the 2009–10 year, as well as their net movements during the 2009–10 year. Inter-Valley Trade (IVT) account is the amount available to be called upon and delivered into the destination valley.

Inter-valley trade account balances in the southern connected Murray–Darling Basin – Volumes (ML)
Inter-valley trade (IVT) account	Balance at 30 June 2010 (ML)	Balance at 01 July 2009 (ML)	Net movement in inter-valley trade account in 2009–10 (ML)
Murrumbidgee IVT	29,002	227,341	–198,339
Lower Darling IVT	68,400	0	68,400
Goulburn IVT	108,200	99,700	8,500
NSW–Vic transfer account	6,000	12,800	–6,800
NSW–SA transfer account	47,000	104,100	–57,100
Vic–SA transfer account	6,300	10,000	–3,700
Total	264,902	453,941	–189,039

The IVT accounts register the obligations to deliver traded water between valleys located in a same state:

Murrumbidgee IVT: between Murrumbidgee Valley in New South Wales and Murray New South Wales Valley. A positive balance in the above table for this IVT means that water is owed by the Murrumbidgee to the Murray New South Wales. The negative net movement in the IVT means that the net obligation of Murrumbidgee to deliver traded water to the Murray New South Wales has decreased during the 2009–10 year. The large balances on the Murrumbidgee IVT account reflect high demand to trade water from the Murrumbidgee to other Murray system water users.
Lower Darling IVT: between Lower Darling Valley in New South Wales and Murray New South Wales Valley. A positive balance in the above table for this IVT means that water is owed by the Lower Darling to the Murray New South Wales. The positive net movement in the IVT means that net obligation of Lower Darling to deliver traded water to Murray New South Wales has increased during the 2009–10 year.
Goulburn IVT: between Goulburn Valley in Victoria and Murray Victoria Valley. A positive balance in the above table for this IVT means that water is owed by the Goulburn Valley to the Murray Victoria. The positive net movement in the IVT means that net obligation of Goulburn Valley to deliver traded water to Murray Victoria has increased during the 2009–10 year.

Inter-state transfers accounts register the obligations to deliver traded water between valleys of different states:

New South Wales – Victoria transfer account: between Murray New South Wales Valley and Murray – Victoria Valley. A positive balance in the above table for this transfer account means that water is owed by the Murray New South Wales to the Murray – Victoria. The negative net movement in the transfer account means that the net obligation of Murray New South Wales to deliver traded water to Murray – Victoria has decreased during the 2009–10 year.
New South Wales – South Australia transfer account: between Murray New South Wales Valley and Murray South Australia Valley. A positive balance in the above table for this transfer account means that water is owed by the Murray New South Wales to the Murray South Australia. The negative net movement in the transfer account means that the net obligation of Murray New South Wales to deliver traded water to Murray South Australia has decreased during the 2009–10 year.
Victoria – South Australia transfer account: between Murray Victoria Valley and Murray South Australia Valley. A positive balance in the above table for this transfer account means that water is owed by the Murray Victoria to the Murray South Australia. The negative net movement in the transfer account means that the net obligation of Murray Victoria to deliver traded water to Murray South Australia has decreased during the 2009–10 year.

Valleys’ net changes of water assets and water liabilities

The table below presents the volumes by valley of the net movements in the inter-valley and inter-state trade accounts during 2009–10. As all trades occurred within the Murray–Darling Basin region, the total of the net movements in the trade accounts is zero.

In the table below:

a positive value indicates an increase of the obligation (water liability) of a valley to deliver traded water, or a decrease of its claim (water asset) to receive traded water
a negative value indicates a decrease of the obligation (water liability) of a valley to deliver traded water, or an increase of its claim (water asset) to receive traded water.

Method

WAM data were obtained from water trade registers.

Inter-valley trade account is the remaining volume of traded water to be delivered after consideration of:

balance of the account at the start of the water year
allocation (temporary) trades registered during the current water year (mostly allocation trade plus a very small proportion of tagged trade)
previous (permanent) entitlement trades and allocation levels from the source valleys that determine the volume of tagged trade
settlement of trade by physical transfer of water between valleys during the year (e.g. delivery of water from the Murrumbidgee to the Murray system at Balnarald)
other transfers between the relevant valleys or accounts. Exampls of this is the settlement of the Murrumbidgee IVT account (between Murrumbidgee and Murray), via the Snowy transfers, by reducing the required annual releases from Snowy Hydro to the Tumut River and increasing the required annual release to the Murray River (see Line item 7.1 Claim to water in other entity – remaining in the water accounting statement notes)
adjustments and forfeitures on allocations in the source valleys.

Uncertainty

Uncertainty is ungraded.

Assumptions, approximations, caveats/limitations

Inter-valley trade account – subject to revision – inputs to the calculation are generally well audited; however, the permanent trade volumes are currently under review.

Impact on the liability of the valleys to deliver water to the users

When water is traded from a source valley to a destination valley, the obligation (water liability) to deliver the allocated water to the user is transferred from the source to the destination valley. The newly created liability in the destination valley will be settled when the allocated water is diverted by the purchaser of the water trade (allocation trade or tagged trade). Adjustments and forfeiture of allocations in the source valley may also impact on the liability remaining at the end of the water year for the destination valley.

These transactions are not explicitly reported here but their volumes are included in the water allocations and diversions volumes reported in the Water Accounting Statements.
