Note—

The environmental flow rules in clause 26 mitigate alterations to natural flow regimes in this water source by ensuring translucent flows are released from water storages in this water source for environmental use.

(c)  maintain hydrological connectivity between this water source and wetlands associated with this water source, and

Note—

The rules in clause 26 maintain hydrological connectivity between this water source and wetlands associated with this water source by ensuring flows are achieved below Lake Brewster.

(d)  support environmental events in wetlands associated with this water source such as bird breeding, fish passage and weed management, and

Note—

The rules in clause 27 ensure that environmental water allowances are maintained and may be released to support environmental events.

(e)  contribute to critical downstream environmental and water quality events, and

Note—

The rules in clause 28 ensure that a water quality allowance is maintained and lists purposes, including mitigation of blue green algae and reduction in salinity levels, for which the water quality allowance water can be released from Wyangala Dam and Lake Brewster.

(f)  minimise the impact of the river regulation and water extraction on the environment in this water source and the wetlands associated with this water source.

Notes—

1 The following rules in this Plan ensure that the impact on the environment from Wyangala Dam releases and the delivery of water orders are minimised: (a) the rules in clause 32 for water delivery and channel capacity constraints, (b) the rules in clause 35 for rates of change to storage releases.

2 The environmental water allowance rules in clause 27 also minimise the impact of river regulation and water extraction.

(3)  The environmental performance indicator for this Plan is the extent to which the rules and strategies in this Plan have contributed to meeting the environmental objectives in subclause (1) over its term.

(4)  The performance indicator in subclause (3) will be assessed by:

(a)  comparing the ecological condition of this water source at the commencement of this Plan and at the expiration of this Plan by measuring the change in factors including:

(i)  condition indicators in this water source, which may include changes in:

(A)  the diversity of ecological communities, reproductive success of key species and the habitat or recorded range of fish, macroinvertebrates or vegetation, or

(B)  geomorphology, including evidence of fine sediment scour and instream habitat diversity, or

(C)  the river condition index of key river reaches, and

(ii)  the hydrological regime for this water source, including low, moderate and high flows, and

(b)  considering the extent to which changes in the ecological condition of this water source can be attributed to the rules and strategies in this Plan.

(b)  provide flexibility for licence holders to use water in a way that reflects the reliability characteristics of their access licence category, and

Note—

The rules for managing access licences in Part 9 of this Plan provide flexibility that reflects the characteristics of the licence category.

(c)  establish a long-term average annual extraction limit and rules for managing extractions within that extraction limit that recognise different climatic conditions in different years, and

Note—

The application of the long-term average annual extraction limit and the assessment and compliance rules in Part 7 of this Plan manage extractions to different climatic conditions in different years.

(d)  provide opportunities for market-based trading of water within environmental and system constraints.

Note—

The rules in Part 10 of this Plan permit a variety of dealings within environmental and system constraints, including permanent trade of water access licences, trade of water allocations and ability to move a water access licence from one location to another.

(3)  The economic performance indicator for this Plan is the extent to which the rules and strategies in this Plan have contributed to meeting the economic objectives in subclause (1) over its term.

(4)  The performance indicator in subclause (3) will be assessed by:

(f)  recognises and is consistent with the water management principles set out in section 5 of the Act.

13 Climatic variability

This Plan recognises the effects of climatic variability on river flow in this water source by having provisions that:

(a)  manage the sharing of water in this water source within the limits of water availability on a long-term average annual basis and the priorities according to which water allocations are to be adjusted as a consequence of any reduction in the availability of water due to an increase in the average annual extraction against the long-term average annual extraction limit, under Division 1 of Part 7 of this Plan, and

(b)  manage the sharing of water between categories of access licences on an annual basis in this water source, through the available water determination rules specified in Division 2 of Part 7 of this Plan.

Note—

Other statutory tools are available to manage for climatic variability within a water source, for example, temporary water restrictions under section 324 of the Act.

Part 4 Planned environmental water provisions

Note—

This Part is made in accordance with sections 8, 8A and 20 of the Act.

14 General

This Part contains environmental water rules for the commitment, identification, establishment and maintenance of planned environmental water in this water source.

Note—

In accordance with the Act, planned environmental water is water that is committed by management plans for fundamental ecosystem health or other specified environmental purposes, either generally or at specified times or in specified circumstances and that cannot, to the extent committed, be taken or used for any other purpose.

15 Commitment and identification of planned environmental water

Water is committed and identified as planned environmental water in this water source in the following ways:

(a)  by reference to the commitment of the physical presence of water in this water source,

(b)  by reference to the long-term average annual commitment of water as planned environmental water,

(c)  by reference to the water that is not committed after the commitments to basic landholder rights and for sharing and extraction under any other rights have been met.

16 Establishment and maintenance of planned environmental water

(1)  Planned environmental water is established in this water source as follows:

(a)  it is the physical presence of water that results from:

(i)  the environmental flow rules, as specified in clause 26, and

Note—

The environmental flow rules in clause 26 ensure that environmental flows are released from water storages in this water source.

(ii)  the environmental water allowance rules, as specified in clause 27, and

Note—

The environmental water allowance rules in clause 27 ensure water is reserved and released for environmental purposes from Wyangala Dam and Lake Brewster.

(iii)  the water quality allowance rules for water quality management purposes, as specified in clause 28,

Note—

The water quality allowance rules in clause 28 ensure that water is credited to a water quality allowance and that releases may be made from this allowance for water quality purposes.

(b)  it is the long-term average annual commitment of water as planned environmental water in this water source that results from the application of the long-term average annual extraction limit and compliance rules as specified in Division 1 of Part 7 of this Plan and the available water determination rules as specified in Division 2 of Part 7 of this Plan,

Notes—

1 By limiting long-term average annual extractions to an estimated 305,000 megalitres per year, this Plan ensures that approximately 75% of the long-term average annual flow in this water source (estimated to be 1,212,000 megalitres per year) will be preserved and will contribute to the maintenance of basic ecosystem health.

2 The rules in Part 7 of this Plan ensure that there will be water remaining in this water source over the long-term by maintaining compliance with the long-term average annual extraction limit. The rules in Part 7 of this Plan provide for a reduction in available water determinations when the long-term average annual extraction limit has been assessed to have been exceeded.

(c)  it is the water remaining in this water source after water has been taken pursuant to basic landholder rights and access licences, in accordance with the rules specified in Parts 7 and 9 of this Plan.

(2)  The planned environmental water established under subclause (1) (a) is maintained in this water source by:

(a)  the environmental flow rules as specified in clause 26, and

(b)  the environmental water allowance rules as specified in clause 27, and

(c)  the water quality allowance rules as specified in clause 28.

(3)  The planned environmental water established under subclause (1) (b) is maintained in this water source by the application of the long-term average annual extraction limit and compliance rules as specified in Division 1 of Part 7 of this Plan and the available water determinations as specified in Division 2 of Part 7 of this Plan.

(4)  The planned environmental water established under subclause (1) (c) is maintained in this water source by the rules specified in Parts 7 and 9 of this Plan.

Part 5 Requirements for water

Division 1 General

17 Application

(1)  This Part identifies the requirements for water from this water source for basic landholder rights (Division 2) and for extraction under access licences (Division 3).

(2)  The volumes of water specified in this Part represent the estimated water requirements of persons entitled to basic landholder rights in this water source and the total volumes or unit shares specified in the share components of all access licences in this water source. The actual volumes of water available for extraction in this water source at any time will depend on factors such as climatic variability, access licence priority and the rules in this Plan.

(3)  This Plan recognises that basic landholder rights in this water source and the total share components of all access licences authorised to take water from this water source may change during the term of this Plan. This Plan manages such changes by having provisions that manage the sharing of water within the limits of water availability, as provided for in Division 1 of Part 7 of this Plan.

Note—

The total share components of access licences in this water source may change during the term of this Plan as a result of:

(a)  the grant, surrender or cancellation of access licences in this water source, or

(b)  the variation of local water utility licences under section 66 of the Act.

Division 2 Requirements for water for basic landholder rights

18 Domestic and stock rights

At the commencement of this Plan, the water requirements of persons entitled to domestic and stock rights in this water source are estimated to total 1,163 megalitres per year (ML/year).

Notes—

1 Domestic and stock rights are set out in Division 1 of Part 1 of Chapter 3 of the Act and must be exercised in accordance with any mandatory guidelines established under the Act with respect to the taking and use of water for domestic consumption or stock watering. The figures for these rights listed in this clause do not refer to licensed volumes.

2 Inherent water quality and land use activities may make the water in some areas unsuitable for human consumption. Water from this water source should not be consumed without first being tested and, if necessary, appropriately treated. Such testing and treatment is the responsibility of the water user.

19 Native title rights

At the commencement of this Plan, there are no native title rights in this water source. Therefore the water requirements for native title rights are 0 ML/year.

Note—

A change in the native title rights may occur pursuant to the provisions of Native Title Act 1993 of the Commonwealth.

Division 3 Requirements for water for extraction under access licences

Notes—

1 The share component estimates in this Division 3 include volumes for licensed environmental water. The Environmental Water Register established and maintained by the Department provides a record of environmental water licences, planned environmental water rules and adaptive environmental water plans approved by the Minister. The register can be accessed from http://ewr.water.nsw.gov.au/ewr/main/ewrHome.

2 In this water source there are two access licences with adaptive environmental water conditions held by the NSW Minister for Environment totalling 13,000 megalitres. There are 15 other access licences of held environmental water totalling 114,336 megalitres that do not have adaptive environmental water conditions. Some of these are held by the Commonwealth Government and others by the NSW Government. These access licences are regulated river (general security) or regulated river (high security) access licences.

20 Share component of domestic and stock access licences

It is estimated that at the time of commencement of this Plan the share components of domestic and stock access licences authorised to take water from this water source total 12,502 ML/year.

21 Share component of local water utility access licences

It is estimated that at the time of commencement of this Plan the share components of local water utility access licences authorised to take water from this water source total 15,545 ML/year.

22 Share component of regulated river (high security) access licences

It is estimated that at the time of commencement of this Plan the share components of regulated river (high security) access licences authorised to take water from this water source total 27,680 unit shares.

23 Share component of regulated river (general security) access licences

It is estimated that at the time of commencement of this Plan the share components of regulated river (general security) access licences authorised to take water from this water source total 592,801 unit shares.

24 Share component of regulated river (conveyance) access licence

It is estimated that at the time of commencement of this Plan the share components of regulated river (conveyance) access licences authorised to take water from this water source total 17,911 unit shares.

25 Share component of supplementary water access licences

There are no supplementary water access licences authorised to take water from this water source.

Part 6 System operation requirements

Notes—

1 This Part is made in accordance with section 21 (e) of the Act.

2 Part 12 allows for amendments to be made to this Part.

Division 1 Environmental water rules

26 Environmental flow rules for this water source

(1)  Environmental flows must be released according to the rules in this clause.

(2)  Subject to subclause (4), translucent flows must be released from Wyangala Dam:

(a)  during the period of 15 May to 15 November in any given year, and

(b)  when the inflows to Wyangala Dam since 1 January that calendar year have been greater than 250,000 megalitres (ML), and

(c)  whenever the sum of inflows to Wyangala Dam plus tributary inflows downstream of Wyangala Dam are capable of producing a flow in the Lachlan River at Lachlan Lake Brewster Weir gauge (412048) greater than:

(i)  4,000 megalitres per day (ML/day), when the volume of water held in Wyangala Dam is less than or equal to 50% of the full supply volume, or

Note—

Translucent flows and full supply volume are defined in the Dictionary.

(3)  The rate of release of translucent flows released under subclause (2) must be the lesser of:

(a)  inflows to Wyangala Dam, and

(b)  the release necessary to achieve a flow in the Lachlan River at Lachlan Lake Brewster Weir gauge (412048) of:

(i)  4,000 ML/day plus 25 ML/day for each 1% by which the volume of water held in Wyangala Dam exceeds 0% of the full supply volume, when the volume of water held is less than or equal to 50% of the full supply volume, and

(ii)  3,500 ML/day plus 31.25 ML/day for each 1% by which the volume of water held in Wyangala Dam exceeds 0% of the full supply volume, when the volume of water held is greater than 50% of the full supply volume but less than or equal to 80% of the full supply volume, and

(iii)  6,000 ML/day plus 100 ML/day for each 1% by which the volume of water held in Wyangala Dam is greater than 80% of the full supply volume.

Note—

Subclause (3) (b) (iii) is the maximum release from Wyangala Dam when it is full and is the release necessary to achieve a flow at Lachlan Lake Brewster Weir gauge (412048) of 8,000 ML/day.

(4)  Translucent flows must not be released when flows at Lachlan Lake Brewster Weir (412048), as measured since 1 June that water year, have exceeded 350,000 ML plus the sum of the following over the same period:

(a)  downstream water orders and any losses associated with delivery of these orders,

(b)  replenishment flows to effluents downstream of Lake Brewster and any losses associated with the delivery of those replenishment flows,

(c)  the volume of water downstream of Lake Brewster Weir resulting from evacuation of airspace made under clause 37,

(6)  Tributary inflows occurring when translucent flows are being released under this clause must not be used to supply access licence requirements or basic landholder rights or be diverted to or stored in any weir or water storages, except to the extent that they are in excess of the flow required to meet the flow rates specified in subclause (2) (c).

Note—

If flows are insufficient to satisfy subclause (2) (c), or the conditions specified in subclauses (2) (a) or (b) or (4), tributary inflows may be diverted and stored in Lake Cargelligo or Lake Brewster, consistent with normal operational management.

(7)  Releases of water from Lake Cargelligo and Lake Brewster may be substituted for all or part of the translucent flows released from Wyangala Dam if releasing the translucent flows from Wyangala Dam is likely to cause flooding.

(8)  Water released in accordance with subclause (7) from Lake Brewster must be accounted as translucent flows passing at Lake Brewster Weir for the purposes of subclause (4).

(9)  In the event that the release capacity of Wyangala Dam is insufficient to produce the release rates specified in subclause (3) (b) in addition to the releases required to satisfy access licence orders:

(a)  releases are to equal the release capacity,

(b)  releases to satisfy water orders are permitted to be taken in accordance with access licence water orders,

(c)  the volume of the translucent flows released will equal the total volume of water released from Wyangala Dam minus the volume of water released to satisfy access licence holder orders,

(d)  the volume of translucent flows required to be released under subclause (3) but not released under this subclause is to be accrued and released at the earliest opportunity, and

(e)  releases made under paragraph (d) are not to be subject to the timing and release rate restrictions in subclauses (2) and (3), but are subject to the maximum release rules specified in subclause (4).

cl 26: Am 2016 No 55, Sch 3.44 [2].

27 Environmental water allowances

(1)  Two environmental water allowances (EWAs) will be maintained for environmental purposes:

(a)  an environmental water allowance held in Wyangala Dam, known as the Wyangala Environmental Water Allowance (Wyangala EWA), and

(b)  an environmental water allowance held in Lake Brewster, known as the Lake Brewster Environmental Water Allowance (Brewster EWA).

(2)  The Wyangala EWA and Brewster EWA will each be credited with a volume equal to 10,000 ML:

(a)  on 1 July each year, if the total volume of water in the water allocation accounts of regulated river (general security) access licences exceeds 50% of the total volume of regulated river (general security) access licence share components, or

(b)  in any water year when the EWAs were not credited on 1 July, when the sum of the volume of water in the water allocation accounts of regulated river (general security) access licences at 1 July, plus the volume of water provided by available water determinations for those licences during the water year, is equivalent to 75% of total regulated river (general security) share components.

(3)  Subject to subclause (4), releases from Wyangala EWA and Brewster EWA may be made for environmental purposes including, but not limited to, the following:

(a)  to support the completion of waterbird breeding events,

(b)  to support native fish breeding and fish passage,

(c)  to provide wetland watering,

(d)  to increase flow variability,

(e)  to support environmental assets or environmental functions within and downstream of this water source that have been identified as water-dependent Aboriginal cultural values,

Note—

The values referred to in paragraph (e) will be identified by the Aboriginal Water Initiative and stored on the Aboriginal Water Initiative System database.

(4)  The volume of Brewster EWA available for release from Lake Brewster at any time must be the lesser of:

(a)  the volume of credit remaining in the Brewster EWA, and

(b)  the active storage in Lake Brewster,

minus any water transferred from Wyangala Dam for operational reasons.

Note—

Active storage is defined in the dictionary.

(5)  Any credits remaining in Wyangala EWA and Brewster EWA are to be forfeited at the end of each water year.

Note—

It is not possible to forecast when releases of water from the Wyangala EWA and Lake Brewster EWA will be required, as releases occur in response to unpredictable environmental circumstances. To allow estimation of the effect of the Wyangala EWA and Lake Brewster EWA rules on water extractions computer modelling has assumed that a total of 5,000 megalitres of Wyangala EWA and of Lake Brewster EWA were released at the end of each year when there was water in the accounts. It is expected that, over the life of the Plan, average releases from each account would not exceed these figures.

(6)  The Minister should seek the advice of an environmental water advisory group in making releases under this clause.

Notes—

1 At the commencement of this Plan the NSW Office of Environment and Heritage ( OEH ) is responsible for managing environmental water allowances established under water sharing plans. OEH also administers and supports Environmental Water Advisory Groups ( EWAGs ) to inform the management of environmental water allowances and licensed environmental water (Division 3 of Part 5), including providing advice to the Minister. Information on EWAGs is available from OEH’s website at www.environment.nsw.gov.au.

2 At the commencement of this Plan, OEH manages an EWAG for the Lachlan catchment called the Lachlan Riverine Working Group.

28 Water quality allowance

Division 2 General system operations rules

29 Maintenance of water supply

(1)  The water supply system must be managed so that:

(a)  it would be capable of maintaining supply on an annual basis to those exercising domestic and stock rights and native title rights in this water source through a repeat of the worst period of low inflows into this water source, as represented in flow information held by the Department when the first water sharing plan for this water source made under the Act came into force, and

(b)  available water determinations of 100% of share components can be maintained for domestic and stock access licences and local water utility access licences through a repeat of the worst period of low inflows to this water source, as represented in flow information held by the Department when the first water sharing plan for this water source made under the Act came into force, and

(c)  available water determinations for regulated river (high security) access licences of 1 ML per unit share can be maintained through a repeat of the worst period of low inflows to this water source, as represented in flow information held by the Department when the first water sharing plan for this water source made under the Act came into force.

(2)  To meet the requirements of subclause (1), sufficient volumes of water must be set aside from inflows into this water source and in reserves held in Wyangala Dam or other water storages.

(3)  Sufficient volumes of water must be set aside from inflows into this water source and in reserves in Wyangala Dam or other water storages to provide for replenishment flows in clause 30.

Notes—

1 The first water sharing plan for this water source made under the Act was the Water Sharing Plan for the Lachlan Regulated River Water Source 2003 .

2 Water supply system and reserves are defined in the Dictionary.

30 Replenishment flows

(1)  The Minister will determine the volume of replenishment flows to be provided in any water year that are necessary to meet the domestic and stock requirements for the following, up to the maximum volume specified:

(a)  12,000 ML/year to Willandra Creek downstream from Homestead Weir to the Ivanhoe/Balranald Road (Grid Reference 229700 east, 6333000 north, Kilfera Map, 1:100,000, Sheet 7731),

Note—

This volume includes water for the township of Ivanhoe and Morrison’s Lake.

(b)  9,000 ML/year to the Merrowie Creek Trust District downstream to Cuba Dam (Grid Reference 266800 east, 6249000 north, Tarwong Map, 1:50,000, Sheet 7730),

(2)  Booberoi Creek is to receive a continuous supply at its off-take at a rate sufficient to provide for town and domestic supply and stock watering and produce a visible flow at the Ginniguldrie Road Bridge, providing that the net volume supplied does not exceed 12,500 ML in any water year.

Note—

The circumstances under which the replenishment flows specified in subclause (1) are to be provided will be specified as conditions on the water supply work approval held by Water NSW.

31 Minimum flow rule

A visible flow should be maintained in the Lachlan River at Geramy.

Note—

The visible flow at Geramy also ensures water is available for basic human needs including domestic and stock purposes at the end of this water source.

32 Water delivery and channel capacity constraints

(1)  Where necessary for determining numerical extraction components, managing water releases or providing water under access licences, the maximum delivery or operating channel capacity in this water source or in any section of this water source will be determined and specified in accordance with procedures established by the Minister, taking into account the following:

(a)  inundation of private land or interference with access,

(b)  the effects of inundation on the floodplain and associated wetlands,

(c)  the transmission losses expected to occur,

(m)  600 ML/day downstream of Corrong.

33 Priority of extractions for access licences

(1)  Where the extraction component of an access licence in this water source does not specify a rate of extraction as a share of supply capability or a volume per unit of time, the following priority of extraction will apply whenever supply capability is insufficient to satisfy all orders for water in any section of this water source:

(a)  water will be supplied to domestic and stock access licences, local water utility access licences and water ordered from the AWD subaccount of regulated river (high security) access licences that have placed orders for water, in that order,

(b)  then, any remaining supply capability will be shared between regulated river (general security) access licences, regulated river (conveyance) access licences, and water ordered from the Spillable subaccount of regulated river (high security) access licences that have placed orders for water, in accordance with a method approved by the Minister.

Note—

Supply capability is defined in the Dictionary.

(2)  For the purposes of subclause (1), AWD subaccount and Spillable subaccount have the same meaning as they have in clause 50.

(3)  Advice from water user representatives should be sought prior to the method in subclause (1) (b) being approved.

Notes—

1 During periods of channel capacity constraint, the implementation of the above provisions may result in ordering delays and an inability to supply water requirements from regulated water deliveries on a daily basis.

2 The Department will use meetings with the Lachlan Customer Service Committee as a means to consult with water user representatives.

cl 33: Am 2016 No 55, Sch 3.44 [3].

34 Numerical specification of extraction components

(1)  The extraction of water components of access licences in this water source that are affected by a physical supply constraint may be amended under section 68A of the Act to specify a volume per unit of time or share of supply capability in order to share the impacts of any physical supply constraint among access licences.

(2)  The rate of shares specified in the amended extraction components under subclause (1) for domestic and stock access licences, local water utility access licences and regulated river (high security) access licences should, where possible, be the amount which, in the Minister’s opinion, is sufficient to satisfy the maximum daily requirements of the access licences in that order.

(3)  the rate of shares specified in the amended extraction components under subclause (1) for regulated river (general security) access licences and regulated river (conveyance) access licences should be in proportion to the share components for each access licence.

(4)  When action under subclause (1) is undertaken, the Minister may also amend the extraction components of access licences in other sections of the water source that are not affected by the physical supply constraint to exclude extraction components in sections of the water source affected by that action.

cl 34: Am 2016 No 55, Sch 3.44 [4].

35 Rates of change of releases from water storages

(1)  Changes in release rates from water storages in this water source must be made in accordance with rules established by the Minister.

(2)  The rules established by the Minister will take into account the following:

(a)  relevant environmental considerations,

(b)  damage to river banks,

(c)  public safety,

(d)  any other matters considered relevant by the Minister.

36 Dam operation during floods and spills

(1)  The operation of Wyangala Dam during times of floods and spills of water is to be undertaken in a manner that maintains the safety of dam infrastructure.

(2)  To the extent that it is consistent with subclause (1), operation should leave Wyangala Dam as full as possible at the completion of the flood event, subject to maintenance of a target airspace volume as specified in clause 37 (b), and should aim to lessen downstream flood damage, where possible.

Note—

Airspace is defined in the Dictionary.

37 Airspace operation rules

Airspace operation of Wyangala Dam must be undertaken in accordance with the following rules:

(a)  airspace is to be maintained in Wyangala Dam for the purpose of reducing downstream flood damage,

(b)  the target airspace volume that is to be maintained at any time, must be set so that the probability of the water storage volume being full by the time significant irrigation demand commences is at least 80%,

(c)  evacuation of airspace should not result in flow at Cotton’s Weir, Forbes or Jemalong Weir exceeding the minor flood level at these sites,

(d)  when Wyangala Dam is within 1% of the airspace target, airspace evacuation releases are to be maintained at the Wyangala power station capacity, if practicable.

Part 7 Limits to the availability of water

Note—

Part 12 allows for amendments to be made to this Part.

Division 1 Long-term average annual extraction limit

38 General

The availability of water for extraction in this water source on a long-term basis is to be managed in accordance with this Part.

39 Volume of the long-term average annual extraction limit

(1)  The long-term average annual extraction limit for this water source is the lesser of the following:

(a)  the long-term average annual extraction from this water source that would occur with:

(i)  the water storages and water use development that existed in 1999/2000, and

Note—

Water use development is defined in the Dictionary.

(ii)  the share components of water access licences existing at commencement of the Water Sharing Plan for the Lachlan Regulated River Water Source 2003, and

(iii)  the rules defined in the Water Sharing Plan for the Lachlan Regulated River Water Source 2003, and

(iv)  the maximum crop area and the crop planting behaviour that was in place at the commencement of the Water Sharing Plan for the Lachlan Regulated River Water Source 2003,

(b)  the long-term average annual extraction from this water source that would occur under Cap baseline conditions as agreed under the Murray-Darling Basin Agreement in Schedule 1 to the Water Act 2007 of the Commonwealth.

(2)  The values referred to in subclauses (1) (a) and (b) will be adjusted for any access licence dealings under sections 71Q, 71R or 71U of the Act that occur between water sources within this water management area.

Notes—

1 An assessment of the long-term average annual extraction that would result from conditions specified in subclause (1) (a) has been made using the Lachlan IQQM computer model scenario run number E229. This indicates a long-term average annual extraction volume of 305,000 ML/year at the commencement of the Water Sharing Plan for the Lachlan Regulated River Water Source 2003 .

2 An assessment of the long-term average annual extractions that would result from Cap baseline conditions specified in subclause (1) (b) using the Lachlan IQQM computer model scenario run number C071A, indicated a long-term average annual extraction volume of 315,000 ML/year at the commencement of the Water Sharing Plan for the Lachlan Regulated River Water Source 2003 .

3 By limiting long term average annual extractions to an estimated 305,000 ML/year this Plan ensures that approximately 75% of the long-term average annual flow in this water source (estimated to be 1,212,000 ML/year) will be preserved and will contribute to the maintenance of basic ecosystem health.

40 Calculation of the long-term average annual extraction limit and current average annual extractions

(1)  For the purposes of calculating the long-term average annual extraction limit and the current average annual extractions, the following must be included:

(a)  all water extractions under all categories of access licences, except where subclause (2) (c) applies,

(b)  all water extractions under domestic and stock rights and native title rights,

(c)  all extractions from the floodplain, except those under a water access licence that specifies another water source, that are used in conjunction with extractions under a water access licence in this water source,

(d)  water allocations assigned from water allocation accounts of access licences in this water source to water allocation accounts of access licences in another water source.

(2)  For the purposes of calculating the long-term average annual extraction limit and current average annual extractions, the following must not be included:

(a)  the use of water pursuant to the environmental water rules and environmental water allowance rules in Divisions 1 and 2 of Part 6,

(b)  replenishment flows made in accordance with Part 6,

(c)  water allocations assigned from water allocation accounts of access licences in any other water source to water allocation accounts of access licences in this water source.

Note—

Under section 8F of the Act the long-term average annual extraction limit is taken to be varied by the amount of any change to the amount of water committed as licensed environmental water, excluding water committed under section 8C of the Act. The variation in the long-term average annual extraction limit is to be determined in accordance with a methodology approved by the Minister and published in the Gazette.

41 Assessment of average annual extractions against long-term average annual extraction limit

(1)  An assessment of average annual extractions against the long-term average annual extraction limit is to be conducted as set out in this clause.

(2)  The assessment referred to be in subclause (1) is to be undertaken after the end of each water year, using the hydrologic computer model that, at the time, is approved by the Department for assessing long-term water extraction from this water source.

(3)  To assess the long-term average annual extraction limit, the model referred to in subclause (2) must be set to represent as close as possible the conditions referred to in clause 39 (1) (a) and (b).

(4)  To assess current long-term average annual extraction from this water source the model referred to in subclause (2) must be set to represent as closely as possible all water use development, water supply system management and other factors affecting the quantity of long-term average annual extraction from this water source at the time of the assessment.

42 Compliance with the long-term average annual extraction limit for this water source

(1)  The long-term average annual extraction from this water source may not be permitted to exceed the long-term average annual extraction limit specified in clause 39.

(2)  Pursuant to subclause (1), if it has been assessed that current average annual extraction from this water source exceeds:

(a)  the volume specified in clause 39 (1) (a) by 3% or more, or

(b)  the volume specified in clause 39 (1) (a) by more than half the difference between the volume specified in clause 39 (1) (a) and the volume specified in clause 39 (1) (b), or

(c)  the volume specified in clause 39 (1) (b), or

(d)  the volume specified in clause 39 (1) (a) for 3 consecutive water years,

then the maximum volume that may be taken from a regulated river (general security) access licence as specified in clause 54 (1) (a) must be reduced in accordance with subclause (3) of this clause.

(3)  The reduction under subclause (2) is to be of an amount that is, in the Minister’s opinion, necessary to return the long-term average annual extractions in this water source to the long-term average annual extraction limit.

(4)  If action has been taken under subclause (2), and a subsequent assessment under clause 41 indicates that the current long-term average annual extraction is below the long-term average annual extraction limit by more than 3%, or by more than half the difference between the volume specified in clause 39 (1) (a) and the volume specified in clause 39 (1) (b), then previous reductions under subclause (2) may be reversed to the degree that is, in the Minister’s opinion, necessary to return the long-term average annual extractions to the long-term average annual extraction limit.

(5)  The assessment of the degree of any reduction required under subclause (2) or any reversal under subclause (4) must be made using the same computer model used to carry out assessments under clause 41.

(6)  Before taking action under subclauses (2) or (4), the Minister should consult with water user representatives on:

(a)  the data used in the computer model referred to in clause 41, and

(b)  the proposed actions to be taken in accordance with subclause (2) or (4).

Note—

The Department will use meetings with the Lachlan Customer Service Committee as a means to consult with water user representatives.

Division 2 Available water determinations

Assessments indicate that when Wyangala Dam, Lake Brewster and Lake Cargelligo are full it should be possible for each general security access licence account to hold a maximum 1.36 ML/unit of share component.

48 Available water determinations for regulated river (conveyance) access licences

(1)  In making available water determinations for regulated river (conveyance) access licences, the Minister should consider the rules in this clause.

(2)  Subject to subclauses (3)–(7), an available water determination for regulated river (conveyance) access licences should be made at the commencement of each water year and whenever an available water determination is made for regulated river (general security) access licences.

(3)  The available water determination made under subclause (2) should take into consideration the total water availability for regulated river (general security) access licences that are used to supply water to Jemalong Irrigation Limited’s area of operation and the total volume of water required to meet Jemalong Irrigation Limited’s conveyance loss in that water year.

(4)  Before making an available water determination under subclause (2), the total water availability in ML/unit of share component for regulated river (general security) access licences that are used to supply water to Jemalong Irrigation Limited’s area of operation should be determined using the formula:

 
where:

GS₁ is the total water allocation in the Take subaccounts of regulated river (general security) access licences that are used to supply water to Jemalong Irrigation Limited’s area of operation at the commencement of the water year, except where subclause (7) applies.

GS₂ is the total volume of water credited to the water allocation accounts of regulated river (general security) access licences that are used to supply water to Jemalong Irrigation Limited’s area of operation, from regulated river (general security) access licence available water determinations made in that water year, except where subclause (7) applies.

GS_SC is the total share components of regulated river (general security) access licences that are used to supply water to Jemalong Irrigation Limited’s area of operation.

(5)  For the purposes of subclause (4), Take subaccount has the same meaning as it has in clause 50.

(6)  The total volume of water required to meet Jemalong Irrigation Limited’s conveyance loss in that water year, should be equal to:

(a)  2,400 ML plus 570 ML for each 0.01 ML/unit of share component calculated under subclause (4), when the result of that calculation is less than or equal to 0.2 ML/unit of share component,

(b)  13,800 ML plus 74.745 ML for each 0.01 ML/unit of share component calculated above 0.2 ML/unit of share component under subclause (4), when the result of that calculation is greater than 0.2 ML/unit of share component and less than 0.75 ML/unit of share component, and

(c)  17,911 ML when the result of the calculation made under subclause (4) is equal to or greater than 0.75 ML/unit of share component.

(7)  The available water determination made under subclause (2) should be determined using the formula:

 
where:

CL₂ is the total volume of water required to meet Jemalong Irrigation Limited’s conveyance loss calculated under subclause (6).

CL₁ is the total volume of water required to meet Jemalong Irrigation Limited’s conveyance loss calculated under subclause (6) at the time the previous available water determination for regulated river (conveyance) access licences was made in that water year, except where subclause (8) applies.

TC_sc is the total share components of regulated river (conveyance) access licences.

(8)  Immediately following the withdrawal of water allocations from the water allocation accounts of regulated river (general security) access licences under clause 56 and prior to the making of an available water determination for regulated river (general security) access licences under clause 47 (3), the values of GS₁ and GS₂ to be used in subclause (4) and CL₁ to be used in subclause (7) are zero.

Part 8 Rules for granting access licences

Notes—

1 This Part is made in accordance with sections 20, 61 and 63 of the Act.

2 Access licences granted in this water source will be subject to mandatory conditions and may be subject to discretionary conditions.

49 Specific purpose access licences

Note—

Section 61 of the Act allows for the granting of specific purpose access licences under the regulations and the relevant water sharing plan. Only those specific purpose access licences listed in clause 10 of the Water Management (General) Regulation 2011 can be granted under the regulations. The licences that may be applied for under subclause (2) of this clause are in addition to applications for the categories and subcategories of specific purpose access licences that may be made in accordance with clause 10 of the Water Management (General) Regulation 2011. The restrictions in subclause (3) of this clause apply to the granting of specific purpose access licences.

(1)  A specific purpose access licence must not be granted in this water source unless the Minister is satisfied that the share and extraction component of the access licence is the minimum required to meet the circumstances in which the access licence is proposed to be used.

(2)  Applications may be made for domestic and stock (subcategory “stock”) access licences in this water source.

(3)  Applications may not be made for an access licence of the subcategory “Aboriginal cultural” if the share component of the proposed access licence is more than 10 ML/year.

(4)  An access licence of the subcategory “Aboriginal cultural” may only be granted for the taking of water by an Aboriginal person or Aboriginal community for any personal, domestic or communal purpose, including drinking, food preparation, washing, manufacturing traditional artefacts, watering domestic gardens, cultural teaching, hunting, fishing, gathering and for recreational, cultural and ceremonial purposes.

Note—

Aboriginal person is defined in the Dictionary.

Part 9 Rules for managing access licences

Notes—

1 Part 12 of this Plan allows for amendments to be made to this Part.

2 The Act provides for the keeping of water allocation accounts for access licences. The rules in this Part impose further restrictions on the volume of water that may be taken under an access licence over a specified period of time. These restrictions are in addition to any other limits on access licences for the taking of water. It is an offence under the Act to take water under an access licence for which there is no or insufficient water allocation.

50 General

(1)  The rules in this Part apply to the management of water allocations in the water allocation accounts of access licences with a share component that specifies this water source.

(2)  The water allocation accounts of all regulated river (high security) access licences must comprise two subaccounts, referred to as the available water determination subaccount (AWD subaccount) and the Spillable subaccount.

(3)  The water allocation accounts for regulated river (general security) access licences must comprise two subaccounts, referred to as the Take subaccount and the Hold subaccount.

Notes—

1 The Spillable subaccount holds water allocations that are assigned to the regulated river (high security) access licence from the Take subaccount of a regulated river (general security) access licence during that water year under section 71T of the Act. The water in the Spillable subaccount will be withdrawn when Wyangala Dam spills and other storages are full. The AWD subaccount holds water allocations credited following an available water determination during that water year and any water allocations assigned from other access licences under section 71T of the Act and is unaffected when Wyangala Dam spills and other storages are full.

2 The Take subaccount holds water that may be taken by the licence holder this water year and the Hold subaccount holds water allocation that may not be taken by the licence holder during the current water year.

51 Crediting rules for water allocation accounts for regulated river (general security) and regulated river (high security) access licences

(1)  Water allocations for regulated river (high security) access licences must be credited into the AWD subaccount for those access licences in accordance with the available water determinations.

(2)  Water allocations accrued from available water determinations for regulated river (general security) access licences must be either of the following:

(a)  credited to the Take subaccount of a regulated river (general security) access licence whenever the total volume placed into that subaccount from available water determinations during the water year is less than  

where:

J equals the take limit multiplied by the number of unit shares in the share component of the access licence, where the take limit is as determined under clause 54 (1) (a).

K equals the volume in the Take subaccount at the commencement of the water year after any adjustments under clause 55.

L equals the volume of water withdrawn from the Take subaccount under clause 56.

(b)  otherwise credited to the Hold subaccount of a regulated river (general security) access licence.

52 Accounting for allocations assigned to and from regulated river (high security) access licences and regulated river (general security) access licences

(1)  Water allocations assigned under section 71T of the Act from an AWD subaccount of a regulated river (high security) access licence to another regulated river (high security) access licence must be credited to the AWD subaccount of the access licence.

(2)  Water allocations assigned under section 71T of the Act from a Spillable subaccount of a regulated river (high security) access licence to another regulated river (high security) access licence must be credited to the Spillable subaccount of the access licence.

Note—

Clause 61 (2) prevents the assignment of water allocations held in the Hold subaccount of a regulated river (general security) access licence to a regulated river (high security) access licence.

(8)  Unless otherwise specified in the water return flow rules established under section 75 of the Act, water allocations re-credited to regulated river (general security) access licences must be re-credited to the:

(a)  Take subaccount of the access licence where re-crediting occurs in the water year in which the water allocations were used, or

(b)  Hold subaccount of the access licence where re-crediting occurs in a water year subsequent to that in which the water allocations were used.

53 Debiting rules for water allocation accounts

(1)  Subject to subclause (2), the water allocation taken under domestic and stock access licences, local water utility access licences, regulated river (high security) access licences, regulated river (general security) access licences and regulated river (conveyance) access licences must be assessed and debited as the volume of water taken by the approved water supply works nominated by the access licence.

(2)  Upon written notice from the Minister to the licence holder, the water allocation taken under a domestic and stock access licence, a local water utility access licence, a regulated river (general security) access licence, a regulated river (high security) access licence and a regulated river (conveyance) access licence must be assessed and debited as the greater of:

(a)  the volume of water taken by the approved water supply works nominated by the access licence, or

(b)  the volume of water ordered for extraction by the approved water supply works nominated by the access licence,

for the term specified by the Minister.

(3)  The Minister should only take action under subclause (2) in accordance with the procedures specified in a water order debiting protocol approved by the Minister.

Note—

It is intended that the Minister may take action under subclause (2) where water orders have been exceeding the volume of water being taken under an access licence and this cannot be explained by rainfall or other unavoidable factors.

(4)  The water allocations taken under a regulated river (general security) access licence must be debited from the Take subaccount of the access licence.

(5)  The water allocations taken under a regulated river (high security) access licence are to be debited from the Spillable subaccount until the volume in that subaccount reaches zero, and then from the AWD subaccount, unless otherwise notified by the licence holder.

54 Maximum volume taken or held under a regulated river (general security) access licence

(1)  The maximum volume that may be taken during any water year from a regulated river (general security) access licence is equal to:

(a)  a take limit of 1 ML multiplied by the number of unit shares specified in the access licence share component, or such lower amount as required by clause 42, plus

(b)  the volume of water assigned to the access licence account from the Take subaccount of any regulated (general security) access licence during that water year, plus

(c)  the volume of water assigned to the access licence account from the account of an access licence of any category other than regulated river (general security) during that water year, minus

(d)  the volume of water assigned from the Take subaccount of the access licence to the Take subaccount of another access licence.

(2)  The sum of the volume of water allocations held in the Take subaccount of a regulated river (general security) access licence plus the volume of water allocations in the Hold subaccount of the access licence may not, at any time, exceed 2 ML per unit share of the access licence share component.

55 Carryover rules for water allocation accounts

(1)  Water allocations remaining in the accounts of domestic and stock access licences, local water utility access licences, regulated river (conveyance) access licences and regulated river (high security) access licences cannot be carried over from one water year to the next.

(2)  Subject to subclauses (3) and (4), water allocations remaining in accounts of regulated river (general security) access licences may be carried over from one water year to the next.

(3)  If the water allocations are carried over under subclause (2) and if water allocations in the Take subaccount of a regulated river (general security) access licence are greater than the take limit as specified in clause 54 (1) (a), then a volume of water allocations equal to the volume of exceedance must be moved from the Take subaccount into the Hold subaccount.

(4)  If water allocations are carried over under subclause (2) and if water allocations in the Take subaccount of a regulated river (general security) access licence are less than the take limit as specified in clause 54 (1) (a), a volume of water allocations must be moved from the Hold subaccount to the Take subaccount which is equal to the lesser of:

(a)  the volume of water allocations in the Hold subaccount, and

(b)  the volume which would increase the volume of water allocations in the Take subaccount to the take limit as specified in clause 54 (1) (a).

56 Withdrawals from water allocation accounts for regulated river (high security) access licences, regulated river (general security) access licences and regulated river (conveyance) access licences

All water allocations in water allocation accounts of regulated river (general security) access licences, the Spillable subaccounts of regulated river (high security) access licences and regulated river (conveyance) access licences must be withdrawn whenever:

(a)  a spill of water occurs from Wyangala Dam, or

(b)  the Minister deems that a spill of water has occurred from Wyangala Dam, or

(c)  water is released to create or maintain air space at Wyangala Dam, or

(d)  Lake Brewster and Lake Cargelligo are full, deemed by the Minister to be full, or the Minister is satisfied that they will fill from flows already in this water source or its tributaries.

Notes—

1 The effect of clauses 47 (3), 48 (8) and this clause is that when Wyangala Dam spills or is deemed to have effectively spilled or water is released to create or maintain airspace and Lake Brewster and Lake Cargelligo are full or are deemed to be full or that they will fill, as defined in this clause, all regulated river (general security) access licence accounts and regulated river (conveyance) access licence accounts will be equalised. Water remaining in the Spillable subaccounts of regulated river (high security) access licences must be withdrawn. Water remaining in the AWD subaccounts of regulated river (high security) access licences must remain. Assessments indicate that when Wyangala Dam, Lake Brewster and Lake Cargelligo are full it should be possible for each regulated river (general security) access licence account to hold a maximum 1.36 ML/ unit share component.

2 Airspace requirements at Wyangala Dam are determined in accordance with clause 37.

3 Under this clause, the Minister may from time to time, deem that the full volume of Lake Brewster and Lake Cargelligo is less than their physical full capacity. The reasons for this may include supporting a bird breeding event.

Logbook, in relation to an access licence or water supply work approval, means a written record, kept in hard copy or electronic form, that accurately records all information required to be kept in relation to the access licence or water supply work approval under the rules of this Plan.

replenishment flows are flows provided to unregulated river systems downstream of major headwater dams to address the flow related impacts within those systems caused by dam construction.

reserves are volumes of water put aside in a water storage to allow the supply of future water requirements.

supply capability is defined as the rate at which water can be supplied to a section of a water source after satisfying the environmental water provisions and the requirements for water to satisfy basic landholder rights.

translucent flows are releases made from water storages where some portion of the inflows to the water storage are released coincidentally with their occurrence.

transmission losses are any loss of water volume, through natural influences such as evaporation or seepage, which occurs as water travels down a river.

water storage means a state owned dam, weir or other structure, which is used to regulate and manage river flows in this water source and the water body impounded by this structure.

water supply system includes the water storages and all other factors influencing water supply that are under the control of the Minister.

water use development includes all privately owned water management structures, and all aspects of farm, industry, town or private household development which affect the volumes of water taken from the water source, and the management practices that are applied in relation to them, not taking into account the maximum crop area and crop planting behaviour.

Year 5 of this Plan means from the date of 1 July 2020 to 30 June 2021.
