Part 2 Vision, objectives, strategies and performance indicators

8 Vision, objectives, strategies and performance indicators

This Part is made in accordance with section 35 (1) of the Act.

9 Vision

The vision for this Plan is to achieve a healthy Lachlan River that provides a dynamic and sustainable environment for native plants and animals, that is enjoyed and valued by the community and that is managed for the socio-economic interest of the people of the Lachlan catchment.

10 Objectives

The objectives of this Plan are to:

(a)  maintain or restore the key environmental features of the Lachlan River system by a river flow regime that, as much as possible, mimics natural conditions in order to make provision for the following outcomes:

(i)  a diversity of natural in-stream and riparian habitat and biota,

(ii)  the restoration, by naturally triggered flooding, of the riverine floodplain to its previous rich mosaic of ecosystems,

(iii)  the improved health and function of wetlands as frequency and duration of inundation is restored,

(iv)  an abundance and diversity of native aquatic species,

(v)  an abundance and diversity of native water birds,

(vi)  the restoration of water quality that supports aquatic ecosystems, and

(vii)  the recovery of threatened species, communities and populations,

(b)  make provisions for access for extraction by towns, riparian landholders, irrigation and other industry for the benefit of rural communities in the Lachlan River system by providing for the following outcomes:

(i)  a supply of water to provide for the needs of rural communities,

(ii)  the specification and provision of basic landholder rights,

(iii)  a water allocation system, which clarifies resource access, and enables flexibility and efficiency within climatic variability, and

(iv)  the maintenance and enhancement of recreational opportunities based on water features,

(c)  provide water to ensure that the social needs and amenity values of the Lachlan Valley community, that are reliant upon water, continue to be met by providing for the following outcomes:

(i)  extent to which native title rights have been met.

Note—

Appendix 4 details the objectives to which these performance indicators relate and the methods for assessing indicators.

Part 3 Environmental water provisions

13 Environmental water provisions

This Part is made in accordance with sections 5 (3), 8 (1), 8 (2) and 20 (1) (a) of the Act.

14 Planned environmental water

This Plan establishes the following planned environmental water rules:

(a)  water volume in excess of the long-term extraction limit established in clause 31 of this Plan may not be taken from this water source and used for any purpose, and

(b)  water availability is to be managed as specified in clause 33 of this Plan to ensure water volume in excess of the long-term extraction limit is not being taken.

Note—

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

15 Planned environmental water

(1)  This Plan establishes the following planned environmental water rules for the management of translucent releases from Wyangala Dam water storage:

(a)  translucent releases may be made from Wyangala Dam during the period 15 May to 15 November, only if the inflows to Wyangala Dam water storage since 1 January that calendar year have exceeded 250,000 megalitres,

(b)  translucent releases under subclause (1) (a) are to be made when the combination of Wyangala Dam inflows plus downstream tributary inflows would be sufficient to produce a flow downstream of Lake Brewster of greater than:

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

(ii)  3,500 ML/day when the volume of water held in Wyangala Dam water storage is more than 50% of the full supply volume,

(c)  the translucent release from Wyangala Dam is to be the lesser of the inflow to Wyangala Dam water storage and the release necessary to achieve a flow at Lake Brewster Weir of :

(i)  4,000 ML/day plus 25 ML/day for each 1% by which the volume of water held in Wyangala Dam water storage 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,

(ii)  3,500 ML/day plus 31.25 ML/day for each 1% by which the volume of water held in Wyangala Dam water storage 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 water storage exceeds 80% of the full supply volume,

Note—

Subclause (1) (c) (iii) results in the maximum release from Wyangala Dam when it is full being the release necessary to achieve a flow at Lake Brewster Weir of 8000 ML/day.

(d)  translucent releases under subclause (1) (a) are only to be made when the sum of flows that have passed downstream of Lake Brewster Weir (measured at Brewster Weir) since the 1 June of that year are less than 350,000 megalitres plus the sum of the following over the same period:

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

(ii)  replenishment flows to effluent rivers downstream of Lake Brewster Weir and any losses downstream of Lake Brewster Weir associated with delivery of these replenishment flows,

(iii)  any flow volume downstream of Lake Brewster Weir resulting from airspace releases under clause 65, and

(iv)  any flow volume downstream of Lake Brewster Weir resulting from releases made pursuant to 15 (2) (c) or 15 (3) (c),

(e)  tributary inflows occurring at any time that the translucent releases conditions under subclauses (1) (a), (1) (b) and (1) (d) are satisfied are not to be used for extractive purposes or diverted to, or stored in, any weirs or water storages except to the extent that they are in excess of the flow required to satisfy the flow rate downstream of Lake Brewster that results from the calculation in subclause (1) (b),

Note—

If flows are insufficient to satisfy subclause (1) (b), or the conditions specified in subclauses (a) or (d) are not met, tributary inflows may be diverted and stored in Lake Cargelligo or Lake Brewster, consistent with normal operational management.

(f)  water flows required to meet translucent release flow targets in subclause (1) (c) are not to be taken or used for any other purpose,

(g)  releases of water from Lake Cargelligo and Lake Brewster may be substituted for all or part of the translucent releases from Wyangala Dam specified in this clause if making the translucent releases from Wyangala Dam is likely to cause flooding,

(h)  water released in accordance with subclause (1) (g) from Lake Brewster shall be accounted for as flow passing downstream of Lake Brewster Weir under subclause (1) (d), and

(i)  in the event that the release capacity of Wyangala Dam is insufficient to provide the release as specified in subclause (1) (c) plus the releases required to satisfy access licence orders, then:

(i)  releases are to equal the release capacity,

(ii)  water is to be permitted to be taken in accordance with access licence water orders,

(iii)  the portion of the required translucent release which has not been supplied is to be calculated as the total release minus the release made to satisfy access licence holder demands,

(iv)  the volumes calculated under subclause (1) (i) (iii) are to be accrued and released at the earliest opportunity, and

(v)  releases under subclause (1) (i) (iv) are not to be subject to the requirements of subclauses (1) (a), (1) (b) and (1) (c).

(j)  a review of the requirement, in subclause (1) (a), that inflows to Wyangala Dam water storage since 1 January in a calendar year must have exceeded 250,000 megalitres before translucent releases may be made, is to :

(i)  be carried out by the Minister before the end of year 5 of this Plan, and

(ii)  assess the environmental and socio-economic impacts of reductions in the required volume of inflow, and

(k)  subclause (1) (a) may be varied under section 45 (1) (b) of the Act and as set out in Part 14 of this Plan.

(2)  This Plan establishes the following planned environmental water rules for the management of an environmental contingency allowance held in Wyangala Dam water storage (hereafter the WECA) and management of an environmental contingency allowance held in Lake Brewster (hereafter the LBECA):

(a)  accounts of the water credited to and released from the WECA and LBECA are to be kept,

(b)  10,000 megalitres is to be credited to the WECA account and 10,000 megalitres is to be credited to the LBECA account:

(i)  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

(ii)  if no crediting under subclause (2) (b) (i) occurred on 1 July of that water year, 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,

(c)  water credited to the WECA and LBECA accounts may be released for ecological purposes, including, but not limited to, completion of waterbird breeding events, promotion of fish breeding, promotion of fish passage, wetland watering and increasing flow variability,

(d)  rules determining the volume and timing of releases of water credited to the WECA and LBECA accounts shall be specified in accordance with procedures established by the Minister,

(e)  the volume of LBECA available for release from Lake Brewster at any time shall be the lesser of the volume of credit remaining in the LBECA account and the active storage in Lake Brewster, and

(f)  any credits remaining in the WECA and LBECA accounts are to be forfeited at the end of each water year.

Note—

It is not possible to forecast when releases of water from the WECA and LBECA will be required, as releases occur in response to unpredictable environmental circumstances. To allow estimation of the effect of the WECA and LBECA rules on water extractions computer modelling has assumed that a total of 5,000 megalitres of WECA and of LBECA were released at the end of each years 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.

(3)  This Plan establishes the following planned environmental water rules for the management of a water quality allowance (hereafter the WQA):

(a)  an account of the water credited to and released from the WQA is to be kept,

(b)  20,000 megalitres is to be credited to the WQA account on 1 July each year,

(c)  water credited to the WQA may be released for any water quality management purpose, but in particular for reduction of salinity levels and mitigation of blue-green algae impacts,

(d)  rules determining the volume and timing of releases of water credited to the WQA account shall be specified in accordance with procedures established by the Minister, and

(e)  any credits remaining in the WQA accounts are to forfeit at the end of each water year.

16 Adaptive environmental water

(1)  At any time an access licence holder may, by a process determined by the Minister, commit all or part of their licence as adaptive environmental water.

(2)  The Minister may grant an access licence in a water source to which this Plan applies if the licence is subject to an adaptive environmental water condition and arises through water savings in the system made in that water source as referred to in section 8C (1) of the Act.

(2A)  The Minister may change the category or subcategory of an access licence in a water source to which this Plan applies if the licence is subject to an adaptive environmental water condition that arises through water savings as referred to in section 8D of the Act.

(3)  At the commencement of this Plan there are no access licences committed to an environmental purpose in accordance with section 8 (1) (c) of the Act.

Part 4 Basic landholder rights

17 Basic landholder rights

This Part is made in accordance with sections 5 (3) and 20 (1) (b) of the Act.

18 Domestic and stock rights

Note—

Water from this water source should not be consumed without prior treatment, which is adequate to ensure its safety.

(1)  At the commencement of this Plan the water requirements of holders of domestic and stock rights are estimated to be 4,211 megalitres per year (hereafter ML/year).

(2)  This Plan recognises that the exercise of domestic and stock rights may increase during the term of this Plan.

Note—

Increase in use of domestic and stock rights may occur as a result of an increase in the number of landholdings fronting this water source or as a result of an increase in the exercise of domestic and stock rights on existing landholdings.

(3)  The water supply system shall be managed so that it would be capable of maintaining supply to those exercising domestic and stock rights through a repeat of the worst period of low inflows to this water source, as represented in flow information held by the Department.

(4)  To achieve subclause (3), sufficient volumes of water must be set aside from assured inflows into the water source and in reserves held in Wyangala Dam water storage or other water storages.

Note—

The Minister may issue an order under section 328 of the Act to restrict the exercise of domestic and stock basic rights from the water source to protect the environment, for reasons of public health, or to preserve basic landholder rights.

19 Native title rights

Note—

Water from this water source should not be consumed without prior treatment, which is adequate to ensure its safety.

(1)  At the commencement of this Plan there are no holders of native title rights in this water source and therefore native title rights are 0 ML/year.

(2)  This Plan recognises that native title rights may increase during the term of this Plan.

Note—

Increase in native title rights may occur as a result of the granting of native title rights under the Commonwealth Native Titles Act 1993.

(3)  The water supply system shall be managed so that it would be capable of maintaining supply to those exercising native title rights through a repeat of the worst period of low inflows to this water source represented in flow information held by the Department

(4)  To achieve subclause (3), sufficient volumes of water must be set aside from assured inflows into the water source and reserves held in Wyangala Dam water storage or other water storages.

Part 5 Bulk access regime

20 Bulk access regime

(1)  This Part is made in accordance with section 20 (1) (e) of the Act.

Part 6 Requirements for water under access licences

21 Requirements for water under access licences

This Part is made in accordance with section 20 (1) (c) of the Act.

Note—

The following clauses in this Part represent the total volumes specified in the share components of access licences in this water source. There is no commitment to make these volumes available. The actual volumes available at any time will depend on climate, access licence priority and the rules in this Plan.

22 Share component of domestic and stock access licences

It is estimated that at the time of commencement of Part 2 of Chapter 3 of the Act, the share components of domestic and stock access licences authorised to extract water from this water source will total 13,100 megalitres per year.

cll 22–26: Subst 1.7.2004.

26 Share component of regulated river (conveyance) access licences

It is estimated that at the time of commencement of Part 2 of Chapter 3 of the Act, the share components of regulated river (general security) access licences authorised to extract water from this water source will total 17,911 unit shares.

cll 22–26: Subst 1.7.2004.

27 Share component of supplementary water access licences

There shall be no supplementary water access licences authorised to extract water from this water source.

28 Changes to total share component

This Plan recognises that total requirements for water under access licences in each access licence category may change during the term of this Plan as a result of:

(a)  the granting, surrender, cancellation or non renewal of access licences, or

(b)  variations to local water utility access licences arising from section 66 of the Act.

Part 7 Rules for granting access licences

29 Rules for granting access licences

(1)  This Part is made in accordance with section 20 (2) (b) and 63 of the Act.

(2)  Access licences may be granted in this water source, subject to any embargo on the making of applications for access licences made under Chapter 3 Part 2 Division 7 of the Act.

Part 8 Limits to the availability of water

Division 1 Long-term extraction limit

30 Limit to the availability of water

This Division is made in accordance with section 20 (2) (a) of the Act.

31 Volume of the long-term extraction limit

(1)  This Plan establishes a long-term extraction limit for this water source which is the lesser of:

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

(i)  the water storages, private water management infrastructure, cropping mix that existed in 1999/2000,

(ii)  the share components existing at the time of commencement of this Plan,

(iii)  the maximum crop area and the crop planting behaviour adopted as representative of baseline conditions used for assessment of Cap under Schedule F of the Murray Darling Basin Agreement, and

(iv)  application of the water management rules defined in this Plan, or

(b)  the long-term average annual extraction from this water source that would occur under the baseline conditions used for assessment of the Cap under Schedule F of the Murray Darling Basin Agreement.

Note—

The baseline conditions used for assessment of the Cap under Schedule F of the Murray Darling Basin Agreement means the level of water resource development at June 1994.

Note—

An estimate of the long-term average annual extraction that would occur under the conditions specified under subclause (1) (a) has been made by the Department using the Lachlan IQQM computer model scenario run number E229. This indicated a long-term average annual extraction volume of approximately 305,000 megalitres.

Note—

An assessment of the long-term average annual extractions that would result from the baseline conditions in subclause (b) has been made using the Lachlan IQQM computer model scenario run number C071A. This indicated a long-term average annual extraction volume of approximately 315,000 megalitres.

Note—

The long-term extraction limit recognises the effect of climatic variability on the availability of water, in accordance with section 20 (2) (c) of the Act, as historic climate and river flow information is used in its determination.

(2)  The values referred to in subclauses (1) (a) and (1) (b) shall be adjusted for any access licence dealings under section 71R of the Act.

(3)  For the purposes of establishing the long-term extraction limit and auditing compliance with it, the following shall be included:

(a)  all water extractions by holders of all categories of access licences in accordance with the rules used for accounting of Cap diversions for Schedule F of the Murray Darling Basin Agreement,

(b)  domestic and stock rights and native title rights extractions,

(c)  volumes of water delivered as adaptive environmental water,

(d)  floodplain harvesting extractions determined to be taken for use in conjunction with extractions from this water source, and

(e)  water allocations assigned from the water allocation accounts of access licences in this water source to the water allocation accounts of access licences in other water sources.

(4)  For the purposes of establishing the long-term extraction limit and auditing compliance with it,

(a)  the assessed volume of extractions shall be reduced by the volume of water allocations being assigned from the water allocation accounts of access licences in any other water source to the water allocation accounts of access licences in this water source, and

(b)  the following shall not be included:

(i)  replenishment flows made in accordance with this Plan, or

(ii)  diversion of water pursuant to the planned environmental water rules in Part 3 of this Plan.

32 Assessment of the long-term extraction limit and current long-term average annual extraction

(1)  Assessment of the long-term extraction limit and the current long-term average annual extraction shall be carried out 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.

(2)  To assess the long-term extraction limit, the model referred to in subclause (1) shall be set to represent as closely as possible the conditions referred to in clauses 31 (1) (a) and 31 (1) (b).

(3)  To assess the current long-term average annual extraction from this water source, the model referred to in subclause (1) shall 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 water extraction from this water source at the time of the assessment.

(4)  Any advice provided by the Compliance Assessment Advisory Committee, if one has been established under clause 34, should be considered in relation to assessments under subclause (1).

33 Maintaining compliance with the long-term extraction limit

(1)  The long-term average annual extraction from this water source shall not be permitted to exceed the long-term extraction limit specified in clause 31.

(2)  Pursuant to subclause (1), the maximum volume that may be taken under a regulated river (general security) access licences during any water year shall be reduced, by reducing the value of X referred to in clause 35, if:

(a)  it has been assessed that the current long-term average annual water extraction from the water source exceeds the long-term extraction limit specified in clause 31 (1) by:

(i)  3% of the long-term extraction limit specified in clause 31 (1), or

(ii)  half the difference between the volume specified in clause 31 (1) (a) and the volume specified in clause 31 (1) (b), or

(b)  it has been assessed that the current long-term average annual water extraction from the water source exceeds the volume specified in clause 31 (1) (b), or

(c)  assessments in accordance with clause 32 for 3 consecutive water years indicate that the current long-term average annual water extraction from the water source exceed the long-term extraction limit.

(3)  The degree of reduction under subclause (2) shall be the degree that is assessed necessary to return the long-term average annual extraction from this water source to the long-term extraction limit.

cll 44: Subst 1.7.2004.

45 Volume taken under access licences

Note—

Section 341 of the Act makes it unlawful to take a volume of water under an access licence that exceeds the volume of water allocation which is credited to the access licence at the time of water extraction.

(1)  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 shall be assessed as:

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

(b)  the greater of

(i)  the volume of water extracted by the approved water supply works nominated by the access licence, or

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

where the Minister has applied such a discretionary condition to the access licence.

(2)  The Minister should only apply a discretionary condition in relation to subclause (1) (b) where this has been provided for in a compliance management strategy approved by the Minister.

Note—

It is intended that the discretionary condition referred to above should only be applied where water orders have been exceeding the volume of water being taken under a licence and this cannot be explained by rainfall or other unavoidable factors.

(3)  The water allocations taken under a regulated river (general security) access licences are to be debited to the A sub-account of the access licence.

cl 45: Am 1.7.2004.

46 Accounting of assigned water allocations and return flows

(3)  Water allocations assigned from the B sub-account of a regulated river (general security) access licence to another regulated river (general security) access licence shall be credited to the B sub-account of the receiving access licence.

(4)  Water allocations assigned to a regulated river (general security) access licence from the account of an access licence of any category which is not permitted to carry over water allocation credits shall be credited to the A sub-account of the access licence.

(5)  Water allocations may also be recredited to access licence water allocation accounts under section 76 of the Act, in accordance with water return flow rules established under section 75 of the Act.

(6)  Unless otherwise specified in the water return flow rules established under section 75 of the Act, water allocations recredited to regulated river (general security) access licences under subclause 5 shall:

(a)  be recredited to the A sub-account of the access licence where re-crediting occurs in the water year in which the allocations were used, or

(b)  shall be recredited to the B sub-account of the access licence where re-crediting occurs in a water year subsequent to that in which the allocations were used.

47 Carrying over of water allocation credits, water allocation account limits and withdrawal of water allocations

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

(2)  Water allocation remaining in the water allocation accounts of regulated river (general security) access licences may be carried over from one water year to the next.

(3)  If water allocations are carried over under sub-clause (2) and if water allocations in the A sub-account of a regulated river (general security) access licence are in excess of X multiplied by the number of unit shares in the share component of the access licence, where X is as determined under clause 35 (1), then a volume of water allocations equal to the volume of exceedance shall be moved from the A sub-account into the B sub-account.

(4)  If water allocations are carried over under sub-clause (2) and if water allocations in the A sub-account of a regulated river (general security) access licence are less than X multiplied by the number of unit shares in the share component of the access licence, where X is as determined under clause 35 (1), then a volume of water allocations shall be moved from the B sub-account to the A sub-account which is equal to the lesser of :

(a)  the volume of water allocations in the B sub-account, and

(b)  the volume which would increase the volume of water allocations in the A sub-account to X multiplied by the number of unit shares in the share component of the access licence, where X is as specified in clause 35 (1).

(5)  The sum of the volume of water allocations held in the A sub-account of a regulated river (general security) access licence plus the volume of water allocations held in the B sub-account of the access licence may not, at any time, exceed 2 megalitres per unit share of the access licence share component.

(6)  The following rules apply to the management of water allocations in the water allocation accounts of regulated river (conveyance) access licences:

(a)  water allocations remaining in the water allocation account at the end of the 2011/12 water year may be carried over to the 2012/13 water year only, and

(b)  the maximum volume that may be held in the water allocation account at any time is 2 megalitres per unit share.

(7)  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,

and Lake Brewster and Lake Cargelligo are:

(d)  full, or

(e)  deemed by the Minister to be full, or

(f)  the Minister is satisfied they will fill from flows already in this water source or its tributaries,

then all water allocations remaining in the water allocation accounts of regulated river (general security) access licences shall be withdrawn.

Note 1—

The effect of subclause (7) and clause 40 (2) 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 they will fill, as defined in subclause (7), all general security access licence accounts will be equalised. 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 megalitres per unit share.

Note 2—

Airspace requirements at Wyangala Dam are determined in accordance with clause 65.

Note 3—

Under subclause (7), 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.

(8)  The Minister may, in accordance with clause 69, amend this Plan to replace this subclause with rules relating to carrying over of water allocation credits, water allocation account limits and withdrawal of water allocations for regulated river (conveyance) access licences and may further amend the rules if the Minister considers it necessary to do so to reflect the actual conveyancing losses experienced by Jemalong Irrigation.

Division 3 Extraction conditions

48 General priority of extractions

Where extraction components of access licences do not specify the rate as a share of supply capability or a volume per unit time, the following priority of extractions shall apply whenever supply capability is insufficient to satisfy all orders for water in any section of this water source:

(a)  water shall be supplied to domestic and stock access licences, local water utility access licences and regulated river (high security) access licences that have placed orders for water, and

(b)  then any remaining supply capability shall be shared between regulated river (general security) and regulated river (conveyance) access licences that have placed an order for water, in proportion to share components specified on the access licences.

49 Numerical specification of extraction components

(1)  At any time during the term of this Plan, the Minister may, in accordance with the mandatory conditions on access licences, amend the extraction components of access licences in this water source, or in any section of this water source.

(2)  Action under subclause (1) should be undertaken as follows:

(a)  the specified rate in the extraction component of each access licence should be a volume per unit of time or a share of supply capability,

(b)  the specified rate in the extraction component of each domestic and stock local water utility and regulated river (high security) access licence should be sufficient to satisfy the maximum water needs, and

(c)  after satisfying subclause (b), the remaining supply capability should be distributed among regulated river (general security) access licences and regulated river (conveyance) access licences in proportion to the share component of each access licence.

(3)  When action under subclause (1) is undertaken, the Minister may also, in accordance with mandatory conditions on access licences, amend the extraction components of access licences in other sections of this water source to exclude extractions in sections of this water source affected by the action under subclause (1).

52 Rules for change of water source

(1)  This clause relates to dealings under section 71R of the Act.

Note—

Section 71R dealings are the mechanism by which access licences can move from one water source to another. Once the change in water source has been effected, if permitted, the new licence will have to nominate specified works (by a dealing under section 71W of the Act) in the receiving water source before extraction can commence.

(2)  Access licences in other water sources outside of this water source may be issued following cancellation of access licences in this water source, only if:

(a)  the access licence dealing rules in the receiving water source permit such a dealing,

(b)  a conversion factor, established by the Minister and published in an Order made under section 71Z of the Act that protects environmental water, domestic and stock rights, native title rights and the reliability of supply to all other access licences in this water source, has been applied, and

(c)  the water source in which the access licence is issued is one of the following:

(i)  a water source within the Lachlan Unregulated Extraction Management Unit, (as defined in the Water Sharing Plan for the Mandagery Creek Water Source 2003) , and not on a river that is primarily fed by effluent flows from the Lachlan River, or

Note—

The prohibition on the issue of licences within effluent rivers is included to stop licence trading leading to an increase in extractions from rivers feeding environmentally sensitive wetland areas.

(ii)  a regulated river in the Belubula River catchment.

(3)  Access licences in this water source may be issued following cancellation of access licences in other water sources, only if:

(a)  the access licence dealing rules in the other water source permit such a dealing,

(b)  a conversion factor, established by the Minister and published in an Order made under section 71Z of the Act that protects environmental water, domestic and stock rights, native title rights and the reliability of supply to all other access licences in this water source, has been applied, and

(3)  On application of the access licence holder, the Minister may cancel a regulated river (general security) access licence, and issue a regulated river (high security) access licence, subject to:

(a)  the application of a conversion factor established by the Minister and published in an Order made under section 71L of the Act that protects environmental water, domestic and stock rights, native title rights and the reliability of supply to all other access licences in this water source,

Note—

It has been assessed that a conversion factor of 0.45 should apply to the conversion of the first 30,000 unit shares of regulated river (general security) access licence to regulated river (high security) access licence.

(b)  the number of megalitres of water in the regulated river (general security) access licence water allocation account being equal to or greater than the number of unit shares in its share component, and

(c)  the volume of water allocations credited to the water allocation account of the new regulated river (high security) access licence water allocation account not exceeding the volume of water allocation held in the A sub-account of the cancelled access licence.

Note—

The volume of water in the regulated river (general security) access licence water allocation account which is in excess of the share component volume of the new regulated river (high security) access licence will not be credited to the new regulated river (high security) access licence account.

(4)  On application of the access licence holder, the Minister may cancel a regulated river (high security) access licence, and issue a regulated river (general security) access licence, subject to:

(a)  the application of a conversion factor equal to one divided by the conversion factor established in subclause (3), and

(b)  such an application not resulting in an increase in the total number of unit shares in regulated river (general security) access licence share components above the total number of unit shares at the time of commencement of Part 2 of Chapter 3 of the Act.

Note—

This would allow conversion of a regulated river (high security) access licence to a regulated river (general security) access licence only if there had been a corresponding or larger amount of regulated river (general security) access licence share component converted to regulated river (high security) access licence.

(5)  On application of the licence holder, the Minister may cancel a regulated river (conveyance) access licence and issue a regulated river (general security) access licence and/or a regulated river (high security) access licence, subject to:

Schedule 2 Contribution to relevant targets in the December 2002 State Water Management Outcomes Plan

Levels of assessed contribution:

FULL contributes to target in full

HIGH while not fully contributing to target, there is a good level of contribution

PARTIAL goes some way to contributing to target

LOW only small degree of contribution to target

Relevant Target	Level of contribution	Comments
Target 1a Extractions in Murray Darling Basin’s regulated rivers limited to the level of the long term average annual extraction below the MDBMC Cap which results from the long term impact of the environmental water rules	FULL	•  Plan clearly sets out the basis for the long-term extraction limit
Target 1f Rules for adjustments to future available water determinations in the event that the extraction limits are exceeded, clearly prescribed in consultation with the relevant management committee, and acted upon	FULL	•  Rules set out in Part 8
Target 2 All water management plans incorporating mechanisms to protect and restore aquatic habitats, and the diversity and abundance of native animals and plants, with particular reference to threatened species, populations and communities and key threatening processes.	PARTIAL	•  Silver perch is a listed Threatened Species is thought to still occur in the Lachlan. Improvement in higher flows may assist its spawning and recruitment. •  The flow improvements should provide increased wetland inundation for a number of lower river wetlands eg Booligal, Murrumbidgil, Lake Merrimajeel, Cumbung Swamp and Merrowie. •  An Environmental Contingency Allowance of 20,000 ML is provided. •  The plan substantially reduces environmental water when Wyangala Dam levels are reduced or water available to access licences restricted, irrespective of the environmental needs.
Target 4a Where the frequency of “end of system” daily flows would be less than 60 percent of the predevelopment level without environmental flow rules or extraction limits, the flows increased to 60 percent of predevelopment levels or increased by at least 10 percent of the predevelopment frequency.	PARTIAL	•  The frequency of flows up to the 20th percentile meet the target •  The frequency of flows between the 20th percentile and the 60th percentile do not meet the target. •  The frequency of flows above the 60th percentile meet the target.
Target 4b Frequency of “end of system” daily very low flows (as defined by local field investigation) protected or restored to predevelopment levels to maintain or restore their critical ecological functions, drought refuges and habitat connectivity. In the absence of such local assessments, protection extended up to at least the predevelopment 95th percentile.	FULL	•  This Plan provides for maintenance of flow to end of system at level which is above the natural 95th percentile flow frequency (which is a zero flow)
Target 4c The channel capacity of all lower river and effluent creek systems used for the delivery of regulated water determined. Subject to reasonable socio-economic impacts, limits on daily supply volumes established for effluent systems such that they do not exceed 80 percent of the channel capacity for more than 10 percent of days in each month of each year. Where daily supply volumes are currently substantially less than channel capacity, alternative limits established to reduce the impact of unseasonal flows arising from future access licence dealings.	PARTIAL	•  This Plan provides for the determination of maximum operating channel capacities in accordance with the SWMOP target. •  This Plan also provides for the distribution of numerical extraction rights that could be used to facilitate management to desired capacity targets. •  The Plan also notes a number of maximum channel capacity constraints that would apply at the start of this Plan. However, these are only expressed as a Note and are therefore not part of the Plan.
Target 5 Access rights for water access licensees clearly and legally specified in terms of share and extraction components.	HIGH	•  Access rights are specified and tradeable
Target 12 Measures in place in all water sources subject to a gazetted water sharing plan to protect basic domestic and stock water rights from the impact of other water access and use.	FULL	•  Obligations are set out in Part 5
Target 14 Water sources, ecosystems and sites of cultural or traditional importance to Aboriginal people identified, plans of management prepared, and measures put in place to protect and improve them.	LOW	•  The Plan does not address specific Aboriginal cultural or traditional requirements and has not identified any sites of particular importance. •  It is likely that the environmental flow rules in the Plan will contribute to protection.
Target 16a All share components of access licences tradeable.	PARTIAL	•  All share components are tradeable. •  This Plan prohibits the movement of share component from upstream of Lake Cargelligo Weir to downstream of Lake Cargelligo Weir and vice versa. However it does provide for review and possible removal or modification of this restriction. •  The limits placed on movement of share component and allocation into Willandra Creek and the Lachlan downstream of Booligal have been put in place because of the potential environmental impacts that would result from changes in flow regimes resulting from increased regulated flow.
Target 16c Conversion factors and protocols established to facilitate trading and dealings between water sources, whilst also protecting existing access and environmental water	FULL	•  Assignments between water sources are in line with Government policy
Target 16d Reduced conversion factors only applied when necessary to offset increased losses associated with water supply delivery	FULL	•  The Plan does not impose reduction factors
Target 16f Zones established where necessary for environmental protection and limits/constraints on water dealings in them made explicit.	PARTIAL	•  This Plan establishes dealing zones being upstream and downstream of Cargelligo Weir, downstream of Booligal and Willandra Creek.
Target 35 All management plans incorporating water quality objectives that have considered Government approved Interim Environmental Objectives, the current Australian and New Zealand Environment and Conservation Council Guidelines and the recommendations of relevant Healthy Rivers Commission Inquiries.

Appendix 3 State floodplain harvesting principles

Section 1 Definition and categories of floodplain harvesting

(1)  Floodplain harvesting is the collection, extraction or impoundment of water flowing across floodplains. The floodplain flows can originate from local runoff that has not yet entered the main channel of a river, or from water that has overflowed from the main channel of a river during a flood. For the purposes of this policy the floodplain is defined as extending to the 1 in 100 year flood line.

(2)  Floodplain harvesting can generally be put into one of three categories:

(a)  diversion or capture of floodplain flows using purpose built structures or extraction works to divert water into storages, supply channels or fields or to retain flows,

(b)  capture of floodplain flows originating from outside of irrigated areas using works built for purposes other than floodplain harvesting. Examples are:

(i)  levees and supply works such as off river storages constructed in billabongs or depressions that fill from floodplain flows, and

(ii)  below ground level water channels from which the water is pumped into on farm storages, and

(c)  opportunistic diversions from floodplains, depressions or wetlands using temporary pumps or other means.

Note—

Capture of rainfall or runoff from farm irrigation fields, via tailwater systems or other means, is not floodplain harvesting.

Section 2 Floodplain harvesting management issues

(1)  The harvesting of water from floodplains reduces the amount of water reaching or returning to rivers. This decreases the amount of water available to meet downstream river health, wetland and floodplain needs and the water supply entitlements of other users.

(2)  Floodplain harvesting can seriously affect the connectivity between the local floodplain, wetlands and the river, through the loss of flow volume and redirection of water flows.

(3)  The Water Act 1912 provided powers to license floodplain harvesting. However this was never applied as there was generally no requirement to restrict total overall water extractions or off-allocation diversions. Harvested floodplain water has been treated as a freely available bonus to a farmer’s licensed entitlement.

(4)  This situation has now changed. The Murray-Darling Basin cap applies to all water diverted from inland NSW catchments and rivers. Licensed and off-allocation access has been subject to increasing restrictions. Embargoes on water licences are also in place on many areas on the coast.

(5)  Floodplain harvesting works and water extractions also clearly fall into those activities that the Water Management Act 2000 requires to be only undertaken by way of a licence. The Act also requires such licensing to consider the ecological functioning of floodplains.

(6)  Floodplain harvesting can no longer be left outside of the State’s water management and compliance system or as a source of increase in further water extractions. Given this, it is the Government’s intention that floodplain harvesting works and taking of water from floodplains be licensed and managed. It will take a number of years to complete the process. However, the water sharing plans must signal the basic principles that will govern the process.

Section 3 Management of floodplain harvesting

(1)  Floodplain harvesting will not be a component of individual water sharing plans being produced for the regulated and unregulated rivers. During flood times water originating in one river system may flow across floodplains and along “flood runners” into adjacent river systems. It is therefore often not possible to assign an area of floodplain to a particular river.

(2)  Management of floodplain harvesting will occur on a state-wide basis, according to the six principles set out in section 4.

(3)  There are many thousands of existing floodplain works which will require licensing and this will be done over the next couple of years. The licensing process will include proper environmental impact assessments.

(4)  A separate category of licence will be established.

Section 4 Floodplain harvesting principles

(1)  Principle 1 is that all existing floodplain harvesting works and floodplain harvesting extractions will be licensed.

(2)  Principle 2 is that licensing will focus initially on controlling the structures, but with movement towards specifying volume limits and flow related access conditions, including metering of pumps

Note—

While all surface and groundwater licences now (or will shortly) specify volume entitlements or annual limits to water, it is not possible to do this for floodplain harvesting licences at this stage. This is because the pattern of use is highly episodic and site and infrastructure specific, and current data on structures and use is minimal.

The Department of Land and Water Conservation will licence existing structures and specify monitoring of use (including metering of pumps) as a licence condition where possible. This may not be possible initially in cases where a tailwater system is also picking up floodplain water as they are difficult to separate, or where overland flow is being captured by a billabong for which we do not have any information on its capacity. Options for application of volumetric conditions will be developed and implemented where appropriate within the first five years of the initial water sharing plans.

(3)  Principle 3 is that no new works or expanded floodplain harvesting activities in the Murray-Darling Basin that will result in the diversion of additional water will be authorised.

Note—

All new floodplain harvesting works are required by law to be licensed. However, as any new works would result in a growth in diversion, which would threaten river health and/or the water entitlements of others, such works would have to be offset by a reduction in other forms of water diversion.

(4)  Principle 4 is that floodplain diversions associated with works in place in the Murray-Darling Basin prior to the end of the 1994 irrigation season will be considered as within the NSW cap.

Note—

Because cap is based on the use of water with development as it was in 1994, NSW considers that the water use that would result from use of the floodplain infrastructure in place in 1994, is part of the cap in each system.

(5)  Principle 5 is that once licensing is completed, an assessment of long-term use resulting from authorised structures against that from structures which existed in 1994 will be carried out and appropriate steps taken to keep harvesting to cap levels.

Note—

It is likely that there has been some growth in floodplain harvesting works and extractions since 1994. However, it is expected that the licensing process will result in some modification of existing works. This may be adequate to offset any post 1994 development. If not, restrictions on the use of the licensed works will have to be applied to return diversions to cap levels. Such restrictions could include restrictions on pumping times or a requirement to modify the work to allow a proportion of flows to be bypassed. By preventing the construction or enlargement of new works, the opportunity for any further growth in floodplain harvesting diversions will be minimised.

(6)  Principle 6 is that floodplain harvesting rights will not be tradeable.

Note—

Trading of floodplain harvesting rights will not be permitted because the frequency and volume of use is site and infrastructure specific, and volume management will take some time to implement.
