Part 1 Introduction
Note—
Part 14 allows for amendments to be made to this Part.
1 Name of Plan
This Plan is the Water Sharing Plan for the Gwydir Regulated River Water Source 2016 (hereafter this Plan).
2 Nature and status of this Plan
(1) This Plan is made under section 50 of the Water Management Act 2000 (hereafter the Act).(2) This Plan covers the core provisions of section 20 of the Act for water sharing, and additional provisions of section 21 of the Act, and other relevant matters.
3 Date of commencement
This Plan takes effect on 1 July 2016, and ceases on 30 June 2026.1This Plan replaces the Water Sharing Plan for the Gwydir Regulated River Water Source 2002.2In accordance with section 43 of the Act as it currently stands, this Plan will have effect for 10 years from 1 July 2016. The Minister may extend this Plan for a further period of 10 years after it is due to expire, in accordance with section 43A of the Act.3Under the Intergovernmental Agreement on Implementing Water Reform in the Murray-Darling Basin and the associated National Partnership Agreement, NSW has agreed to develop water resource plans for Murray-Darling Basin water resources that are consistent with the requirements of the Commonwealth’s Basin Plan 2012. The water resource plan for the Gwydir surface water area is currently scheduled to commence on 1 July 2018. In order to make a water resource plan that commences by this date, amendments to the Act may be required to enable this Plan to be replaced prior to the end of its 10-year term.cl 3: Am 2016 No 27, Sch 2.54 [1].
4 Water source and waters to which this Plan applies
(1) The water source in respect of which this Plan is made is that between the banks of all rivers, from Copeton Dam water storage downstream to the junction of the Gwydir River and its effluent rivers with the Barwon River, which, at the date of commencement of the Plan, have been declared by the Minister to be regulated rivers.Note—A regulated river is a river that has been declared by the Minister, by order published in the New South Wales Government Gazette, to be a regulated river.Note—The regulated rivers referred to in subclause (1) are listed in Appendix 1.(2) The water source shall be known as the Gwydir Regulated River Water Source (hereafter this water source).(3) The rivers included in this water source may be varied under section 45 (1) (b) of the Act as set out in Part 14 of this Plan.(4) This water source is within the Gwydir and Border Rivers Water Management Areas constituted by the Ministerial order published in the NSW Government Gazette (hereafter the Gazette) on 23 November 2001.Note—The Gwydir River system is shown on the map in Appendix 2.(5) This Plan applies to all waters contained within this water source but does not apply to waters contained within aquifer water sources underlying these water sources or to water on land adjacent to this water source.Note—Management of floodplain harvesting is not a component of this water sharing plan. Management of floodplain harvesting will occur according to a number of state-wide management principles, attached in Appendix 3.cl 4: Am 2000 No 92, Sch 12, Part 5 (ins 2018 No 31, Sch 1 [89]).

15 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.(3) 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.
Part 4 Basic landholder rights
16 Basic landholder rights
This Part is made in accordance with sections 5 (3) and 20 (1) of the Act.
17 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) As at 1 July 2004 the water requirements of holders of domestic and stock rights are estimated to be 6,000 megalitres per year (hereafter ML/yr).(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 by an increase in the exercise of domestic and stock rights on 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 into this water source (based on historical flow information held by the Department as at 1 July 2004).(4) To achieve subclause (3) sufficient volumes of water must be set aside from assured inflows into the plan area and reserves held in Copeton Dam water storage.Note—The Minister may issue an order under section 328 of the Act to restrict the exercise of domestic and stock basic rights from this water source to protect the environment, for reasons of public health, or to preserve basic landholder rights.
18 Native title rights
Note—Water from this water source should not be consumed without prior treatment which is adequate to ensure its safety.(1) As at 1 July 2004 there were 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 Title 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 these water sources, 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 this water source and in reserves held in Copeton Dam water storage.cl 18: Am 2016 No 27, Sch 2.54 [2].
Part 5 Bulk access regime
19 Bulk access regime
(1) This Part is made in accordance with section 20 (1) (e) of the Act.(2) This Plan establishes a bulk access regime for the extraction of water under access licences in this water source having regard to:(a) the environmental water provisions established under Part 3 of this Plan,(b) the requirements for basic landholder rights identified under Part 4 of this Plan, and(c) the requirements for water for extraction under access licences identified under Part 6 of this Plan.(3) The bulk access regime established under subclause (2):(a) establishes rules according to which access licences are granted as provided for in Part 7 of this Plan,(b) recognises and is consistent with the limits to the availability of water as provided for in Part 8 of this Plan,(c) establishes rules according to which available water determinations are to be made as provided for in Part 8 of this Plan,(d) recognises the effect of climatic variability on the availability of water as provided for in Part 8 of this Plan,(e) establishes rules with respect to the priorities according to which access licences are to be adjusted as a consequence of any reduction of the availability of water as provided for in Part 8 of this Plan, and(f) establishes rules according to which access licences are managed as provided for in Part 9 of this Plan.
Part 6 Requirements for water under access licences
20 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 or unit shares specified in the share components of access licences in this water source. The actual volume of water available at any time will depend on climate, access licence priority and the rules in this Plan.
21 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 totalled 4,245 ML/year.
22 Share component of local water utility access licences
It is estimated that at the time of commencement of Part 2 of Chapter 3 of the Act, the share components of local water utility access licences authorised to extract water from this water source totalled 3,836 ML/year.
23 Share component of regulated river (high security) 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 (high security) access licences authorised to extract water from this water source totalled 19,293 unit shares.
24 Share component of regulated river (general security) 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 totalled 509,500 unit shares.
25 Share component of supplementary water access licences
It is estimated that at the time of commencement of Part 2 of Chapter 3 of the Act, the share components of supplementary water access licences authorised to access water from this water source totalled 178,000 unit shares.
26 Changes to total share component
This Plan recognises that total requirements for extraction 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
27 Rules for granting access licences
(1) This Part is made in accordance with sections 20 (2) (b), 61 and 63 of the Act.(2) Applications may be made for the following access licences in this water source:(a) local water utility access licences,Note—Pursuant to sections 66 (3) and 66 (4) of the Act, the Minister may also vary a local water utility’s share component at 5 yearly intervals, or on application of the local water utility where there is a rapid growth in population.(b) specific purpose access licences for which applications are provided for under the regulations in accordance with section 61 (1) (a) of the Act.(3) Applications may not be made for a regulated river (high security) (Aboriginal cultural) access licence if the proposed access licence is more than 10 ML/year.(4) In applying for a new access licence, the applicant must establish the purpose and circumstances relating to that access licence, and that the share component sought will be the minimum required to meet that purpose and circumstances.(5) Subclause (4) does not apply to an application for a new access licence arising from:(a) section 61 (1) (c), of the Act, where the right has been acquired by auction, tender or other open market process, or(b) an access licence dealing.cl 27: Am 2016 No 27, Sch 2.54 [3].
Part 8 Limits to the availability of water
Division 1 Long-term extraction limit
28 Limit to the availability of water
This Division is made in accordance with section 20 (2) of the Act.
29 Volume of the long-term extraction limit
(1) This Plan establishes a long-term extraction limit for this water source being the lesser of:(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(ii) the share components in this water source that existed on 1 July 2004, and(iii) the rules defined in this Plan as at 1 July 2004, excluding the rules in clause 38, and(iv) the application of a limit on supplementary water access licence available water determinations of 1 megalitre per unit share, or(b) the long-term average annual extraction from this water source that would occur under Cap baseline conditions.Notes—1The rules that were defined in this Plan on 1 July 2004 included a 125% limit to the volume of water that may be taken or assigned from regulated river (general security) access licences in this water source in any water year instead of the 300% limit currently specified in clause 32 (a). Those rules also included a rule that permitted the Minister to suspend or temporarily curtail flows from the Horton River, Myall Creek and Halls Creek if this would be environmentally beneficial to the Gwydir Wetlands. This rule, specified in clause 13 (c)–(f), has been amended to allow the Minister to suspend or temporarily curtail these flows if, in the Minister’s opinion, such an action would not be detrimental to the environmental health of the Gwydir Wetlands.2An assessment of the long-term average annual extraction that would occur under the conditions specified in subclause (1) (a) has been made using the Gwydir IQQM computer model with system file WSP8TST6.SQQ. This indicates a long-term average annual extraction volume of 392,000 megalitres.3An assessment of the long-term average annual extractions resulting from the baseline conditions in subclause (1) (b) has been made using the Gwydir IQQM computer model with system file dv93465a.s6_IQQMV6.61.001. This indicates a long-term average annual extraction volume of 415,000 megalitres.4The 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 dealing 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 all categories of access licences in accordance with the rules used for accounting of Cap diversions for Schedule E of the Murray-Darling Basin Agreement,(b) domestic and stock and native title rights extractions,(c) volumes of water delivered as adaptive environmental water,(d) floodplain harvesting extractions estimated to be taken for use in conjunction with extractions authorised from this water source, and(e) water allocations assigned from access licence water allocation accounts in this water source to access licence water allocation accounts in another water source.(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.
30 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 use 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 29 (1) (a) and 29 (1) (b).(3) To assess 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, supply system management and other factors affecting the quantity of long-term average annual extraction from this water source at the time of compliance assessment.(4) Any advice provided by a Compliance Assessment Advisory Committee if established under clause 31 (9) should be considered in relation to assessments under subclause (1).
31 Compliance with the long-term extraction limit
(1) The long-term average annual extraction from this water source may not be permitted to exceed the long-term extraction limit specified in clause 29.(2) Pursuant to subclause (1):(a) if it has been assessed that the current long-term average annual extraction from this water source, exceeds:(i) the volume specified in clause 29 (1) (a) by 3% or more,(ii) the volume specified in clause 29 (1) (a) by more than half the difference between the volume specified in clause 29 (1) (a) and the volume specified in clause 29 (1) (b), or(iii) the volume specified in clause 29 (1) (b), or(b) if the assessments for 3 consecutive water years indicate that the current long-term average annual extraction from this water source exceeds the long term extraction limit,(c) then the maximum available water determination made for supplementary water access licences under clause 38 shall be reduced, and(d) once the maximum available water determination for supplementary water access licences has reduced to zero, the maximum volumes that may be taken or assigned from a regulated river (general security) access licences under clause 32 shall be reduced.(3) The degree of reduction under subclause (2) shall be that assessed necessary to return long-term average annual extractions to the long-term extraction limit.(4) Reductions in the amounts specified in clauses 32 (a) and 32 (b), pursuant to subclause (3), are to be of the same proportion.Note—Subclause (4) means that if the amount specified in clause 32 (a) is reduced from say 1.25 to 1 (ie by one fifth), then the amount specified in clause 32 (b) is to be reduced from 3 to 2.4 (ie one fifth).(5) If action has been taken under subclause (2), and a subsequent assessment under clause 30 indicates that the current long-term average annual extractions are below the long-term extraction limit by more than 3%, then previous reductions under subclause (2) may be reversed to the degree that it is assessed necessary to return the long-term average annual extractions to the long term extraction limit.(6) Any reversal of previous reductions under subclause (5):(a) shall not exceed previous reductions made under subclause (2), and(b) shall first reverse any previous reductions relating to regulated river (general security) access licences.(7) The assessment of the degree of any reduction required under subclause (2) or degree of any reversal under subclause (5), shall be made using the same computer model used to carry out assessments under clause 30.(8) Any advice provided by a Compliance Assessment Advisory Committee if established under subclause (9) should be considered in relation to assessments under subclauses (2) and (5).(9) Within 6 months of the commencement of the Plan, the Minister should establish a Compliance Assessment Advisory Committee under section 388 of the Act for the purpose of providing advice regarding assessments under clauses 30 and 31.(10) In providing its advice the Compliance Assessment Advisory Committee should consider possible improvements to:(a) the process for assessing current long-term average annual extractions,(b) the computer model referred to in clause 30,(c) the data used in the computer model referred to in clause 30,(d) the assessment of the effect of any actions taken in accordance with subclauses 31 (2) and 31 (5), and(e) remedy any compliance issues encountered through the implementation of the Plan.(11) Membership of the Compliance Assessment Advisory Committee should be for a period of 5 years and should consist of the following:(a) a person representing the Department,(b) a person representing the State Water,(c) a person representing NSW Agriculture,(d) no more than 3 persons representing the irrigation industry,(e) a person representing local government,(f) a person representing the Department of Planning and Environment,(g) a person representing nature conservation interests, and(h) other members as required by the Minister.(12) The Compliance Assessment Advisory Committee is to meet at least annually.
32 Limit to the volumes that may be taken under or assigned from regulated river (general security) access licences
The maximum volume that may be taken under or assigned from a regulated river (general security) access licence in this water source:(a) during any water year, shall be equal to 3 megalitres multiplied by the number of unit shares specified in the share component of the access licence, or such lower amount that may result from clause 31, plus the volume of water allocations assigned to the access licence from another access licence during that water year, and(b) during any 3 consecutive water years, shall be equal to 3.0 megalitres multiplied by the number of unit shares specified in the share component of the access licence, or such lower amount that may result from clause 31, plus the volume of water allocations assigned to the access licence from another access licence during the 3 water years.

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.
