Part 2 Vision, objectives, strategies and performance indicators
9   Vision, objectives, strategies and performance indicators
This Part is made in accordance with section 35 (1) of the Act.
10   Vision
(1)  The vision for this Plan is to achieve a healthy, diverse and productive regulated river water source providing sustainable management of the water source for the community, environment, towns, agriculture and industry.
(2)  This Plan also recognises the following respect statement for Aboriginal values in the regulated river water source:
Life giving water is of extreme significance to Aboriginal culture for its domestic, traditional and spiritual values. Whilst water supplied for the environment will provide protection for native flora and fauna, fishing, food gathering and recreational activities, it is important that the community respects the spiritual significance of water to the Aboriginal people.
11   Objectives
The objectives of this Plan are to:
(a)  protect the natural seasonal variation of low flows during dry periods,
(b)  protect the initial flow in natural freshes,
(c)  protect a high proportion of moderate and high flows,
(d)  protect a high proportion of the natural inundation pattern and distribution of floodwaters supporting natural wetland and floodplain ecosystems,
(e)  mimic natural flow variability of medium and high flows,
(f)  maintain rates of rise and fall river heights within their natural bounds for medium and high flows,
(g)  provide a reserve of water that can be used to assist in management of environmental contingencies,
(h)  contribute to maintenance of estuarine processes and habitats,
(i)  contribute to maintenance of the ecological condition of this water source and its riparian areas over the longer term,
(j)  mitigate the impacts of instream structures,
(k)  mitigate downstream water quality impacts of storage releases,
(l)  maintain water supply priority for basic rights for domestic and stock access licences at all times,
(m)  maintain a highly reliable supply of water to towns to meet the existing and potential population needs of urban communities,
(n)  provide clarity of rights of access to water for the major utility,
(o)  maintain a highly reliable supply water to the major utility access licence,
(p)  provide clarity of rights for holders of regulated river (high security) access licences,
(q)  provide a defined level of water supply access to the irrigation industry,
(r)  provide clarity of access to supplementary water,
(s)  contribute to protection of recreational and tourism opportunities, and
(t)  recognise priority for traditional water rights of Aboriginal people.
12   Strategies
The strategies for reaching the objectives set out in clause 11 are to:
(a)  establish environmental water provisions (Part 3 of this Plan),
(b)  identify water requirements for basic landholder rights (Part 4 of this Plan),
(c)  identify water requirements for access licences (Part 6 of this Plan),
(d)  establish rules for granting of access licences (Part 7 of this Plan),
(e)  establish provisions that place limits on the availability of water (Part 8 of this Plan),
(f)  establish rules for making available water determinations (Part 8 of this Plan),
(g)  establish rules for the operation of water accounts (Part 9 of this Plan),
(h)  establish provisions specifying circumstances under which water may be extracted (Part 9 of this Plan), and
(i)  establish access licence dealing rules (Part 10 of this Plan).
13   Performance indicators
The following indicators are to be used to determine the performance of this Plan against its objectives:
(a)  change in ecological condition of this water source and dependent ecosystems,
(b)  change in low flow regime,
(c)  change in moderate to high flow,
(d)  change in water quality in this water source,

(g)  change in economic benefits derived from water extraction and use,
(h)  extent of recognition of spiritual, social and customary values of water to Aboriginal people, and
(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
14   Environmental water provisions
This Part is made in accordance with sections 5 (3), 8 (1), 8 (2) and 20 (1) (a) of the Act.
15   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 32 of this Plan may not be taken from this water source and used for any purpose,
(b)  water availability is to be managed as specified in clause 34 of this Plan to ensure water volume in excess of the long-term extraction limit is not being taken,
Note—
By limiting long-term extractions to 217,000 Megalitres per year, this Plan ensures that approximately 80% of long-term average flow in this water source (estimated to be 1,040,000 megalitres per year) will be preserved and will contribute to the maintenance of basic ecosystem health.
(c)  this water source shall be managed to ensure that flows, in megalitres per day (hereafter ML/day), exceed those listed in the following table:
Flow reference site
December to February
March to May
June to August
September to November
1. (Liddell)
17 ML/day
18 ML/day
56 ML/day
38 ML/day
3. (Greta)
36 ML/day
40 ML/day
73 ML/day
61 ML/day
and,
(d)  sufficient volumes of water are to be held in reserve in storage to ensure these flows can be provided through a repeat of the worst period of low inflows into this water source (based on historical flow information held by the Department when this Plan commenced).
cl 15: Am 2014 No 48, Sch 2.4 [1].
16   Planned environmental water
(1)  This Plan establishes the following planned environmental water rules for the management of an environmental contingency allowance:
(a)  at the start of each water year a total of 20,000 megalitres in Glenbawn and Glennies Creek water storages is to be reserved in an environmental contingency allowance account for release as specified in subclause (b),
(b)  releases of water from the environmental contingency allowance account are to be made in accordance with procedures established by the Minister to assist in management of critical environmental events, such as algal blooms and chemical spills, and to provide flows at critical times for purposes such as fish migration or stony bed scouring,
(c)  the volume of releases under subclause (b) debited to the environmental contingency allowance account is to be the volume of releases in excess of those necessary to meet all other water requirements, and
(d)  any volume remaining in the environmental contingency allowance account at the end of a water year is to be forfeited from the account.
(2)  This Plan establishes the following planned environmental water rule in relation to periods when access to uncontrolled flows is declared under clause 50 or supplementary water access licences are permitted to extract water under clause 51:
(a)  50% of the daily flow in each river reach defined in Schedule 3 is to be protected during periods when access to uncontrolled flows or access under supplementary water access licences is declared.
Note—
In addition to these rules, there are significant restrictions on the proportion of flow that can be taken during each water year and when extractions under supplementary water access licences can occur (see Part 8 Division 2 and Part 9 Division 2 of the Act). These rules do not meet the Act’s definition of planned environmental water, because they do not “commit” water to the environment as they do not prevent use of these flows to supply water allocated to access licences, other than supplementary water access licences. Nevertheless, they will result in the protection of a major proportion of medium to high flows for the environment and ensure that these flows pass through this water source into the Hunter estuary. It is anticipated that, in all but the most exceptional years, at least 70% of total annual flows in this water source in excess of the 40th percentile flow level will pass through to the estuary.
17   Adaptive environmental water
(1)  At any time an access licence holder can, 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
18   Basic landholder rights
This Part is made in accordance with sections 5 (3) and 20 (1) (b) of the Act.
19   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)  It is estimated that at the time of commencement of Part 2 of Chapter 3 of the Act, the water requirements of holders of domestic and stock rights will total 5,515 megalitres per year (hereafter ML/year) and that these will be distributed between the management zones defined in Schedule 3 in the following way:
(a)  2,592 ML/year in management zone 1,
(b)  2,375 ML/year in management zone 2, and
(c)  548 ML/year in management zone 3.
(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 into this water source (based on historical flow information held by the Department when this Plan commenced).
(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 Glenbawn Dam and Glennies Creek Dam water storages.
Note—
The Minister may issue an order under section 328 of the Act to restrict the exercise of domestic and stock rights from this water source to protect the environment, for reasons of public health, or to preserve basic landholder rights.
cl 19: Am 2014 No 48, Sch 2.4 [2].
20   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 the exercise of native title rights may increase during the term of this Plan.
Note—
Increases in native title rights may occur as a result of granting of native title rights under the Commonwealth’s 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 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 this water source and in reserves held in Glenbawn Dam and Glennies Creek Dam water storages.
Part 5 Bulk access regime
21   Bulk access regime

Part 8 Limits to the availability of water
Division 1 Long-term extraction limit
31   Limit to the availability of water
This Division is made in accordance with section 20 (2) (a) of the Act.
32   Volume of the long-term extraction limit
(1)  This Plan establishes a long-term extraction limit for this water source of an average of 217,000 ML/year.
Note—
The long-term extraction limit established by this Plan is sufficient to allow water extractions to grow by 30% above their current level, and full use of all access licences referred to in Part 6. Should there be a demand for greater volumes of water to service industry or agriculture in the future, the Plan limit may be reviewed. However, any increase would only occur after an assessment of the various ways in which additional water supply could be provided and full consideration of potential environmental effects socio-economic benefits and the impacts, if any, on the rights under existing access licences.
(2)  At the end of each water year the Minister may, under section 45 (1) (b) of the Act alter the volume referred to in subclause (1) as a result of any access licence dealing under section 71R of the Act during that water year.
(3)  For the purposes of auditing compliance with the long-term extraction limit, the following will be included:
(a)  all water extractions under all categories of access licences,
(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)  assignment of water allocations 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 auditing compliance with the long-term extraction limit 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.
33   Assessment of current long-term average annual extraction
(1)  Assessment of 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 Minister for assessing long-term water extraction from this water source.
(2)  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.
34   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 32.
(2)  Pursuant to subclause (1), the maximum total allocation provided by available water determinations in any water year in respect of supplementary water access licences, and if necessary, regulated river (general security) access licences shall be reduced if:
(a)  it has been assessed that the current long-term average annual water extraction from this water source exceeds the long-term extraction limit specified in clause 32 by 3%, or
(b)  assessments in accordance with clause 33 for 3 consecutive years indicate that the current long-term average annual extraction from this water source exceeds 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.
(4)  The first reduction method used under subclause (2) shall be to reduce the water volumes made available to supplementary water access licences by reducing the value of “A” applied to calculations under clause 40 (4).
(5)  Once no extractions under supplementary water access licences are allowed as a result of sub-clause (4), then the limit to the sum of allocations made to regulated river (general security) access licences specified in clause 39 shall be reduced.
(6)  If the total volume of water made available in any water year has been reduced as a result of subclause (2), and a subsequent assessment of extractions performed under clause 33 indicates that 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 extractions to the long-term extraction limit.
(7)  Any reversal of previous reductions shall:
(a)  first be applied to regulated river (general security) access licences, and
(b)  not exceed the previous reductions made under subclause (2).
(8)  The assessment of the degree of reduction required under subclause (2) or degree of reversal under subclause (6) shall be made using the same computer model used to carry out assessments of extractions compared to the long-term extraction limit under clause 33.

Comments
Target 1c Long term average annual extraction limits which are ecologically sustainable and which minimise downstream impacts, established in all coastal catchments.
PARTIAL
  An extraction limit is included in this Plan.
  There is scope for some growth in extractions however the limit would ensure that a high percentage of flows will be protected for environment when compared to most other developed regulated rivers in the State.
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
  This Plan sets minimum flow levels and sets aside water to help manage critical environmental events.
  The extraction rules for supplementary water access licences and the Plan limit should also substantially protect current wetland and estuary inflows.
Target 4a Where the frequency of “end of system” daily flows would be less than 60 percent of the predevelopment level without environmental water rules or extraction limits, the flows increased to 60 percent of predevelopment levels or increased by at least 10 percent of the predevelopment frequency.
FULL
  Frequency of flows are greater than 60% across whole of flow range.
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.
HIGH
  Frequency of flows below natural 95th percentile increased.
Target 5 Access rights for water access licensees clearly and legally specified in terms of share and extraction components.
FULL
  Access for regulated supply licences and supplementary water access licences are specified and tradeable.
Target 9a Flow thresholds for declaration of supplementary water access, which take into account environmental needs, clearly specified.
HIGH
  The initial 12 hours of flows are protected and thresholds are applied to subsequent extractions.
  These thresholds may not however be sufficient to cater for all environmental needs.
Target 9b Annual limits on supplementary water extractions, consistent with the long-term average annual extraction limits, established in all regulated river water sources.
FULL
  This Plan’s rules provide a formula for determining a maximum annual extraction volume for supplementary access licences each year and for formula adjustment should this Plan’s limit be exceeded.
Target 9c Rules for sharing between supplementary water licence holders made explicit.
HIGH
  This Plan ensures that at least 50% of flows in a reach must pass into the next downstream reach.

PARTIAL
  This Plan does not address specific Aboriginal cultural or traditional requirements and has not identified any sites of particular importance.
  The application of a long-term extraction limit that protects a substantial portion of river flows, and this Plan’s environmental flow and supplementary water access rules should provide some protection.
Target 16a All share components of access licences tradeable.
FULL
  All entitlements (including supplementary water) will be tradeable under this Plan.
Target 16c Conversion factors and protocols established to facilitate trading and dealings between water sources, whilst also protecting existing access and environmental water.

Appendix 2 Hunter Water Management Area
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 Sustainable Natural Resources 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.
