Many members will have received letters in recent weeks regarding classification of works.
Any work that is unclassified will be assumed to need a meter by default. Many unclassified works however will not need a meter, they will only need to be correctly classified. 
Works can be correctly classified in the Water NSW customer Portal. The included links will help guide you through the portal. 



 

The Gwydir Unregulated Water Sharing Plan were released and became active on Thursday 2nd April. We have significant issue, as many of the changes were not consulted in any way. Issues raised on several water sources were ignored, the wetlands map does not provide necessary detail for landholders, there still hasn't been consultation with impacted landholders, activities near prescribed wetlands is being impacted and provisions have been added to allow changes for policy that is non government.  
Details are available on the government website link included. A summary of changes is available on the attached sheet

The MDBA will be meeting with community outside Brookers Trading on Balo St for 2-4pm on Monday 30th March

The GVIA will be hosting the MDBA at our office at 10:00 am on Tuesday 31st March - Please join us. 

The key messages are detailed in the attached file. In summary
-  No Rule Changes, compulsory acquisition is not appropriate
-  No more water from Agriculture, 72% of water is already for the environment
-  Community supported constraints must be completed, the NSW government must be held accountable
-  Complementary measures such as carp control must be implemented
-  Infrastructure must be updated at Menindee and to provide critical needs
-  Socio-economic impacts must be recognised appropriately
-  The Gwydir SDL do not need adjusting 


The MDBA will be meeting with the Gwydir CGA on Monday the 16th March. Some of the key people from the MDBA will be present to talk through current issues and the Discussion Paper.
This will be at the Social Co-House in Moree on Monday 16 March at 3.00 pm to 4.00pm.
For more details and information please reach out to Georgina on secretary@gwydircotton.com.au

Lower Gwydir Groundwater source update

Gwydir CAG afternoon session: Tuesday 17 March 2026 – 1:00pm to 4:30pm At: Social Co House
Cate Barrett and Thomas Walters, Hydrogeologists from the Groundwater Management and Science, Water Science will be providing an update on the Lower Gwydir Ground water Source. 
We encourage ground water entitlement holders to attend to be provided an update. This is important to help inform our understanding of the risks for the water source. 

Please find included our proposals regarding the Initial SDL Assessment Lower Gwydir Alluvium (GS24). Expectation that the trade restrictions fully implemented across the water resource in 2023 will continue to show improvements in the recharge capacity or the resource once they have been in place for a minimum of 10 years. The GVIA Request the following;

1. No change to SDL until management arrangements (trade restrictions) have had time to demonstrate that they are suitable.

2. Support maintaining the existing trade restrictions until 2035 (15 years) to enable their impact to be fully appreciated.

3. Support maintaining the existing carryover.

4. Users are actively engaged in consultation on the Water source between the MDBA and NSW DCCEEW before any changes to management are made.

The Menindee Lakes Review aims to define the issues with the current management the Menindee Lakes and explore options for improved managing the Lakes for the health and resilience of Basin communities, industries and the environment. The GVIA want this to be for upstream and downstream communities, not just downstream as is currently occurring. The MDBA see it as an opportunity to strengthen what is currently working and identify where change might be needed. The review, by the MDBA on behalf of the joint River Murray governments, complements ongoing work by New South Wales to improve water resource management and environmental outcomes in the region as outlined in the Menindee Review Consultation Paper.
Of most concern to GVIA members is that the review is focused downstream of the lakes in the lower Darling and Murray. Yet when mismanagement leads to an outcome that politicians don't like, everyone expects the problem to be solved by restricting water sources upstream. The GVIA will be ensuring that we do everything we can to raising our concerns. We will be pushing strongly for the Pamamaroo inlet regulator to be fixed, as it is one of the areas where failure to address problems in a timely and efficient manner is having negative impacts on northern basin entitlement holders and their communities. 

Landholders can apply for a $1000 or $2000 reimbursement if they extract water from groundwater, or regulated or unregulated river sources in the Murray–Darling Basin and hold an annual entitlement of 100 ML or greater.
It’s also on offer farmers and landholders who have used 100 ML of water or more in any one year since 2023.
The cashback ensures water users who are required to install telemetry devices but choose to engage their own duly qualified person (DQP) instead of participating in the program’s free device rollout, which is currently underway across inland regions of the state.

The recently released MDBA discussion paper identified in the initial assessment of Sustainable Diversion Limits (SDL) that there are risks for us.
The Gwydir surface SDL may not support Basin Plan environmental outcomes. This is primarily related to floodplain inundation and waterbird breeding in the ramsar sites. It is tightly linked to the Northern Toolkit Gwydir constraints project. The MDBA is supporting the completion of the reconnecting water course country program. The GVIA will support community supported constraints' management as an overriding principle. 
The Lower Gwydir Alluvial SDL was also identified as being at risk. This is primarily as the recharge has not occurred as would be ideal. Importantly we must accept that as it is a large aquifer with high buffering it takes a long time for changes in recharge to affect overall levels, i.e. the aquifer has low sensitivity to use or changes in recharge. Trade restrictions implemented from 2020 to 2023 are showing positive outcomes. We will be supporting the existing trade restrictions put in place by DCCEEW for an extended time, 15 years, to enable time for changes to be observed. As such the GVIA will be working towards no changes to SDL until 2035. 

Basin Plan Discussion Paper

In early February the MDBA released the Basin Plan Discussion Paper. This is the four document which inform the review and the development of the next Basin Plan. The document suggests that we need more of a management plan now. There are however still some concerns. The assumptions informing the discussion paper are that SDLAM project will be completed and the whole 450GL for the southern connected system will be recovered. Of most concern is that 100GL of this will be from the north. The document also talks about creating connectivity in the north and the use of rule changes. Neither of which are acceptable to our members. We have consistently stated that 

  • We support the MDBA position that 320GL water recovery in the Northern Basin is sufficient to satisfy the Environmentally Sustainable Level of Take (ESLT) requirements of the Water Act.
  • We do Not believe water for the 450GL should be recovered from the northern Basin.
  • If the Government wishes to recover water towards the 450GL or connectivity, they must purchase it on the open market.


If you would like some high level information the MDBA hosted a webinar

The department released the latest Gwydir regulated Water allocation update on the 6th February. There has been no allocation to general security (GS) licences.
The GS account balance is about 479 gigalitres (GL), or an average 94% of entitlement. Of this 144GL is HEW. 
The environmental water allowance (EWA) balance is about 73 GL, or an average of 162% of entitlement.
During January, total essential supply demand was about 3.8 GL, and GS usage was approximately 109.2 GL. Average GS account balance is 94%
Around 7.8 GL of EWA delivered during this period, resulting in an average account balance of 16@% as of 31st January.
All the forecast quantiles sit well below the historical flows, indicating that inflows from January to March 2026 will likely be lower than historical levels.

The GVIA currently has three ground water parcels available for temporary trade. Please email Lou at gvia@gvia.org.au if you have any questions.
