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.

    Some members with FPH licences will not be using all storages in their works approvals to take water when the opportunity occurs. If this is the case you will need to make these storages inactive, now referred to as "classified as not taking licensed water". These storages  can be made active into the future if your situation changes. Please read the guide, and or watch the video. 
    Please follow the link included. Scroll down to the section Amend the works as not taking FPH water

    National environment listing in MDB, just words not action

    15 January 2026, Canberra, ACT: Today’s announcement to list parts of the Murray Darling Basin floodplains as “critically endangered” under the updated Environment Protection and Biodiversity Conservation Act 1999 (Cth) adds another layer of complexity to already heavy regulation in the Basin – and will achieve little without real investment in addressing delivery constraints and major threats like carp.

    The GVIA are currently looking for a Project and Policy Support Officer. 
    The project officer role would entail working on behalf of and in partnership with the GVIA Members to deliver requirements as detailed in projects.
    The policy support role will entail supporting the EO in the review and analysis of regulatory policy and provide support to Members in the interpretation and application of policy.
    The role would also support the EO in communication of water related issues to the wider community. 
    More detail are available in the attached position description.
    To apply or arrange to discuss the position please email the EO on gvia@gvia.org.au

    The Gwydir AWD released on the 12th Jan 2026 indicated that there was an estimated 6 GL of inflows into Copeton Dam and 2 GL from the downstream tributaries during Dec 2025, and therefore no allocation increment to General Security (GS) or ECA licences. 
    The average GS account balance is 115%, while the ECA account balance is 180%.
    During December, total essential supply demand was about 4.9 GL, and GS usage was approximately 29.9 GL. Around 6.9 GL of EWA delivered during this period.

    In partnership with the NSW Government, TAFE NSW has launched a free, 3-hour online course designed to fast-track qualified tradespeople into becoming duly qualified persons (DQPs). DQP's can: 

    • install and validate non-urban water meters 
    • ensure installations meet compliance and safety standards 
    • offer ongoing servicing and maintenance
    • support sustainable, responsible water management. 


    The following trades can apply: irrigation technician, plumber, instrumentation specialist, hydrographer, engineer, fitter-welder, closed conduit meter manufacturer, electrician, local intelligence device manufacturer, or telecommunications technician.
