Building a secure future for members, the environment and the Gwydir Valley community through irrigated agriculture

Gwydir Valley Irrigators Association

The Gwydir Valley Irrigators Association (GVIA) represents in excess of 400 water entitlement holders in the Gwydir Valley.

Our water entitlement holders are some of the most progressive in the world, actively engaged in, and innovating irrigated agriculture. From broadacre crops such as cotton to tree crops such as pecans, oranges and olives, our industry is diverse and productive. We are all acutely aware that reliability of water in the valley is low, and thus strive to Make Every Drop Count for the producer, the community and the environment. Read more about us

Gwydir River - Gravesend Monitoring Gauge

WaterNSW monitor 51 river gauge locations in the Gwydir River and streams(418) using telemetry with data accessible in real time. These sites collect a range of information from flow rate, discharge volume and river heights and assist WaterNSW in their role of water delivery operators whilst providing an indication of water availability.

Water Management

All water in the Gwydir is managed by water sharing plans established progressively since 2004. Currently 19% of long term Gwydir river flows and 85% of sustainable yield of the Lower Gwydir aquifer are available for irrigation. This has been reduced over time following reforms and water recovery for environment.

Groundwater Monitoring Network

The are a number of groundwater sources including the Lower Gwydir aquifer used for irrigation and the Great Artesian Basin, including recharge zones. WaterNSW monitor levels via 26 monitoring sites with data accessible in real time.

Groundwater provides reliable irrigation water, quality drinking water for towns and properties and is one of the region’s major tourism attractions.

Latest News & Events

The NSW DCCEEW announced s324 water restrictions are in place as of today the 17th April 2026.
These are designed to be extreme event policies, however the government have decided to apply the s324 as the active volume in the upper Menindee lakes has fallen below 250GL.
We have argued against this and were able to get the relaxation triggers for FPH in line with those in the Gwydir WSP, a significant win. The restrictions in the Gwydir are as follows:
Gwydir Regulated River Water Source
• floodplain harvesting (regulated river) access licences {The relaxation triggers for FPH licences (as per those already in the WSP, linked to 195GL total storage)}
• supplementary water access licences
Gingham Watercourse Water Source
• floodplain harvesting (unregulated river) access licences
• unregulated river access licences
Mallowa Creek Management Zone in the Mehi River Water Source
• unregulated river access licences
Full details of the restrictions are available on the department website link included

FPH storage classification

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

Amend - To ensure your approval is correct, it's your responsibility to confirm that your approval matches the works listed.
Select Works that are classified as not taking licensed water
To classify your work as not taking licensed water (water supply work or floodplain harvesting), please login or register in the Customer Portal and complete the ‘Amend the status of your work’ form.
