Environmental flows update
Environmental flows are currently being released targeting the Gingham. These will last for approximately 6 weeks, or until the Gingham waterhole has filled.
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

The irrigated olive industry was initiated in the Gwydir Valley over 25 years ago. Olives are a vertically integrated industry with the nationally recognised Gwydir Grove Olives the largest local producer and processor. In recent years the number of olive trees has declined as some producers have switched from olives into pecans.
Oranges are a new irrigation industry in the Gwydir Valley, with the majority of the trees planted since 2005. It is currently expanding with an expected area of 350Ha to be under production by 2020. The citrus industry in the Gwydir Valley is part of the locally owned and vertically integrated Grove Juice business.
The pecan industry is an important irrigation industry for the Gwydir Valley. Trawalla, owned and operated by Stahmann Farms is the largest in the region producing approximately 90% of Australia’s pecans. Australia is the fourth largest global producer of pecans. Stahmann Farms operate the country's only commercial pecan shelling, value-adding and packing plant.
The Gwydir Valley is a diverse broadacre cropping region producing a range of both summer and winter crops. The primary winter crops include; chickpeas, wheat, barley, and more recently canola. While summer plantings include sorghum, faba beans, mung beans, maize and sunflowers. The majority of the broadacre cropping area is dryland.
Cotton is the most significant irrigated crop in the Gwydir Valley with an average of 70,000Ha. It is also an important dryland crop with an average of 79,000Ha annually. The area planted can fluctuate from year to year, being dependant on either available irrigation water and seasonal rainfall.
Lucerne and Hay are niche crops in the Gwydir Valley covering an estimated 4,500Ha. Lucerne is produced primarily on smaller blocks and is irrigated by bore water entitlements. Hay production includes Lucerne, cereals and pastures.
The turf industry has been a part of the irrigation industry of the Gwydir Valley for almost 20 years, but there are only two producers in the valley. It covers a very small area of only 20Ha and is irrigated by bore water entitlements. The primary species produced is Buffalo.
The Gwydir Wetlands are a system of terminal delta wetlands, located downstream of the Gwydir River approximately 45kms west of Moree in north west NSW. They are recognised for their unique vegetation and bird breeding potential. The wetlands are estimated to consist of approximately 6,829Ha of semi-permanent wetland and 77,949Ha of floodplain wetland.
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.
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.
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.
Copeton Dam is located on the Gwydir River upstream of Bingara on the north-west slopes of NSW. It is one of the largest inland dams in NSW with a capacity of 1,364,000 megalitres of water. It was initiated in 1966 to provide town water supplies and to boost irrigated agricultural production in the Gwydir Valley.
Environmental flows are currently being released targeting the Gingham. These will last for approximately 6 weeks, or until the Gingham waterhole has filled.
The Easement Inundation Amendments went through NSW parliament this week, coming into effect on Monday the 18th May 2026.
Water NSW has provided the following information.
"We recognise the potential for impacts to some landholders in the Gwydir, and are committed to operating
in good faith and providing adequate advance notification of any future environment water releases that may
affect landholders.
The environmental water holders will also continue to liaise with potentially impacted landholders, and
provide information on the extent, timing, duration and purpose of their watering events.
To receive notifications from WaterNSW, please sign up to receive ‘environmental water release’ alerts through our Early
Warning Network (EWN) platform. "
Please find included Media from the shadow water minister Steph Cooke MP and our local member, shadow agricultural minister Brendan Moylan MP.
The media is related to the Water Management Amendment (Easements for Inundation) Bill 2026.
The Opposition moved an amendment to provide for a statutory Deed of Release pathway as an alternative to enduring easements. This would have provided landholders with a more flexible, negotiated and reviewable mechanism, while still allowing environmental watering outcomes to be delivered responsibly. This amendment was not supported by Labor or the Greens. The Bill was rushed through the Legislative Council with the Greens' support on 7 May 2026.
The Bill is now awaiting consideration by the Legislative Assembly, anticipated it may be brought on for debate in the coming days.
