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.

Our vision is for the local irrigation industry, the environment and the Gwydir Valley community to have a secure, vibrant future, with the GVIA recognised as an industry leader.

The Gwydir Valley, centred around the town of Moree in north west NSW is an extremely productive agricultural region. Agriculture employs 20-30% of the population and contributes an estimate 7.8% of NSW’s total agricultural production. Irrigated agriculture is particularly important, contributing significantly to the social and economic wellbeing of the region.

Olives

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.

Cotton

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

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 Gwydir Wetlands

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.

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.

Copeton Dam

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.

Today the MDBA have released the Constraints Relaxation Implementation Roadmap. Constraints relaxation were identified as a necessary component to enhance environmental outcomes from water recovery in the original Basin Plan. They were the driving force behind schedule 5 Enhanced environmental outcomes to increase the volume of water resources available for environmental use by 450 GL per year. There will be challenges for producers in our region. The roadmap states:
"New South Wales is also at an advanced stage in the planning of constraints relaxation implementation in the Gwydir. Engagement with stakeholders and landholders has identified key issues to delivery that mean full implementation will likely extend beyond December 2026. The Australian and NSW governments are working together to rescope the Reconnecting Watercourse Country Program to ensure tangible outcomes are delivered to relax system constraints in the Gwydir by December 2026. In April 2025, NSW will provide an options assessment report to the Commonwealth identifying the preferred delivery option for a rescoped program."
