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.

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 NSW Real Time Data


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.
