Compliance and monitoring
Annual compliance reporting
We produce an annual compliance report in accordance with our operating and environmental licences.
Compliance reports contain detailed technical data on a range of required environmental and operational parameters.
The climatic conditions in the area influence every aspect of these reports. The climate determines the volume of water available for irrigation, the volume of water used for irrigation, the volume of water discharged from the area and the rate of evaporation.

The following summarises the approach taken by Murray Irrigation to manage pollution incidents that involve our assets, the environment, customers and staff.
Summary of the 2018/2019 Annual Compliance Report
The climatic conditions in the area influence every aspect of this report. The climate determines the volume of water available for irrigation, the volume of water used for irrigation, the volume of water discharged from the area and the rate of evaporation.
With respect to the climate, it was an extremely dry year with above average evapotranspiration experienced across the entire Murray Irrigation Area of Operations. The entire area experienced an extremely dry January to April 2019.
General Security Allocation for 2018/19 was 0% with carryover of water from the previous year, general security allocation in 2017/18 was 51%.
In 2018/19, water delivery on-farm was 287,541ML, well below the previous year’s on-farm (786,631ML in 2017/18). Delivery of environmental water (8,602ML) was slightly higher than the previous year (5,978ML in 2017/18). Discharges from the stormwater escapes (126ML) were extremely low reflecting the exceptionally dry year.
In 2018/19 the highest water use by crop type was winter crops (33% of the water delivered), followed by annual pasture (24% of the water delivered) and summer crop (20% of the water delivered). Compared to 2017/18, where rice was the highest water use by crop type (40% of the water delivered) followed by annual pasture (21% of the water delivered) and winter cereals (17% of the water delivered). This is a reflection of the seasonal conditions experienced, especially in relation to the zero allocation for general security water in 2018/19.
