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.

Pollution Incident Response Management Plan

To report a pollution complaint or incident, call 1300 138 265.

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 2020/2021 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, there was above average rainfall in March 2021 and June 2021, November 2020, December 2020 and April 2021 were very dry with close to average rainfall for the remaining months over the entire Murray Irrigation area of operations. Evapotranspiration was close to average over the entire area during 2020/21.

General Security Allocation for 2020/21 was 50%, general security allocation in 2019/20 was 3%.

In 2020/21, water delivery on-farm was 573,911ML, well above the previous year’s on-farm delivery (87,561ML in 2019/20). Delivery of environmental water (27,519ML) was higher than the previous year (14,470ML in 2019/20). The volume of water delivered for environmental purposes has increased over the last three years (8,602ML in 2018/19). Discharges from the stormwater escapes (728ML) were low reflecting the average rainfall for the year.

Delivery of water for operational purposes under agreement with WaterNSW in 2020/21 (258,167ML) was higher than the previous year (180,841ML in 2019/20). The discharge of water from supply channel escapes without credit are no longer recorded by Murray Irrigation as the implementation of the operating efficiencies following the completion of the supply system semi-automation are realised.

Murray Irrigation’s delivery efficiency was 93%.

In 2020/21 the highest water use by crop type was rice (33% of the water delivered), followed by winter crops (24% of the water delivered) and annual pasture (17% of the water delivered). Compared to 2019/20, where winter crops were the highest water use by crop type (35% of the water delivered) followed by annual pasture (26% of the water delivered) and horticulture (15% of the water delivered). This is a reflection of the seasonal conditions experienced, especially in relation to the considerably higher allocation for general security water, with a return to the growing of rice.

The area impacted by watertable within two metres of the surface (366ha) is similar than the previous year (349ha in 2019/20). In contrast, the area impacted by watertable within 4m of the surface decreased (10,367ha) compared to the previous year (14,068ha in 2019/20). The rationalized piezometer network was used for the first time in August 2019.

The areas impacted by water table higher than 4m in August 2020 were the same as the previous year in August 2019, the areas concerned are located in the centre of Wakool area and in the area north of Barooga. These are the two areas that have historically been impacted by high watertable.

There was no request to measure the salinity of the groundwater during 2020/21.

Murray Irrigation is a net importer of salt (24,921 tonnes imported). The extracted amount of salt (35,491 tonnes) was higher than previous years (13,122 tonnes in 2019/20) due the higher volumes of water extracted. The discharged amount of salt from the supply channel under agreement (10,474 tonnes) was higher than previous years (6,652 tonnes in 2019/20) due the increase in volume of water discharged from the supply channel under agreement in 2020/21.

The Wakool-Tullakool Sub-surface drainage scheme (WTSSDS) was not required operational during 2020/21.
