MID Nutrients

NUTRIENT REDUCTION IN THE MID

Nutrients from the Macalister Irrigation District (MID) impact on the water quality in receiving streams and the Gippsland Lakes.

The sources of nutrients from the MID include fertilisers, manure and soil erosion. Nutrients contribute to algal blooms in the Gippsland Lakes.

Southern Rural Water, together with the West Gippsland Catchment Management Authority, Department of Economic Development, Jobs, Transport & Resources, and the Environment Protection Authority, undertakes nutrient reduction strategies, monitoring and reporting to meet the targets of the State Environment Protection Policy (Waters of Victoria) and the Macalister Land and Water Management Plan.

 


SRW Monitors Nutrients

SRW Monitors Nutrients

Southern Rural Water monitors the load of Total Phosphorus (TP) leaving the Macalister Irrigation District (MID).

We do this by monitoring Total Phosphorous at 8 carefully selected auto-sampler sites. These sites measure the TP load entering and exiting the MID, allowing SRW to calculate the TP load from the irrigation district.

The TP load discharged from the district is reported quarterly to the Environment Protection Authority. Modellers and researchers also use the data to advise on management actions to minimise nutrient loads.

Southern Rural Water actively supports nutrient reduction in the MID. See this video highlighting some of the significant environmental improvements that have been achieved in the district.

SRW actively participate in regional forums with other stakeholders to coordinate and improve our efforts, and provide data for research on nutrients and blue green algal blooms.

SRW, along with its partners, were recently awarded as finalists in the Premiers Sustainability Awards and the Banksia Sustainability Awards for their efforts in improving the health of the Gippsland Lakes through nutrient reduction and monitoring.

Our other activities include:

  • cooperating with landholders to convert drains into irrigation reuse systems
  • reporting illegal discharges to irrigation drains to the EPA
  • providing input to whole farm plans
  • reducing outfall of waters from irrigation channels into drains
  • revegetating irrigation drains
  • undertaking educational activities to promote nutrient reduction in the MID.

The MID 2030 Strategy outlines our approach, including drain modification and artificial wetlands, which together with improved irrigation delivery systems will produce positive outcomes for nutrient control.

The modernisation of the irrigation delivery system will allow farmers to irrigate more efficiently and reduce the volume of water leaving farms into the drainage system.

We actively participate in regional forums with other stakeholders to coordinate and improve our efforts, and we contribute to nutrient and blue green algae research.

Our other activities include:

  • cooperating with landholders to convert drains into irrigation reuse systems
  • reporting illegal discharges to irrigation drains to the EPA
  • providing input to whole farm plans
  • reducing outfall of waters from irrigation channels into drains
  • revegetating irrigation drains
  • contributing to Waterwatch
  • reporting nutrient updates
  • undertaking educational activities to promote nutrient reduction in the MID
