Changing Irrigation Systems and Management in the Harvey Irrigation Area

Milestone Report - End of Stage 1 - February 2004

The project is examining issues of water use efficiency (WUE) in the South West Irrigation Area (hereafter called the Harvey Irrigation Area). A significant WUE issue is whether water savings, improved pasture yields and farm productivity can be achieved through sprinkler (centre pivot) irrigation of dairy pasture in comparison with traditional surface bay irrigation (often called flood irrigation). This project is a case study conducted on (more)...

Final Report - February 2006

Irrigated agriculture commenced in Harvey with the establishment of a weir in 1916. Since that time, pastures have been watered through surface irrigation of paddocks which over time have been leveled and divided into irrigation bays.
