Southern Queensland Landscapes, as part of the Fish Friendly Water Extraction Project, recently installed a cylindrical fish screen on the property
Nangram, part of the Wallumba Feedlot.
Nangram
is located on the Condamine River and is made up of nine irrigated centre pivots. As well as providing forage sorghum grazing to background cattle for the feedlot,
Nangram also grows all the silage to be used at Wallumba Feedlot.
Wallumba Feedlot operations embrace the principles of ecologically sustainable land management. They recognise that a healthy, diverse and resilient landscape is essential if beef production is to remain viable in Australia.
Though testing is in its early stages, the screen has already demonstrated its ability to protect native fish and prevent debris from entering the pump. Monitoring is being undertaken by Redleaf Environmental.

The Filter Installation
- One AWMA-manufactured fish screen was fitted to the current irrigation system.
- The screen is self-cleaning, driven via an internal propeller that rotates as water is pumped through the suction line.
- Internal and external brushes ensure that the screen remains clean, and any entrained debris is returned to the river.
Why This Matters for Farmers:
- Protecting Fish Populations → Ensures native species thrive while maintaining biodiversity.
- Reducing Infrastructure Maintenance → Fish screens help prevent debris blockages and extend the life of pumps.
- Regulatory and Financial Advantages → Demonstrating environmental responsibility could support water license security and financial incentives from institutions.
