David Grace, a highly regarded farmer and horse training instructor, has been using the fish-friendly screen installed by the Fish Friendly Water Extraction Project on his Condamine River property, Coolibah. David observed countless small fish that had been sucked into the lagoon after irrigation pumping. After running the pumps through the fish screen, zero fish were drawn through the system, a significant win for fish conservation and sustainable water use.
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.
"A real positive outcome for native fish and farming."

Features of the Installed Fish Screen
• Handles up to 10-12 megalitres per day, meeting the irrigation needs of the property.
• Designed to withstand high-flow events, ensuring durability during dynamic river conditions.
• Self-cleans using a propeller-driven system, keeping 2mm openings free of algae and silt.
Why This Matters
- Protects native fish populations by keeping them in the river where they belong.
- Prevents debris from entering the pump, improving efficiency.
- Simplifies maintenance, even during high river levels or floods.
