Systems Repair funding increases irrigation capacity and helps improve water quality entering local waterways.
Bakers Creek sugarcane grower, Shane Cowley, has been able to increase the on-farm water supply available for cane farm irrigation by installing a sediment detention basin and second flush chamber directly upstream from his wetland, which flows into Bakers Creek.
With assistance from the Australian Government’s Systems Repair program, Shane was able to build a 1 ML first flush detention basin that catches most of the sediment in the runoff water entering his farm.
A second flush chamber was also created, consisting of a long deep marsh (sedges) zone for filtering nutrients and fine sediment from the water. The second flush chamber features a 3 ML waterhole at its end to supply irrigation water.
The water flows over a rock weir at the end of the waterhole into Shane’s wetland, ensuring cleaner re-oxygenated water entering the wetland.
The project has been successful, and is set to deliver both environmental and production benefits.
“This extra water means that I can irrigate those nearby cane blocks several more times each year and significantly increase their production, as well as improving the water quality for my wetland and the Great Barrier Reef Lagoon,” Shane said.
A rock ramp fishway was incorporated at the exit of the wetland, enabling both scour protection and fish connectivity with downstream habitats. Shane is also a keen fisherman and hopes the fishway will help attract barramundi into the wetland.
Systems Repair project funding available to farmers is an additional source of funding, separate from the Reef Programme water quality grants (formerly Reef Rescue).
Reef Catchments worked together with Shane on this project to provide help with the system design and funding for up to 50% of the costs. The project was recently completed with the additional structures now filling from recent rainfall events. The wetland has also been revegetated with native plants to restore habitat and connectivity.
