About the project
The Macquarie Marshes is one of the largest remaining inland semi-permanent wetlands in the state’s central north-west. The area is an important nesting site for many native and waterbird species and provides a habitat for other animals.
The flow-dependent vegetation of the Macquarie River floodplain and Macquarie Marshes rely on a variety of flows to maintain them, including large ‘freshes’ to support the vegetation and wildlife.
The Macquarie Marshes Enhanced Watering project will improve environmental watering to the marshes during dry periods by reducing the volume of water lost from the river via an eroded stream. Other works will investigate improving the connection of the river to the floodplain.
Potential infrastructure solutions include bed restoration works at the inlet to the Oxley Break No 3 and works at the Mumblebone Breaks upstream of Marebone Weir. We’re reviewing options and assessing the best way to complete this work.
The project is funded by the Australian Government and is being delivered by Water Infrastructure NSW in partnership with Department of Planning and Environment – Environment, Energy and Science.
The works will generate significant environmental benefits including:
- higher flow rates to the Macquarie Marshes to support native vegetation and wildlife
- improved connection of the river and wetlands to the floodplain
- enhanced control of flows through key areas in the south marsh
- stabilisation of eroding streams.
The Oxley Break No.3 and the Mumblebone Breaks are located in Macquarie Marshes Nature Reserve, which is in central north-west NSW, around 80 km north of Warren and 30 km west of Quambone.
