The overarching purpose of this environmental watering action is to maintain the ecological health and resilience of the Macquarie Marshes. This will include contributing to meeting the basic annual water requirements of native marsh plant communities such as water couch, reeds, typha, spike rush and club rush, and provide freshes in support of native fish reproduction.
Commonwealth environmental water will be delivered to the Marshes as managed releases from Burrendong Dam in the upper Macquarie catchment between mid July and November 2013. Up to 10,000 ML of Commonwealth environmental water in conjunction with up to 50,000 ML of NSW environmental water will contribute to a two stage delivery, namely:
- Up to 51,000 ML, comprising 7,500 ML of Commonwealth and 43,500 ML of NSW environmental water, to be delivered over a three month period commencing in mid July 2013 with the intention of inundating permanent and semi permanent wetlands in the North and South Macquarie Marshes Nature reserve; and
- Up to 9,000 ML, comprising 2,500 ML of Commonwealth and 6,500 ML of NSW environmental water, to be delivered to the Gum Cowal-Terrigal system in the East Macquarie Marshes area over a two month period starting in September to provide flows to semi permanent wetlands and riparian vegetation. This delivery is intended to coincide with warmer water temperatures to also provide hydrologic connectivity and conditions for native fish to access breeding habitat at key reproduction times.
This watering action will be managed in cooperation with the NSW Office of Environment and Heritage, NSW State Water with local community advice from the Macquarie and Cudgegong Environmental Flow Reference Group .
