Macquarie-Castlereagh Long-Term Water Plan Part A: Macquarie-Castlereagh catchment

The Macquarie–Castlereagh Long-Term Water Plan (LTWP) is an important step to describing the flow regimes that are required to maintain or improve environmental outcomes in the Macquarie–Castlereagh catchment. The plan identifies water management strategies for maintaining and improving the long-term health of the Macquarie–Castlereagh’s riverine and floodplain environmental assets and the ecological functions they perform. This includes detailed descriptions of ecologically important river flows and risks to achieving ecological objectives.

Importantly, the LTWP does not prescribe how environmental water should be managed in the future, rather it will help water managers and advisory groups, such as the Macquarie–Castlereagh Environmental Flows Reference Group, make decisions about where, when and how water can be used to achieve agreed long-term ecological objectives.

The LTWP looks at all sources of water and how these can be managed to help support environmental outcomes in the catchment.
