The Macquarie River is located within the Murray-Darling Drainage Division in central New South Wales. Although the complete Macquarie River catchment includes regulated and unregulated areas, only the regulated area was assessed for the water balance.
The Macquarie River is a tributary of the Barwon River, which in turn is a tributary of the Darling River. It has several tributaries, including the Bell, Cambells and Fish Rivers and there is complex system of anabranches and creeks in the lower catchment that connect the Macquarie River with the Bogan and Darling Rivers. The Macquarie Marshes are located in the north-east corner of the catchment and the Macquarie River does emerge from the wetlands before being joined by the Castlereagh River and then flowing into the Barwon River near Brewarrina. The Bogan River rises in the Harvey Ranges between Parkes and Peak Hill and flows northwest through a broad, flat landscape through Nyngan to join the Darling River near Bourke.
Irrigation within the Macquarie River – Regulated WMA includes private irrigation as well as several irrigation schemes (Narromine - Trangie, Buddah Lakes, Tenandra, Trangie – Nevertire, Nevertire and Marthaguy). There are two primary water storages within the study area, Burrendong and Windamere Dams. Major towns in the area include Dubbo, Wellington and Mudgee.
The Department of Natural Resources (DNR) is the licensing authority and manages both surface and groundwater diversions for urban, commercial/industrial, irrigation and environmental purposes. The Central West CMA is responsible for managing the native vegetation, soil and other natural resources in the catchment in conjunction with the community, local government, industry and State Government. State Water [http://www.statewater.com.au] manages the major water supply storages in New South Wales and supplies bulk water to the irrigation authorities, town water supply authorities, mines, electricity generators and other industry by releasing water from its dams into rivers to be accessed by downstream water users. State Water also delivers water for private irrigators and stock and domestic users and is responsible for delivering environmental flows, in accordance with rules as set out in NSW Water Sharing Plans, on regulated rivers in the state. Local councils treat the bulk water and deliver it to urban users in the major towns within the catchment as well as managing the wastewater collection and treatment network (e.g. Dubbo City Council).
