The Hunter River is located within the South-East Coast Drainage Division in central New South Wales. Although the complete Hunter River catchment includes regulated and unregulated areas, only the regulated area was assessed for the water balance.
The Hunter River is a major coastal river that discharges to the ocean at Newcastle. It has several tributaries, including the Goulburn River, Williams River and Pages Creek. Lake Glenbawn, Glennies Creek Dam (Lake St Clair) and Lostock Dam are the major water storages within the regulated area and the major towns include Maitland, Muswellbrook and Singleton. The city of Newcastle is downstream of the regulated section of the Hunter River.
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 Hunter – Central Rivers 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 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.
Hunter Water operates in Newcastle and its surrounds treating and distributing drinking water as well as collecting and treating wastewater. In other areas of the catchment, the local council treats the bulk water and delivers it to urban users in the major towns within the catchment and also manage the wastewater collection and treatment network (e.g. Muswellbrook Shire Council. Both surface and groundwater resources are used for urban water supply in the Hunter River – Regulated WMA. Macquarie Generation own and operate two power stations in the catchment (Liddell and Bayswater) and is the major industrial consumer of water (for coal mining) in the catchment.
