The Namoi River is located within the Murray-Darling Drainage Division in northern New South Wales. Although the complete Namoi River catchment includes regulated and unregulated areas, only the regulated area was assessed for the water balance.
The Namoi River – Regulated WMA included the regulated Namoi, Peel and Upper Manilla Rivers downstream of Split Rock Dam. The Namoi River is a tributary of the Barwon River, which in turn is a tributary of the Darling River. It has several tributaries, including the Macdonald, Peel, Manilla and Mooki Rivers and Coxs Creek. Irrigation within the Namoi River – Regulated WMA is predominantly private irrigation (i.e. not delivered by an irrigation authority). Keepit, Split Rock and Chaffey Dams are the primary water storages in the WMA and the major towns include Tamworth, Gunnedah and Narrabri. The main purpose of Chaffey Dam is to provide town water supply to the Tamworth region and to guarantee its long term security of water supply.
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 Namoi CMA is responsible for managing the native vegetation, soil and other natural resources in the catchment in conjunction with the local 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. Local councils have the responsibility to treat the bulk water and deliver it to urban users in the major towns within the catchment and also manage the wastewater collection and treatment network (e.g. Tamworth Regional Council.
