Basins & catchments
Our department plays an important role in researching and reporting on rivers, groundwater and catchment health.
We are developing detailed catchment description reports, initially for the major inland regulated river valleys and later covering the whole state. The reports include information such as climate, hydrology, environmental aspects, land use, water resources, regulating structures and water resource management.
Murray Darling Basin
The Murray-Darling Basin is the catchment for the Murray and Darling Rivers and all their tributaries, covering most of inland NSW and extending from Queensland to South Australia.
Great Artesian Basin
The Great Artesian Basin lies beneath 22 per cent of Australia - including 12 per cent of New South Wales. One of the largest groundwater basins in the world it is often the only reliable source of stock water in the far west of the state.
The upper catchments of the Snowy River Basin are in south-east NSW. Of the lower catchments, 50 per cent are in north-eastern Victoria. The NSW portion of the catchment area is 9,070 square kilometres.
