Water catchments in the Murray–Darling Basin
Map of the Murray–Darling Basin region within Australia. It shows the catchments that we provide data for, within the Basin area.
Each catchment on the map can be selected to display related information. This information can also be accessed using the Select a Basin area or catchment control above the map.
The map shows storages, river gauges and groundwater bores across the Basin. Data for each includes:
- storage volume as a percentage of capacity (current and same time last year) and current megalitre amount.
- river gauge flow, height and quality.
- groundwater bore depth to water (current and beginning of season) and quality.

Water use
The catchment supports a diverse range of industry including agriculture, agribusiness, tourism, mining and viticulture. Extensive livestock grazing accounts for 70–80% of the land area in the catchment. The largest agricultural use of water in the valley is for cotton, downstream of Dubbo. Other significant irrigated crops in the region include lucerne, cereals, oilseed, wheat, vegetables and fruit. Irrigated agriculture accounts for less than 5% of land use in the catchment but makes up about 25% of production. The Macquarie–Castlereagh catchment is also home to internationally significant wetlands, the Macquarie Marshes.
