Hydrologic Reference Stations


The Hydrologic Reference Stations identifies Australian streamflow trends and detects long-term variability and change in streamflow.

You can search the national network of 467 stations from a single website and view or download comprehensive streamflow information for a specific station. Using the online tool you can select a station, explore and display streamflow data as an annual, seasonal, monthly or daily time series. You can also explore trends in streamflow using the trend explorer for the Hydrologic Reference Stations.

The Hydrologic Reference Stations are well-maintained river gauges of long, high quality streamflow records managed by Australian and State water agencies. The stations can be used to estimate trends in long-term and seasonal water availability from climate variability and change.

Spread across contrasting hydro-climatic regions, the network includes unregulated streamflow stations in catchments with minimal effects of water resource development and land use change. The main objective of the Hydrologic Reference Stations is to allow for detection and attribution of long-term streamflow variability and change.

The Hydrologic Reference Stations is delivered by the Bureau of Meteorology, which has responsibility for compiling and delivering Australia's water information, as part of the Australian Government's $450 million Improving Water Information Program.
