Brief description

## **Abstract**

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.



The data is used for streamflow annual time series analysis for the Sydney subregion. It summarises the mean monthly flow characteristics including monthly streamflow ratio (monthly mean divided by annual mean) distribution, for the Sydney Basin bioregion based on the streamflow data from the 68 gauging stations. Also calculated are mean annual flow volumes summarising mean annual flows for a selection of gauging sites in each of the major river basins in the Sydney Basin bioregion.

## **Dataset History**

This dataset was generated using daily streamflow data obtained from the Sydney Catchment Authority and BoM. A subset of gauges were used to represent the major river basins in the Sydney Basin bioregion. Selection was based on gauges with the most number of days of data and the start and end dates vary across the sites. Data are collected at sites with very small contributing areas (a few square kilometres) through to sites with large contributing areas (thousands of square kilometres), hence there is considerable variability in the mean annual flows. Many of the gauges, particularly in the Hawkesbury and Shoalhaven river basins, are downstream of dams and their flow regimes will differ from pre-dam flows.
