Adelaide

The volume reported in the water accounting statement (106,162 ML) represents streamflow out of the Adelaide region into the ocean. The table below presents streamflow out of the Adelaide region during 2009–10 by stream gauge.

* Flow records are only available for part of 2009–10.

Data sources

Streamflow data from Water Data Services website

Data provider

South Australian Department for Water.

Method

This line item represents streamflow from the Adelaide region into the ocean. The total flow volume was obtained by summing 2009–10 streamflow from gauging stations on most major rivers in the Adelaide region including the Gawler, Torrens, Little Para and Onkaparinga rivers. Each gauging station monitors stream height, which is converted to a flow volume using a rating table.

Uncertainty

Ungraded.

Assumptions, approximations and caveats/limitations

• Streamflow data was not available for all major rivers. The Myponga River is the most significant omission; it is not measured downstream of the Myponga Reservoir. The rivers of the Fleurieu Peninsula have also been omitted, including Yankalilla, Inman and Hindmarsh rivers.
• Streamflow records for the Little Para and Field rivers were only available for part of the reporting period. Data was available from March to June 2010 for the Little Para River, and May to June 2010 for the Field River.
• The rating table used to obtain the flow volume from the measured water-level is assumed to hold for the full range of the measured water-level.
