River Level Daily Mean 9am - 9am M Sydney Catchment Authority 20150727

## **Abstract** 

This dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied.  The metadata was not provided by the data supplier and has been compiled by the programme based on known details at the time of acquisition.



This was a special data request performed by Sydney Catchment Authority (SCA) for river levels of selected gauges in the Sydney/Hunter area.  

These are daily mean with 9.00am to9.00am figures in Metres.  For guages supplied to SCA for them to query please see spreadsheet in data folder. 

Quality codes are also documented in the data folder.  

Note that total daily stream flow (water course discharge) for the same selected gauges was aquired earlier in the programme and can be 

found in the following dataset:

 'Total Daily Stream flow Sydney Catchment Authority 20141211'

GUID = 019128a1-d747-4ac2-842d-c0b30a4f8627

## **Purpose** 

Records river level height at selected Sydney Catchment Authority guages
