This audit report covers the 16,000 square kilometre Sydney Drinking Water Catchment, including the Special Areas around storages and outer catchment areas.
The audit examined 16 indicators to give a snapshot of the catchment condition over 2 years, between 1 July 2003 and 30 June 2005.
Report findings included:
- parts of the catchment were in good condition, especially around the Special Areas
- the Wingecarribee, Kangaroo and Wollondilly River sub-catchments were subject to the most pressures, causing poor conditions for some indicators
- the presence of pathogens was a concern at some locations
- the incidence of algal blooms was a concern at some locations
- better data was needed to determine the catchment condition for surface and groundwater extraction, soil erosion, dryland salinity, fish communities, and condition of riparian and native vegetation
- catchment monitoring programs needed to be better integrated to improve the potential to establish links between cause and catchment condition
- integration of management and response programs needed to be continued to ensure efficiency.
The Audit Report made 25 recommendations in response to these findings.
