Catchment management

Catchment management Waller Creek rehabilitation.jpg

Rain that falls within Blacktown City flows into 2 major catchments, either Sydney Harbour via the Parramatta River or the Hawkesbury-Nepean River via South Creek. Within these 2 major catchments there are 22 subcatchments with 262 km of defined drainage lines.

In 2015 we conducted a rapid riparian assessment at 600 metre intervals on every creek.

We are developing subcatchment management plans for all 22 subcatchments(PDF, 2MB) . We are doing this by:

  • identifying the current land use and updating the spatial layers

  • analysing water quality, geomorphology and rapid riparian assessment data

  • identifying priority areas and project opportunities to improve liveability, waterway condition, ecological improvements.

The main outcome of the subcatchment planning process is to define the current condition and suggest future actions to improve or protect waterway health.
