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 sub-catchments 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 sub-catchment management plans for all 22 sub-catchments. 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 sub-catchment planning process is to define the current condition and suggest future actions to improve or protect waterway health.
