INTRODUCTION
The Narellan Creek catchment covers an area of 35 km2 within the Camden Council Local
Government Area. It incorporates Narellan Creek as well as a number of tributaries
including:
Kenny Creek
Annan Creek
Thornleigh Gully
Howe Rivulet
Cross Creek
Condron Creek
Herbert Rivulet
Oxley Rivulet
As shown in Figure 1 (enclosed in Volume 2), the study area extends across parts of the
suburbs of Narellan, Narellan Vale, Harrington Park, Currans Hill, Kirkham, Elderslie, and
Mount Annan.

they have focussed on defining the flood risk from
