The Mudflat Creek catchment is characterised by a distinct upper and lower section. The upper section of the catchment is located in the plateau area of Killcare Heights. This section of the catchment comprises of residential development around Wards Hill Road, The Scenic Road and Stewart Street together with a large proportion of natural bushland or rural type land.

From the plateau the catchment slopes very steeply down undeveloped, densely forested slopes to the area bounded by Fraser Road and Hardys Bay. This lower section is relatively flat and low lying. Runoff from the plateau area drains to Fraser Road via two natural gullies. Pipe and overland flow systems convey flows from these natural gullies, through the residential areas to Mudflat Creek. Mudflat Creek then travels through the rear of properties 37-63 Fraser Road before reaching the bridge in Noble Road and its outlet to Hardys Bay.

The recommended floodplain management measures for the Mudflat Creek catchment are summarised in Table ii in the summary report (The priority ranking is based upon a combination of reduction in flood risk, ease of implementation and cost/funding implications. There is no particular order of the measures within each priority categorisation).
