Careel Creek
Watercourse
Where does it flow to?

When has it flooded in the past?
1973, 1975, 1984, 1987, 1989, 1990, 1997, 1998, 2008
How many properties are flood affected?
Approximately 410, with about 180 properties (both residential and commercial) flooded above floor level in a 1%AEP flood event.
What are the flood risks?
- Flooding can occur from flash flooding from the creek after heavy rainfall in the catchment or from waves and king tides from the Pittwater Estuary during a severe ocean storm or a combination of both.
- Flash flooding means that flooding will occur quickly and there will be little opportunity for warning or assistance before or during a flood.
What is Council doing?
- Careel Creek Drainage Catchment Flood Study (Lawson and Treloar, 1999) was adopted by Council in June 2000.

What can I do?
- Being prepared for a flood is the best way to reduce the risks. The State Emergency Service (SES) is the lead response agency for floods, storms and tsunami across NSW. See the SES website for ways you can prepare for a flood.
- Council will post information on the website and advertise in the local media whenever new information becomes available
