Access online flood mapping tools to understand your own risk of flooding, and better prepare for the impacts of floods.
If you live in low lying areas or within a floodplain, it’s important to understand your own personal flood risks and have an up-to-date plan to ensure you are adequately prepared to respond to flood emergencies.
Online flood mapping tool
It’s not always possible to predict when, where, or how big the next flood will be. However, the likelihood of different sizes of floods and their consequences can be estimated by computer flood modelling.
Council's region-wide online mapping tool, provides a range of flood information on a visual map. Please refer to the fact sheet on definitions of flood mapping layers for further details.
Use this online mapping tool to understand your risk of flooding and how your property and surrounding streets may be impacted at various water levels.
Alternatively, contact Council to confirm if your property is within a potential floodplain.
For information on Council's management of coastal lagoons including water levels and intervention trigger information, see our coastal lagoon web page.
Rainfall and water level gauges
In total, there are currently 52 rainfall gauges and 41 water level gauges in operation on the Central Coast. They are owned by four different agencies including the Bureau of Meteorology (BoM), WaterNSW, the Department of Planning and Environment (DPE), as well as Central Coast Council.
Most of these gauges are managed on behalf of Central Coast Council by the NSW Government’s Manly Hydraulic Laboratory.

Plan and prepare for floods
We know that severe weather and other emergency events will continue to be a part of our lives on the Central Coast and that flooding occurs in our region.
View our planning for emergency web page for flood preparedness resources and more information.
Have you experienced flooding?
Council appreciates any information from the general public to help monitor flood issues on the Central Coast.
If you have experienced consistent minor flooding on or near your property which has originated from a local stormwater drain, natural stream or estuary please report it to Council.
This information is important to help identify new or repeated areas of flooding, assist with determining flood heights for future flood events, and to identify areas for priority investigation and potential works to alleviate the problems.
