Flood, storm and tsunami (natural hazards) can happen at any time in NSW. It is important to be aware of the risks in your area to help you to plan, prepare, respond and recover effectively. Understanding past and potential future hazards in your area helps you to make informed decisions that can reduce the impact on individuals, families, businesses and communities.
The local information page provides valuable resources for your Local Government Area (LGA). You can explore flood information for your local river catchment through Local Flood Insights, access local flood plans and guides, and connect with local councils and NSW SES units.
Parramatta River Catchment Flooding
The Parramatta River begins at the confluence for Toongabbie Creek and Darling Mills Creek and runs through the City of Parramatta, Canada Bay, Ryde, Hunters Hill and Inner West LGAs.
Flooding along the Parramatta River can happen because of heavy rain. The lower part of the river is tidal and can experience flooding when high tides coincide with heavy rainfall.
The Bureau of Meteorology does not have any river warning gauges along the Parramatta River.
The City of Parramatta is prone to flash floods. The City of Parramatta provides an early warning service for the Upper Parramatta River within the City of Parramatta. You can sign up for Flood Warnings through FloodSmart Parramatta.
Hawkesbury-Nepean Catchment
This local government area is part of the Hawkesbury-Nepean Catchment area.
The Hawkesbury-Nepean Valley covers a wide area in Western Sydney from Bents Basin near Wallacia to the Brooklyn Bridge. The area has a long history of dangerous and deep flooding.
The unique geography in the valley affects the extent and depth of flooding in the region. Most river valleys tend to widen as they approach the sea. The opposite is the case in the Hawkesbury-Nepean Valley, which means floodwaters flow into the valley more quickly than they can flow out, causing them to back up and rise rapidly.
If you live or work in an area with risk of flood, your home, family and animals may be vulnerable. It's important to always be prepared for floods in the Hawkesbury-Nepean Valley as floods can happen anytime. Use the interactive flood mapping tool which allows you to check your flood risk and provide information at a suburb level. For more detailed information on risk related to your property or street, please contact your local council.
