The Central Coast Local Government Area (LGA) in New South Wales includes several key townships such as Gosford, Wyong, and Terrigal. The region is characterised by its diverse landscape, ranging from coastal to hinterland regions, contributing to varying flood risks. The primary sources of flooding in the Central Coast LGA include heavy rainfall events affecting local creeks such as Wyong River, Ourimbah Creek, and Tuggerah Lake. These water bodies are prone to overflow during significant rain events, leading to widespread inundation, particularly in low-lying areas and floodplains. The coastal suburbs, including Woy Woy and The Entrance, are also susceptible to tidal influences and storm surges, exacerbating flooding during extreme weather conditions.
Flood management in the Central Coast LGA includes a network of levees, drainage systems, and flood mitigation projects aimed at reducing the impact of flooding on local communities. The Wyong River floodplain is a key focus area, with ongoing efforts to improve floodplain management and enhance early warning systems.
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.
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.
