Bacchus Marsh Local Flood Guide
Are you at risk of flood?
Bacchus March is susceptible to flooding from rivers and creeks overflowing after prolonged rainfall (riverine flooding) and also to flash flooding after high intensity rainfall often associated with thunderstorms.
Riverine flooding in Bacchus Marsh is caused by flooding of the Werribee River. If the Lerderderg River floods at the same time as the Werribee River, then flood heights and impacts in Bacchus Marsh will be much greater.
In general, prolonged heavy rainfall over 12 hours or more will cause riverine flooding in Bacchus Marsh. Overflow from Pykes Creek Reservoir, upstream of Bacchus Marsh, can also increase flooding of the Werribee River.
During large riverine flood events, extensive flooding could occur in Bacchus Marsh, including Maddingley, the CBD, the Avenue of Honour and Woolpack Road areas. The roads to Werribee and Geelong may also be affected.
Flooding tends to be deeper south of the Werribee River. Flash flooding in Bacchus Marsh typically affects urban areas in Bacchus Marsh, Darley and Maddingley. This generally results from short duration, high intensity rainfall of approximately 15-20 millimetres in 30 minutes. There are many low-lying areas which may be subject to flash flooding.
