SES has developed Local Flood Guides to explain local flood risks for communities at risk. This includes advice for communities on how to prepare and respond to flood events and who to contact in the event of a flood.
SES has also developed Municipal Flood Emergency Plans to prepare, respond to and recover from flood events within the Municipality.
Large severe floods within the Municipality generally occur as a result of a moist warm airflow from northern Australia bringing moderate to heavy rainfall over a period of 12 hours or more following a prolonged period of general rainfall. The period of general rainfall “wets up” the catchments and (partially) fills both the on-stream dams and the natural floodplain storage. These combine to increase the runoff generated during the subsequent period of heavy rainfall.
Short duration, high intensity rainfall (usually associated with thunderstorms) can also cause localised flooding within the municipality along overland flow paths when the local urban drainage system surcharges. Such events, which are mainly confined to the summer months, do not generally create widespread flooding since they only last for a short time and affect limited areas. Flooding from these storms occur with little warning and localised damage can be severe.
Significant flooding has occurred within the council area in February 2005 and most recently in May 2012 from Kororoit Creek, Brooklyn Creek and Spotswood Creek.
Households and business should refer to their local Flood Emergency Plan for more information.
