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 Municipality.

Flood history

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 or more hours following a prolonged period of general rainfall. The general rainfall 'wets up' the catchments and partially fills both the on-stream dams and the natural flood plain storage.

These combine to increase run-off generated during the subsequent period of heavy rainfall.

Riverine flooding of the Diamond Creek, Plenty River, Wilsons Creek, and Yarra River have historically caused issues for the shire.

Households and business should refer to their Local Flood Guide or Municipal Flood Emergency Plan for more information.
