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.
Southern Grampians Shire Council has a number of creeks, rivers and other waterways that are at risk of flooding as well as a number of areas that are at risk of flash flooding from heavy rainfall occurring in a short period of time.
Historic flooding events include 1946, 1981, 1983, 2010 and 2011. The 1946 flood is still considered the largest in recorded history with many flood level records being broken during this event. The flood event in 1983 is also a large flood for the area. During the floods, Hamilton, Coleraine, Branxholme and a large portion of the Wannon River from Henty to the shire boundary have been affected by flooding.
Households and business should refer to their Local Flood Guide or Municipal Flood Emergency Plan for more information.
