Floods

Flood-web-banner 
Floods can occur at any time in Australia and across the Rockhampton Region; however, the period that floods are most likely is between November and April.

Floods occur when water covers land which is normally dry and may result from prolonged or heavy rainfall. There are different types of flooding including:

  • Riverine flooding caused by widespread, prolonged rainfall over the catchment area
  • Creek flooding caused by significant rainfall resulting in flash flooding
  • Stormwater overland flow flooding during and after heavy rain when water flows across the ground or rises naturally from underground and
  • Storm tide flooding caused when a storm surge creates higher than normal sea levels. 

Rockhampton Regional Council is a full member of the Floodplain Management Association.

Flood Warnings

Flood warnings are issued by Australia's national weather, climate and water agency, the Bureau of Meteorology (BoM).  There are three levels of flood warnings.

Minor flooding – Causes inconvenience such as closure of minor local roads and low bridges.
Moderate flooding – Low lying areas will be inundated requiring removal of stock, equipment and evacuation of homes.  Some major roads or access points may be covered.
Major flooding – Higher areas will be inundated with isolation of towns and properties causing extensive damage.

Flood Level Classifications

The Fitzroy River catchment, due to its immense size and shape, is capable of producing severe flooding following heavy rainfall events. The Rockhampton Region has been affected by regular floods across recorded history. Major flooding from the Fitzroy River in 1991, 2011 and again in 2013 has had devastating impacts on the local community and resulted in significant impacts to the local, state and national economy.

Be prepared

To be prepared in the event of a flood, remove as many household items as possible (including cardboard boxes and newspaper items) to as high a point as possible; pile furniture on beds and personal items on the furniture; remove all drawers from built-ins; tie down loose items in your yard; ensure all chemicals that may react with water are within a water proof container and are moved to a higher level; gas cylinders and gas bottles should be disconnected and tied down or removed above flood height and close the main water valve.

The following resources are available to help residents be prepared for flood season:

Flood Resilience

Council aims to improve the community’s flood resilience through building its understanding of flood behaviour and associated risks.

The Flood Management Strategy(PDF, 23MB) details the background of Council’s flood management activities, explains our holistic and integrated flood management approach, and provides an introduction to future flood management objectives. This document outlines how Council intends to work towards improving future flood preparation, response and recovery.
