What is the hazard?

FloodA flood occurs when water inundates a normally dry land area. The retention of water is often due to excess rain occurring in low lying areas.

Flooding in the Moreton Bay Regional area can also occur when dam releases are necessary to control dam levels and maintain the integrity of the dam structure.

Flash flooding often results when a storm moves slowly, so that a small area receives most of the rain. The drainage and runoff characteristics on the ground can also determine the area of greatest impact.

There may be little or no warning for flash floods.

Flooding can also occur as a result of storm surge. Storm surge is a rapid rise in sea level which moves inland very quickly. It is like a rapidly rising tide and is usually associated with a tropical cyclone.

What should I do before a flood?

  • Determine if your home or business is in a flood prone area - view Council’s flood information to view maps detailing flood prone areas or to download a Flood Check Property Report.
  • Ensure you have an emergency plan, including a plan for evacuation and a fully stocked emergency kit.
  • Register for Council's emergency flood alerts through MoretonAlert.
  • Check with your insurance company about your type and level of flood cover.
  • Keep gutters and drainpipes clear.
  • Avoid storing chemicals or poisons in low lying areas.

What should I do when I hear a flood warning?

  • Listen to 612ABC, 101.5FM or 99.7FM for local weather advice and warnings.
  • Activate your emergency plan.
  • Keep your emergency kit handy.
  • Move vehicles, outdoor equipment, garbage, chemicals and poisons to higher ground.
  • Safeguard your pets and livestock.
  • Plan which indoor items you will raise or empty if water threatens your home (eg. freezers and fridges).
  • Maintain a watch on Council's road conditions report.

What do I do during a flood?

  • Determine if it is safe to stay in your home. If not, prepare to evacuate early while it is safe to do so.
  • Monitor current flood warnings and continue to listen to 612ABC, 101.5FM or 99.7FM for updates.
  • Avoid entering flood waters unless absolutely necessary.
  • Don’t allow children to play near or in flood waters or drains.
  • Don’t drive through flood water.

"If it's flooded, forget it" campaign

Queensland Fire and Emergency Service have launched a new campaign to discourage people from driving or entering in floodwaters:

What do I do if I need to evacuate?

The need to evacuate may result from your own decision or as a result of local evacuation advice.

You should always allow plenty of time to evacuate safely and assume you may not be able to return for several hours or even days.

The safest and most comfortable place to evacuate to is to friends or family who live on higher ground.

Evacuation centres

As a last resort, you may need to consider evacuating to a Council evacuation centre. It is important to establish which evacuation centres are open and the safest evacuation route to use.

For information about which centres are being used during an event, see evacuation centres or contact Council.

In some cases, other means of evacuation or shelter may be more appropriate and residents will be advised accordingly.

If you need to evacuate:

  • Stay tuned to 612ABC, 101.5FM or 99.7FM for local advice and warnings.
  • Ensure you have your emergency kit and warm clothing, essential medications, valuables, personal papers, mobile phone and charger, photos and mementos in a waterproof bag.
  • Raise furniture, clothing and valuables as high as possible.
  • Empty fridges and freezers and leave the doors open.
  • Turn off power, water and gas main supplies.
  • Place a strong plastic bag full of sand or earth in the toilet bowl, over shower and bath outlets and all laundry/bathroom drain holes to prevent back-flow of sewerage into your home.
  • Lock your home and take recommended evacuation routes out of the area (check the road condition report for information on road closures).
  • Confirm arrangements for pets and livestock.
  • Remember that evacuation centres do not allow, alcohol, weapons or pets.
  • Let someone know when you have reached a safe area.

What should I do after the flood?

  • Wait until authorities have declared an area safe before re-entering.
  • Do not enter your house before the water has fallen below floor level.
  • Check with electricity, gas and water authorities to determine whether supplies have been interrupted and are safe to be turned on by you.
  • Don’t use gas or electrical appliances which may have been affected until they have been checked for safety.
  • Boil tap water until supplies have been declared safe.
