Flooding

Understand how to prepare for, manage, and recover from floods.

The impacts of climate change will make intense summer storms more common and severe. Intense summer storms can cause floods. Floods are Australia’s costliest disaster.

What causes flooding

Floods occur when water catchments exceed their volume, or rain collects on non-porous surfaces. The extent depends on the:

  • amount and length of the rainfall
  • catchment volume
  • groundcover's ability to absorb water.

Impacts and effects

Floods can cause:

  • distress and anxiety
  • need for medical and wellbeing services to rise
  • destruction of buildings and community facilities
  • soil erosion, water pollution and animal and plant species to decline
  • services such as power, businesses, and supply networks to stop
  • the economy to decline because of these impacts
  • people to become displaced
  • the demand for building supplies and housing to increase.

Who is most at risk

The ACT Flood Prone area map shows areas that are at highest risk of flooding.

People who can’t leave their homes easily are at highest risk.

Before a flood

Stay in touch with friends, neighbours, and loved ones. If you need assistance, reach out to your contacts list. Let someone know if you plan to evacuate and where you intend to shelter.

Stay safe

Prepare early to leave if your property is at threat:

  • Check your home emergency kit. Add last minute items such as important documents, medication, and clean drinking water.
  • Decide where you will evacuate to. Evacuation centres should be a last resort. Plan to stay with family or friends if you can.
  • Pack food, water and bedding for your animals. Secure them safely. Check that they are wearing identification.

If you need to leave:

  • Use your cars hazard lights.
  • Keep clear of floodwaters.
  • Avoid fallen powerlines and debris near them. These could be live and cause an electric shock.

After a flood

Identify the impacts

Check on loved ones and assess damage to your property.

Manage ongoing risks

Watch out for potential risks.

  • If you have broken utilities, turn them off and let someone know.
  • Stay clear of fallen power lines and debris near them. These could be live and cause an electric shock.
  • If you see a tree on public land damaged, report it.
  • If you notice damage to a tree on your land, contact an arborist.
  • If your home is unsafe call the ACT State Emergency Service for help.
  • Avoid waterways. After a flood the water runoff can move fast and might have pollutants and other debris in it.
  • Get assistance for your mental health if you need it.
