Flood

Flooding is part of life in Queensland and your home doesn't need to be flooded for you to be affected. 

We can’t prevent floods from happening, but we can take steps to be prepared.

What is a flood?

To put it simply, flooding is a when a normally dry area is covered in water. No two floods are the same, and different types of flooding can occur and vary depending on the quantity, duration and location of rain falling on our catchments. 

Flood impacts

Floods can have both positive and negative impacts.  While flooding can bring welcome relief for our farmers and ecosystems suffering from prolonged drought, they damage homes, communities, businesses, schools, roads and infrastructure, and even lead to loss of life. 

Flood types

Riverine flooding in Maryborough, Queensland
Riverine flooding
Riverine flooding happens when there’s been a lot of rain over several days or weeks. When there is too much water, creeks and rivers can burst their banks and that’s when flooding happens. In some parts of inland Queensland, riverine flooding can spread thousands of square kilometres for weeks or even months at a time. Related weather events include tropical cyclones, lows, monsoon troughs.
Flash flooding in Queensland

Flash flooding happens where there is a lot of rain in a short period of time. It can happen anywhere, at anytime, and often without a lot of warning. Flash flooding is dangerous. Expect to see powerful, water moving fast. In built up, urban areas, drains, creeks and rivers can fill up quickly and spread across nearby buildings, streets, roads and parks. Related weather events include severe storms.
Storm Surge in Whitsunday in Queensland
Storm surge and storm tide
Storm surge is sea water pushed onto land, often during a cyclone. Storm surges happen with the sea levels rise higher than normal tide levels. Storm tides are when the when storm surges happen alongside a high-tide. They can swamp low-lying areas, sometimes for kilometres inland. Strong winds at the coast can also make the impact worse by causing large waves. Related weather events include severe storms, tropical cyclones, low-pressure systems.

Know your risk of flood

To know the risk of flooding in your area, your best source of local information is your local council. Here are some questions you can ask to help you get started: 

  • What is the flood risk at my place? Where can I find this information?

  • Could my property be flooded? (Ask about ground level versus flood levels)

  • Could my house be flooded? (Ask about floor level versus flood level)

  • Could my street, suburb or locality be cut off by flood waters?

  • Where would I go if I needed to evacuate?

  • Which flood warning gauge is most relevant for me?

Make sure to check the flood risk for other locations that are important to you e.g. schools, work, relatives and any other places you regularly visit, considering safe potential evacuation routes and locations should you need to evacuate.
