How the Flood Warning System Works

Don't wait for a flood to learn what to do. Know how the Flood Warning System works.

  • ABC Radio 91.7 FM - will provide regular advice and updates on the current situation during a flood.
  • If Tasmania Police and Council consider that Longford is at risk of major flooding and parts of the town must be evacuated, you will get a standby notice firstly from Council then told to leave your home by Tasmania Police.
  • Council staff monitor the warnings provided by the Bureau of Meteorology and also monitor river levels to predict the possible level of flooding.
  • The Bureau of Meteorology issues a flood watch when flood producing rain is expected to happen in the near future.
  • The Bureau issues a flood warning when flooding is occurring or is expected to occur.



There are three stages to a flood warning:

  • Minor Flooding - Low lying areas can be inundated which may require the removal of stock and equipment. Some roads may need to be closed.
  • Moderate Flooding - The evacuation of some houses may be required. Some traffic routes may be covered and roads closed.
  • Major Flooding - Properties are likely to be isolated and major traffic routes likely to be closed. Evacuation of people from the flood affected areas may be required.

 

Who To Contact For Current Flood Warnings

While Council will provide updates during a flood event within the municipality via media releases on ABC Radio 91.7 FM and on our website home page, it is also advisable to check the following links.

Erection Timing for the Longford Flood Levee Barriers

Union Street: If the River is forecasted to peak at a height of 6.7metres or above.

Lyttleton Street: If the forcast peak is a height of 7.3 metres or above.

Tannery Road: The height of the main entrance into Longford is 7.7 metres. Council will have the flood protection barrier prepared for erection if the flood is forcast to peak at over 7.3 metres but will wait as long as possible before closing the entrance to the town.

Archer Street: If the river is forecast to peak at a height of 8.3 metres or above.

Notes:
The actual height of these above mentioned flood levee opening is 0.4 to 0.5 metres higher than the levels at which the flood barriers will be erected.

In some circumstances Council may choose to install the barriers at lower river heights than those shown above, for example, if the river is expected to peak at night or if it is difficult to be certain about the expected height of the river.

Travel in Flood Conditions

  • The majority of flood-related deaths in Australia are a result of inexperienced people entering flood waters either in boats, vehichle or on foot. Avoid entering floodwater on foot or by vehicle, it may be deeper or faster flowing than you think, manhole covers may have come off and floodwaters contain hidden snags and debirs.
  • Don't walk on the riverbanks or across bridges if possible. They may have been damaged and might even collapse.
  • Don't swim in flood water - it is usually contaminated and often contains hidden snags, strong currents and other hazards.
  • Avoid wading, even in shallow water, for the above reasons.
  • If you must enter shallow water, wear rubber shoes or gumboots to protect feet. Don't proceed beyond waist depth unless absolutely necessary (and only if there is no obvious current).
  • Keep in contact with other people. Do things in pairs, do not go anywhere alone.
Important! Flood water is dangerous

Important Information in Comparing Historic Flood Levels

In comparing flood heights be aware the hydrological "landscape" of the South Esk River has changed significantly over the last 80 years. There is argument to suggest the volume of water in the 1969 flood was greater than the 1929, but the depth of flooding lower. This is just one of many complications in reading the record - depth or rainfall, location of rainfall, type of storm, antecedent conditions, depth of flow prior to flooding, physical changes in the landscape (willow clearing or planting, levees), degree of flooding in the Macquarie and Meander Rivers, etc, all influence the flood behaviour for each and every event.

Basically, it is difficult to compare one event to another. However, we can say the three events of 2011 are in the top ten, and that is significant. It is also significant the Meander River was not in Minor flood during the two large March and August events, else flooding would most likely have been more severe.
