Flood Risk

Previous Flooding

Since records commenced in early 1900s, major floods have occurred regularly in the Herbert River. Major floods usually occur in the wet season from January to March, but smaller floods have occurred in April and December. The figure below shows the significant flood peaks which have occurred at the Ingham Pump Station and Gairloch.

Flood Forecasting

Local Information

The Hinchinbrook Shire Council and the Tablelands Regional Council are able to provide further information on flooding in your area of the Herbert River catchment.

Herbert ALERT System

Flood Warnings and Bulletins

The Bureau of Meteorology issues Flood Warnings and River Height Bulletins for the Herbert River catchment regularly during floods. They are sent to radio stations for broadcast, and to local Councils, emergency services and a large number of other agencies involved in managing flood response activities. Flood Warnings and River Height Bulletins are available via :

Local response organisations
These include the Councils, Police, and State Emergency Services in the local area. 

Internet/World Wide Web
Flood Warnings, River Height Bulletins and other weather related data is available on the Bureau's Web page at http://www.bom.gov.au . The Queensland Flood Warning Centre website is http://www.bom.gov.au/qld/flood/ .

Telephone Weather
Flood Warnings are available through a recorded voice retrieval system, along with a wide range of other weather related and climate information.

Interpreting Flood Warnings and River Height Bulletins

Flood Warnings and River Height Bulletins contain observed river heights for a selection of the river height monitoring locations. The time at which the river reading has been taken is given together with its tendency (e.g. rising, falling, steady or at its peak). The Flood Warnings may also contain predictions in the form of minor, moderate or major flooding for a period in the future. River Height Bulletins also give the height above or below the road bridge or causeway for each river station located near a road crossing. 

One of the simplest ways of understanding what the actual or predicted river height means is to compare the height given in the Warning or Bulletin with the height of previous floods at that location. 

The table below summarises the flood history of the Herbert River catchment - it contains the flood gauge heights of the more significant recent floods.

Historical flood heights for all river stations in the Herbert River Floodwarning network, as shown on the map, are available from the Bureau of Meteorology upon request.

Flood Classifications

The table below shows the flood classifications for selected river height stations in the Herbert River catchment. 

The above details are correct at the time of preparingthis document. Up-to-date flood classifications and other details for all flood warning stations in the network are at:
