This brochure describes the flood warning system operated by the Australian Government, Bureau of Meteorology for the Haughton River. It includes reference information which will be useful for understanding Flood Warnings and River Height Bulletins issued by the Bureau's Flood Warning Centre during periods of high rainfall and flooding.

Flood Risk

The Haughton River catchment covers an area of approximately 1850 square kilometres and includes the major tributaries, Reid River and Major Creek. Barratta Creek is the overflow for both the Haughton and Burdekin Rivers. The headwaters of the Haughton catchment rise in the Hervey Range. As this is a relatively small catchment and due to the rapid response of the catchment to rainfall, travel times are very short. Heavy rainfalls over the catchment are capable of causing major flooding of agricultural areas adjacent to the waterways and major flooding of residential and commercial areas in Giru. The township has a levee constructed around the town to protect it from floods up to about 2.30 metres on the flood gauge.

Previous Flooding

Flood records for Giru only go back to 1978. The highest flood on record occurred in February 2011 with a recorded peak height of 3.09 metres on the flood gauge, causing widespread inundation of the Giru township.

Flood Forecasting

The Burdekin Shire Council, in conjunction with the Bureau of Meteorology operates a flood warning system for the Haughton River catchment. The ALERT network consists of automatic rainfall and river height stations which regularly forward data via radio telemetry to a base station located at the Council office in Ayr and the Bureau's Flood Warning Centre in Brisbane. The system provides early warning of heavy rainfall and river rises in the catchment and enables more accurate and timely flood warning and forecasts. The balance of the network consists of volunteer rainfall and river height observers, who forward observations by telephone when the initial flood height has been exceeded at their station. The Queensland Department of Environment and Resource Management also operates a number of automatic telephone telemetry stations throughout the catchment. 

The Bureau's Flood Warning Centre issues Flood Warnings and River Height Bulletins for the Haughton River catchment during flood events. Quantitative flood forecasts are issued when moderate flood levels are likely to be exceeded at Giru, with an objective to provide between 3 and 12 hours warning of these flood levels.

Local Information

The Burdekin Shire Council is able to provide further information on flooding in your area of the Haughton River catchment. 

Haughton ALERT System

The Haughton ALERT Flood Warning System was completed in 1993 as a co-operative project between the Bureau of Meteorology and the then Thuringowa City Council. The system, now transferred to Burdekin Shire Council, comprises of a network of rainfall and river height stations which report via VHF radio to a base station computer located in the Council office in Ayr. The stations send reports for every 1 millimetre of rainfall and every 50 millimetre change in river height. 

In consultation with the Burdekin Shire Council, the Bureau issues Flood Warnings for the Haughton River. 

The base station computer in the Burdekin Shire Council office collects the data and has software that displays it in graphical and tabular form. This data is also received by the Bureau's Flood Warning Centre where it is used in hydrologic models to produce river height predictions. 

Flood Warnings and Bulletins

The Bureau of Meteorology issues Flood Warnings and River Height Bulletins for the Haughton 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 :

Radio stations, particularly the local ABC, and local commercial stations, broadcast Flood Warnings and River Height Bulletins soon after issue.

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

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 Haughton River catchment - it contains the flood gauge heights of the more significant recent floods.

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


Major flooding requires a large scale rainfall situation over the Haughton River catchment. However, the following can be used as a rough guide to the likelihood of flooding in the catchment:

Average catchment rainfalls of in excess of 200mm in 24 hours may cause moderate to major flooding and traffic disabilities to develop, particularly in low-lying areas of the Haughton River catchment downstream of Hustons Farm, extending into the Giru township and Haughton River delta area. 

Average catchment rainfalls of in excess of 300mm in 24 hours may cause major flooding and traffic disabilities to develop, particularly in low-lying areas of the Haughton River catchment downstream of Hustons Farm, extending into the Giru township and Haughton River delta area.

Flood Classifications

[an error occurred while processing this directive]
Each river height station has a pre-determined flood classification which details heights on gauges at which minor, moderate and major flooding commences. Other flood heights may also be defined which indicate at what height the local road crossing or town becomes affected by floodwaters. 

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

River Height Station
First Report Height
Crossing Height
Minor Flood Level
Crops & Grazing
Moderate Flood Level
Towns and Houses
Major Flood Level
Flora Valley 3.0 12.0 (B) 5.0 5.0 5.5 5.0 6.0
Mt Piccaninny 3.0  - 4.0 5.0
Major Creek - 7.0 - 8.0 - 9.5
Powerline 5.0  - 6.0 - 8.0
Hustons Farm 3.0  6.1 (B) 4.0 4.0 5.0 4.6 6.7
Giru 1.0  3.5 (B)  1.8  - 2.1 2.5  2.5
 All heights are in metres on flood gauges.
