This brochure describes
the flood warning system operated by the Australian Government, Bureau
of Meteorology for the Bulloo 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.
The Bulloo River catchment is located in south west Queensland and covers an area of approximately 55,000 square kilometres. The river rises in the Gowan Range, 125 kilometres north of Adavale and is joined by its main northern tributary, Blackwater Creek, 20 kilometres below Adavale. Flowing in a southerly direction, the river passes through the catchment's only towns of Quilpie and Thargomindah, before entering sandy country on the Queensland-New South Wales border. Floods normally develop in the headwaters of the Bulloo River and Blackwater Creek, however, flooding can develop from heavy rainfall falling in the middle to lower reaches of the catchment below Quilpie.
The Bulloo River at Quilpie has well documented history of flooding dating back to 1950 with Thargomindah having records dating back to 1949. The flood of May 1989, 2010 and to a lesser extent the flood of April 1990, caused inundation of many properties in both the Quilpie and Thargomindah districts. The significant flood peaks at Quilpie and Thargomindah are shown in the figures below.
The Bureau of Meteorology operates a flood warning system for the Bulloo River basin based on a rainfall and river height observations network shown on the map. The network consists of a number of volunteer rainfall and river height observers who forward observations by telephone when the initial flood height has been exceeded at their station, as well as automatic telephone telemetry stations at Quilpie and Autumnvale which are operated by the Bureau of Meteorology, the Quilpie and Bulloo Shire Councils and the Department of Natural Resources and Mines.
The Bureau's Flood Warning Centre issues Flood Warnings and River Height Bulletins for the Bulloo River during flood events. Specific river height predictions are focussed on the main townships of Quilpie and Thargomindah.
The Quilpie and Bulloo Shire Councils may be able to provide further information on flooding in your area of the Bulloo River catchment.
Flood Warnings and Bulletins
The Bureau of Meteorology issues Flood Warnings and River Height Bulletins for the Bulloo River 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 :
Internet/World Wide Web
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 Bulloo River basin - it contains the flood gauge heights of the more significant recent floods.
Historical flood heights for all river stations in the Bulloo River Floodwarning network, as shown on the map, are available from the Bureau of Meteorology upon request.
At each flood warning river height station, the severity of flooding is described as minor, moderate or major according to the effects caused in the local area or in nearby downstream areas. Terms used in Flood Warnings are based on the following definitions.
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 Bulloo River catchment.
All heights are in metres on flood gauges. (B) = Bridge
