River height readings are issued by the Burdekin Shire Council Flood Reporting Centre for various points along the Burdekin River with the main point for the Lower Burdekin being the gauge at the Burdekin Bridge at Carstairs, Home Hill.
Advance warnings of flood flows are provided by river height readings from Clare, Millaroo, Dalbeg and various stations further upstream.
The following table shows significant heights at the Burdekin Bridge and their probable effects in the Ayr and Home Hill areas.
In all cases, river heights are given as depths of flow above a fixed point of the stream bed (which was some years ago).
|Height at Burdekin Bridge in metres||Probable Effect|
6.00 to 7.00

The information contained in the Council’s Flood Reports relating to these effects, including predictions of effects at Rita Island and Groper Creek, are to provide guidance only.
