Flood Height Alert Review Flood Height Alert Review

The Bureau of Meteorology and Queensland Government has asked Council to review the flood levels for St George to more accurately reflect what is happening in our town.

The current levels at which emergency alerts begin are 4m for a minor flood, 5m for a moderate flood and 6m for a major flood. At 6m the Balonne River is still within its banks and is not a threat to our community.
It has been suggested the levels be changed to 6m for a minor flood, 8m for a moderate flood and 10m for a major flood.
The Bureau of Meteorology classifies floods as follows:
A minor flood causes inconvenience. Low-lying areas next to watercourses are inundated. Minor roads may be closed and low-level bridges submerged. In urban areas inundation may affect some backyards and buildings below the floor level as well as bicycle and pedestrian paths. In rural areas removal of stock and equipment may be required.
A moderate flood is in addition to the above, the area of inundation is more substantial. Main traffic routes may be affected. Some buildings may be affected above the floor level. Evacuation of flood affected areas may be required. In rural areas removal of stock is required.
A major flood is in addition to the above, extensive rural areas and/or urban areas are inundated. Many buildings may be affected above the floor level. Properties and towns are likely to be isolated and major rail and traffic routes closed. Evacuation of flood affected areas may be required. Utility services may be impacted.
