Cabbage Tree Creek - Flood Levels

On site investigation including interviews with local residents living in the precincts of the above creek were carried out with their observations of the creek flooding, together with comments in collating the information noted in this document.

It was apparent during observations and comments from the residents that the flood levels in Cabbage Tree Creek have an inconsistent gradient e.g. the recent flood dated 21st March 1983 was in some cases (Locations 8 and 12) 450mm lower than the previous highest, whilst in other locations (15, 16, 17 and 24) the height varied between 600mm and 3 metres lower than the previous highest in those areas.

In Location No. 27 the recent flood was a similar height to the previous highest. All this could be due to localised falls being heavier in some streets, debris choking the flow in certain sections of the creek or as most residents in the upper reaches agree due to the creek being either cleaned out and widened by Council or scoured by previous floods in their area. The latter appears to definitely have been the solution in the upper reaches.

Other factors in the recent flood being low in the downstream end of the creek appear to have been the improvement to the bridge on Montague Street and the fact that it was low tide at the peak of the downpour late in the afternoon.
