I have observed and have had to live through these flood incursions on numerous
occasions in the more than 11 years that I have lived here. The comments I am about to
make are based on my observations of the numerous flood events that have occurred in
that time.
Essentially, the changes that I have already mentioned dam the floodwaters and the
water backs up into my property. There is a "threshold level" to the flooding. The road and
poor drainage under it act as that threshold level and backs up water into my property.
Water is pooled on my property. My property has effectively become the equivalent of a
flood mitigation dam for the property across the road. Lesser flooding means that the
floodwater is dammed in my property by the raised road profile and the inability of the
drains under the road to convey the volume of water. This pooling of water is clearly
evidenced by the fact that firew~od and other wooden items have been lifted by floods and
when the floodwaters recede they have been left stranded closer to my house (uphill). In
effect, the confluence of the natural meeting of the two creeks has been moved from the
Wimmers property into mine through the damming effects that occur.
By the time that the water gets over the level of the road, the narrow, steep man-
made courses for the creeks in the Wimmers property cannot effectively handle the volume
of water. All other soil profiles on the other side of the road in the Wimmers property have
clearly been modified from their original levels. Even though the other side of the road (the
Wimmers property) is downstream of my property, the huge majority of it has been made
to be higher than the land that is on my corresponding side of road. (Soil testing, comparing
the soil on my side of the road to that on the Wimmers property side of the road may
possibly confirm the extent and depth of any modifications that have been made.) This is
especially so in the areas that are accessed through the gates currently marked as gate 3
and gate 4. There is no sign of the natural shape, history or levels of the watercourse. There
are no signs of the flood terracing or meander scars that are clearly in evidence on my
property and on the other properties through which the two arms of the creek flow.
An attempt has been made to contain the arms of the creek in steep-sided drains on
the Wimmers property. This has failed on numerous occasions and flood waters have
regularly spread out also over the areas at gates 3 and 4. The past tenant of the Wimmers
property has clearly raised low lying land in an attempt to make it more flood-proof and
more usable to them. This however has in effect appeared to have added to the damming
effects of the road. It appears to slow the flow (escape)of water and also then to contribute
to and cause the high level of flooding on my property experiences.
Before I bought the block of land that I have built on, I contacted the Noosa Council
by phone and was told that the whole block was above the hundred year flood line. This has
proven to be dangerously wrong on a number of worrying occasions. The knowledge of
flood level history and threat, as is reflected in the information in the Noosa Plan, by Council
was (is) seriously flawed.
