The peak time in the 1%AEP Flood event on the Noosa River for the three river gauge sites is relatively similar.
For the evacuation procedures associated with this FEMP the Noosa River gauge site of specific interest is
the Tewantin Gauge, details of which can be seen in Table 3-2.

2.4          Site flood monitoring system
The site will be subject to flooding during large rainfall events for which Lake Weyba water levels rise in
response to severe downpours. There is the potential for failure (e.g. telecommunications or power failure) of
gauges. As a backup, it is proposed that flood height gauge and siren are to be installed to indicate depth to
residents of the site within the common property. This gauge will be installed to BOM specifications. This will
allow site specific flood monitoring in conjunction with reviewing the BOM weather warnings.
