access to the site. At monitoring site B8, samples were collected and analysed from 3 of 12
sampling events. B8 is located within an ephemeral section of the Creek and only contains
surface water when it rains or immediately following rain. This prevented the collection of water
quality samples and was the reason for the absence of water quality parameter
concentrations.

   5.1       Climatic Conditions
   Long-term rainfall and temperature data were collected from the SILO Climate Data 1 within
   the monitoring area for the Burgess Creek Water Quality Monitoring Program at the
   following coordinate location:
         •    Latitude: -26.40 degrees south.
         •    Longitude: 153.10 degrees east.

   SILO represents a gridded dataset based on records provided by the Bureau of
   Meteorology (BoM). The data is then processed to fill gaps in data and produce a spatially
   complete dataset (Queensland Government, 2021). A summary of monthly averages of the
   SILO long-term data is in Figure 5 and Figure 6. The following general trends were
   observed in the SILO data:

         • Higher monthly rainfall averages during January, March, April, November, and
              December, the "Wet Season".

         • Lower mean monthly rainfall between May through to October, the "Dry Season".

         • In 2021, the total rainfall record from SILO was 1613.40mm, compared to
              2014.90mm of rainfall in 2020.
         • Rainfall received in 2021 was below the long-term average annual rainfall of
              1771.82mm recorded since 2010.
