Description
This report summarises the nutrient and sediment loads and export coefficients measured at
the Bennett Creek, Elizabeth River, Berry Creek, Peel Creek and Moil Drain gauge stations
in the Darwin Harbour catchment during the period 2008-2012. Urbanisation increases the
amounts of these pollutants to the harbour, though their environmental impact depends on
their fate within the harbour environment.
Pollutant loads were mostly similar to previous years with the exception of the 2010/11 wet
season when the region received exceptionally high rainfall of between 2800 mm and
3300 mm, approximately double Darwin’s average annual rainfall. Pollutant loads in 2010/11
were the highest recorded at each of the three active stations due to high runoff volumes.,
