In this study, the nutrient content of three rural streams and one urban drain in the Darwin region are examined. The aims of this study were to: • Record nutrient concentrations in the four waterways. • determine the proportions of nutrients available in soluble, and inorganic or particulate form. • determine differences in nutrient composition between baseflow and storm flow periods. • determine seasonal differences in nutrient fractionation. • compare nutrient contents of streams that drain catchments with different land uses and varying degrees of development.

Nutrient concentrations in four Darwin region streams 13 3.3.2 Particulate v. reactive P Filterable Reactive Phosphorus (FRP) accounted for 33% of total P in Berry Creek, 11.5% in the Elizabeth River and 28% in Bees Creek. In the Winnellie Drain, the proportion of FRP was highest with 46% (Table 6). All three rural catchments showed a trend for higher proportions of FRP during the early wet season while fractionation did not appear to change with season in the Winnellie Drain (Figure 5). FRP was below detectable levels from mid to late March onwards in both Bees Creek and the Elizabeth River.
