The objectives of this study were to investigate whether high nitrate concentrations were present in the Douglas River in the 2004 dry season, measure dry season flows of the Douglas River, determine nutrient loads of the Douglas and Daly Rivers, determine how the nitrate-rich Douglas River mixes with the Daly River and examine if this nutrient enrichment has an effect on phytoplankton in the Daly River.
