The aim of this study was to undertake a preliminary analysis of groundwater fed flow data. The objective was to develop relationships between rainfall and groundwater fed flows that could be used to predict dry season flows in the absence of detailed low flow gaugings. Good long term daily rainfall data is available for Katherine. The area studied was the Daly Basin with a specific emphasis on the Daly River, the Katherine River, the Flora River and the Douglas River.
The report covers flow rates in the Daly River, it looks at the relationship between rainfall and potential recharge in the Katherine Region and also the relationship between estimated recharge and groundwater fed baseflows for the Katherine River at the Low Level crossing.
