Spring flow into the Daly River totalled some 19 cumecs in September 2001, representing the largest groundwater input to the Daly/Katherine river system. Springs and seepages occur along the whole length of the traverse but major discharges and /or concentrations of springs were identified in some five discrete zones. Numerous springs are visible in the riverbanks but the majority of the inflow is via direct seepage into the riverbed. The main source of the springs is a fractured and cavernous aquifer in the upper part of the Oolloo Dolostone, a massive dolostone unit.

This report provides information on the geology along the Daly River, thereare also riverbed profiles and detailed tables containing information on chemicals, river temperature and pH levels.
