Daly River
The aim of this project is to contribute to recommendations on environmental flows to ensure that they are consistent with maintaining the biota of the Daly River, given competing demands of agriculture, recreation and tourism, conservation and Aboriginal culture. Our focus is on flow, connectivity and water temperatures.

23 Timing of Annual Maximum and Minimum Flow The month in which the peak high flow occurs varies from December through to May (Figure 6) and the month in which flow bottoms varies from June through to November (Figure 7). Thus there is very great variability in the seasonal timing of the high and low flow conditions, respectively.
