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.

55 to the longer-term variations and for the diurnal fluctuations. In the expanded section of the record shown in Fig. 32, the amplitude of the diurnal fluctuations is well represented for the whole of the two week piece of record shown although the daily averaged 'background' model temperatures are ~0.5 0C too high for the first few days and are a little low near the end of this data section. Figure 31 shows that the model underestimated the amplitude of the diurnal fluctuations by ~0.5 0C and the background temperatures by half this amount from the first week of August onwards. The degree of agreement between measured and modelled temperatures for Cattle Creek was similar to that demonstrated for Jinduckin Creek.
