Medium and high flows
The thresholds developed for the medium and high flows are reported in Table 3. The requirement to base these thresholds on non-zero flow was due to the proportion of zero flows being greater than 50% of the flow in some zones (Duck Ponds Creek and Stone Chimney Creek under the modelled current scenario) and close to the low flow threshold identified in other zones (Lower Flaxman, Angaston Creek etc.).
