Annual minimum flow

The annual minimum flow to date occurred on 24 September after a dry period of 5 days. Stage dropped to about 31 cm which is approximately 0.4 m3/s (0.0206 m3/s/km2) on the current stage-rating curve. A rainfall event of 37 mm around 25 September was enough to raise the baseflow level of the river by about 4 cm. This year's precipitation has been more evenly distributed than average which means that the annual minimum flow is also relatively high.
