New water year brings autumn rains

27 Nov: Runoff is 6.45 mm/day

In the hydrograph below you can clearly see the low flow at the end of September is followed by a major runoff event in early October which raises the baseflow for the rest of the month and into November. This is typical for increasing precipitation and falling ET to lead to higher baseflows into autumn. October monthly runoff (151 mm) is more than three times larger than that for September (46 mm).
