Late summer rains

Stage = 45.5cm, Ta = 20.8C, Tw = 16.6C

Today was another wet day for fieldwork, but we took the usual discharge measurement and inspected everything to check for any damage during the past 6 weeks. As you can see in the hydrograph below, the first two weeks of August were very dry, but since then there have been several rain storms and wet days. However, these events were not as large as the rain storms we had during July. A low flow of less than 40cm stage was recorded in mid-August, but this is not as low as the flows we had during June before the rainy season arrived. The record-setting rains during July have raised the groundwater levels so that we are unlikely to have very low flows this month.
