Summer low flows


This summer continues to be relatively dry, as shown in the hydrograph above for the first half of September. The months of June and August have been especially dry as we can see for the precipitation data at Miomote (Amedas):

2012 Monthly Precipitation (with 1981-2010 mean)
June  59 mm (180)
July  201 mm (263)
August  81 mm (209)

No rain fell at all during the 18 days from July 26 to August 12, and the 13 days from 17-29 August. In fact the month of August recorded only 5 days with rainfall.

Stage = 41.5 cm, close to the minimum flow for the summer
