Longer-Interval Water Flow for Both Fountains for 2-day Period

This graph compares water flows from the high and low fountains for a continuous 2-day period (roughly noon Tuesday through noon Thursday). The base temperature measurement is of ambient air temperature at the water discharge spigot; when the fountain is used, however, the temperature of the sensor is affected by the colder water contacting the sensor. Dips in the graph below ambient temperature (which itself varies) indicate water flow (usage) events.

Question: There seems to be no clear diurnal pattern in water usage, why; is there a plausable reason for the lack of usage in the right third of the graph (a water boycott?); what is the ratio of use of the high versus the low fountain; what might cause the somewhat higher "at rest" temperature for the ADA versus the main fountain?
