(Made me look) I was going to say "plants", which is what I have always heard, but then started wondering about the veracity of that, so I did look. This is what I found by on one website:
An example of evapotransporation is plants drawing down the amount of water in a stream by absorbing it through their roots. Infiltration occurs when water seeps down into the soil lining the streambed. The viscosity, or resistance to flow, of water is lower at higher temperatures, so the greatest amount of water seeps into the streambed during the hottest part of the day. This phenomenon is partly responsible for many desert rivers drying out long before the water reaches the sea; evapotranspiration does the rest.

Didnt think that there was that much viscosity present in water, but given the widely varied temps, seems to make sense (I guess)
