Does water evaporate in a fountain?
The lower the humidity, and higher the temperature, the faster water will evaporate. Also, the larger the fountain surface area covered with water, the faster the water in the basin will evaporate and need to be replaced. An outdoor fountain will evaporate faster than an indoor one.
