Fountains lose water through: surface area evaporation (surface area of a body of water is increased if water is being sprayed or falling), wind accelerating evaporation in airborne and still water, wind blowing water out of the fountain, children (and some adults ) playing in the fountain...rhino wrote:Rymill Park Lake I can understand - but the surface water area of a fountain cannot be compared to that. The water feature at the "Entrance to Adelaide" at the Tollgate Junction has a very small pool at the bottom - or are you saying that the water is evaporating as it is falling?loud wrote: Fountains actually suffer from a high level of evaporation and they are constantly needing to be topped up with fresh water. This is the same reason that the lake in Rymill Park has been filled in... because it is shallow and not a dense body of water, it too evaporates quickly.
From what i have read and heard, one of the other main reasons that fountains are shut down in drought conditions is to remind society that we are in a drought and to encourage us to conserve water.
