Waterlilies cope fine with a bit of splashing, flowing water.

Where they get into difficulty is when the foliage builds up some coverage, the constant splashing weakens the waxy waterproof coating off the top of the lilypad, the normal ageing process of the lilypad is accelerated, the superficial erosion allows the 'usual' decay by fungus which normally munch on the older lilypads to speed up

The creates a fertile brew for the more aggressive fungus such as Ramularia to establish, which can progress to damaging new foliage

Planting under the drip line of trees, fountains, very cool wet Summers, excessive lilypad coverage can get waterlilies sulking with fungus that cause superficial damage to lilypad foliage

The 'usual' fungus of decay won't kill the plant but can make a nasty looking mess of plants struggling to grow in adverse conditions
