Adding Water lillies to a fresh water pond with natural springs feeding it

Doug says that if the water is cold - you may not have too much of an issue - they prefer warmer water. If they do grow excessively, then you simply dig some of them up. Or you control them by pulling up the extra growth you don't want.
As for what you need to know - if you like then - go for it (you can control with a bit of effort) but if you don't want to be bothered controlling the growth and you like the look of your pond, then I'd pass on the plants.
Me? I love waterlilies because they're really easy to grow - plant and ignore. But they do spread if happy and do require some cleaning (and will die in winter to leave organic matter on bottom of pond)
Not sure if that's what you need to know but hope it helps a bit.
