Lotus and lilly pads are very different evolutionarily.
You're right! For some reason, I jumped to the conclusion that this thread had referenced "lotus", and not simply "lily". My bad - and yes, they're different from each other in many ways.
In general, I rarely encounter issues with most "lilies" that justify control-measures. However, watershield (Brasenia) is a different story - since it can overtake many ponds and small lakes under ideal conditions.
It's just a guess, but I'd bet that watershield is the "lily" referenced in this particular case. Photos would help confirm my hunch.
Kelly - I've got to ask - how long did it take to get in this condition?
In reference to the American lotus photos I posted; probably 4-5 years.
