esshup,
thanks for the reply. the ponds are on some property i own and i can't get there until next week to take better pics with a camera. the plants don't concern me as much as the FA. i think i remeber reading that liilies are invasive and to be avoided but they sure look good in a pond and seem like they would provide good habitat, oxygen and shade to help control FA in the shallows.
i will try to pm the pic to see if that works better.
