Thanks for the reply's guys. I only know of a few plants that grow in are area lakes and that's hydrilla, coon tail and lilly pads. Don't know if any of those other than the lilly pads that would grow in the pond and afraid they would take over. same thing with cattails wouldn't mind them in the upper end but don't want to many. What are some plant species you would recommend I look into. Or a book that may explain it.
