I don't know what all I have for pond flora. I have a dozen dams that are .5 to 6 acres that all winter killed 2 years ago. Crayfish are in most of the dams that is it. I have shoreline rush grass and then typical moss in the middle of the summer. I probably should know my aquatic species better but I was a range science major and only had to know how to identify the grass's above water.
