Hello, sorry for the late reply and thanks for all of yours. To answer some of your questions:
The weed is currently growing in water from 18 inches to 4 foot. Its currently completely submerged and seems to be staying that way. Its growing with interconnecting roots which break off easily as individual plants. The water movement in the lake since Autumn has been low as the fountain is out for maintenance over winter. I'll try to get an in situ picture for you now. And apologies in advance as I'm doing all this on my phone! Thanks again.
