Denis - See if you can get some better photos of the lilies. There are several types of aquatic lilies, and I�d like to know the specific species that is inhabiting your pond.
Also, you mentioned having coontail in addition to the milfoil, but I�ve only seen your photo of milfoil.
Are you absolutely certain that coontail is also present � and posing an issue?
Can you collect a sample and take a photo of it in your hand, just so we can verify its ID?
I saw where you�ve owned the pond for roughly 4 years at this point. Historical imagery indicates that the pond was dry in and around the period ranging from 2004 � 2007 (maybe earlier and later). It filled (again) at some point between 2007 and 2010. It�s tough to define the south shoreline due to tree-overhang, but my remote measurements put the pond at closer to 3 surface-acres.
I�d like to hold off on any potential treatment suggestions until the lilies are IDed, and the presence of coontail is confirmed.
