Field Notes
The weather is nice and we get to work near and in the water. The pond thing is really smelly. We see the pond, plants, algae floating along the surface, and we saw the other groups rushing around. We are surprised that we found such large clumps of algae. The problem was that the was pond was quite murky, therefore we couldn't see the bottom or the plant life submerged.

Supporting Evidence

There is no steam, and Variable watermilfoil has a thick reddish brown steam.

There is no leaves. The milfoil has feather like leaves that are whorled.

The stuff we found was clumped together and milfoil grows in individual branches.

You're right, this specimen is not variableleaf water milfoil. It's not even a vascular plant. What your picture shows is a type of filimentous algae which is made up of microscopic plants that live in shallow water near shore or on submerged objects. For more information I suggest visiting the University of Maine's Field Guide to Aquatic Phenomona at: and checking out the "Stuff in the Water" tab.
Thanks for looking.
