Field Notes
We were happy to be outside and it was not raining. We could see ducks, water, sunny skies. We could hear people and traffic. It smelled earthy. Our prediction was that due to the lack of boat traffic and lack of the 11 most unwanted found in the area we felt that Rollo Pond was not as likely to have an invasive species.

We saw no evidence of tiny white flowers that should have been present in the month of August as you would find on Variable Watermilfoil.

I agree this does not look like a milfoil but it is difficult to see the leaves on the plant. The plant appears to be covered in algae.
