Field Notes
The last day of school I learned about Invasive Aquatic Plants and they said if the plant has three or more leaflets it may be a red flag. This plant (Variable Milfoil) had five leaflets.Lake Arrowhead was also known for Variable Milfoil which spread all over the lake causing a threat to Little Ossipee (another lake about 25 feet away).
Supporting Evidence

The Variable Milfoil has five leaflets and Native plants usually have three or less.

Comments

Your id is likely correct since Lake Arrowhead is heavily infested with variable leaf milfoil. All but one of Maine's native milfoils have three or more leaves arranged in a whorl around the stem, just like this invasive. The only definitive way to identify a milfoil plant is to find one while it's in flower because each species of milfoil has a different flowering structure.
Nice find.

Thanks! I had studied aquatic plants for six hours on the last day of school!

Thanks for keeping an eye out for those pesky aquatic invasives. Did you find this floating on the shore of the lake?

I found this on the edge of the shore and I decided to test out my learning skills from the six hour training!
