Field Notes Sketch

I am happy because I'm helping collect data for science, and was helping find if there are any invasive plants in Milliken Mills.

I saw brownish water, lots of leaves in the water, trees, plants, birds, bugs, grass, dead trees and plants, frogs.

I smell fresh water.

I hear birds, the wind, and water splashing.

I am suprized by what I found or didn't find because even though it was an invasive species I thought I would find it.

Questions or problems I ran into were the weed weasel getting stuck on dead trees and branches in the water.

Supporting evidence
Photo of my evidence.

This is not Variable Watermilfoil because its community is emergent, and its leaves are oval.

The bottom of Milliken Mills Pond was almost completely clear of any plants.

Crystal clear

A clear lake bottom is usually a very good sign, and I would agree with you that you did not find milfoil. I would note however that milfoils do in fact have emergent parts, especially during flowering season when small spikes will protrude above the water's surface. Nice job!
