Field Notes
It was a warm and sunny day. We could hear highway noise and see vehicles passing on the opposite side of the site. There was an athletic field in view to the right, surrounding grass was likely cut within the last 3 days. Many trees and vegetation around. Birch and perhaps willow trees. 15 to 20 degree pitch down to waters edge. No flowers present.
Supporting Evidence

Hydrilla is catagorized as having eight leaves per whorl. The species we found has exactly three leaves per whorl.
Photo of my evidence.
Leaves of the Hydrilla are blade like and toothed. The leaves on our sample were smooth to the naked eye.

Hydrilla is an invasive species and would be prevalent if found. The sample we pulled only had 3 pieces along with native grass.

I remembered seeing a post that was also a "NOT FOUND" hydrilla post that looked similar to your sample. http://vitalsignsme.org/species-hydrilla-verticillata-was-not-found-eyes...
