We had a few problems that might skew our observations. We couldn’t smell anything. We could hear cars whizzing past us. We also saw a lot of leaves on the pond and around the pond, also there were 2 trees that had fallen into the pond. We were surprised because we didn’t expect to see trees in the water.

Too skinny!
You were looking for the right features, but fortunately the plant you found is only a partial match. I would more closely describe the leaves in your photo as elliptical, rather than feather divided. I'm also not seeing a plant that resembles a bottle brush or racoon tail.
Were there a lot of the same submerged plant in one place creating a dense mat of weeds? That would be a good indication of an invasion.
We have it too
We have a HUGE milfoil problem in Lake Arrowhead, especially in the Brown Brook area. Thankfully, we've taken steps to stop it.
