Looks like wild rice to me. Curly leaf pondweed? Yikes!, that is not a good hitchhiker. My least favorite pondweed, unlike American which has almost all of it's growth on the surface, that stuff is like freshwater seaweed or kelp, it has leaves from top to bottom. I have a 2 acre pond I would say is infested with it. When it draws down the stuff dies off bad, loads nutrients makes algae and the pond unsightly. One of those ponds where no herbicides as I have lilies and smartweed I want to keep. So I mow and rake and lift out big rope handled buckets full of the stuff. Get rid of that sooner than later.
