This was found in a man-made wetland/lake (Wallisville Lake Project by the Corps of Engineers). Has anyone seen anything like this before? Other plants found with it were a few different algae (thread algae mostly), mosquito fern, P. hydropiperoides, Alligatorweed, duckweed, and cattails. The glossy/oily film in the first pic is probably boat motor oil (this channel leads to a boating area).
