From that crappie picture, it is possible that stuff is Chara - a coarse branchy sometimes twiggy form of algae. It is possible it is 'small pondweed'. No one can see any structural details of the plant other than it is green. One cannot see any form of detailed structure in that compact "wad" of greenery to put an acurate name on it. Try again. Here is a link to how best take and present pictures of aquatic plants and algae.
