Good video of your lake. At 50-80 acres, I would call that a small lake although it is technically a large pond.
Plants- I'm not positive as to what they are. The ones with the white 'stems'; are the white parts roots or stem-leaves on the bottom side? It is very hard to identify aquatic plants when they are held all bunched and matted together. Get us some better pictures - see examples in the link.
