Ewest, I am steady being convinced that chemicals are in my future. It might be the best way to go due to the fact that the weeds are just beginning the invasion. The area of treatment will be relatively small. The shade idea is interesting. Where the trees shade the pond there is no current growth. I do not know if that would be a long term fix or not. With regards to the draw down. The pond is spring fed and would be very hard to draw down.
