I like the way you have it anchored, I was looking at it for keeping the leaves out of the pond. Well they aren't really leaves, and not pine needles but some twisted aberration that just dumps on the pond during fall, (ok so I have no idea what kind of a tree it is). I think the weave is too large for them, but I'm sure I can find a smaller weave and set it up the same way you have yours. I was originally trying to find a way to anchor a net higher off the ground to catch the leaves so I wouldn't have to move my pot fountain and some of the plants in the pond but may have no choice. I really do like your set up though, nice and clean.
Oh well, it's not going to get done this year but it's food for thought for next fall.
