What's good eating? Raccoons? They might appear to wash their paws, but they are filthy, disease carrying rodents. I believe it's illegal to kill them, but I'd sure as hell trap them and give them to animal control.

I have a friend up in Mt. Washington who has a pond. All of his years there he has fought animals attacking his pond. Frankly, I'd have given up by now or put the pond inside a structure. The chain link he keeps over it ain't pretty.

Maybe try an electric cattle fence? That's a single wire that might not look too bad. You could double it back or even go around a few times as cattle fences run for long distances.

What is the simple thing people used to use? Like a Model T coil? I guess they can sit energized for hours on end w/o burning out. I'm not sure on that, just that you can power them with a battery or a small 12v charger. They put out a wallop. That ol' Rocky Raccoon will probably crap and piss all over the place. Be careful handling any waste.
