We had the same problem only we lost the expensive plants and pond filter. Bizarre, they would rip up the filter and plants. We called the pond our 'raccoon spa'. We ended up turning it into a pondless waterfall feature. That's another story.
Raccoons like shallow water to wade in, etc. so if possible, make the pond deeper 1'+ and sharp drop edges into the pond; they're not into swimming if possible and if they can't walk directly in, they will likely look elsewhere.
