Muskrats didn't bother my lilies. But here is what I observed. I don't use chemicals in my pond and so I try to manage it in a natural way. But I had spreading cattails really starting to worry me and I thought I might have to spray them as some of my pond friends do theirs. Then one day I saw a muskrat and finally four of them in my � acre pond. Before the season was over with they cleaned out all of my cattails and they left and didn't come back when the cattail food was gone. They never bothered my lilies. The downside is they do make some holes in my bermed pond but not enough to bother me. But I believe they will be back if my cattails become too thick again.
