This year I have had 2 moles, 2 chipmunks and 1 baby rabbit drown in my small, but deep pond. I have created a black, plastic net escape bridge and mounted it on the side to serve as a ladder to get out. So far, the baby bunny didn't figure it out. In other summers, I have also found floating box turtles, but they would probably not crawl up the bridge escape? Have you devised such an escape route? I mean, I HATE going out to gaze at my pond and finding dead fauna; too sad!
