Wouldn't worry at all about beavers. Otters, on the other hand can be some mean SOB's
Never thought we had otters in our area, but we've had a bunch of trout killed in the pond and I knew the damn Eagles weren't killing them all as fast as the numbers were going down. Looked out the window and caught one running across the ice and disappearing down through the ice, only to come up with a trout. Pretty damn cool to watch actually.
