Yeah if the eagles weren't bad enough (there's three now) otters now patrol the shorelines (I think theres three or four of them). They're cool to watch but spook fish. They like to investigate my float tube. I had two of them swim up close and pop their heads up, checking me out. The eagles often pay more attention to the ducks and waterfowl than they do trout. But, they still follow me around when they see splashes near my tube. I've yet to lose a fish to one but they sure do spook me hovering right over my head.
