Squeeky-I have otter also in my lake. The first one that I saw was sitting on his hind legs holding a big bass like corn on the cob. I then saw others swimming in groups of four or five. My research suggested that they can destroy a lake's fish population. I contacted a trapper and in no time we are down four otter (and a couple of beaver). They can be live trapped too. I have a contact if you are near east Texas.
