there was a couple on one of the lakes i fish for a summer. i figure they got in traps, or moved on, because they disappeared. shame, they are neat critters! make their squeaking sound and see what they do. i had one standing on a log next to my boat. was kinda wondering what would have happened if he jumped in. they seem friendly enough, but my fingers smelled like fish. lol i had the same thing happen with a beaver. she was huge and freaking me out a little because she had been slapping/splashing at me to leave her area.
