This past weekend we were sitting overlooking the lake and saw a fairly large mammal swimming between our docks. It was swimming with it’s head above water and dove several times. It appeared to be roughly 4′ long and had a slender body.
It was definitely not a muskrat or mink as it was much bigger.
It was not a beaver as it was longer and more slender, and I didn’t see a beaver tail when it dove.
I’ve never seen an otter in our lake, but I have read that they’re making a comeback. Is there anything else it could be that I’m not thinking of?
