Hello, we hiked Swine Creek Reservation yesterday. We were sitting very quietly along the creek bank when we saw something move... when it moved away from the rocks, it ran up the hill (other side of the creek) . It really looked like a river otter since we have seen them in zoos before. However, I'm wondering if they are present in Swine Creek or if there is another animal that looks like a river otter? It was twice the size of a squirrel. We saw it alone. Also, wondering if otters would be by a creek. Thank you!
