My pond is built over a drainage channel or small stream and there are lots of ponds sort-of connected to it, many of them quite large, on undeveloped land, or both. Lots of places it could have come from. Downstream a quarter mile or so there's a mud hole full of beavers and nutria.
The local raccoons are still pulling mussels out of the pond so I assume otters haven't been here long. Need to get him quick.
