My thoughts were it wasn't from this year either and that's good to get some confirmation. I have no clue how this could have ended up in the pond other than someone placing it there. Which is always fun since it's on private property (time to put up a trail camera). At the same time, I don't know why anyone would dump that size fish into a private pond even if they're poaching/trespassing.
The pond is ground water fed, no streams going into it. I did stock more HSB this spring, but I hand sorted each and every single fish put into the pond. I remember because I tossed out a few that looked unhealthy to me.
