Caught a 6" BG last week out of our pond with a strike mark that looked just like that. One side.
We have regular GBH visits when I'm not around. They go to the old pond when anyone is home or moving around. Have realized one shows up right at dark that may have been missing it being there.
Also have had cormorants on and off also. Only singles so far. Hope they don't decide to bring their buddies back.
