Deer Creek what are they

[Freakyfisherman]

Sonar can be frustrating at times. You can guess at times what is being on your screen. I was sharpshooting or open water ice fishing two summers ago on Deer creek from the float tube. I was so certain that I was marking walleye and sent down the jigging rap. Big mark chased it and I hooked into a big one. Golden toothless walleye( carp). So until you actually see with a camera or catch the fish, it could be anything.
