Brother wanted to keep his fishing spot secret. I'm lucky I got a state. 🤣
Sucker is my best guess. I don’t know much about fish, but there were hundreds of these in a sunny patch of the little cannon river. Had downward facing mouths
There are a couple more pictures of the fish with the common merganser observation: https://www.inaturalist.org/observations/143266334
Massive 14” Black Crappie caught with hook and line while fishing. He was sitting right next to the vertical drop created by the sidewalk seen in the back of the pictures. Safely released back into the lake!
