Nice little 13"er! Skinny due to not fully recovering from spawning yet, no doubt.
I've seen snaakier ones. Last month I caught a planted broodstock cutt in Lake Nahwatzel that was 17" long and the head probably outweighed the rest of it!. It was also pretty naive, as i kept missing its strikes until I finally hooked up. Then it didn't fight hardly at all.
I'll bet your 13" wild "snake" fought a lot better than than tired old spawner i released after a 15 second "battle."
