Caught this mature male(?) in central Idaho a few days ago. The coloration on him looks to me like he’s ready to spawn, but from what I understand cutthroat spawn in the spring. The second photo is a female(?) I caught a few minutes later out of the same hole. She was both longer and had more girth. Can anyone shed some light on westslope cut seasonal coloration? I know there’s a regional component here as well. They were caught in a small tributary stream to a large drainage. I’d say flows were 200-350cfs.
