I did a survey this year, asking guide friends, how big is the biggest trout in the Truckee?
The guess, (because no one catches the biggest fish) is 30-32".
24"-26" are fairly common. So MP called it for this area, 28"+.
Difficulty in landing a fish factors in for me, not just size.
It's the size of the game in the fish, not the size of the fish in the game.
It really is relative to the size of the water. A 10" Brookie or Golden, in a creek you can step across, is a trophy.
Personally, I feel they are all trophies, and they all go free.
Cute little client fish from this Spring.
