RE:11/18 Indian Head
I believe the rule is "red spots == browns unless there are also blue spots == brookies" according to sea run rules, where the usual colors are missing from silver bright ocean trout. I'll have to check that but in Europe where the concern is atlantic smolt and grilse vs. salt browns, the rule is simply "red spots == brown".
My guess is that you caught a small sea run brown.
Were the fins wrinkled on top or worn on the concrete side of the tail?
BTW - I wish the source of the Indian Head had lower temps thru the season, it would be a searun factory! I fished it pretty hard in the coho salmon days.
