I fish the Sky also. I think that they do release fish through out the system. I caught a Steelhead out of the West Fork of the Foss River in July on a fly it was a 21" male. I kept it as my Granddaughter said that when you go fishing you never bring any home. I did this one time just to show her that I did catch them. That's quite a ways from the hatchery. Jim S.
