Just to throw a wrench into the SR/WR discussion. Down on some Oregon river where they trapped upstream migrants 365 days a year they had winter steelhead returning in all 12 months. Maybe only 1 or 2 in late summer/fall. I think Smalma mentioned that some Skagit Winters spawn in July and maybe even early August so just because it was a wild fish in the summer doesn't make it a summer.
