For local rivers, I used to catch a few fish in the first half of December. Some were really nice fish, thick shouldered. Sometimes, I noticed they had a pink blush on the gill plates, even the does, but glowing chrome bodies. the last fish I caught before Christmas was twenty years ago. ...I have continued to hit a few around the New year, but not nearly as reliably in the last decade. The disappearance of early component sub populations in winter steelhead is fairly well-known. I used to even reliably catch coho at the end of august in a number of rivers and streams, but not for awhile. ....this is not counting known summer stocks like Capilano.
