Sorry to hear about the demise of the South Fork's steelhead. There used to be a small native run of summer steelhead in Canyon Creek, but the fish that were introduced above there were Skamania stock (in fact I think they were also stocked in Canyon Creek itelf), the same fish that are stocked on the North Fork above Deer Creek. There are still good numbers of sea-run cutthroat in the lower part of the river.
