It is still REALLY early for springers down here. I am not sure about one on the Cowlitz I would have to see it to believe it, last year they were late. They are expecting huge runs. I would wait at least another three weeks before hitting it to hard. I do have 40 some odd packs of green and blue label ready to go. I have only had reports of like 8 caught below I5, credible reports though.
I have been using barbless hooks already, if you know what your doing it won't make any difference. Plus you can still use trebbles.
