These are natural cycles. WSR will not change the ebb and flow of natural populations. Much more drastic swings in fish population get no managment response at all. Why this should be so big a deal is a mystery to me. Sure steelhead populations have declined for the past 5+ years but they only increaesd the 10 or so years before that. Neither has much to do with catch rates.

Besides if you are really so concerned about wild steelhead and fishing impacts, why not just close the spring fishing and let the fish spawn in peace?
