The radio tagging was done in 2000 I believe, 20 years ago already yikes.
I've asked Mike to comment on it. Also, he wants me to share this chart with everyone. This is the river's catch and effort on steelhead based on the steelhead questionnaire people mail back.

Number of angling days per fish caught have not changed over the years, therefore they believe increasing the daily quota to two would not change angling pressure.
My concern isn’t that we’d see a surge of anglers or angling days if we change the daily quota, but more how much more time anglers would spend on the waters when they are out on any particular day. Current reg means they’d get their hatchery fish, maybe first thing in the morning, or by Noon, then head home right away. With the daily quota of 2, you’d get people sticking around for the rest of the day, trying to retain another one, or just wanting to catch and release until they have to go home. This would become especially frustrating on days when fish are concentrated at certain locations where people would just fence post all day.
