I think there was a thread a while back with people reporting the number of rivers or creeks they have caught fish in that are now completely closed for winter steelhead. My guess is that for some of us, 25 to 50% of the places we caught fish in are now closed completely, or at least closed for the later part of the season when winter run fish come in.
Some of these places were only good for one or two fish a year, catch and release, but timed right they were there. I went 2 for 3 on hatchery steelhead one day, a few years ago, on a small creek. Less than 10 hatchery strays show up there on a give year. That one is still open, most are not.
