Juro and Andre have pretty much got it covered - the SW Washington streams (and Andre's Oregon rivers) are the hot ones right now. I've also heard a few reports of early summers coming from the Peninsula, but not many.
The rivers up here around Seattle are mostly closed - the only open one is the NF Stilly. There are supposedly a few pods of native Spring fish still around, but I haven't gotten a chance to fish for them yet. The water has been high, too, so if you want to go check the levels with the USGS site as the lower/middle Stilly is our version of BC's Kispiox - the River Out~
